Full textAbstract:
Language production requires that semantic representations are mapped to lexical representations on the basis of the ongoing context to select the appropriate words. This mapping is thought to generate two opposing phenomena, “semantic priming,” where multiple word candidates are activated, and “interference,” where these word activities are differentiated to make a goal-relevant selection. In previous neuroimaging and neurophysiological research, priming and interference have been associated to activity in regions of a left frontotemporal network. Most of such studies relied on recordings that either have high temporal or high spatial resolution, but not both. Here, we employed intracerebral EEG techniques to explore with both high resolutions, the neural activity associated with these phenomena. The data came from nine epileptic patients who were stereotactically implanted for presurgical diagnostics. They performed a cyclic picture-naming task contrasting semantically homogeneous and heterogeneous contexts. Of the 84 brain regions sampled, 39 showed task-evoked activity that was significant and consistent across two patients or more. In nine of these regions, activity was significantly modulated by the semantic manipulation. It was reduced for semantically homogeneous contexts (i.e., priming) in eight of these regions, located in the temporal ventral pathway as well as frontal areas. Conversely, it was increased only in the pre-SMA, notably at an early poststimulus temporal window (200–300 msec) and a preresponse temporal window (700–800 msec). These temporal effects respectively suggest the pre-SMA's role in initial conflict detection (e.g., increased response caution) and in preresponse control. Such roles of the pre-SMA are traditional from a history of neural evidence in simple perceptual tasks, yet are also consistent with recent cognitive lexicosemantic theories that highlight top–down processes in language production. Finally, although no significant semantic modulation was found in the ACC, future intracerebral EEG work should continue to inspect ACC with the pre-SMA.

Full textAbstract:
ABSTRACTThis study examined the effects of lexical frequency on children's production of accurate primary stress in words derived with nonneutral English suffixes. Forty-four third-grade children participated in an elicited derived word task in which they produced high-frequency, low-frequency, and nonsense-derived words with stress-changing suffixes (i.e., -tion, -ic, -ity). Derived word frequency affected stress production accuracy; however, the individual suffix also played an important role in stress placement, with -tion productions more accurate than either -ic or -ity productions. For the real words, derived word frequency relative to stem frequency was related to performance. Stress was less accurate on derived words that were much lower in frequency than their stems (e.g., tranquil/tranquility) and more accurate on derived words that approximated or exceeded their stem frequency (e.g., motivate/motivation). In addition to derived word and stem frequency, results are discussed with reference to several phonological characteristics that may also influence stress production accuracy.

Full textAbstract:
In previous studies we have found that the writing of words (typing) is made up of a highly structured time course. Words are written using a course of accelerations and decelerations at certain points within the words. These points correlate highly with the syllabic word structure and also with the morphological structure. At the beginning of these subword units we find significantly higher latencies than within units. We therefore assume that written word production starts with a frame of the whole word, certain subword frames (according to the syllabic and morphological structure) and subsequent filling of the frames with segmental information. So the segmental information is not completely available at the beginning of a word or syllable but is delivered during motor execution. In the present study we try to find out if there are also subsyllabic units that are produced in a frame and content mode. As a candidate for such a unit we choose polygraphemes (e.g. in engl.in “think”, in germanin “schon”). If they are produced in this way we expect an increased delay at their onset and an accelaration within the unit. The results suggest that because of their grapho-phonological structure some types of complex graphemes are produced in a frame and content mode.

Full textAbstract:
Abstract The aim of the present study was to investigate relationships between characteristics of children’s target words and their actual productions during the single-word period in American English. Word productions in spontaneous and functional speech from 18 children acquiring American English were analyzed. Consonant sequences in 3,328 consonant-vowel-consonant (C1VC2) target words were analyzed in terms of global place of articulation (labials, coronals, and dorsals). Children’s actual productions of place sequences were compared between target words containing repeated place sequences (e.g., mom, map, dad, not) and target words containing variegated place sequences (e.g., mat, dog, cat, nap). Overall, when the target word contained two consonants at the same global place of articulation (e.g., labial-labial, map; coronal-coronal, not), approximately 50% of children’s actual productions matched consonant place characteristics. Conversely, when the target word consisted of variegated place sequences (e.g., mat, dog, cat, nap), only about 20% of the productions matched the target consonant sequences. These results suggest that children’s actual productions are influenced by their own production abilities as well as by the phonetic forms of target words.

Full textAbstract:
High rates of error and variability in early word production may signal speech sound disorder. However, there is little consensus regarding the degree of error and variability that may be expected in the typical range. Relatedly, while variables including child age, word frequency and word phonological neighbourhood density are associated with variance in word production accuracy and variability, such effects remain under-examined in spontaneous speech. This study measured the accuracy and variability of 234,551 spontaneous word productions from five typically developing children in the Providence corpus (0;11–4;0). Using Bayesian regression, accuracy and variability rates were predicted by age, input frequency, phonological neighbourhood density, and interactions between these variables. Between 61% and 72% of word productions were both inaccurate and variable according to strict criteria. However loosening these criteria to accommodate production inconsistencies unlikely to be considered erroneous (e.g. the target /æləɡeɪtəɹ/ pronounced /ælɪɡeɪtəɹ/) reduced this figure to between 10% and 17%, with the majority of word productions then classed as accurate and stable (48%–58%). In addition, accuracy was higher and variability was lower in later months of sampling, and for high frequency words and high density words. The author discusses the implications of these results for future research and the differential diagnosis of speech sound disorder, and presents an explanatory account of findings emphasizing the development of oral-motor skills and increasingly detailed phonological word representations.

Full textAbstract:
In this study, we investigated semantic context effects in language production with event-related brain potentials, extracted from the ongoing EEG recorded during overt speech production. We combined the picture–word interference paradigm and the semantic blocking paradigm to investigate the temporal dynamics and functional loci of semantic facilitation and interference effects. Objects were named in the context of semantically homogeneous blocks consisting of related objects and heterogeneous blocks consisting of unrelated objects. In each blocking condition, semantically related and unrelated distractor words were presented. Results show that classic patterns of semantically induced facilitation and interference effects in RTs can be directly related to ERP modulations located at temporal and frontal sites, starting at about 200 msec. Results also suggest that the processes associated with semantic facilitation and interference effects (i.e., conceptual and lexical processing) are highly interactive and coincide in time. Implications for the use of event-related brain potentials in speech production research and implications for current models of speech production are discussed.

Full textAbstract:
ABSTRACTProcesses involved in late bilinguals’ production of morphologically complex words were studied using an event-related brain potentials (ERP) paradigm in which EEGs were recorded during participants’ silent productions of English past- and present-tense forms. Twenty-three advanced second language speakers of English (first language [L1] German) were compared to a control group of 19 L1 English speakers from an earlier study. We found a frontocentral negativity for regular relative to irregular past-tense forms (e.g., asked vs. held) during (silent) production, and no difference for the present-tense condition (e.g., asks vs. holds), replicating the ERP effect obtained for the L1 group. This ERP effect suggests that combinatorial processing is involved in producing regular past-tense forms, in both late bilinguals and L1 speakers. We also suggest that this paradigm is a useful tool for future studies of online language production.

Full textAbstract:
Existing evidence is unclear as to how manual sign acquisition relates to the early development of spoken language. The relationship between signed and spoken word productions was examined in a young girl with Down Syndrome during a treatment regimen utilizing simultaneous input. All of her words were recorded over an 8-month period and classified according to the manner and modality of production (i.e., spontaneous/imitated; signed and/or spoken). Certain analyses revealed that most of the words that the subject initially signed were later spontaneously spoken and that most of her signed productions evolved into spontaneous spoken productions. Various patterns were demonstrated with respect to specific word evolutions (e.g., signed to spoken productions), and sign/spoken production tendencies during the first versus last four months of the investigation. It was concluded that use of simultaneous input supports the production of spoken language.

Full textAbstract:
Two visual world eye-tracking experiments examined the role of orthographic information in the visual context in pre-activation of orthographic and phonological information using Japanese. Participants heard sentences that contained a predictable target word and viewed a display showing four words in a logogram, kanji (Experiment 1) or in a phonogram, hiragana (Experiment 2). The four words included either the target word (e.g., 魚 /sakana/; fish), an orthographic competitor (e.g., 角 /tuno/; horn), a phonological competitor (e.g., 桜 /sakura/; cherry blossom), or an unrelated word (e.g., 本 /hon/; book), together with three distractor words. The orthographic competitor was orthographically or phonologically dissimilar to the target in hiragana. In Experiment 1, target and orthographic competitor words attracted more fixations than unrelated words before the target word was mentioned, suggesting that participants pre-activated orthographic form of the target word. In Experiment 2, target and phonological competitor words attracted more predictive fixations than unrelated words, but orthographic competitor words did not, suggesting a critical role of the visual context. This pre-activation pattern does not fit with the pattern of lexical activation in auditory word recognition, where orthography and phonology interact. However, it is compatible with the pattern of lexical activation in spoken word production, where orthographic information is not automatically activated, in line with production-based prediction accounts.

OBJECTIVES/GOALS: Speech production requires mapping between sound-based and motor-based neural representations of a word – accomplished by learning internal models. However, the neural bases of these internal models remain unclear. The aim of this study is to provide experimental evidence for these internal models in the brain during speech production. METHODS/STUDY POPULATION: 16 healthy human adults were recruited for this electrooculography speech study. 20 English pseudowords were designed to vary on confusability along specific features of articulation (place vs manner). All words were controlled for length and voicing. Three task conditions were performed: speech perception, covert and overt speech production. EEG was recorded using a 64-channel Biosemi ActiveTwo system. EMG was recorded on the orbicularis orbis inferior and neck strap muscles. Overt productions were recorded with a high-quality microphone to determine overt production onset. EMG during was used to determine covert production onset. Neuroimaging: Representational Similarity Analysis (RSA), was used to probe the sound- and motor-based neural representations over sensors and time for each task. RESULTS/ANTICIPATED RESULTS: Production (motor) and perception (sound) neural representations were calculated using a cross-validated squared Euclidean distance metric. The RSA results in the speech perception task show a strong selectivity around 150ms, which is compatible with recent human electrocorticography findings in human superior temporal gyrus. Parietal sensors showed a large difference for motor-based neural representations, indicating a strong encoding for production related processes, as hypothesized by previous studies on the ventral and dorsal stream model of language. Temporal sensors, however, showed a large change for both motor- and sound-based neural representations. This is a surprising result since temporal regions are believed to be primarily engaged in perception (sound-based) processes. DISCUSSION/SIGNIFICANCE: This study used neuroimaging (EEG) and advanced multivariate pattern analysis (RSA) to test models of production (motor-) and perception (sound-) based neural representations in three different speech task conditions. These results show strong feasibility of this approach to map how the perception and production processes interact in the brain.

Full textAbstract:
The cognitive architecture that allows humans to retrieve words from the mental lexicon has been investigated for decades. While there is consensus regarding a two-step architecture involving lexical-conceptual and phonological word-form levels of processing, accounts of how activation spreads between them (e.g., in a serial, cascaded, or interactive fashion) remain contentious. In addition, production models differ with respect to whether selection occurs at lexical or postlexical levels. The purpose of this study was to examine whether mediated phonological–semantic relations (e.g., drip is phonologically related to drill that is semantically related to hammer) influence production in adults as predicted by models implementing cascaded processing and feedback between levels. Two experiments using the picture–word interference (PWI) paradigm were conducted using auditory (Exp. 1) and written (Exp. 2) distractors. We hypothesised that a mediated semantic interference effect would be observable in the former with the involvement of both spoken word production and recognition, and in the latter if lexical representations are shared between written and spoken words in English, as assumed by some production accounts. Furthermore, we hypothesised a mediated semantic interference effect would be inconsistent with a postlexical selection account as the distractors do not constitute a relevant response for the target picture (e.g., drip-HAMMER). We observed mediated semantic interference only from auditory distractors, while observing the standard semantic interference effect from both auditory and written distractors. The current findings represent the first chronometric evidence involving spoken word production and recognition in support of cascaded processing during lexical retrieval in adults and present a significant challenge for the postlexical selection account.

Full textAbstract:
New theories of monitoring in language production, regardless of their mechanistic differences, all posit monitoring mechanisms that share general computational principles with action monitoring. This perspective, if accurate, would predict that many electrophysiological signatures of performance monitoring should be recoverable from language production tasks. In this study, we examined both error-related and feedback-related EEG indices of performance monitoring in the context of a typing-to-dictation task. To disentangle the contribution of the external from internal monitoring processes, we created a condition where participants immediately saw the word they typed (the immediate-feedback condition) versus one in which displaying the word was delayed until the end of the trial (the delayed-feedback condition). The removal of immediate visual feedback prompted a stronger reliance on internal monitoring processes, which resulted in lower correction rates and a clear error-related negativity. Compatible with domain-general monitoring views, an error positivity was only recovered under conditions where errors were detected or had a high likelihood of being detected. Examination of the feedback-related indices (feedback-related negativity and frontocentral positivity) revealed a two-stage process of integration of internal and external information. The recovery of a full range of well-established EEG indices of action monitoring in a language production task strongly endorses domain-general views of monitoring. Such indices, in turn, are helpful in understanding how information from different monitoring channels are combined.

Full textAbstract:
The current study examined the neural systems underlying lexically conditioned phonetic variation in spoken word production. Participants were asked to read aloud singly presented words, which either had a voiced minimal pair (MP) neighbor (e.g., cape) or lacked a minimal pair (NMP) neighbor (e.g., cake). The voiced neighbor never appeared in the stimulus set. Behavioral results showed longer voice-onset time for MP target words, replicating earlier behavioral results [Baese-Berk, M., & Goldrick, M. Mechanisms of interaction in speech production. Language and Cognitive Processes, 24, 527–554, 2009]. fMRI results revealed reduced activation for MP words compared to NMP words in a network including left posterior superior temporal gyrus, the supramarginal gyrus, inferior frontal gyrus, and precentral gyrus. These findings support cascade models of spoken word production and show that neural activation at the lexical level modulates activation in those brain regions involved in lexical selection, phonological planning, and, ultimately, motor plans for production. The facilitatory effects for words with MP neighbors suggest that competition effects reflect the overlap inherent in the phonological representation of the target word and its MP neighbor.

Full textAbstract:
Narrow phonetic transcriptions and prosodic judgments were made of single-word imitations by apraxic (AOS), conduction aphasic (CA), and ataxic dysarthric (AD) speakers. AOS and AD subjects showed similar vowel error patterns, particularly predominant errors in low, tense, and back vowels, more distortions than other types of vowel errors, and predominant errors in initial position of words and in monosyllabic words. The CA subjects displayed a different vowel error pattern, notably more substitutions than distortions, more errors in polysyllabic than monosyllabic words, and more errors in noninitial than initial positions of words. Analysis of prosodic features identifiable at the single-word level (e.g., syllabic stress, juncture, and struggles to initiate or complete productions) indicated that syllabic stress errors and more difficulty initiating than completing word production were characteristic of AOS and AD but not CA subjects.

Speech imagery is a form of mental imagery which refers to the activity of talking to oneself in silence. In this paper, EEG coherence, a functional connectivity parameter is calculated to analyze the concurrence of the different regions of the brain and Effective connectivity parameters such as Partial Directed Coherence (PDC), Directed Transfer Function (DTF) and Information theory based parameter Transfer Entropy (TE) are estimated to find the direction and strength of the connectivity patterns of the given speech imagery task. It has been observed from the results that by using functional and effective connectivity parameters the left frontal lobe electrodes was found to be high during speech production and left temporal lobe electrodes was found to be high while imagining the word silently in the brain due to the proximity of the electrodes to the Broca's and Wernicke's area respectively. The results suggest that the proposed methodology is a promising non-invasive approach to study directional connectivity in the brain between mutually interconnected neural populations.

Full textAbstract:
Surnames of celebrities that are English words (e.g. “Wood”, “Bush”, “Sleep”) were used to explore the relationship between production of common names and proper names that share the same phonology. No effect of priming of face naming latency was found from a prime task in which a written common name was presented and was read aloud, even when subjects were informed the words that they would read aloud were surnames. Production of common names to complete a sentence did not prime famous-face naming. However, the reaction time required to name a famous face by articulating the surname only was primed by seeing the written full name of the celebrity, whether the surname was read aloud or an occupation decision or a familiarity decision was made. No effect of priming was found if the test task did not require name production. The results are interpreted in terms of the information-processing model of face, name, and word recognition proposed by Valentine, Brédart, Lawson, and Ward (1991). It is concluded that the effect of repetition reflects greater accessibility of lexical output codes resulting from an increase in the weight on links from person identity nodes to the output lexicon. Access to the output lexicon is assumed to be mandatory from written input. Common names access the output lexicon from the word recognition system rather than the person recognition system and therefore do not prime face naming latency.

Full textAbstract:
High word frequency and neighborhood density contribute to the accuracy and speed of word production in English adults (e.g., Vitevitch & Sommers 2003), and characterize early words in child English (e.g., Storkel 2004). The present study investigated a speech corpus of child German (ages 2;00-3;00) to further the understanding of the influence of frequency and density on production. Results for four children suggest that, contrary to English, words produced early are not from denser neighborhoods in an adult lexicon than later words. As in English, frequent words are produced before less frequent words. Implications on theory and methodology are discussed.

Cortical preparation for movement is reflected in the readiness potential (RP) waveform preceding voluntary limb movements. In the case of oral movements, the RP may be affected by the complexity or linguistic nature of the tasks. In this experiment, EEG potentials before a nonspeech task (lip pursing), a speech-like task (lip rounding), and single word production were recorded from scalp electrodes placed at the cranial vertex (Cz) and over the left and right motor strips (C3′ and C4′). Seven right-handed female subjects produced at least 70 repetitions of the three tasks, in each of five repeated sessions. EEG records were averaged with respect to EMG onset at the lip. The word task, as opposed to the other tasks, was associated with greater negative amplitude in the RP waveform at the vertex site. Differences between the waveforms recorded at the rightand left-hemisphere sites were insignificant. Although intersubject variability was high, individuals had relatively stable patterns of response across sessions. Results suggest that the RP recorded at the vertex site is sensitive to changes in task complexity. The RP did not reflect lateralized activity indicative of hemispheric dominance.

Normally capable children were first taught to touch in sequence each of a set of five physically dissimilar stimuli (Sequence A). Another set of stimuli was then used to train sequence B. Next, direct training established conditional control of the production of the A sequence and its reversal: in the presence of one printed word, touching the stimuli in the order A1→A2→A3→A4→A5 was reinforced; in the presence of another word, touching the stimuli in the order A5→A4→A3→A2→A1 was reinforced. During probe sessions, the printed words also exercised conditional control over production of the B sequence and its reversal for five of six subjects, suggesting the formation of stimulus classes. Four of these five subjects also performed mixed sequences under conditional control of the words (e.g., A1→B2→A3→B4→A5 and its reversal), verifying that the stimuli which occupied the same position in each sequence were members of the same class.

Full textAbstract:
During conversation, speakers monitor their own and others' output so they can alter their production adaptively, including halting it if needed. We investigated the neural mechanisms of monitoring and halting in spoken word production by employing a modified stop signal task during fMRI. Healthy participants named target pictures and withheld their naming response when presented with infrequent auditory words as stop signals. We also investigated whether the speech comprehension system monitors inner (i.e., prearticulatory) speech via the output of phonological word form encoding as proposed by the perceptual loop theory [Levelt, W. J. M. Speaking: From intention to articulation. Cambridge, MA: MIT Press, 1989] by presenting stop signals phonologically similar to the target picture name (e.g., cabbage–CAMEL). The contrast of successful halting versus naming revealed extensive BOLD signal responses in bilateral inferior frontal gyrus, preSMA, and superior temporal gyrus. Successful versus unsuccessful halting of speech was associated with increased BOLD signal bilaterally in the posterior middle temporal, frontal, and parietal lobes and decreases bilaterally in the posterior and left anterior superior temporal gyrus and right inferior frontal gyrus. These results show, for the first time, the neural mechanisms engaged during both monitoring and interrupting speech production. However, we failed to observe any differential effects of phonological similarity in either the behavioral or neural data, indicating monitoring of inner versus external speech might involve different mechanisms.

Abstract This study examined beginner-level Chinese as a Foreign Language (CFL) learners’ production of newly learned words in an image naming and pinyin-reading task. Fifteen L1-English CFL learners learned 10 tonal monosyllabic minimal pairs (e.g., shu1 and shu3) in a three-day sound-image word learning experiment. Ten of the 20 words were homophonous with previously learned words (e.g., participants already knew that shu1 means ‘book’), while the other 10 were not (e.g., no shu3 words had been learned). Ten of the 20 words had frequent phonology participants were familiar with (e.g., shi is a high token frequency syllable), while the other 10 had infrequent phonology (e.g., ku is a low token frequency syllable). On the last day of learning, participants performed an image naming task followed by a pinyin-reading task. The recoded word tokens from both tasks were then played to 10 native Chinese speakers who were asked to transcribe the words in pinyin. The results showed that overall word production in the pinyin-reading task was more accurate than image naming. The pinyin-reading advantage was robust, but homophone status and syllable token frequency also interacted with task type: learners produced syllables with high token frequency but without homophones equally well in the pinyin-reading and naming tasks. These results suggest phonological encoding in long-term memory based on pinyin orthography can be affected by learners’ prior phonological and lexical knowledge. Pedagogical applications and limitations of the study are discussed, as well.

Full textAbstract:
There is a range of variability in the speed with which a single speaker will produce the same word from one instance to another. Individual differences studies have shown that the speed of production and the ability to maintain attention are related. This study investigated whether fluctuations in production latencies can be explained by spontaneous fluctuations in speakers' attention just prior to initiating speech planning. A relationship between individuals' incidental attentional state and response performance is well attested in visual perception, with lower prestimulus alpha power associated with faster manual responses. Alpha is thought to have an inhibitory function: Low alpha power suggests less inhibition of a specific brain region, whereas high alpha power suggests more inhibition. Does the same relationship hold for cognitively demanding tasks such as word production? In this study, participants named pictures while EEG was recorded, with alpha power taken to index an individual's momentary attentional state. Participants' level of alpha power just prior to picture presentation and just prior to speech onset predicted subsequent naming latencies. Specifically, higher alpha power in the motor system resulted in faster speech initiation. Our results suggest that one index of a lapse of attention during speaking is reduced inhibition of motor-cortical regions: Decreased motor-cortical alpha power indicates reduced inhibition of this area while early stages of production planning unfold, which leads to increased interference from motor-cortical signals and longer naming latencies. This study shows that the language production system is not impermeable to the influence of attention.

Full textAbstract:
A domain-general monitoring mechanism is proposed to be involved in overt speech monitoring. This mechanism is reflected in a medial frontal component, the error negativity (Ne), present in both errors and correct trials (Ne-like wave) but larger in errors than correct trials. In overt speech production, this negativity starts to rise before speech onset and is therefore associated with inner speech monitoring. Here, we investigate whether the same monitoring mechanism is involved in sign language production. Twenty deaf signers (American Sign Language [ASL] dominant) and 16 hearing signers (English dominant) participated in a picture–word interference paradigm in ASL. As in previous studies, ASL naming latencies were measured using the keyboard release time. EEG results revealed a medial frontal negativity peaking within 15 msec after keyboard release in the deaf signers. This negativity was larger in errors than correct trials, as previously observed in spoken language production. No clear negativity was present in the hearing signers. In addition, the slope of the Ne was correlated with ASL proficiency (measured by the ASL Sentence Repetition Task) across signers. Our results indicate that a similar medial frontal mechanism is engaged in preoutput language monitoring in sign and spoken language production. These results suggest that the monitoring mechanism reflected by the Ne/Ne-like wave is independent of output modality (i.e., spoken or signed) and likely monitors prearticulatory representations of language. Differences between groups may be linked to several factors including differences in language proficiency or more variable lexical access to motor programming latencies for hearing than deaf signers.

Full textAbstract:
Word-production theories argue that during language production, a concept activates multiple lexical candidates in left temporal cortex, and the intended word is selected from this set. Evidence for theories on spoken-word production comes, for example, from the picture-word interference task, where participants name pictures superimposed by congruent (e.g., picture: rabbit, distractor “rabbit”), categorically related (e.g., distractor “sheep”), or unrelated (e.g., distractor “fork”) words. Typically, whereas congruent distractors facilitate naming, related distractors slow down picture naming relative to unrelated distractors, resulting in semantic interference. However, the neural correlates of semantic interference are debated. Previous neuroimaging studies have shown that the left mid-to-posterior STG (pSTG) is involved in the interference associated with semantically related distractors. To probe the functional relevance of this area, we targeted the left pSTG with focal repetitive transcranial magnetic stimulation (rTMS) while subjects performed a picture-word interference task. Unexpectedly, pSTG stimulation did not affect the semantic interference effect but selectively increased the congruency effect (i.e., faster naming with congruent distractors). The facilitatory TMS effect selectively occurred in the more difficult list with an overall lower name agreement. Our study adds new evidence to the causal role of the left pSTG in the interaction between picture and distractor representations or processing streams, only partly supporting previous neuroimaging studies. Moreover, the observed unexpected condition-specific facilitatory rTMS effect argues for an interaction of the task- or stimulus-induced brain state with the modulatory TMS effect. These issues should be systematically addressed in future rTMS studies on language production.

Full textAbstract:
The influence of an adult-child discourse structure on the production of early word combinations was examined in language-impaired children. The subjects were 10 children (2:8–3:4) at the single-word utterance level. Eight of the children were engaged in 10 experimental sessions utilizing vertical structures (e.g., Adult: "Who's this?" Child: "Daddy." Adult: "What's Daddy throwing?" Child: "Ball." Adult: "Yeah, Daddy's throwing the ball."), while the remaining children, serving as controls, were engaged in an alternate activity. Examination of pretest and posttest data as well as session data revealed a substantial increase in the number of multiword productions for most of the children in the experimental group but not for the children serving as controls. These findings indicate that vertical structures have a facilitating effect on the multiword productions of language-impaired children comparable to that found in an identical procedure with normally developing children. The use of a naturally occurring adult-child discourse structure as an intervention procedure is discussed.

Full textAbstract:
When faced with communication challenges talker often modify their way of speaking producing clear speech. In a production study we investigated how American English talkers adapt medial flaps (e.g., petal and pedal are pronounced as [ˈpɛɾəl]) following miscommunications with a computer partner. When subjects said a word (e.g., petal) the computer either interpreted the word correctly or incorrectly (it guesses pedal, kettle or ???). Talkers produced longer words, vowels, and stop closure in response to an incorrect versus correct guess. Talkers also changed their flapped productions to stops and lengthened stop closures more following voicing errors compared to other error types. Thus, talkers’ adjustments appear to depend on the miscommunication type. Next, we investigated how listener perceptions were influenced by the talkers’ adjustments. Listeners heard talkers’ productions and indicated what they heard. Listener perception was more accurate for lengthened compared to shortened productions and better for stops than flaps. However, listeners misperceived /d/ for /t/ when talkers lengthened their /d/ closures. Moreover, production changes talkers made following a misrecognition improved listener perception for medial /t/, but not medial /d/, which was at-chance. These findings indicate that talker adjustments made to remedy a misrecognition do not universally aid listeners’ perception.

Full textAbstract:
The present paper reports on the phonological form of one child's productive vocabulary from age 0;10 to 1;8 with primary focus on his production of multisyllabic targets. A large percentage of his multisyllabic vocabulary was produced as one syllable until the age of 1;6. This limitation was not due to a tendency to extract only single syllables from the speech stream, but rather due primarily to a limitation on production. While some portion of his one-syllable productions could be interpreted as the result of single syllable extraction, a sizeable portion affirmed that he extracted the target size correctly by his inclusion of first and final target phonemes in his productions (e.g. [po] for piano and [kiz] for candies). The resolution of this limitation coincides with his move toward two-word speech. We conclude that there is a developmental and perhaps maturational limitation in the capacity to carry out the processes underlying word and sentence production.

Full textAbstract:
Researchers have learned much about the cognitive organization of the language system by studying speech errors made by speakers with and without aphasia. Some aspects of errors made in language production reflect linguistic properties of language (e.g., linguistic similarities between an intended word and the word that was produced in error). Other aspects reflect processes that enable production of language (e.g., substitutions or sequencing errors). A particularly intriguing class of error is perseveration, the unintended retrieval of words or sounds after they have been recently produced. Although the occurrence of perseverations is influenced by both linguistic and processing aspects of language production, these errors have been particularly instructive about the latter aspect. Martin and Dell (2007) proposed that word and sound perseverations result from the same mechanisms as non-perseverative substitutions: slowed activation of the intended utterance and linguistic similarity between the target and error. They differ from non-perseverative substitutions in their probability of occurrence, which is increased by residual activation following their recent production. In this article, I will review this account of perseverations and discuss its implications for treatment approaches to reduce perseverations.

Full textAbstract:
This paper depicts a comprehensive picture of consonants of Pakistani English (PakE). The study shows that PakE speakers neutralize aspiration contrast in English stops. In the PakE, /t/ in /st/ cluster on onset of a word (e.g., steal) is produced with more aspiration than that on syllable-initial position without preceding /s/ (e.g., in “teach”). Besides, /t d/ are produced with strong retroflexion but /t/ in tautosyllabic /st/ clusters on word-initial position is produced without retroflexion. Voiced stops are produced with pre-voicing. Dental fricatives /θ ð/ produced by native speakers of English are perceived as [f z] or [s v] by PakE speakers but they produce these fricatives as stop. PakE speakers can realize a difference between clear and dark lateral of English in perception although they do not maintain the same difference in production as they produce English lateral as a clear lateral on onset and coda of syllables. Coronal fricative /ʒ/ is perceived and produced as approximant /j/ and /v w/ as a labial approximant. In PakE [r] is produced with strong trilling and rhoticity on all word-positions.

Full textAbstract:
In three experiments, participants named environmental sounds (e.g., the bleating of a sheep by producing the word “sheep”) in the presence of distractor pictures. In Experiment 1, we observed faster responses in sound naming with congruent pictures (e.g., sheep; congruency facilitation) and slower responses with semantically related pictures (e.g., donkey; semantic interference), each compared with unrelated pictures (e.g., violin). In Experiments 2 and 3, we replicated these effects and used a psychological refractory period approach (combining an arrow decision or letter rotation task as Task 1 with sound naming as Task 2) to investigate the locus of the effects. Congruency facilitation was underadditive with dual-task interference suggesting that it arises, in part, during pre-central processing stages in sound naming (i.e., sound identification). In contrast, semantic interference was additive with dual-task interference suggesting that it arises during central (or post-central) processing stages in sound naming (i.e., response selection or later processes). These results demonstrate the feasibility of sound naming tasks for chronometric investigations of word production. Furthermore, they highlight that semantic interference is not restricted to the use of target pictures and distractor words but can be observed with quite different target–distractor configurations. The experiments support the view that congruency facilitation and semantic interference reflect some general cognitive mechanism involved in word production. These results are discussed in the context of the debate about semantic-lexical selection mechanisms in word production.

Abstract Complex nominals (CNs) are frequently found in specialized discourse in all languages, since they are a productive method of creating terms by combining existing lexical units. In Spanish, a conceptual combination may often be rendered with a prepositional CN (PCN) or an equivalent adjectival CN (ACN), e.g., demanda de electricidad vs. demanda eléctrica [electricity demand]. Adjectives in ACNs – usually derived from nouns – are known as ‘relational adjectives’ because they encode semantic relations with other concepts. With recent exceptions, research has focused on the underlying semantic relations in CNs. In natural language processing, several works have dealt with the automatic detection of relation adjectives in Romance and Germanic languages. However, there is no discourse studies of these CNs, to our knowledge, for the goal of establishing writer recommendations. This study analyzed the co-text of equivalent PCNs and ACNs to identify factors governing the use of a certain form. EcoLexicon ES, a corpus of Spanish environmental specialized texts, was used to extract 6 relational adjectives and, subsequently, a set of 12 pairs of equivalent CNs. Their behavior in co-text was analyzed by querying EcoLexicon ES and a general language corpus with 20 expressions in CQP-syntax. Our results showed that immediate linguistic co-text determined the preference for a particular structure. Based on these findings, we provide writing guidelines to assist in the production of CNs.

Full textAbstract:
This investigation examined the influence of metrical patterns of words (syllable stress and serial position) on the production accuracy of 20 children (22 to 28 months). The data were productions of six pairs of individualized two-syllable experimental words that referred to unfamiliar objects. Members of each pair differed only in the placement of stress (e.g., ['soti] vs. [so'ti]). Unstressed syllables were much more likely to be omitted, particularly at the beginning of words. Very few stressed syllables and unstressed second position syllables were omitted. One fourth of the word initial unstressed syllables were omitted. Consonant omissions, though few in number, tended to occur in initial position. Assimilation errors were not influenced by stress or serial position. When segmental errors due to syllable omissions were excluded, other consonant errors were not affected by stress or serial position. These findings indicate that young children's productions of syllables are influenced by the metrical patterns of words. However, the trochaic pattern of English is a statistical tendency, not an absolute constraint on two-syllable words. Metrical pattern also does not affect the consonant accuracy in syllables produced.

Full textAbstract:
Recent work has shown that exposure to orthographic effects can promote first-language (L1) phonological transfer. However, it is relatively unknown whether orthographic effects persist in highly proficient bilinguals. Here, we examined how L1 orthographic depth (regularity in grapheme-phoneme correspondences) modulated Korean-English and Farsi-English bilinguals’ (n = 25 each) production of fricatives in English words (e.g., <mellow> /ˈmeloʊ/ vs. <melon> /ˈmelən/). Native English speakers (n = 25) served as a control group. Because fricatives are produced as geminate sounds in both Korean and Farsi, we expected L1-based transfer. Participants completed four tasks: an eye-movement reading task, word-naming task, cloze test, and language background questionnaire. The stimuli were controlled for word frequency, word length, number of syllables, and stress. We expect language-specific differences, corroborating previous neuro-linguistic evidence that shallow and deep orthographies differentially rely more heavily on phonological and lexical pathways, depending on language-specific demands. To explore this aspect, we employed an acoustic classification method for fricatives extracting cepstral coefficients and using HMMs to divide the sounds in regions based on their internal variance, aimed at determining whether fricatives produced by different groups can be classified correctly. This work has implications for both second-language (L2) speech learning models and classroom instruction.

Full textAbstract:
One key issue in bilingualism is how bilinguals control production, particularly to produce words in the less dominant language. Language switching is one method to investigate control processes. Language switching has been much studied in comprehension, e.g., in lexical decision task, but less so in production. Here we first present a study of language switching in Italian–English adult bilinguals in a naming task for visually presented words. We demonstrate an asymmetric pattern of time costs to switch language, where participants incurred a greater time cost to switch into naming in their dominant language (Italian). In addition, costs were greater where the stimuli were interlingual cognates or homographs than words existing in only one language, implicating lexical competition as a source of the cost. To clarify the operation of control processes, we then present two connectionist models of bilingual naming, based on the previous models of Seidenberg and McClelland (1989), Cohen, Dunbar and McClelland (1990), Gilbert and Shallice (2002), and Karaminis and Thomas (2010). Crucially, both models acquired their differential language dominance via an experience-dependent learning process. The models embody different assumptions about the language control processes that produce the switch cost. We consider which processing assumptions are sufficient to explain asymmetric language switch costs and word class effects on language switching in individual word reading, as well as generating novel predictions for future testing.

Full textAbstract:
Heritage speakers exhibit a tendency to overgeneralize morphological paradigms in their production, but little is known about their perception, and the present study seeks to better understand how heritage speakers process new information in their home language. To this end, 119 listeners from different language backgrounds evaluated the number of syllables in 70 nonce words, all four-syllable paroxytone nonce words with an initial obstruent + vowel + flap sequence, with the first vowel presented at 100%, 75%, 50%, and 25% of its original duration. Two types of word endings were used: -fono, designed to be reminiscent of the word teléfono, a high frequency four-syllable word, and -pine, which does not clearly prime any existing Spanish words, e.g. teréfono and terépine, respectively. Cumulative link mixed effects models fitted to 119 participants’ evaluations (N = 32,619) show that heritage speakers evaluate nonce words ending in -fono as four syllables significantly more than words ending in -pine (p < 0.001), but no word-ending effect was found for any other language group. I contend that heritage speakers filter new information in their heritage language through existing knowledge more rigidly than other Spanish speakers, and these overgeneralizations in perception parallel heritage speakers’ overgeneralizations in production.

Full textAbstract:
Abstract Hydraulic fracturing and waterjet slotting fracturing have been demonstrated to be effective in creating artificial fractures and stimulating gas production in hard coal seams. However, these methods are inefficient for soft-outburst coal seams because these created fractures are short and easy to close. To eliminate the outburst risk of soft coals, a novel enhanced coalbed methane under-panel cross-strata drainage technique via hydraulic flushing was proposed in this work. The hydraulic flushing effects of boreholes of different sizes in the coal seam were also pre-evaluated by a simulation approach. The modeling results indicate that as the radius of the borehole increases, the plastic and stress-decreasing zone expands. A field test was also conducted in the Minjin mine, China, that investigated the gas pressure variation between three monitoring boreholes at different distances from a hydraulic flushing borehole. Test results indicate that the effective influence radius of gas extraction is approximately 5.5 m. Based on the results of the field test and borehole camera observation, the unloaded coal quantity and the average diameter of the boreholes were estimated to be 8.0 t and 942 mm, respectively. The borehole diameter expanded up to 10 times larger than its original size. The average gas extraction concentration and gas flow rate increased by approximately 2 and 3.5 times, respectively, demonstrating the effectiveness of the proposed hydraulic flushing in improving the gas extraction efficiency. The hydraulic flushing technique therefore is proved to be efficient in eliminating the outburst risk of coal and reducing greenhouse gas emissions.

Contrary to what is stated in much of the literature which is based in large part on Parisian French, many dialects of French still have long and short vowels (e.g. in Switzerland and Belgium). This study had two aims. The first was to show that Swiss French speakers, as opposed to Parisian French speakers, produce long vowels with durations that are markedly different from those of short vowels. The second aim was to show that, for these two groups, vowel duration has a different impact on word recognition. A production study showed that Swiss French speakers make a clear duration difference between short and long vowels (the latter are more than twice the length of the former on average) whereas the Parisian French do not. In an identification study which used stimuli pronounced in Swiss French, it was shown that words articulated with long vowels created no recognition problem for Swiss French listeners whereas they did so for Parisian French listeners. These results are discussed in terms of models of speech perception and word recognition.

Full textAbstract:
Planning to speak is a challenge for the brain, and the challenge varies between and within languages. Yet, little is known about how neural processes react to these variable challenges beyond the planning of individual words. Here, we examine how fundamental differences in syntax shape the time course of sentence planning. Most languages treat alike (i.e., align with each other) the 2 uses of a word like “gardener” in “the gardener crouched” and in “the gardener planted trees.” A minority keeps these formally distinct by adding special marking in 1 case, and some languages display both aligned and nonaligned expressions. Exploiting such a contrast in Hindi, we used electroencephalography (EEG) and eye tracking to suggest that this difference is associated with distinct patterns of neural processing and gaze behavior during early planning stages, preceding phonological word form preparation. Planning sentences with aligned expressions induces larger synchronization in the theta frequency band, suggesting higher working memory engagement, and more visual attention to agents than planning nonaligned sentences, suggesting delayed commitment to the relational details of the event. Furthermore, plain, unmarked expressions are associated with larger desynchronization in the alpha band than expressions with special markers, suggesting more engagement in information processing to keep overlapping structures distinct during planning. Our findings contrast with the observation that the form of aligned expressions is simpler, and they suggest that the global preference for alignment is driven not by its neurophysiological effect on sentence planning but by other sources, possibly by aspects of production flexibility and fluency or by sentence comprehension. This challenges current theories on how production and comprehension may affect the evolution and distribution of syntactic variants in the world’s languages.

In this article, we present the Nordic Word Order Database (NWD), with a focus on the rationale behind it, the methods used in data elicitation, data analysis and the empirical scope of the database. NWD is an online database with a user-friendly search interface, hosted by The Text Laboratory at the University of Oslo, launched in April 2019 (https://tekstlab.uio.no/nwd). It contains elicited production data from speakers of all of the North Germanic languages, including several different dialects. So far, 7 fieldtrips have been conducted, and data from altogether around 250 participants (age 16–60) have been collected (approx. 55 000 sentences in total). The data elicitation is carried out through a carefully controlled production experiment that targets core syntactic phenomena that are known to show variation within and/or between the North Germanic languages, e.g., subject placement, object placement, particle placement and verb placement. In this article, we present the motivations and research questions behind the database, as well as a description of the experiment, the data collection procedure, and the structure of the database

Full textAbstract:
ABSTRACTIn spoken French, the phonological processes of liaison and resyllabification can render word and syllable boundaries ambiguous (e.g.,un air“an air”/un nerf“a nerve,” both [.nɛʁ]). Production data have demonstrated that speakers of French vary the duration of consonants that surface in liaison environments relative to consonants produced word initially. Further research has suggested that listeners exploit these durational differences in the processing of running speech, although no study to date has directly tested this hypothesis. The current study examines the exploitation of duration in word recognition processes by manipulating this single acoustic factor while holding all other factors in the signal constant. The pivotal consonants in potentially ambiguous French sequences (e.g., /n/ inun nerf) were instrumentally shortened and lengthened and presented to listeners in two behavioral tasks. The results suggest that listeners are sensitive to segmental duration and use this information to modulate the lexical interpretation of spoken French.

Full textAbstract:
Abstract Previous research suggests that different types of word-final /s/ and /z/ (e.g. non-morphemic vs. plural or clitic morpheme) in English show realisational differences in duration. However, there is disagreement on the nature of these differences, as experimental studies have provided evidence for durational differences of the opposite direction as results from corpus studies (i.e. non-morphemic > plural > clitic /s/). The experimental study reported here focuses on four types of word-final /s/ in English, i.e. non-morphemic, plural, and is- and has-clitic /s/. We conducted a pseudoword production study with native speakers of Southern British English. The results show that non-morphemic /s/ is significantly longer than plural /s/, which in turn is longer than clitic /s/, while there is no durational difference between the two clitics. This aligns with previous corpus rather than experimental studies. Thus, the morphological category of a word-final /s/ appears to be a robust predictor for its phonetic realisation influencing speech production in such a way that systematic subphonemic differences arise. This finding calls for revisions of current models of speech production in which morphology plays no role in later stages of production.

AbstractOnomatopoeia are frequently identified amongst infants’ earliest words (Menn & Vihman, 2011), yet few authors have considered why this might be, and even fewer have explored this phenomenon empirically. Here we analyze mothers’ production of onomatopoeia in infant-directed speech (IDS) to provide an input-based perspective on these forms. Twelve mothers were recorded interacting with their 8-month-olds; onomatopoeic words (e.g. quack) were compared acoustically with their corresponding conventional words (duck). Onomatopoeia were more salient than conventional words across all features measured: mean pitch, pitch range, word duration, repetition, and pause length. Furthermore, a systematic pattern was observed in the production of onomatopoeia, suggesting a conventionalized approach to mothers’ production of these words in IDS.

AbstractThis study investigates the effect of an abstract word training paradigm initially developed to treat lexical retrieval deficits in patients with aphasia on second language (L2) vocabulary acquisition. Three English–Spanish L2 learners (Experiment 1) and 10 Spanish–English L2 learners (Experiment 3) were trained on 15 abstract words within a context-category (e.g., restaurant) using a five-step training paradigm based on semantic feature analysis. In addition, 7 English–Spanish L2 learners were trained on either abstract or concrete words within a context-category (Experiment 2). Across all experiments, the majority of participants trained on abstract words showed improved production of the trained abstract words, as measured by a word generation task, as well as improvement on untrained concrete words within the same context-category (i.e., generalization). Participants trained on concrete words (Experiment 2) exhibited much smaller word production gains and no generalization to abstract words. These results parallel previous findings from aphasia research and suggest that this training paradigm can successfully be extended to L2 learning contexts, where it has the potential to be a useful tool in vocabulary instruction. We discuss the findings in terms of models of spreading activation and the underlying conceptual representations of abstract and concrete words in the L2 lexicon.

Wider exploitation of computer integrated manufacturing (CIM) in shipbuilding is inevitable as yards seek continuing improvements in productivity and quality to sharpen competitiveness. The buzz word CIM has been used in many ways through the years. The correct interpretation may be the integration of all computer systems directly supporting the definition and production of the ship. This comprises CAD and also administrative systems such as planning and material control programs. CIM in this paper is defined as optimal utilization of CAD data and planning data in shop floor production, including feedback to the planning system and accumulation of quality data. The paper defines the state-of-the-art of CIM solutions at shipyards, and outlines a case study of one larger CIM installation. The case presented shows the structure of one installed system, and outlines the experience gained through planning, preparation and installation of the system. The case also includes cost budgets for the installation, including necessary training for planners and operators. Important organizational issues when planning the structure of CIM based production is described in the case. Terms such as Central Work Preparation and Local Work Preparation are introduced. The tasks performed in each area that add value to the CIM data files are described. At the end of the paper, the authors have outlined some future thoughts on further developments of CIM at shipyards. Important issues are, e.g., on-line production simulation systems capable of constantly updating the planning system in order to ensure the highest possible productivity and to support just in time (JIT) philosophies in all areas of the production.

Full textAbstract:
Purpose This retrospective pilot study investigated whether sound-level and speech production errors decreased in confrontation naming following Verb Network Strengthening Treatment (VNeST) for four participants with acquired apraxia of speech (A-AOS) and aphasia for whom lexical retrieval was previously reported. Specifically, we investigated a potential increase in correct number of syllables per word and posttreatment changes across three domains of speech: segmental production, fluency, and prosody. It was hypothesized that treatment shown to increase lexical retrieval in persons with aphasia and A-AOS could potentially facilitate a reduction in sound-level and speech production errors consistent with dual diagnoses of A-AOS and aphasia. Method Naming responses from four participants with aphasia and A-AOS who previously participated in VNeST studies were investigated for correct number of syllables per word and measures of segmental speech, fluency, and prosody. Results Significant gains in at least one measure of speech production were reported for three of the participants. One participant demonstrated decreased segmental speech errors, two showed significant reduction on syllable segmentation, and two demonstrated a significant reduction on false starts and pauses. Significant gains in production of correct number of syllables were limited to one participant, and one participant did not demonstrate increased accuracy on any measure of speech production. Conclusions While speech production errors consistent with motor speech impairment cannot always be definitively distinguished from the confound of aphasia, two participants produced significantly decreased segmentation of syllables, a characteristic unique to A-AOS. The sound-level and speech production changes recorded may be attributed to a combination of interacting motor and language processes and resource allocation. In addition, specific components of VNeST may have contributed to speech production changes. Future work will focus on a prospective study of effects of language therapy (e.g., VNeST) on measures of speech production with investigation beyond the single-word level.

Full textAbstract:
AbstractUsage-based approaches to language acquisition posit that first (L1) and second language (L2) speakers should process more frequent compositional phrases, which have a meaning derivable from word parts, faster than less frequent ones (e.g., Bybee, 2010; Ellis, 2011). Although this prediction has received increasing empirical support, methodological limitations in previous relevant studies include a lack of control of frequencies of subparts of target phrases and scant attention to L2 production. Addressing these limitations, the current study tested phrase frequency effects in both language comprehension and production in two respective experiments, in which adult native English speakers (N= 51) and English L2 learners (N= 52) completed a timed phrasal decision task and an elicited oral production task. Experiment 1 revealed phrase frequency effects in both groups, lending support to usage-based researchers’ proposal that L1 and L2 speakers retain memory of word co-occurrences and that compositional phrase processing reflects an accumulation of statistics in previously encountered input. Experiment 2, however, provided weaker evidence for phrase frequency effects in these participant groups. Based on the results and previous empirical studies, methodological issues that may have impacted frequency effects and implications for future work in this area are discussed.

Full textAbstract:
There are two competing theories of bilingual lexical access — the language-selective access theory, which proposes that only the lexical items from the intended language are activated for selection during speech planning and comprehension (e.g., Costa, Santesteban, & Ivanova, 2006), and the language non-selective access theory, which proposes that both languages receive activation and compete for production (e.g., Kroll, Bobb, & Wodniecka, 2006). This study examines whether language-specific syntax — the syntactic positioning of a target word in a determiner phrase — can act as a language cue to modulate cross-linguistic activation and whether inhibition resolves competition (e.g., Green, 1998). In two cross-modal priming (+/−Rep) tasks, Spanish-English bilinguals were presented English sentences that were linearly congruent (Canonical Dative and of-Genitive) or incongruent (Dative Double Object and ’s-Genitive) with Spanish syntax and were prompted to make a lexical decision on a Spanish translation of the target word or a control word. The RTs revealed that participants were significantly slower in the incongruent condition (−Rep) than the congruent condition (−Rep) suggesting that language-specific syntax is a language cue that modulates cross-linguistic activation. When participants were prompted to repeat the sentences aloud (+Rep), the translation equivalent was expected to compete with the target word for production, yet no significant difference of RTs was found and the role of inhibition in speech production was not confirmed. Taken together, these findings support the language non-selective access model and further refine current theories of cross-linguistic activation and inhibitory control during bilingual language comprehension and production.
