Construct validity and test-retest reliability of a date rape decision-latency measure

In two studies, the construct (convergent and discriminant) validity and test-retest reliability of a date rape decision-latency measure was examined. In Study 1, 174 college men completed measures related to sexual aggression and listened to an audiotaped simulation of a date rape, during which cues of nonconsent and force gradually escalated over time. Participants were instructed to respond, by pressing a button which recorded the latency of their decisions in seconds, if and when they believed the man depicted in the scenario should stop his sexual advances. Results demonstrated positive associations between prolonged decision latencies and sexually aggressive behavior, calloused sexual beliefs, acceptance of interpersonal violence, and sexual promiscuity. In Study 2, initial results were cross-validated in a sample of 102 college men, and discriminant validity was established as decision latencies were unassociated with measures of social desirability, alcohol consumption and drug use. Test-retest reliability assessed over a 2-week interval was .87.The authors wish to thank Alan Gross and Brian Marx for providing the audiotaped stimulus materials, Richard Marsh for writing the decision-latency computer program, Jason Hicks for assisting with programming, and the undergraduate research assistants for serving as experimenters.     

Functions of the environment in behavioral evolution

This paper explores some of the ways in which the environment functions with respect to behavior within an explanatory framework analogous to that of evolutionary biology. In both the behavioral and organic domains, the environment functions differently with respect to individual occurrences and evolutionary units. Within the behavioral domain, the problem of accounting for an occurrence of an operant instance differs from that of accounting for the existence of the operant unit of which the instance is a part. Maintaining these distinctions in levels of analysis within the behavioral domain, we focus first on operant units and operant instances as products of evolutionary processes occurring in the behavioral domain and second upon the causal role of the environment with respect to the existence of operant units and the occurrence of operant instances. The environment's function is selective with respect to origin, maintenance, suppression, and extinction of behavioral populations. At the level of operant instances, the environment has instantiating functions-evocative or alterative. Evocative functions are exemplified by discriminative relations, and alterative functions include both conditional and motivative relations. Implications are considered regarding extension of the analogy to more complex behavior-environment relations.     

Frequency ratios and the discrimination of pure tone sequences

We examined the effect of frequency ratios on the discrimination of patterns of alternating pure tones (ABABA). Listeners heard a repeating pattern presented in transposition (same frequency ratios between successive tones, different absolute frequencies) and were required to indicate when the pattern changed (different frequency ratios and absolute frequencies). Changes from patterns with simple frequency ratios to those with more complex ratios were more readily detected than were changes from complex ratios to simpler ratios.     

Detection of a Cry for Help on the MMPI-2: an analog investigation

We compared Minnesota Multiphasic Personality Inventory (MMPI-2) results from 2 groups of mildly to moderately disturbed psychiatric outpatients (N=60) answering under either Standard or Cry for Help instructions. Results from previously completed intake MMPI-2 protocols were obtained for each participant. The two groups were comparable on intake MMPI-2 variables and demographic characteristics. Analysis of feedback data from the second, experimental observation indicated that the two groups had equivalent self-estimates of understanding of their role and success in simulating their role. Significant differences were found between the two groups on their experimental MMPI-2 protocols. The Cry for Help group had significantly higher scores on F, F-K, Fb, Ds2, and Fp scales as well as significantly lower scorns on the K scale. The Cry for Help group also had significantly higher scores on all clinical scales with the exception of 5, which was not tested. Cutting scores derived by Rogers, Sewell, and Ustad (1995) for the detection of a Cry for Help in outpatients were cross-validated with fairly positive results. Although these results are promising, particularly in light of the shrinkage expected on cross-validation, further research is needed in this area.     

Effects of Self-Appraisal Information, Appraisal Purpose, and Feedback Target on Performance Appraisal Ratings

This experiment investigated the effects of three factors on performance appraisal ratings: self-appraisal information, appraisal purpose, and feedback target. Two hundred and three subjects rated a subordinate's performance on a clerical task subsequent to receiving either a high or low self-assessment. They were told they would provide performance feedback either to the experimenter (organizational agent) or their subordinate, and their ratings would be used either for an administrative decision or developmental feedback. Performance ratings were significantly higher when subjects received a favorable subordinate self-assessment than when self-assessments were unfavorable. A significant interaction was found between feedback target and the appraisal purpose. Implications for the use of self-appraisals in organizations were discussed.     

The psychologist's role in assessing and facilitating patients' knowledge of advance directives in medical settings: A preliminary investigation

In a time of budgetary shortfalls in the medical industry, an aging population, and an increased emphasis on health care choices, psychologists are being called upon to administer advance medical directive programs to patients. This study reports preliminary findings from a program to assess and facilitate patients' knowledge of advance directives (ADs) by the Psychology Service at the Ann Arbor VA Medical Center. The participant pool included 243 male veteran patients admitted to medical and surgical wards at the hospital. The intervention included the use of a computer-generated prompt for consultation, which was sent to the psychology staff in response to a patient inquiry regarding ADs. It also involved an increased emphasis on the delivery of written material on ADs by the admissions clerks. The intervention appeared to result in a modest increase in patients' knowledge of advance directives. Suggestions are offered for areas that should be emphasized in future attempts to increase patients' knowledge and utilization of advance directives.     

Social attitudes of schizophrenics

The Wilson-Patterson Conservatism Scale was given to 34 schizophrenic and 34 non-schizophrenic patients in a Dutch mental hospital. The absence of liberal-scoring schizophrenics was interpreted as consistent with the theory that the social withdrawal seen in chronic schizophrenia represents a strategy for coping with stimulus overload. Internal consistency analysis of C scale performance indicated that this test might be used to assess thought disorder in much the same way as the Bannister and Fransella Grid Test, but a great deal more economically. Furthermore, the questionnaire permits a more detailed examination of the source of inconsistency than does the repertory grid method.
