Indiana University-Purdue University Indianapolis (IUPUI) / This study examined the roles of commitment and attributions in uninvolved partner responses to imagined sexual infidelity. Undergraduate students (N = 298) in dating relationships participated in a hypothetical sexual infidelity scenario in which they imagined their romantic partner engaged in sexual intercourse with someone else. Measured-variable path analysis was used to evaluate the predictive ability of commitment and attributions on negative emotional responses and predicted relationship continuation. The hypothesized conceptual model demonstrated poor fit to sample data. Through exploratory model building, an alternative model was generated that demonstrated good fit to sample data. A subset of commitment, investment, predicted negative affect. In addition, attributions predicted predictions of relationship continuation. Negative emotional responses were highly endorsed on a validated measure for emotional responses, the PANAS-X (Watson & Clark, 1994). Further, study findings highlight the importance of the use of a compliance check in assessing successful participant completion of imagined infidelity scenario. Unique study contributions include directions for further conceptual model development for this area of research as well as support for the use of compliance checks and careful selection of infidelity scenario.

Indiana University-Purdue University Indianapolis (IUPUI) / Stress has been shown to contribute to alcohol drinking; however, inconsistencies in both the clinical and pre-clinical literature speak to the need for better paradigms to study this interaction. The present experiments compared animal models of the propensity to consume ethanol, the selectively bred alcohol-preferring (P) and high-alcohol-drinking (HAD) rat lines, in their response to yohimbine on ethanol seeking and self-administration and anxiety-like behavior. The P and HAD lines consume similar amounts of ethanol, yet differ in apparent motivation to drink ethanol, in anxiety-like behavior, and response to stress in alcohol drinking. Therefore, it was of interest to determine whether stress may differentially affect ethanol-motivated behaviors between the P and HAD lines. Acute administration of yohimbine, an α-2 adrenoreceptor antagonist that increases anxiety and activate stress systems, increased operant ethanol self-administration and reinstatement of ethanol seeking in P rats, and free-choice ethanol drinking in both P and HAD rats. However, acute yohimbine administration decreased ethanol drinking when given limited access in the home cage, an effect that was diminished by extending the pre-treatment interval or increasing the number of ethanol exposure sessions. Yohimbine did not alter appetitive responding during a non-reinforced trial, nor did yohimbine alter the acquisition of free-choice ethanol drinking. Exposure to alcohol deprivation resulted in modest increases in ethanol intake, but yohimbine did not potentiate this effect. While acute yohimbine administration increased anxiety-like behavior, prior experience with repeated yohimbine exposures or with repeated deprivation periods did not. P rats were shown to be more active and less anxious and to display greater responding during a non-reinforced trial than HAD rats. Taken together, the results of these experiments demonstrate that the timing of yohimbine exposure relative to ethanol access is a critical component to determining its effects on ethanol seeking and self-administration and anxiety-like behavior. Further investigation into the parameters under which stress alters the motivation to seek and consume ethanol between these selectively bred lines is warranted, and future work that incorporates therapeutic agents aimed at reducing stress reactivity and alcohol drinking could elucidate effective strategies in the treatment of alcoholism.

The utilisation of navigation systems in cars has given rise to road safety concerns, and the design and functionality of such systems must therefore be adjusted to the users’ needs, since they have to divide their attention between driving and the operation of the navigation system. The study was aimed at finding the optimum system response time (SRT) which would enable a driver to focus as much as possible on the road while attaining an efficient task completion time using an electronic navigational system. The research project consists of two separate experiments and was completed by 10 subjects. Experiment 1 included a temporal reproduction task and a secondary memory task. The subjects had to memorise two symbols and then reproduce six time spans ranging from 1 to 30 s to provide a baseline measurement of their time estimation abilities. Experiment 2 consisted of a simulated automobile driving task. While driving in the simulator the subjects completed a memorising task displayed on a touch screen. The task was presented with seven different system response times (SRTs) ranging from 0 to 30 s. The effects of different SRTs on the eye movement from road to monitor, regarding the duration of fixation and the frequency of change were evaluated. The distribution of gazes to the secondary task was analysed to provide information about the time estimation performance in the driving simulator. Other dependent variables tested were the accuracy of selected items, memory game performance, drive performance and the subjective state of the test person. The results of this study can be employed to find the optimum duration of inter-task delays for in-vehicle technical devices. / Psychology / M.A. (Psychology)

This study addresses young children's involvement with comfort objects, including why children have them, how they are used, when attachments to such objects are cause for concern and how teachers and parents can respond to promote the young child's development. The child's becoming and development is examined in this study. The researcher also reviews major transitional object theories in terms of origin, development and psychological meaning. This study aims to explore this phenomenon from a psychological - educational perspective and to formulate a set of guidelines for parents and professionals whose children use comfort behaviour. Information was collated from case studies, a questionnaire and a detailed study of literature. / Psychology of Education / M. Ed. (Guidance and Counselling)

The purpose of the study was to develop a behavioral nursing intervention strategy for specific deficits in grooming performance of elders with dementia. A quasi-experimental two-group design using switching replications with removed intervention was employed. Three residents with severe cognitive impairments and three residents with mild cognitive impairments were chosen from a special dementia care unit of a long-term care facility. Three residents among six residents were randomly selected to receive the behavioral intervention early. Baseline and post-intervention assistance was provided by nurse aides. Each resident was asked to wash hands, brush teeth, wash face, and comb hair in a sequence. Ten intervention sessions were conducted by the trained intervener for two consecutive weeks. The intervention consisted systematic prompting and social reinforcement. A total of 21 sessions were collected in the morning using videotape recordings. Interobserver agreement for the instruments designed by the investigator was measured by the trained observers. Data were analyzed in two phases. First, the quantitative data were analyzed to determine the independent functional behaviors of individuals, and the change in the intensity of nursing effort associated with grooming of elders with dementia. Data were examined by individual graphic display throughout the three phases (baseline, nursing intervention, post-intervention). Second, the qualitative data were analyzed to determine the antecedents, consequences, and resident responses associated with grooming, the caregiver problem behaviors, and resident problem behaviors associated with grooming performance. The results show that the functional behaviors of even severely demented elders can be promoted, indicating the effectiveness of nursing care strategies on the ADL task of grooming. The data in this research suggest that maintaining or improving functional ability is possible with a behavioral nursing intervention, which was a highly structured and systematic approach that involved modifying the environmental and behavioral context, through strategies such as prompting and social reinforcement, when necessary. Furthermore, through the qualitative analysis, the functional relationships between antecedents, consequences, and behaviors of demented elders allowed the investigator to analyze the caregiver problem behaviors and resident behavior problems associated with grooming.

This research investigated students‘ views on the inclusion of multicultural perspectives into the psychology curriculum at two South African universities.54 students from the University of KwaZulu-Natal (UKZN) and a university in the Gauteng province participated in the research. The age of the participants ranged from 20-40 years. Purposive sampling was used to collect the data. Using a competency scale adjusted to suit a South African context participants were asked their views on a) the practice and supervision of psychology b) diversity in student representation c) students were also asked to rate how competent they were in multicultural issues d) research considerations e) if the physical environment reflected diversity. The students were of the view that South African universities have not adequately incorporated multicultural issues, African perspectives in particular, into the curriculum. The recommendations for future research, including curriculum transformation, are highlighted. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.
