Computerized adaptive testing: the capitalization on chance problem

This paper describes several simulation studies that examine the effects of capitalization on chance in the selection of items and the ability estimation in CAT, employing the 3-parameter logistic model. In order to generate different estimation errors for the item parameters, the calibration sample size was manipulated (N = 500, 1000 and 2000 subjects) as was the ratio of item bank size to test length (banks of 197 and 788 items, test lengths of 20 and 40 items), both in a CAT and in a random test. Results show that capitalization on chance is particularly serious in CAT, as revealed by the large positive bias found in the small sample calibration conditions. For broad ranges of theta, the overestimation of the precision (asymptotic Se) reaches levels of 40%, something that does not occur with the RMSE (theta). The problem is greater as the item bank size to test length ratio increases. Potential solutions were tested in a second study, where two exposure control methods were incorporated into the item selection algorithm. Some alternative solutions are discussed.     

Associative priming effects with visible, transposed-letter nonwords: JUGDE facilitates COURT

Associative priming effects can be obtained with masked nonword primes or with masked pseudohomophone primes (e.g., judpe?CCOURT, tode?CFROG), but not with visible primes. The usual explanation is that when the prime is visible, these stimuli no longer activate the semantic representations of their base words. Given the important role of transposed-letter stimuli (e.g., jugde) in visual word recognition, here we examined whether or not an associative priming effect could be obtained with visible transposed-letter nonword primes (e.g., jugde?CCOURT) in a series of lexical decision experiments. Results showed a sizable associative priming effect with visible transposed-letter nonword primes (i.e., jugde?CCOURT faster than neevr?CCOURT) in Experiments 1?C3 that was close to that with word primes. In contrast, we failed to find a parallel effect with replacement-letter nonword primes (Experiment 2). These findings pose some constraints to models of visual word recognition.     

Sexism, Vocational Goals, and Motivation as Predictors of Men’s and Women’s Career Choice

In the present study we analyzed the impact of vocational goals, sexist attitudes toward women, and motivation on career choice, in a sample of 448 Spanish college students (65.2% women and 34.1% men). Although we found some similarities between men and women in terms of their motivational orientations (extrinsic vs. intrinsic) and vocational goals, men’s extrinsic motivations appear to differ depending on the college major. We also found differences in sexist attitudes toward women by gender and chosen major: both male and female students enrolled in technical majors reported the most sexist attitudes (both hostile and benevolent). These findings underline the importance of taking sexist attitudes toward women into account in attempts to explain gender differences in career choice, something which has been largely overlooked in the research to date.     

Properties of the beck depression inventory as a screening instrument for adolescent depression

The utility of the Beck Depression Inventory (BDI) for identifying Major Depressive Episode was assessed with two samples of adolescents, 65 psychiatric hospital inpatients and 49 secondary school students. Diagnoses based on the Child Assessment Schedule served as criteria. With the school sample, a BDI screening score of 16 resulted in 100% sensitivity and 93.2% specificity. For the inpatient sample, a cutoff of 11 yielded a sensitivity of 81.5% and specificity of 52.6%. There was evidence of the BDI's convergent and discriminant validity for both samples. The results were consistent with the assertion that Major Depressive Episode is a sufficiently distinct diagnostic category in adolescence to be detected by a screening measure such as the BDI.This research was supported by grants to the first author from the National Research Council, and to the second author from the Graduate Students Association of Arizona State University. The authors express their appreciation to Camelback Hospitals and to Judson School for their cooperation in arranging for subject participation.     

Self-esteem and job complexity as moderators of performance and satisfaction

Self-esteem and job complexity were investigated as moderators of self, supervisor, and peer ratings of performance and satisfaction with work, supervisors, and peers testing balance and activation theories. One hundred and fifty-three registered nurses served as subjects. Measured self-esteem was not significantly related to the performance or satisfaction measures. Rather, the important variable was perceived job complexity as predicted by Scott's activation theory. Self-ratings of performance and satisfaction with work and peers were greatest at optimal complexity with lower values at high and low complexity. Some support was found for self-esteem as a moderator of the relationship between performance and satisfaction measures in line with Korman's formulations.     

SOCIAL CONFORMITY AND PSYCHOLOGICAL DIFFERENTIATION12

This study examined the role of socialization experiences in the development of psychological differentiation. In each of three countries (Holland, Italy, Mexico) two villages were selected as presenting a contrasting picture with regard to degree of emphasis on conformity to family, religious and political authority. It was hypothesized that within the pair of villages in each country children from the village which stressed social conformity would tend to be more field dependent and show other signs of less developed differentiation than children from the village in which social conformity was less emphasized. In each of the six villages approximately 100 children (boys and girls, aged 9–11 and 13–15) were studied. Differentiation was assessed by a battery of tests of field-dependence-independence and the figure-drawing test. In every comparison of mean test scores between pairs of villages, in each of the three countries, children from the village in which social conformity was stressed obtained scores reflecting less differentiated functioning. Village differences were significant for every measure of differentiation in all three countries. Addition alanalyses of the data from the tests of differentiation and other tests used yielded results essentially consistent with findings from previous studies.     

A comparison of stress-reduction behavioral counseling and contingent nocturnal EMG feedback for the treatment of bruxism

This study compared the efficacy of two treatment modalities (stress-reduction behavioral counseling and contingent nocturnal EMG biofeedback) on night-time bruxism. The 16 subjects (Ss) were assigned sequentially to one of four treatment groups: (1) stress-reduction behavioral counseling: (2) nocturnal biofeedback; (3) stress-reduction behavioral counseling and nocturnal biofeedback; and (4) waiting-list control group. A portable EMG unit was used to record the nightly total of electrical activity (?20 μV) from the masseter muscle 10 days before and after treatment. The three treatment procedures were found to be significantly superior to no-treatment control group. The outcome of the two treatments which made use of stress-reduction behavioral counseling, although better than the treatment which solely used nocturnal biofeedback, was not significantly better. This study demonstrates that stress-reduction skills learned while awake can have a generalized effect on stress-induced muscle activity during sleep. Implications for further research are discussed.     

Personality characteristics of successful applicants to the priesthood

This study investigated personality characteristics of successful pastoral candidates to a major Catholic religious order. Personality measures (i.e., MMPI-2 and 16PF) were administered to 21 male applicants between 1990 and 1994 who subsequently entered into religious life. Results suggest that these clergy applicants were generally well-adjusted, socially responsible, and interpersonally sensitive. However, results also suggest a tendency for defensiveness. Coping with perceived negative impulses (i.e., anger and hostility) may also be an issue for many. Implications for future research are offered.     

Personality and cognitive functioning among hospitalized sexual offending Roman Catholic priests

A tremendous amount of media attention has been directed towards sexual abuse perpetrated by Roman Catholic priests in recent years. While there are countless research studies on both sexual abuse victims and perpetrators in the professional literature, very few have specifically investigated Roman Catholic priests who sexually abuse minors. The purpose of this study is to investigate the role of personality and cognitive variables among hospitalized sex offending Roman Catholic priests using specific MMPI-2, WAIS-R, and Halstead-Reitan measurements. Specifically, the role of defensive coping styles as measured by the L, K, O-H, and R scales of the MMPI-2 along with IQ scores from the WAIS-R and the Halstead impairment index were investigated. A total of 160 Roman Catholic priests (80 who sexually abused minors and 80 nonabusing control patients) hospitalized in a private psychiatric facility specializing in the diagnosis and treatment of clergy were evaluated. Results suggest that overcontrolled-hostility (O-H) was the most reliable predictor of group membership while Verbal IQ approached statistical significance. Implications for further research are offered.     

The Anxiety Response: Concordance Among Components

Under social-evaluative stress, self-reported distress (cognitive and somatic symptoms), behavioral anxiety (motor, facial, verbal, and social), physiological arousal (heart rate and skin resistance), and task performance (cognitive and motor) were recorded. Concordance was selective and consistent across response systems. There were significant relationships among measures of cognitive aspects, and among those concerned with somatic aspects, but not between these two areas. Furthermore, concordance was much higher in high-than in low-trait/test-anxiety participants, who even exhibited reversed concordance. These differences are explained in terms of stronger physiological signals in high trait/test anxiety. Alternative interpretations involving perceiving and/or reporting internal threat-related information in low trait/test anxiety are discussed.
