Since its creation in 1998, the Implicit Association Test (IAT) has become a commonly used measure in social psychology and related fields of research. Studies of the cognitive processes involved in the IAT are necessary to establish the validity of this measure and to suggest further refinements to its use and interpretation. The current thesis used ERPs to study cognitive processes associated with the IAT. The first experiment found significant differences in P300 amplitude in the Congruent and Incongruent conditions, which were interpreted as a reflection of greater equivocation in the Incongruent condition. The second experiment tested the task-set switching account of the IAT in much greater detail by analyzing each trial type separately. In the Congruent condition, all trial types elicited the same amplitude P300. Local probability, and the consequent checking and updating of working memory, was thought to be responsible for differences between trials of the Incongruent condition that required or did not require a task switch. The final experiment examined the role of working memory in the IAT by introducing obtrusive and irrelevant auditory stimuli. The results of Experiment 3 indicated that the introduction of an obtrusive and irrelevant auditory increment deviant has little overall effect on the IAT, and a similar effect on switch and no-switch trials within the Incongruent condition. This could have been because both the Congruent and Incongruent conditions of the IAT make such extensive demands on central processing resources that few are available to allow for the switching of attention, or it is possible that the IAT does not require significant updating of working memory. The usefulness of ERPs in the study of the IAT effect is demonstrated by the current research. In particular, the finding that behavioural results were not always consistent with the ERP results demonstrates that electrophysiological measures can complement traditional behavioural measures.

Many cognitive resources contribute towards the appraisal of stressors. Of these, self-efficacy (SE) is widely acknowledged to play a significant role in protecting adolescents from the effects of stress (Bandura, 1997). This study investigated that relationship through the use of a quasi-experimental methodology (Cook & Campbell, 1979) utilising an untreated Control group of 44 adolescent, female participants and an Experimental group of 70 additional participants, all of whom were volunteers drawn from the Sixth Form of a single participating school. The members of both participant groups took part in two rounds of testing, between which the members of the Experimental group were exposed to a significant academic stressor (one or more public A-level examinations). During both test phases, all participants completed the 10- item Perceived Stress Scale self-report (Cohen & Williamson, 1988), the Examination Self-Efficacy Scale instrument (Schwarzer & Jerusalem, 1995) and a bespoke Implicit Association Test (Greenwald et al., 1998) designed to measure implicit stressor appraisal. Significant trends were identified by means of ANCOVA, correlation and regression analyses, and the resulting data were interpreted in terms of a dual process model of stress (Compas, 2004). Results not only concurred with those of previous studies (e.g. Betoret, 2006; Vaezi & Fallah, 2011) by demonstrating a strongly negative correlation between acute academic stress and academic SE, but provided new evidence to suggest that the ‘protective’ effect of SE occurs via a buffering mechanism at the level of preconscious stressor appraisals (Bargh, 1990), which limits the effect of acute stress exposure on preconscious stressor appraisals (e.g. Luecken & Appelhans, 2005).

Thesis advisor: Andrea Heberlein / Dehumanization of outgroup members in situations of intergroup competition has been widely reported (Haslam, 2006), but the effects of individual competition on dehumanization have not yet been extensively explored. A previous study in our lab examined this effect and found an unexpected gender difference, with women showing greater implicit dehumanization than men. The present study aimed to explore a possible mechanism for that gender difference: gendered expectations of maintaining positive interpersonal relations, and subsequent discomfort in competitive situations, may motivate the implicit dehumanization of competitors. Participants interacted briefly with a confederate and were then given instructions for a competitive or non-competitive game. Participants then completed two Single-Category Implicit Association Tests measuring dehumanization of their game partner. Participants also completed the Mind Perception Questionnaire, which measures explicit dehumanization of participants’ game partners. We predicted that in the Competition condition, female participants would implicitly dehumanize their game partners more than men would. / Thesis (BA) — Boston College, 2018. / Submitted to: Boston College.

The present study was designed to examine the relationship between Mednick's Remote Associates Test and Pettigrew's Category-Width Test. The sample was made up of 36 educational psychology students enrolled in the Utah State Summer School. The correlation for males and females was made independently. Although the males showed a higher correlation between the two tests than did the females (males, .296 and females, .058), the correlations were not statistically significant. No full explanation was given for the lack of correlation between the category-width scores and the RAT scores except for the qualification that the RAT may be measuring a different type of creativity than what the category-width test is measuring.

Dissertation (Ed.D.)--Boston University, 1970. / The purpose of this study was to determine whether or not semantic flexibility as a language characteristic of teachers in training could be used as a predictor of the teacher's ability to receive and transmit information. The Guilford Word Association Test, designed by J. P. Guilford to measure convergent and divergent thinking, was selected as the instrument for measuring semantic flexibility and was administered to 201 students enrolled in the block methods course at Boston University. The students were all juniors, scheduled to student teach the following semester. The Guilford Word Association Test was also administered to 154 sixth grade children enrolled in the Boston Public Schools in the South End and Roxbury and to 182 sixth grade children enrolled in the Newton Public Schools. The two groups of children were designated as the urban and suburban samples, respectively. From the populations tested four high Guilford teachers and four low Guilford teachers were selected. From each of the urban and suburban classes four high Guilford and four low Guilford children were selected. Each teacher had eight pupils assigned to her and for the purposes of data analysis, the children were categorized first as high and low Guilford scorers and then as urban or suburban children. In total there were eight teachers and sixty-four children in this experiment. [truncated]
