Gonzalez, Daniel. "An Adaptation of an Auditory Perception Test." FIU Digital Commons, 2018. https://digitalcommons.fiu.edu/etd/3772.
Full textAbstract:
The Auditory Perception Test for the Hearing Impaired, 3rd edition (APT/HI-3) was adapted into an auditory perception assessment tool for Spanish-speaking children called the Auditory Perception Test for the Hearing Impaired—Spanish (APT/HI-S). Test items from the APT/HI-S were then validated by three groups of Spanish-English bilinguals to determine if selected words were developmentally and linguistically appropriate for 3-year old children. Survey results revealed that 37 out of 62 words were considered developmentally and grammatically appropriate. The APT/HI-S was then administered to two 3-year old and two 5-year old children, two with typical hearing and two with hearing loss. Results revealed that language proficiency played an integral role in the measurement of auditory perception skills. The children demonstrated better performance when tested in their dominant language, reinforcing the need to have a language-specific assessment tool to obtain a more accurate picture of auditory and speech perception skills in children.

Syftet med detta examensarbete är att undersöka lärares uppfattningar om det nationella provet i engelska, samt hur dessa lärare arbetar med provet för att kunna hjälpa eleverna att nå sina kursmål. Undersökningsmetoden är kvalitativ då vi intervjuat fyra lärare i engelska på en högstadieskola. Intervjufrågorna har innefattat allt från hur lärare arbetar med det nationella provet och hur de ser på provet, till hur målen med det nationella provet uppfylls. Resultatet av undersökningen är att det nationella provet underlättar lärarnas arbete. Lärarna anser även att provet fungerar som ett bra stöd då de ska betygsätta eleverna. Dock visar denna undersökning att förberedelserna till det nationella provet främst gagnar svagare elever.The purpose of this dissertation is to investigate how teachers perceive and work with the national tests in order to help students meet the goals of the course. Furthermore, due to our future careers as teachers, we want to gain more insight into the role national tests play in English. This is a qualitative study based on formal in-depth interviews that can provide a good understanding of the subject and of the informants’ views. As the teachers at secondary school work with national tests yearly they were best suited as interviewees in this investigation. Four interviews were carried out with teachers and they lasted approximately 40 minutes each.The interviews touched on a variety of questions ranging from how the teachers work with the national test and how they look upon the test, to how the purposes stipulated by Skolverket regarding the national test are fulfilled. The outcome of the interviews is that the national test in general facilitates more than complicates teachers’ work. The test serves as a good support when assessing and grading the students since it can confirm the teachers’ assessment of the students’ capability. However, this study also shows that the preparation methods used before the national test benefit weaker learners more than stronger ones.

Full textAbstract:
Aujourd'hui, les technologies de captation et de restitution sonore se développent dans le but de diffuser des scènes avec un rendu spatialisé. Avant leur diffusion, les extraits sonores peuvent être évalués en terme de qualité par des méthodes recommandées par I'Union lnternationale des Télécommunications (évaluation des codecs de compression, procédés de prise ou restitution sonore...). Cependant, ces standards d'évaluation montrent certaines faiblesses notamment en ce qui concerne les attributs de qualité à évaluer. La dimension spatiale n'est pas prise en compte spécifiquement. Dans ce travail, une méthodologie dédiée à l'évaluation de la qualité de I'audio spatialisé est mise en place notamment pour répondre aux biais identifiés. De par l'utilisation d'une catégorisation libre et d'une analyse multidimensionnelle, vingt-huit attributs ont été catégorisés en trois familles d'attributs : le Timbre, l'Espace et les Défauts. Ces trois attributs généraux ont été inclus dans un test d'écoute. Celui-ci se déroule en deux phases : l'évaluation de la qualité globale suivie de l'évaluation des trois attributs simultanément sur une même interface. Les tests sont réalisés sans référence explicite, le fichier original constitue une référence cachée. De plus, trois signaux audio, dit ancrages, spécifiques à chacun des trois attributs ont été définis puis superposés pour définir un ancrage unique triplement dégradé. La méthode a été testée à la fois sur un système de restitution au casque avec des contenus binauraux mais également sur un système multicanal 5.1. L'évaluation de stimuli de qualité intermédiaire est préconisée ainsi que des contenus présentant un effet spatial prononcé. L'évaluation multicritère a montré son intérêt dans certaines conditions et permet ainsi d'identifier les caractéristiques qui sont dégradées. Les attributs Défauts et Timbre ont montré un poids influant sur la qualité globale tandis que le poids de I'attribut Espace est plus discutableNowadays, recording and restitution technologies focus on a spatial rendering of sound. Before their broadcast, the quality evaluation of sound excerpts is often necessary. Methods recommended by the international telecommunication union denote some weaknesses about sound attributes to be evaluated.For example, spatial dimension is barely taken into account. A methodology dedicated to the assessment of spatial audio quality is proposed in order to avoid some biases. With a free categorization and a multidimensional scaling, 28 attributes were clustered in three families '. Timbre, Space and Defecfs. These three categories were included in a listening test split into two sessions : first, the assessment of overall quality and then, the evaluation of the three categories presented simultaneously on a same interface.Tests were conducted without explicit reference, but, the original version was considered as a hidden reference. Moreover, three specific anchors, each one associated to dedicated categories, were defined and then were mixed to define a unique anchor impaired in three ways. The method was tested on a 5.1 system and on binaural contents with headphone restitution. lntermediate quality of contents is recommended as well as contents with relevant spatial effects. The interest of a multicriteria assessment is to identify which properties of sound are impaired. Linear regression shows that Defecfs and Timbre attributes have influential weight on overall quality while the weight of Space attribute is more dubious

Full textAbstract:
Thesis (MAud)--University of Stellenbosch, 2011.ENGLISH ABSTRACT: Speech audiometry for diagnostic purposes is widely used by audiologists around the world, but its application is starting to shift more towards rehabilitative purposes for people with hearing impairment. This has created the need for the development of appropriate test materials, including speech-in-noise tests, in the first language of the person undergoing rehabilitation. This document describes a study entailing the first phase in the development of an Afrikaans sentence perception test in noise based on the City University of New York (CUNY) topic-related sentences (Boothroyd, Hanin & Hnath, 1985). The test is called Sinslyste in Afrikaans vir Volwassenes in Lawaai [Sentence lists in Afrikaans for Adults in Noise] (SAV-L). Twenty-seven sentence lists containing 12 sentences each were compiled and evaluated by eight speakers of Afrikaans for their naturalness before they were recorded together with three-talker babble as masking noise. The recorded material was then presented to six groups of ten participants each (with the exception of nine participants in one of the rounds) and adjusted in intensity to improve inter-list reliability. Two scorers were used at intervals to determine inter-rater reliability. Test conditions were also replicated after an interval of six months or more to establish test-retest reliability. In a last round of testing, the test was administered at the intended presentation level to assess the appropriateness of the chosen level. Through adjustment of list intensities, inter-list reliability was improved to a 13.87% variance between list scores. Test-retest reliability showed a bias with an intra-class correlation agreement of 0.859. This was thought to be due to participants’ improved familiarity with the clinical environment over time, however longer term measures of test-retest reliability remains to be done. Inter-rater reliability was very high with an intra-class agreement of 0.999. The intended test level of 50dBHL with a signal-to-noise (SNR) ratio of +5dB, was found to be an acceptable fixed SNR. The test can be used in its current form for assessment of amplification candidacy as well as monitoring of progress during rehabilitation. Further research is indicated for the establishment of the sensitivity of the test. It is concluded that just as a clinician is expected to select the most suitable diagnostic test based on the patient’s history, signs and symptoms, so should the audiologist be expected to select the most appropriate rehabilitative measure based on the patient’s communication needs and established treatment goals. The SAV-L is a valuable contribution to the pool of speech perception tests available as rehabilitative measures, and is specifically suitable for adults with well-developed spoken language.
AFRIKAANSE OPSOMMING: Spraakoudiometrie vir diagnostiese doeleindes word algemeen gebruik deur oudioloë regoor die wêreld, maar die toepassing daarvan is besig om te skuif na rehabilitasie van mense met gehoorgestremdheid. Die behoefte vir die ontwikkeling van geskikte toetsmateriaal, insluitend spraak-in-geraastoetse, in die eerste taal van die persoon wat rehabilitasie ondergaan, het dus begin ontwikkel. Hierdie dokument beskryf ‘n studie wat die eerste fase van die ontwikkeling van a Afrikaanse spraakpersepsietoets in geraas behels. Dit is gebaseer op die City University of New York (CUNY) onderwerp-verwante sinne (Boothroyd, Hanin & Hnath, 1985). Die ontwikkelde toets is benoem Sinslyste in Afrikaans vir Volwassenes in Lawaai (SAV-L). Sewe-en-twintig sinslyste met twaalf sinne per lys is saamgestel en geëvalueer deur ag Afrikaans-sprekende persone om hulle natuurlikheid te bepaal voordat dit opgeneem is tesame met drie-spreker babbel as maskeringsgeraas. Die opgeneemde materiaal is aan ses groepe van tien deelnemers elk aangebied (met die uitsondering van slegs nege deelnemers in een van die rondtes) en aangepas in intensiteit om inter-lys betroubaarheid to verbeter. Twee tellers is van tyd tot tyd gebruik om inter-beoordelaar betroubaarheid te bepaal. Toetskondisies was ook ná ‘n periode van ses maande gereplikeer om toets-hertoets betroubaarheid to bepaal. In ‘n laaste rondte van toetsing was die toets geadministreer teen die beoogde toetsvlak om die geskiktheid van hierdie toetsvlak te bepaal. Inter-lys betroubaarheid is verbeter na ‘n 13.87% variase tussen sinslystellings deur die aanpassing van die intensiteite van die lyste. Toets-hertoets betroubaarheid het ‘n voorkeur met ‘n intra-klas korrelasie ooreenstemming van 0.859 getoon. Hierdie voorkeur was vermoedelik weens die deelnemers se toenemende bekendheid met die kliniese omgewing, alhoewel langer termyn metings nog gedoen moet word om hierdie tendens verder te ondersoek. Inter-beoordelaar betroubaarheid was goed met ‘n intra-klas korrelasie van 0.999. Die beoogde toetsvlak van 50dBGP met ‘n sein-tot-ruis ratio van +5dB is as ‘n geskikte ratio bevind. Die huidige vorm van die toets kan gebruik word vir die evaluasie van kandidaatskap van klankversterking sowel as monitering van vordering tydens rehabilitasie. Verdere navorsing is aangedui vir die bepaling van die toets se sensitiwiteit. Daar is afgelei dat net soos daar van ‘n klinikus verwag word om die mees geskikte diagnostiese toets te kies gebaseer op die pasiënt se geskiedenis, tekens en simptome, net so moet daar van die die oudioloog verwag word om die mees geskikte rehabilitasiemeting te selekteer, gebaseer op die pasiënt se kommunikasiebehoeftes en vasgestelde behandelingsdoelwitte. Die SAV-L is ‘n waardevolle hulpmiddel in die versameling spraakpersepsietoetse wat beskikbaar is vir rehabilitasiemetings en is spesifiek geskik vir volwassenes met goed-ontwikkelde gesproke taal.

Full textAbstract:
This thesis proposes a test method for evaluating the perceived vibration which occurs at the driver's hand in automotive steering wheel interface. The objective of the research was to develop frequency weightings for quantifying the human perception of steering wheel hand-arm vibration. Family of frequency weightings were developed from equal sensation curves obtained from the psychophysical laboratory experimental tests. The previous literature suggests that the only internationally standardised frequency weighting Wh is not accurate to predict human perception of steering wheel hand-arm vibration (Amman et. al, 2005) because Wh was developed originally for health effects, not for the human perception. In addition, most of the data in hand-arm vibration are based upon responses from male subjects (Neely and Burström, 2006) and previous studies based only on sinusoidal stimuli. Further, it has been continuously suggested by researchers (Gnanasekarna et al., 2006; Morioka and Griffin, 2006; Ajovalasit and Giacomin, 2009) that only one weighting is not optimal to estimate the human perception at all vibrational magnitudes. In order to address these problems, the investigation of the effect of gender, body mass and the signal type on the equal sensation curves has been performed by means of psychophysical laboratory experimental tests. The test participants were seated on a steering wheel simulator which consists of a rigid frame, a rigid steering wheel, an automobile seat, an electrodynamic shaker unit, a power amplifier and a signal generator. The category-ratio Borg CR10 scale procedure was used to quantify the perceived vibration intensity. A same test protocol was used for each test and for each test subject. The first experiment was conducted to investigate the effect of gender using sinusoidal vibration with 40 test participants (20 males and 20 females). The results suggested that the male participants provided generally lower subjective ratings than the female participants. The second experiment was conducted using band-limited random vibration to investigate the effect of signal type between sinusoidal and band-limited random vibration with 30 test participants (15 males and 15 females). The results suggested that the equal sensation curves obtained using random vibration were generally steeper and deeper in the shape of the curves than those obtained using sinusoidal vibration. These differences may be due to the characteristics of random vibration which produce generally higher crest factors than sinusoidal vibration. The third experiment was conducted to investigate the effect of physical body mass with 40 test participants (20 light and 20 heavy participants) using sinusoidal vibration. The results suggested that the light participants produced generally higher subjective ratings than the heavy participants. From the results it can be suggested that the equal sensation curves for steering wheel rotational vibration differ mainly due to differences of body size rather than differences of gender. The final experiments was conducted using real road signals to quantify the human subjective response to representative driving condition and to use the results to define the selection method for choosing the adequate frequency weightings for the road signals by means of correlation analysis. The final experiment was performed with 40 test participants (20 light and 20 heavy participants) using 21 real road signals obtained from the road tests. From the results the hypothesis was established that different amplitude groups may require different frequency weightings. Three amplitude groups were defined and the frequency weightings were selected for each amplitude group. The following findings can be drawn from the research: • the equal sensation curves suggest a nonlinear dependency on both the frequency and the amplitude. • the subjective responses obtained from band-limited random stimuli were steeper and the deeper in the shape of the equal sensation curves than those obtained using sinusoidal vibration stimuli. • females provided higher perceived intensity values than the males for the same physical stimulus at most frequencies. • light test participants provided higher perceived intensity than the heavy test participants for the same physical stimulus at most frequencies. • the equal sensation curves for steering wheel rotational vibration differ mainly due to differences in body size, rather than differences of gender. • at least three frequency weightings may be necessary to estimate the subjective intensity for road surface stimuli.

Bien que le Rorschach soit aujourd’hui l’un des tests psychologiques les plus utilisés et étudiés, la compréhension des qualités du stimulus du test et leur influence sur les réponses, reste toujours incomplète. Partant d’une approche perceptivo-cognitive au Rorschach, l’objectif de cette recherche consiste à étudier des caractéristiques des planches qui composent ce test et à analyser la manière dont les propriétés distales de la planche influencent les éléments structuraux de la réponse. La recherche est composée de trois études. Dans la première étude, nous analysons l’influence de la planche par l’analyse des données normatives issues d’un échantillon non-consultants français (n = 247). Notre deuxième étude vise à examiner l’influence de la propriété distale de la couleur chromatique sur les réponses. Nous avons mené, dans ce but, une expérimentation avec une série achromatique des planches de Rorschach, identiques aux planches originales à l’exception de l’absence de la couleur. Cette série a été administrée aux 37 sujets adultes non-consultants par la méthode du système intégré. Dans la troisième étude, nous avons analysé une catégorie spécifique de réponses au Rorschach, les réponses visage, en montrant l’apport possible de différents domaines de la psychologie, et en particulier de la recherche sur la perception. Les résultats de ces trois études sont discutés en référence à la compréhension du processus de la réponse au Rorschach, et en soulignant la dialectique entre les facteurs émanant du stimulus et des facteurs personnels du sujet. De plus, les implications sur la manière dont la spécificité des planches pourrait être prise en compte sont proposéesAlthough the Rorschach test is one of the most widely used and studied psychological tests, our understanding of the qualities of the stimulus of the test and their influence on the responses, rests incomplete. Emanating from a perceptual cognitive approach to the Rorschach, the objective of this research is to study the characteristics of the Rorschach cards, and to analyze how their properties affect the structural elements of the response. Our research consists of three studies. In the first study we analyze the influence of the cards by analyzing normative data from a French non-patients sample (n = 247). The second study examines the influence of the chromatic color on the responses. To this end, we conducted an experiment with an achromatic version of the cards, which are identical to the original ones with the exception of the lack of color. These cards were administered in the standardized way of the Comprehensive System to 37 non-patient participants. In the third study we analyze a specific category of Rorschach responses, namely face responses, showing the relevance of different fields of psychology, and in particular research in perception. The results of the three studies are discussed in reference to the response process, while emphasizing the interplay between the features of the stimulus and the personality of the subject. In addition, suggestions are made as how to use knowledge on the cards to improve the diagnostic power of the test

This study examined the psychometric properties for the Draw-A-Person (DAP) test (Naglieri, 1988). Data were collected from 191 children following the accepted procedure from an earlier study (Badger & Jones, 1988). Drawings were scored using both Harris' (1963) and Naglieri's (1988) scoring systems following the procedures outlined in the manuals. Basically, the DAP test demonstrated reliable and valid properties. The Naglieri's (1988) scoring system was favored in this study because it demonstrated more consistent internal consistency, higher inter- and intra-rater reliability and satisfactory construct validity. Positive and moderate high correlations with the scores obtained from Goodenough-Harris's scoring systems supported that the Naglieri's version measured the same concept as the old system. Psychometric properties of the DAP test support use in clinical and research settings to gather data from children about their general abilities.

Full textAbstract:
A technique commonly used to study the structure of memory entails preceding a task by a brief masked presentation of a potentially relevant stimulus. In two experiments, I examined the type of facilitation obtained on a picture fragment completion task by prior presentation of either the name of the completed object, a complete picture of the object, or the fragment itself. In Experiment 1a significantly more ambiguous picture fragments (i.e. fragments supporting a number of interpretations) were identified after exposure to pictures than to picture names or picture fragments. Experiment 1b verified that the information in the masked primes was not available to conscious awareness. These results suggest that under limited encoding conditions only bottom-up activation provided by prior presentation of the fragments aids shape recognition under degraded conditions. Implications for the structures and processes involved in shape recognition are discussed.

Full textAbstract:
Faces are highly complex visual stimuli that playa disproportionate role in social interactions. Based on visual information from faces alone, humans can judge an individual's race, gender, age, identity, mood and intentions. The first aim of this thesis is to investigate aspects of the mechanisms that underlie the extraordinary sensitivity of human face perception. In the first study, sensitivity to various face features was quantified. Evidence was found of enhanced sensitivity to external (head-shape, hairline), relative to internal (nose, mouth, eyes, eyebrows) features, with the lowest sensitivity for features most affected by face dynamics. Discrimination thresholds were significantly higher when features were embedded within an average face context, relative to isolated presentation. Although inversion significantly reduced sensitivity, the external feature advantage remained. These results have implications on the nature of holistic processing mechanisms for unfamiliar faces. In a different study, face perception was investigated in peripheral vision. Discrimination thresholds for full-faces, internal features and external features were lower in the left visual field, relative to all other visual field locations, consistent with the cortical lateralisation of the face-sensitive fusiform face area. Sensitivity to headshapes, on the other hand, was greatest in the lower visual field. This is consistent with the premise of non-overlapping processing mechanisms for the general shape of objects and specific object categories, such as faces. The aim of a further study was to investigate the neuronal representation of faces by determining the effect of adaptation on face discrimination. Face adaptation significantly reduced unfamiliar face discrimination sensitivity. This effect was, however, highly identity-specific; adaptation did not transfer between different face identities. The magnitude of this adaptation effect increased monotonically with adapting face distinctiveness (how much an individual face differs from an average/mean face), but only up to a limit. These results suggest that individual face identities are encoded by discrete neuronal populations that respond with increasing magnitude as faces become progressively more different from an average face but exclude more extreme face caricatures. Based on these results, the final part of this thesis outlined the development of a new clinical test of face perception. This new test is designed to overcome the limitations of existing face tests such as restricted testing ranges and confounding factors (e.g. memory, familiarity). The range of normal face sensitivity was determined in a large group of young adults. Older adults showed preserved face discrimination sensitivity. A case study of a patient with suspected developmental prosopagnosia demonstrates that the test has the potential to accurately identify impairments of face perception enjoying a substantially higher sensitivity than standard face tests.

Lim, Phui Cheng. "Cross-cultural effects on drivers' hazard perception : validating a test paradigm for developing countries." Thesis, University of Nottingham, 2017. http://eprints.nottingham.ac.uk/39867/.
Full textAbstract:
The hazard perception skill of a driver refers to their ability to identify potentially dangerous events on the road, and is one of the only driving-specific skills that has been consistently linked to accident rates. Hazard perception tests are used in several developed countries as part of the driver licensing curriculum, however little research has been done in developing countries where road safety is a primary concern. The extent to which hazard perception skill transfers to different driving environments is also unclear. This thesis therefore has two major aims: to examine hazard perception in a cross-cultural context, and to validate a hazard perception test for potential use in driver licensing in lower-income, developing countries. Most of the experiments in this thesis compare hazard perception skill in drivers from the UK – where hazard perception testing is well established – and drivers from Malaysia – a developing country with a high accident rate where hazards frequently occur. Typically, hazard perception skill is assessed by showing participants clips filmed on the road and asking them to respond as soon as they detect a developing hazard, with shorter response times reflecting greater levels of skill. Chapter 2 presents evidence that Malaysian drivers may be desensitized to hazardous road situations and thus have increased response times to hazards, creating validity issues with the typical paradigm. Subsequent chapters therefore use a predictive paradigm called the “What Happens Next?” test that requires drivers to predict hazards, leaving performance unaffected by hazard desensitization. Malaysian drivers predicted hazards less accurately than UK drivers in all cross-cultural experiments, indicating that exposure to a greater number of hazards on Malaysian roads did not have a positive effect on participants’ predictive hazard perception skill. Further experiments indicated that explicit knowledge plays a minor role in the “What Happens Next?” test, and that experienced drivers appear to compensate for reduced visual information more effectively than novices. Experienced drivers from both Malaysia and the UK also outscored novices in all experiments using the predictive paradigm, suggesting the “What Happens Next?” test provides a valid measure of hazard perception skill and may offer a practical alternative for hazard perception testing in developing and even developed countries.

Full textAbstract:
Auditory short-term memory (STM) is important for speech and language development and for learning new information presented auditorily. Research has shown that auditory STM ability is of a developmental nature in the 5 through 8 year age range for a variety of auditory stimuli. Many tests and subtests are available to measure auditory STM ability, however one test, the Auditory Memory Test Battery (AMTB) measures auditory memory span and memory for sequence for 5 types of stimuli.
The purpose of this study was to collect normative data on the AMTB scores of normal 9 through 13 year old students and young adults ages 20 through 30 years. The main experimental question was: What are the means and standard deviations of the AMTB scores from samples of normal children 9 through 13 years of age and normal young adults 20 through 30 years of age. A secondary question was: Are the differences between the performance scores statistically significant?

Les prises en charge de ce symptôme, focalisées sur les soins fondamentaux de la toilette, sont souvent une gageure et échouent. En nous inscrivant dans une démarche pluridisciplinaire, nous tentons de donner du sens aux odeurs corporelles dans la schizophrénie. Notre hypothèse est que les comportements d’hygiène personnelle pourraient être conditionnés par les capacités du système olfactif des patients, sujet tout juste effleuré jusqu’ici. Une épreuve d’identification d’échantillons odorants au moyen d’images photographiques des sources d’odeurs potentielles a été normalisée : le test olfacto-visuel (TOV). L’application du TOV a permis de montrer un défaut des capacités d’identification olfactive chez les patients, sa relation avec la symptomatologie et les compétences sociales des patients. La mise en place d’un atelier thérapeutique à médiation olfactive a conduit à montrer les conséquences bénéfiques de la prise en charge de la sensorialité olfactive sur l’évolution des capacités olfactives, la symptomatologie, les comportements hygiéniques et alimentaires ainsi que sur le vécu affectif des patients atteints de schizophrénie. Ces derniers montrent aussi des dysfonctionnements de la sphère émotionnelle. Nous avons d’abord réanalysé les liens existants entre la caractéristique hédonique des odorants et les émotions dans la population générale, puis repoussé leurs simplifications habituelles. Les liens entre odeurs perçues et émotions évoquées par les échantillons odorants apparaissent perturbés chez les patients. Ce travail de recherche propose une relecture de la perception olfactive dans la schizophrénie et montre l’intérêt thérapeutique de son exploitation. L’évolution clinique positive des comportements d’hygiène personnelle, après la prise en charge olfactive, valide l’hypothèse du rôle de l’odeur corporelle en tant que gardien de l’existence. L’ « être-au-monde odorant » des patients possède une fonction identitaire dans la schizophrénieIn the case of schizophrenia, numerous patients have poor personal hygiene, which is typical of negative symptomatology. This self-neglect engenders offensive body odor which also was in the past a crucial element for the diagnosis. Attempts to address the manifestations of that symptom by focusing on the principles of basic grooming often prove a losing battle and fail. Thanks to an interdisciplinary approach, our endeavor is to try and give meaning to body odor for schizophrenics. Our hypothesis is that personal hygiene behavior could be conditioned by the patients’ olfactory system capacities – a domain which has barely been studied to this day. An olfactory stimuli identification test of potential odor sources via photographic images has been standardized: the olfacto-visual test (OVT). The OVT’s application has permitted to reveal an olfactory identification deficit in the patients, its relation to symptomatology and the patients’ social skills. The setting up of a therapeutic workshop through olfactory mediation has led to show the beneficial consequences of the caring for the sense of smell on the evolution of olfactory skills, symptomatology, hygiene and dietary patterns, as well as on the patients’ emotional life. Patients suffering from schizophrenia also present emotion-management troubles. We have first analyzed the existing links between the hedonic characteristics of odorants and the emotions among the general population anew, and then questioned the usual simplifications about them. The links between perceived odors and emotions produced by the odor samples appeared as blurred for the patients. This research offers a new approach of the olfactory perception in schizophrenia and shows the therapeutic interest of its exploitation. The positive clinical evolution of personal hygiene behavior after the olfactory caring confirms the hypothesis of the role of body odor as a token of existence. The patients’ bad body odor reveals an identity function in schizophrenia

Full textAbstract:
A multivariate model of health self-perceptions was postulated based upon a comprehensive set of health related variables suggested by previous bivariate research. Components of the model included measures of health attitudes, health practices, health locus of control, a measure of stress/ coping, and a physical health measure.
A stratified random sampling technique was used to select 10 8 subjects based upon the external measure of physical health which included categories ranging from disability-severe to symptom free-high energy level. All subjects completed a health questionnaire comprised of measures of the model components, two measures of health self-perceptions, and the Health Resource Task, an author designed instrument measuring a subject's ability to generate flexible health alternatives/resources. Bivariate correlational analysis revealed that the physical health, stress/coping, health practices, and locus of control measures and certain of the health attitude subscales were significantly correlated to general health self-ratings. A multivariate model including these variables accounted for almost 50 percent of the variance in one of the general health self-ratings measures and approximately 38 percent of the variance in the Health Resource Task. Suggestions for refining the proposed model were made.

Full textAbstract:
This paper examined the effects of distance priming on test anxiety and judgment. Research suggests that individuals’ perceived distance can impact their affect and judgments, which sheds light on the principle of “distance equals safety” (Williams & Bargh, 2008). Taking an exam invokes both cognitive and emotional anxiety, such as worry, panic, and tension. It is hypothesized that the distance priming may reduce test anxiety—particularly, the emotionality aspect—as well as perceived test difficulty. The results showed that, counter to the hypotheses, there was no significant difference among the three priming groups in their emotional test anxiety or perceived test difficulty. There is a significant correlation between ACT score and cognitive test anxiety, supporting past literature that as one’s intellectual ability increases, their cognitive test anxiety decreases. Further research needs to be conducted to replicate the efficacy of the priming method by Williams and Bargh (2008) and to use more effective ways of provoking performance anxiety.

Full textAbstract:
La plupart des méthodes projectives (Didier ANZIEU, Catherine CHABERT, 1961) ont comme support de travail la vue. Le processus haptique est-il suffisamment discriminatif pour valider la fiabilité de ce test sous ce mode ? Un étalonnage différencié respecte-t-il la valeur donnée à ce test par H. Rorschach ? Le sujet, en perdant la vue, va devoir mobiliser ou trouver des nouvelles ressources physiques et psychiques pour devenir autonome et poursuivre sa vie. Tout en lui est effracté : sa construction narcissique, sa représentation du monde et son altérité dans le regard de l’autre. Le Rorschach permet d’aborder la richesse psychique d’un sujet. Il nous donne à voir les potentialités psychiques du sujet dans sa relation à lui-même et aux autres. Or, il fait appel à une activité visuelle qui organise un matériel informel. C’est une activité imageante qui fait passer du perceptif au projectif, du perçu au vécu…Le toucher, dans certaines situations, peut être un relais de perception, de projection et donner à voir les représentations du sujet. Cette recherche peut permettre d’envisager une autre manière d’étalonner ce test afin de pouvoir le quantifier, le qualifier en changeant par exemple l’item « couleur » par l’item texture…Dans cette étude, il nous faut vérifier que cela n’enlève pas la valeur que donnait H. Rorschach à ce test, à cet item mais au contraire l’ouvre à une autre dimension clinique, celle d’une clinique spécifique du sujet mal ou non-voyant. En respectant un protocole spécifique, une telle passation permettrait une médiation pour le sujet en situation de handicap visuel vers une « meilleure » ré-élaboration de son projet de vie. Par ailleurs, cette étude pourrait ouvrir d’autres approches sur le dessin en relief et permettre notamment à toute une partie de la population vieillissante d’utiliser cette modalité dans la vie quotidienne, pour de nouveaux repèresThis research follows a study already begun in Master 1; it deals with the haptic process adapted to 3-dimensional Rorschach-plates. Is the haptic process sufficiently discriminating to validate the reliability of this test under this mode ? Does differentiated calibration respect the values given to this test by H. Rorschach ? After loss of sight, a subject is going to have to mobilize or find new physical and psychic resources to become autonomous and go on living. Everything in that person is broken: their narcissistic construction, their representation of the world and their differences in the eye of others. The Rorschach test allows us to approach a subject’s psychic wealth. It shows us the psychic potential of a subject in relation to himself and to others. Yet the Rorschach test calls on visual activity to organize an informal material. It is an activity based on images which leads one from the perceptive to the projective, from perceived to experienced. In certain situations, touch can be an intermediary for perception, for projection and can show how the subject is represented. Through this research, we can consider calibrating this test in another way in order to measure quantity and quality by changing “colour” for ‘texture’, for example. In this study, it is essential to verify that this does not remove the value given by H. Rorschach to this item in this test, but on the contrary opens it to other clinical dimensions, that specific of the blind or partially-sighted.Moreover, this study could open up new approaches to 3-dimensional drawings and allow a great part of the ageing population to use this method in daily life, to find new bearings. For instance, using certain textures to find one’s way around the flat by 3-dimensional pictograms

Full textAbstract:
Objective: The purpose of this current study was to develop an audiovisual speech perception test for New Zealand English (NZE) speaking children by adapting the American version of the Children’s-Build-A-Sentence (Ch-BAS) test. Three hypotheses were formulated for this study. First, it was predicted that the New Zealand version of the Ch-BAS test would show list equivalency. A second hypothesis was that all children would perform significantly better on the auditory-visual (AV) condition of the test in comparison to the vision-only (V-only condition). A third hypothesis was that older children would perform significantly better than younger children on both test conditions.
Design: The American version of the Children’s-Build-A-Sentence test was adapted for use with NZ children and an audiovisual recording was made of an adult NZE speaker saying the sentence stimuli. This was then edited into a picture response matrix format to make up the NZ Ch-BAS test which is comprised of three lists made up of mono, bi, and tri-syllabic words. Equal numbers of sentences were allocated to the three test conditions: auditory-only (A-only), V-only, and AV conditions. The NZ Ch-BAS test was then administered to 30 normal hearing (NH) NZE-speaking children aged between 7-11 years with equal numbers (n=6) in each age group. All testing was conducted in the presence of multi-talker babble noise, set individually for each child to obtain approximately equivalent performance for the A-only condition.
Results: Results revealed that the NZ Ch-BAS test lists were equivalent for both the V-only and AV test conditions when testing NH children. A significant age effect was also found, where older children showed superior speech reading performance in comparison to younger children. A stronger age effect was seen for the V-only condition in comparison to the AV condition. All children performed significantly better on the AV condition in comparison to the V-only condition.
Conclusions: The three Ch-BAS test lists demonstrate list equivalency and therefore can be used to develop a reliable test for NZ-English speaking children. As anticipated, there was an age effect in regard to speech reading performance; however this effect was only found for the V-only condition. All children performed significantly better on the AV condition in comparison to the V-only condition. A number of possible explanations for superior performance are provided and clinical uses for the NZ Ch-BAS test are discussed.

Full textAbstract:
Prior research suggests that creativity is a trait women find attractive in potential male romantic partners. This study applied Fisher's theory of runaway sexual selection to creativity. Fisher's theory predicts that when a trait with no apparent adaptive advantage is found sexually attractive, both prevalence of and preference for the trait should increase over evolutionary time. This study hypothesized that creative performance and creative partner preference would be correlated, as predicted by this theory. It was believed that perception of creativity would be necessary if individuals are to successfully identify it in partners, which would then allow for the runaway chain of events identified by Fisher to occur. Creative self-perception was hypothesized to correlate with the creative performance and creative partner preference as well. Study participants (198 heterosexual undergraduate females) were given measures of the three constructs of interest and general intelligence was also assessed. Results supported Fisher's runaway sexual selection theory and the hypothesized relationship between creative performance, creative partner preference, and creative self-perception. This study found that women high in creativity were also more likely to prefer that potential partners be higher in creativity and were also more likely to perceive themselves as creative. Previous findings that creative performance and intelligence are related were also supported. Implications of these findings and future research directions are discussed.

Full textAbstract:
Sensitivity to differential motion components, shearing and compressive (opposed) motion, was examined. The hypothesis that the visual system contains local mechanisms specifically sensitive to these types of motion was tested. Stimuli consisted of two moving sinusoidal gratings. Sensitivity to shear and compression was compared with sensitivity for linear motion. Lower thresholds of motion and contrast sensitivities were obtained. Subjects were more sensitive to opposed than to non-opposed motion for a range of grating orientations and different grating spatial frequencies. However sensitivity for opposed motion decreased in the presence of a second added linear motion. The hypothesis of local shear and compression mechanisms was rejected in favour of antagonistic (opponent) interactions between local motion mechanisms. Motion capture was examined. Stimuli were made up of a circular test grating surrounded by another grating. Subjects were required to judge the direction of motion of the test grating. Experiments examined the effects on motion capture of: centre grating size; orientation of surround; relative contrast of centre and surround; plaids in the surround. Conditions favouring motion capture were: with the smallest centre grating; with surround and centre orientations within thirty degrees; with surround had higher contrast than the centre; and only when a plaid surround contained a component of similar orientation as the centre. For conditions of motion capture relative to those of no-capture, increased velocity thresholds for judging the centre direction were found. This was associated with a shift in the bias point between opposed directions with no change in overall sensitivity to motion. It is suggested that a cooperative network of local motion mechanisms featuring centre-surround opponency can account for all the results of this study.

L'attente qui apparaît la plus réaliste à entretenir pour cinq ateliers praxéologiques centrés sur le test personnel d'efficacité est de percevoir un début modeste de décristallisation d'une représentation de la compétence uniquement soutenue par le paradigme d'expert et ce, chez deux intervenantes seulement. Cette amorce de mouvement est caractérisée par une diminution de leurs attentes envers elles-mêmes en termes de performance ainsi qu'une plus grande tolérance au fait de se percevoir dans l'erreur. Elles gèrent ainsi mieux leur expérience personnelle dans le cadre d'une intervention, ce qui semble accroître leur capacité d'autorégulation. Chez d'autres, l'impact semble plus lié au développement d'une compétence personnelle que professionnelle. Cet impact a été observé alors que le contexte de la recherche n'était pas idéal : groupe non-homogène, animateur junior et nombre de séances restreint.

Full textAbstract:
This thesis reviews progress toward an understanding of the processes involved in the solution of spatial problems. Previous work employing factor analysis and information processing analysis is reviewed and the emphasis on variations in speed and accuracy as the major contributers to individual differences is noted. It is argued that the strategy used by individuals is a preferable explanatory concept for identifying the cognitive substratum necessary for problem solving.
Using the protocols obtained from subjects solving The Minnesota Paper Form Board (Revised), a test commonly regarded as measuring skill in spatial visualization, a number of different strategies are isolated. Assumptions as to the task variants which undergird these strategies are made and tested experimentally. The results suggest that task variants such as the size of the stimulus and the shape of the pieces interact with subject variables to produce the operating strategy. Skill in problem solving is revealed in the ability to structure the array, to hold a structured image and to reduce the number of answers requiring intensive processing. The interaction between task and subject variables results in appropriate or inappropriate strategies which in turn affect speed and accuracy.
Results suggest that strategy formation and usage are the keys to explaining individual differences and an heuristic model is presented to explain the performance of individual subjects on the problems involved in the Minnesota Paper Form Board. The model can be used to predict performance on other tests; and as an aid to teaching subjects experiencing difficulties.
The model presented incorporates strategy variation and is consequently mores complex than previously suggested models. It is argued that such complexity is necessary to explain the nature of a subject's performance and is also necessary to perform diagnostic evaluation.
Certain structural -features of the Minnesota Paper Form Board are questioned and suggestions for improvement included. The essential explanatory function of the strategy in use makes the prevalent group administration approach suspect in the prediction of future performance in spatial or vocational activity.

Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. New timber building systems have been developed and increasedbearing capacity of floors has made it possible to build with longer spans. Thelow mass of timber floors makes them more sensitive to dynamic loading byhuman activities, such as walking, running and jumping, compared to heavyfloors e.g. concrete floors. To improve vibration performance it is possible tochange the structural properties of the floors by increasing mass, stiffness ordamping properties. The most practicable solution is to increase the stiffness.Improved damping is also highly effective, but is difficult estimate and designaccurately since it originates from many sources in the finished building. In thepresent thesis the effects on dynamic properties from increased stiffnesstransverse to the load bearing direction of a floor have been assessed from testsin laboratory. The effect on dynamic performance of a timber floor fromelastic/damping interlayers (polyurethane elastomers) installed in the junctionsbetween walls and floors have been assessed in laboratory and in situ. Also thechange in dynamic properties of an in situ floor has been investigated atdifferent stages of construction and compared with results from laboratory tests.The present criteria for design of timber floors with respect to vibrationperformance were developed at a time when timber floors were mainly used insingle-family housing. The traditional timber joist floors differ in structuralbehaviour from the new types of floors developed recently. The experiencedvibration annoyance by residents in single- and multifamily housing differs asthe source of vibration disturbance and those who become disturbed aredifferent. The changed conditions give cause for a review of present designcriteria. A laboratory and field study on vibration performance was conductedwith questionnaires and dynamic performance measurements. The subjectiveand objective results were correlated and indicators for vibration acceptabilityand annoyance were assessed and new vibration performance criteria andvibration performance classes were suggested.

ABSTRACT The goal of this qualitative study was to gain an understanding of the perception that exists for fourteen Jamaican instructional leaders as they integrate Tablet Computers (TCs) into the pedagogical process to prepare grade four students for the Grade Four Literacy Test (G4LT). The research was conducted in four schools; three rural primary schools in the parishes of Trelawny, Manchester and St Elizabeth and an urban primary school in Kingston. The focal group comprised four principals, three vice principals, three grade four coordinators and four grade four teachers from the scope of schools that were piloting the Tablet in School (TIS) initiative. Structured interviews and observation were used as data sources. Findings from the data revealed that the instructional leaders, while receptive to the initiative of utilizing the TCs in the pedagogical process, were unable to speak to how effective its usage was in preparing students for the G4LT. Furthermore, although the devices were somewhat facilitated in the teaching and learning process, the majority of instructional leaders did not use them to teach the components of the examination. Finally, results suggested that the usage of the TC as an instructional tool had encouraged more favourable responses from students in the classroom learning environment. As the first study to investigate the integration of TC to teach literacy in the Jamaican Primary Classroom, the current study provided novel insights and a springboard for more qualitative investigations into this particular phenomenon. It is also anticipated that the emerging data will influence and inform decision making within the Ministry of Education (MoE).

The integration between Information and Communication Technologies (ICT) and the education field has led to the emergence of Learning Management Systems (LMS). Moodle serves as a platform for students to collaborate, access course material and take exams. This thesis investigates Moodle’s testing function using a mixed-method approach. 111 undergraduates responded to a survey relating to Nielsen’s usability attributes learnability, satisfaction and errors. Additionally, five students were interviewed. The qualitative data was thematically analyzed and indicated that students perceived Moodle’s testing function to be simple to use, though inflexible. Also, concerns were raised about the lack of visual hierarchy. Students suggested a more distinguished testing interface, the addition of a scratch-paper function, and automatic saving to prevent being timed out.

OBJETIVO: Caracterizar o perfil de desempenho de crianças normo-ouvintes de sete e oito anos em um teste de triagem de processamento auditivo. MÉTODO: O trabalho é um estudo observacional descritivo. Foram selecionadas 109 crianças de sete anos e 106 crianças de oito anos da rede regular de ensino de Cuiabá-MT portadoras de limiares de audibilidade de até 15 dBNA, ausência de indicativos de distúrbio de processamento auditivo e ausência de alterações fonológicas. As mesmas foram avaliadas por meio de um teste de triagem de processamento auditivo e as pontuações obtidas foram comparadas com a literatura nacional. RESULTADOS: As médias e os desvios-padrões encontrados nos sub-testes Fala Filtrada, Fala no Ruído e Palavras Competitivas na idade de sete anos foram respectivamente 24,4±5,1, 33,4±3,4 e 76,50±9,7 pontos, e na idade de oito anos 24,0±4,8; 34,0±3,0 e 77,5±10,8 pontos. CONCLUSÃO: As pontuações obtidas, não podem ser generalizadas para todas as crianças brasileiras devido à variabilidade regional reforçando a necessidade de estudos com casuísticas maiores e que descrevam o desempenho de crianças de várias faixas etárias e pertencentes a diversas regiões geográficas e condições sociais.PURPOSE: To characterize performance profile of seven and eight years old children listeners through auditory processing screening test. METHODS: This work is a descriptive observacional study. One hundred nine sevenyear- old children and 106 eight-year-old children regularly attending schools and fitting following criteria were recruited: auditory thresholds up to 15dBNA, absence of auditory processing deficit, and absence of phonologic disturbs. Selected children were evaluated through auditory processing screening test. These children\'s scores were compared with others Brazilian studies. RESULTS: Performance averages and standard-deviations for the sub-tests Filtered Words, Auditory Figure Ground and Competitive Words in seven year-old were respectively 24.4±5.1, 33.4±3.4, and 76.50±9.7 points, while eight year-old were respectively 24.0±4.8, 34.0±3.0, and 77.5±10.8 points. CONCLUSION: The scores in the test used cannot be generalized for the Brazilian children. Due to Brazilian regional variability of children\'s performance in the test, larger multi-centric studies, encompassing children of broader geographic regions and social conditions, as well as age range, are necessary.

Full textAbstract:
Media sources, often containing ideal body images, put forth the message of selfimprovement and the need to achieve a thin physique. For some women, striving to achieve an ideal body can lead to increased risk of engaging in disordered eating, anxiety, and an increased fixation toward body or weight stimuli. Previous research examining the relationship between body satisfaction and attention toward body related stimuli has often compared clinical eating disorder and non-clinical samples. However, these findings do not give an accurate picture of how non-clinical samples respond to thin body images. The present study sought to determine if engaging in a downward social comparison would negate the "fixation" or increased attention given to body images.
Female participants from a university in northern California were randomly assigned to one of two experimental conditions: downward or upward social comparison. Participants were asked to view an advertisement of a model, and write based on a
prompt developed to elicit a downward or upward social comparison. Selective attention toward body related stimuli was then assessed through use of a Stroop task, which randomly displayed thin female silhouettes and abstract images. Error rates and reaction times were recorded, with more errors and slower reactions times reflecting increased attention toward the female silhouette.
A hierarchal linear regression found an association for the downward social comparison condition and self-esteem. Longer reaction time toward body images was seen among women who engaged in a downward social comparison and had low levels of self-esteem. Among women with high BMI, less selective attention was observed. Comparisons of the groups on reaction times, error rates, and body image measures are discussed.

Full textAbstract:
Copper in drinking water elicits a persisting bitter, metallic, or astringent taste. Characteristics and perception mechanisms of copper sensation have not been fully understood. Saliva is assumed to influence copper sensations via binding of salivary electrolytes or proteins with copper. The interaction between salivary components and copper is thought to influence sensory perception by affecting volatility of aroma compounds, de-lubricating salivary proteins, and by controlling solubility of copper. A recent study suggested that intensity of copper taste may be dependent on the amount of solubilized copper, which increases at lower pH. This research was performed to identify 1) the temporal sensory characteristics of copper; 2) the effect of pH on perception of copper sensation; 3) the nature of copper-protein interaction and its impact on sensory perception.
The effect of copper on the volatility of aroma compounds and the role of copper-protein interaction in volatile chemistry were investigated using a model mouth system containing artificial saliva at different pH levels. Headspace concentration of each volatile was measured using SPME-GC analysis. Copper (2.5 mg/L) in the model system increased headspace concentration of volatiles (hexanal, butyl acetate, 2-heptanone, and ethyl hexanoate, 0.5 microL/L each) at pH 6.5, but no change in volatility was observed at pH 7.0. At pH 7.5, presence of copper in the artificial saliva decreased headspace volatile concentration. Effect of copper on volatiles at pH 6.5 may be due to increased solubility of copper at lower pH. Copper seems to facilitate hydrophobic binding between mucin and aroma compounds at pH 7.5, possibly by exposing hydrophobic sites of mucin.
A time-intensity (TI) test was performed to identify the effect of pH on temporal characteristics of copper sensation. Metallic taste, bitterness, and astringency were major attributes of drinking water containing 2.5 mg/L and 5 mg/L Cu. All three attributes were responsible for the lingering aftertaste of copper. TI test results of copper solutions did not show a common TI pattern of astringency that is characterized with slow onset and longer duration time. Increase in pH of water from 5.5 to 7.5 inhibited metallic taste of copper, but did not reduce bitterness and astringency. The level of soluble copper at pH 7.5 decreased by 50 % compared to that at pH 5.5. Soluble copper concentration and temporal profile of sensory attributes of copper solutions at different pH levels suggest that soluble copper species decide the perception of copper sensation by controlling metallic taste.
The nature of copper-protein interaction and its implication on mechanisms of sensory perception were studied by investigating binding of copper to high molecular weight fractions of human saliva. At the copper concentration < 10 mg/L, most copper exists as unbound copper form while about 60 % of copper was found in protein fractions or with precipitated salivary debris. This result suggests that copper is in a soluble unbound form in saliva at low concentration (<10 mg/L) and assumed to be available for taste receptors. At higher concentration, copper either becomes insoluble or binds with proteins. Insoluble copper species are thought to cause astringency. When copper was added at the concentration equal to or greater than 10 mg/L, two salivary proteins of molecular weight 29 kDa and 33 kDa formed insoluble complexes with copper. Low molecular weight mucin (MG2), alpha-amylase, basic proline-rich proteins (PRPs), and a protein of MW 45 kDa also bound with copper.
In summary, sensations elicited or influenced by copper are thought to be determined by what copper species are dominant in the mouth. Soluble copper species and insoluble copper species are assumed to interact with different sensory receptors, resulting in metallic taste or astringency. This speciation process is influenced by pH conditions, composition of other electrolytes, and organic chelators such as proteins.Ph. D.

Full textAbstract:
Auditory processing is the ability of the brain to manipulate and utilise the neural output of the ear based on the frequency, intensity, and temporal features of the incoming acoustic signal. An auditory processing disorder (APD) is a deficiency in this ability. One category of tests that examine auditory processing ability are the various versions of the "filtered words test" (FWT), whereby a monaural, low-redundancy speech sample is distorted by using filtering to modify its frequency content. Due to the richness of the neural pathways in the auditory system and the redundancy of acoustic information in spoken language, a normal listener is able to recognize speech even when parts of the signal are missing, whereas this ability is often impaired in listeners with APD. One limitation of the various versions of the FWT is that they are carried out using a constant level of low-pass filtering (e.g. a corner frequency of 1000 Hz), which is prone to ceiling and floor effects. The purpose of this study was to counter these effects by modifying the FWT to use a computer-based adaptive procedure, to improve the sensitivity of the test over its constant-level counterparts. The University of Canterbury Monosyllabic Adaptive Speech Test (UC MAST) was performed on 23 normal adults, and 32 normal children (7 to 11 years of age). The child participants also underwent the SCAN-C test for APD in Children (Revised). Findings indicated a significant maturational effect on the UC MAST. Adult participants performed significantly better on the UC MAST in comparison to the child participants. In addition, adult participants performed the UC MAST more reliably than their younger counterparts. No correlation was found between performance on the UC MAST and SCAN-C test. The development of the UC MAST is discussed and the clinical implications of the findings are explored.
