Examination Of The Cognitive Mechanisms Underlying Evaluative And Semantic Priming Effects By Varying Task Instructions: An Erp Study, Jennifer Hilda Taylor

Open Access Theses & Dissertations

This study examined the cognitive processes that underlie stimulus identification and the activation of attitudes by investigating behavioral and psychophysiological effects in a priming paradigm. Cognitive mechanisms were investigated by examining evaluative and semantic priming effects on behavioral response times, the N400, and LPP event-related potential (ERP) components by varying tasks between-subjects. Participants either completed an evaluative task, a semantic task, or a feature-detection task. It was hypothesized that the behavioral evaluative priming effect would occur in the evaluative task and that the behavioral semantic priming effect would occur in the semantic and feature-detection tasks. The N400 was hypothesized to …

Threat By Association: Minimal Group Affiliation And Its Outcome For Stereotype Threat, Eric W. Fuller

Wayne State University Theses

Stereotype threat has been shown to be an important cause of performance detriments in various social groups. It has also been theorized that stereotype threat could be applicable to any group so long as the individual believes their performance may reinforce the negative stereotype. The current work attempts to induce stereotype threat in participants believing they belong to an experimentally created and negatively stereotyped group using a minimal group paradigm. Across two studies there did not appear to be significant performance changes typically observed in stereotype threat research. Various cognitive measures and post-performance inquiries did generally support claims that participants …

Lateral Cognitive Processing And Belief Updating, Erin Marie Holcomb

Wayne State University Theses

Bias in mental representations and belief systems has been linked to asymmetries in information processing by the two hemispheres in research that uses wide variety of methodologies and participant samples. Also, associations have been drawn between such biases in belief systems and sociopolitical orientation leading to the hypothesis that links can be drawn from lateral processing through cognitive style to social and political orientation. This study sought to examine individual differences in laterality - as assessed via a lateralized semantic priming methodology - and manifestations of rigidity and flexibility in belief updating within a sociopolitical context. Analyses revealed that a …

Statistical Bootstrapping Of Speech Segmentation Cues, Nicolas O. Planet

Masters Theses 1911 - February 2014

Various infant studies suggest that statistical regularities in the speech stream (e.g. transitional probabilities) are one of the first speech segmentation cues available. Statistical learning may serve as a mechanism for learning various language specific segmentation cues (e.g. stress segmentation by English speakers). To test this possibility we exposed adults to an artificial language in which all words had a novel acoustic cue on the final syllable. Subjects were presented with a continuous stream of synthesized speech in which the words were repeated in random order. Subjects were then given a new set of words to see if they had …

Modeling Source Memory Decision Bounds, Angela M. Pazzaglia

Masters Theses 1911 - February 2014

Current Signal Detection Theory models of source memory necessitate assumptions about the underlying distributions of source strengths to describe source memory performance. The current experiments applied a modified version of the same-different task in order to plot individual memory stimuli along a controlled dimension of the average frequency of voices. This technique allowed us to determine that subjects were using an independent-observations strategy rather than a differencing strategy when deciding whether two test words were spoken by the same or different female speakers at study. By including two male and two female voices and changing the task distinction from same …

Implicit Theories Of Ability Of Grade 6 Science Students: Relation To Epistemological Beliefs And Academic Motivation And Achievement In Science, Jason Chen, Frank Pajares

Articles

We investigated (a) the associations of implicit theories and epistemological beliefs and their effects on the academic motivation and achievement of students in Grade 6 science and (b) the mean differences of implicit theories, epistemological beliefs, and academic motivation and achievement as a function of gender and race/ethnicity (N = 508). Path analysis revealed that an incremental view of ability had direct and indirect effects on adaptive motivational factors, whereas fixed entity views had direct and indirect effects on maladaptive factors. Epistemological beliefs mediated the influence of implicit theories of ability on achievement goal orientations, self-efficacy, and science achievement. Results …

A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

As a fundamental part of our daily lives, visual word processing has received much attention in the psychological literature. Despite the well established perceptual advantages of word and pseudoword context using accuracy, a comparable effect using response times has been elusive. Some researchers continue to question whether the advantage due to word context is perceptual. We use the capacity coefficient, a well established, response time based measure of efficiency to provide evidence of word processing as a particularly efficient perceptual process to complement those results from the accuracy domain.

Extension Of The Theory Of Planned Behaviour Incorporating An Improved Measure Of Emotion: An Application To Speeding, Chloe Jones

Theses : Honours

Speeding is related to crashes. The motivational factors underlying speeding must be identified to inform road safety. The Theory of Planned Behaviour (TPB) suggests that behavioural intention is predicted by attitude, subjective norm and perceived behavioural control. The present research was an attempted extension of the Theory of Planned Behaviour (TPB), in a speeding context. It was identified that the scales used in the TPB are not appropriately capturing emotion, and that the lack of emotion measures may be responsible for unaccounted for variance in intention. Questionnaires were developed based on Ajzen's (2006) and Bradley and Lang's (1999) methods. It …

Factors that have been demonstrated to positively impact on the mental and physical health of parents of children with an intellectual disability include greater clinical, family and social supports. One avenue of support that has been rarely explored is the role of spirituality and organised religion in supporting parents of children with an intellectual disability. Aim: The aim of this literature review was to investigate the role of spirituality and organised religion in the lives of parents of children with intellectual disability, specifically Down syndrome. Methods: …

The Experience Of Single Mothers: Resilience In Their Multiple Roles, Sharon Cheeseman

Theses : Honours

Single motherhood has been identified as a challenging role, with disadvantages including financial hardship and poor mental health. Resilience is a multidimensional construct, where two conditions need to occur: some form of adversity and positive adaptation. Resilience may empower single mothers to face the challenges whilst leading psychologically healthy and productive lives. Participants in this qualitative research study were ten West Australian single mothers, aged 35 to 45 years. A phenomenological methodology was used to understand their experiences with information collected through in-depth interviews and the Resilience Scale for Adults, used to complement the qualitative findings as descriptive support. Qualitative …

Facebook Usage Predicted By Sense Of Community And 'Loneliness', Alison Bagworth

Theses : Honours

Facebook Usage Predicted by Sense of Community and 'loneliness' Face book is one of a growing number of social networking sites (SNSs) that are currently being used by young adults to compliment face-to-face interactions. The use of these sites raises questions in relation to how their function may be compared to measurements of more traditional communication. This research measured Sense of Community (SoC) and 'loneliness' in young adults in order to predict usage of Facebook. Participants were 154 Facebook users (82% female, mean age 23.66) who completed an online survey with four components (demographics, Facebook usage, SoC Index, and …

The Experiences Of Incarceration On Indigenous Parents And Primary Care-Givers Of Juvenile Detainees, Simone Reid

Theses : Honours

Incarceration impacts on a number of people, not just the person sentenced. It has been suggested that the family of the prisoner can experience the prison sentence just as much, albeit differently, as the prisoner themself. Families remain important, as those prisoners who return to strong family networks are at less risk of recidivism. National research has been used to inform policy-makers, but every State has unique characteristics. The overrepresentation of Torres Strait Islander and Aboriginal juveniles in juvenile detention, especially in Western Australia, has been well-documented. However, research examining the experiences of incarceration on family members is limited. This …

An Exploratory Study On The Perspectives Of Western Australian Drivers Towards Responding To Emergency Vehicles, Pauline Grant

Theses : Honours

Failing to give way to emergency vehicles has resulted in one crash per day on Australian roads (NRMA, 2009), and delayed emergency service responses to situations that constitute a serious threat to life and/or property. With an anticipated population increase in Western Australia (ABS, 2009) this problem will only worsen. Whilst there have been attempts to address the problem through information leaflets and media campaigns, the success of such initiatives is not clear because of a lack of empirical assessment. The little research available in the area, focused on crash scenarios, emergency vehicle drivers, or other non-psychological processes. The current …

The Effect Of Motivation, Social Support, Stress And Resilience On The Development Of Burnout Symptoms In Elite Athletes, Blythe Gooden

Theses : Honours

The purpose of this review was to provide an overall view of some of the identified determinants of burnout when it occurs in elite athletes. A total of 66 published articles were used to develop an understanding of burnout, its contributors and the combined effects of the contributors. An explanation of the psychological concept of burnout is discussed, followed by a discussion of the implications of burnout in athletes. Current literature in the area is reviewed followed by an overview of three of the identified determinants of athletic burnout: 1. Stress based on theoretic concepts developed by Lazarus and Folkman …

Foreign Language Comprehension: Understanding The Centrality Deficit, Amanda C. Miller

Electronic Theses and Dissertations

The goal of this study was to determine how reading in a foreign language (L2) affects one's mental representation of the text and the ability to recognize and recall the text's important information. Using a within-participants design, the proportion of central and peripheral ideas recalled by participants reading in their L2 was compared to that when reading in their native language (L1). Readers recalled a greater proportion of central than peripheral ideas when reading in both their L2 and L1, but when their L2 and L1 recalls were directly compared, a very interesting, yet counterintuitive, result emerged. The greatest deficit …

Tackling Ocd: Talk Is Not Cheap!, Christina J. Taylor

Psychology Faculty Publications

Cognitive Therapy offers techniques to help identify ways and patterns of thinking that produce distress, negative behavior, and poor motivation. Cognitive techniques can help improve an individual’s motivation to tackle their OCD, help change their reaction to and interpretation of their obsessions, and help them to cope with the anxiety they experience when they carry out an exposure and response prevention regimen.

The Effect Of Word Sociality On Word Recognition, Sean Seaman

Wayne State University Dissertations

While research into the role of semantic structure in the recognition of written and spoken words has grown, it has not looked specifically at the role of conversational context on the recognition of isolated words. This study was a corpus-based and behavioral exploration of a new semantic variable - sociality - and used on-line behavioral testing to obtain new word recognition data using the visual and auditory lexical decision tasks. The results consistently demonstrated that sociality is one of the most robust predictors of lexical decision performance. Overall, it appears that the visual lexical decision task is quite sensitive to …

Communicative Competence In Persons With Aphasia: The Impact Of Executive Function, Judy Marie Mikola

Wayne State University Dissertations

The purpose of this study was to examine the relationship between executive function and performance on selected linguistic tasks in persons with aphasia secondary to left frontal lesions.

A group of 15 persons with aphasia (PWA) completed three communication board tasks of varying levels of complexity and structure. The subject's functional use of the picture/word communication board was tested during a Story Retelling task. In addition, the PWA's executive function skills were examined using six nonverbal tests. The PWA group performance scores were compared to that of the neurologically healthy control group.

Results demonstrated that the control group performed significantly …

Children's Tolerance Of Word-Form Variation, Paul Reeves Breuning

Dissertations, Theses, and Capstone Projects

This study compared children's (N=96, mean age 4;1, range 2;8-5;3) and adults' (N=96, mean age 21 years) tolerance of word-onset modifications (e.g., wabbit and warabbit) and pseudo affixes (e.g., kocat and catko) in a label extension task. Trials comprised an introductory phase where children saw a picture of an animal and were told its name, and a test phase where they were shown the same picture along with one of a different animal. For `similar-name' trials, participants heard a word-form modification of the previously introduced name (e.g., introduced to a dib, they were asked, `which animal is a wib?'). For …
