In order to test one implicit assumption of a neuropsychological theory concerning Complex Partial Seizure Disorder and affective-behavioral change, an instrument has been developed. The Perception of Affect Task (PAT) was created to fill an unmet need for an instrument which could assess the perception of affective stimuli across six emotions and neutral by: (1) allowing for a comparative analysis of perceptual abilities relative to the various emotions; (2) allowing for a comparative analysis of verbal and nonverbal perceptual abilities, thereby allowing for a potential analysis of enhancements and/or deficits by hemispheric laterality; and (3) assessing perceived intensity ratings of affective stimuli. As the PAT is to evaluate, in an upcoming study, CPS patients' deviations from normal perception-of-affect abilities, the present study serves to standardize this instrument with a college student sample.

The purpose of the current study was to investigate three aspects of the construct validity of attributional style assessment instruments. The first purpose was to determine the independence of stability and globality. The second was to determine if controllability was a dimension of attributional style. The third purpose was to determine if inventories that use real or hypothetical events measure attributional style equally well. One hundred fifty-nine female, and one hudred fifty-five male subjects, completed four questionnaires that assessed attributional style. Results provided some support for the general construct of attributional style. All four factors were found, which demonstrates the support for the four factor model. However, the two factor model may be the best overall method. No method factor (real or hypothetical stimulus event) solution was obtained. Possible sex differences are discussed. The findings are discussed in terms of attribution theory. Suggestions for further research are presented. / Department of Psychological Science

The purpose of this study was to investigate the construct validity of the eight subscales of the Cambridge Cognitive Examination (CAMCOG). A confirmatory factor analysis was conducted to determine if the subscales of the CAMCOG, as proposed by its authors (Roth et al., 1986), were able to adequately describe the total set of relations among the set of individual scale items.The subjects consisted of 224 male and female individuals obtained through a study to examine the validity of the CAMCOG on a United States population. The subjects were divided into two separate groups: those diagnosed as having a dementing illness and a normal comparison group. The CAMCOG was administered to each subject as a measure of neuropsychological functioning by a trained professional or paraprofessional.Two models were established a priori for the confirmatory factor analysis. The first model was based on the theory of Roth et al. (1986) which suggested there are eight factors within the CAMCOG. The second model was developed as a one-factor solution and was based on the present author's theory that the CAMCOG is a general measure of brain impairment and that all data would be best explained by one common factor. Maximum likelihood estimates were calculated using LISREL VII (Joreskog & Sorbom, 1989).The results of the study suggest that the eight-factor model of the CAMCOG proposed by its authors (Roth et al., 1986) provided a significantly better explanation of the data than did the one factor model proposed by the author of this study. However, neither one of the models postulated was found to adequately describe the covariance of the obtained data. Accordingly, the validity of the constructs of the CAMCOG as proposed by Roth et al. (1986) is considered to be questionable.

In order to compare the effectiveness of four dissimulation detection techniques, a revised and shortened version of the California Psychological Inventory (CPI) was administered to 12E college students under three instructional sets. Honest, fake good, and fake bad instructional sets were used in a within-subjects design to identify dissimulation of the managerial potential scale (Mp) of the CPI. An obvious -subtle (0-5) scale tested against the L and K scales of the Minnesota Multiphasic Personality Inventory (MMPI) and the good impression (Gi) scale of the CPI. Subjects were randomly assigned to six counterbalanced conditions. Difference scores from the (honest - fake good) and (honest â fake bad) were computed and regressed against each detection technique. Analysis of covariance was also completed in order to correct for possible low reliability of the difference scores. The results demonstrated that the Mp scale is susceptible to dissimulation, the best scale for identifying honest profiles was the L scale and the best scales for detecting dissimulation is the Gi or K scales. Intelligence was found to be a good predictor of faking good but not faking bad. All of the scales produce desparate impact in regards to sex. The question of whether faking good and faking bad are two different phenomena is discussed. / Master of Science

Indiana University-Purdue University Indianapolis (IUPUI) / Ecological momentary assessment (EMA) has been asserted by proponents of the technique as being superior to standard paper-and-pencil measurements in terms of the reliability and validity of the information obtained; however, this claim has not yet been fully evaluated in the literature. Accordingly, the purpose of this study was to evaluate one aspect of this assertion by comparing the utility of EMA and retrospective measures of depressive symptoms in predicting health-relevant biological and behavioral outcomes. It was hypothesized that (1) the EMA measure will have better predictive utility when examining objective sleep quality (a biological outcome), and that (2) the retrospective measure will have better predictive utility when examining blood donation intention (a behavioral outcome). Ninety-six undergraduate females participated in this 2-week study. Depressive symptoms were measured momentarily and retrospectively using the Center for Epidemiological Studies-Depression Scale (CES-D). The biological outcome was assessed by actigraphy, whereas the behavioral outcome was measured via a self-report questionnaire. Unfortunately, it was not possible to fully test these hypotheses due to the failure to observe relationships between the predictor variables and the outcomes. The reported results, although limited, did not provide support for the hypotheses. Supplemental analyses revealed a moderate to high amount of shared variance between the EMA and retrospective measures, a similar extent of random error in both measures, and potentially a greater degree of systematic error in the retrospective measure. Due to the paucity of literature examining the claim of superior reliability and validity of EMA versus retrospective measures, as well as the failure of the current study to evaluate this assertion sufficiently, it appears that this claim remains unfounded. Therefore, suggestions for future research are provided.

The objective of this study was to investigate how well the academic performance of the Industrial and Organisational Psychology master’s students at a research institution can be predicted through psychometric measures. A non-experimental design was used in this empirical study. The sample consisted of one hundred and thirty-three IO Psychology master’s students over a five-year period. The secondary data for this research originated from the students completing the Graduate Verify Ability tests as well as the Occupational Personality Questionnaire, which are psychometric measures that form part of the selection. Both psychometric measures load onto the Person Job Match competencies. A theoretical relationship could be found between the Ability tests and academic success as well as the PJM competencies that included weighted scores from both psychometric measures. The empirical relationships, therefore, proved that the ability tests have the strongest predictive ability for academic success. / Industrial and Organisational Psychology / M. Com.
