Abstract:

This thesis examines three issues which are of importance in the study of auditory word recognition: the phonological unit which is used to access representations in the mental lexicon; the extent to which hearers can rely on words being identified before their acoustic offsets; and the role of context in auditory word recognition. Three hypotheses which are based on the predictions of the Cohort Model (Marslen-Wilson and Tyler 1980) are tested experimentally using the gating paradigm. First, the phonological access hypothesis claims that word onsets, rather than any other part of the word, ar

Abstract:

Natural spoken language is full of disfluency. Around 10% of utterances produced in everyday speech contain disfluencies such as repetitions, repairs, filled pauses and other hesitation phenomena. The production of disfluency has generally been attributed to underlying problems in the planning and formulation of upcoming speech. However, it remains an open question to what extent factors known to affect the selection and retrieval of words in isolation influence disfluency production during connected speech, and whether different types of disfluency are associated with difficulties at differen

Abstract:

Vocabulary knowledge has been conceptualized as consisting of four components: the size of the mental lexicon, the depth or quality of knowledge of the individual lexical items in the lexicon, the degree to which those items are connected to each other (organlzation], and the speed at which those items can be retrieved and employed (e.g. Chapelle, 1998; Quian, 2002; Read, 2004; Schmitt, 2010b). There is now a considerable literature on each of the first three aspects, but lexical processing speed has hardly been explored outside the laboratory.

Abstract:

This dissertation addresses an unanswered question in Arabic psycholinguistics. Arabic words are characterized by their nonconcatenative structure, in which a consonantal root that encodes the main semantic content is interleaved with a derivational pattern (called "binyan", pl. "binyanim"), which is typically vocalic but may also contain consonantal elements and contributes grammatical information. The canonical example of the Semitic root and binyan system is the combination of root /ktb/ which denotes the broad semantic sense of "writing" with verbal binyan /CaCaC/ (with Cindicating a root

Abstract:

Lexical access in speech production involves multiple processing stages, beginning with the mental generation of a target concept and ending with a speaker's articulation of the target word. The current study aimed to explore the influence of competition and inhibition on the process of lexical access. In particular, the position of phonological overlap between a target word (e.g., lip) and its neighbors (e.g., lid vs. sip) was investigated for its influence on picture naming. It was hypothesized that greater inhibitory effects and slower response times in participants' naming would be observe

The present experiment was conducted to explore the facilitory effects of rhyme in lexical processing in brain-damaged individuals. Normal subjects and non-fluent and fluent aphasic subjects performed auditory lexical decision and rhyme judgement tasks, in which prime-target pairs were phonologically related (either identical or rhyming) or unrelated. Results revealed rhyme facilitation of lexical decisions to real-word targets for normal and non-fluent aphasic subjects; for fluent aphasic subjects, results were equivocal. In the rhyme judgement task, facilitory effects of rhyme were found for

Recent empirical studies about the neurological executive nature of reading in bilinguals differ in their evaluations of the degree of selective manifestation in lexical access as implicated by data from early and late reading measures in the eye-tracking paradigm.

Abstract:

Speaking can be considered a goal-directed behavior because speakers have to retrieve the appropriate words and phonemes from their mental lexicon. However, observational and experimental evidence suggests that during the lexical and phonological retrieval processes other words than the intended ones are activated to some degree. Under this scenario, it is necessary to postulate selection mechanisms in charge of determining, among the activated representations, which ones will be prioritized and further processed in order to finally utter the speech signal.

Abstract:

Verbal communication relies heavily on the ability to effortlessly produce intended words to express a meaning. This capacity is frequently impaired in individuals with aphasia, and impairment often lasts well into the chronic stages. However, the nature of anomia can vary. Phonological neighborhood density (PND) is one feature of words which has been shown to impact the ease of retrieval in speakers with aphasia; words with more similar-sounding neighbors are easier to retrieve because the neighbors help activate the target. However, it is unclear how different types of lexical access breakdo

Their performance was also studied in relation to demographic factors. The findings indicate that children with CI had visuospatial WM capacities equivalent to the comparison group.
