The Pittsburgh Initial Neuropsychological Testing System (PINTS): A neuropsychological screening battery for psychiatric patients

This paper presents a new neuropsychological screening battery for psychiatric patients. It takes 1.5 to 2 hr to administer and briefly assesses general level of performance, memory, language skills, attention, and spatial-constructional abilities. Scoring and profiling are computerized. Initial validation based on discriminant analysis of a group of brain-damaged and non-brain-damaged psychiatric patients yielded a diagnostic accuracy level of 84.51%. Cross-validation on a different population led to a substantial attrition of classificatory accuracy, but cross-validation based on a comparison between two samples drawn from a homogeneous population yielded substantially less attrition. It was concluded that while the battery discriminates accurately in a homogeneous population, it is necessary to develop separate norms for populations varying in level of impairment.     

Homemaking as an occupational plan: Evidence from a national longitudinal study

While several guidelines for avoiding sexist language in career materials have been published, little empirical evidence exists to support the assumption that sexist language in career information has deleterious effects on clients. The purpose of this study was to explore the effects of sex-biased language in occupational information on subject interest and attitudes regarding gender appropriateness of occupations. Eighth-grade students read occupational briefs on two occupations presented in either neutral, female-biased, or male-biased language. Results showed a nonsignificant language effect and a significant sex difference in interest in the occupations. A significant three-way interaction (language by subject sex by occupation) was found for gender-appropriateness ratings. The findings, together with previous research, suggest that language may have little impact on specific occupational interests, but may affect other career attitudes related to interests.     

Homelessness and dual diagnosis.

People who are dually diagnosed with severe mental illness and substance use disorders constitute 10%-20% of homeless persons. They are a heterogeneous and extremely vulnerable subgroup with complex, poorly understood needs. In this article recent research on the epidemiology, subject characteristics, and service needs of the dually diagnosed homeless population is reviewed. Also, the range of evolving approaches to providing social services, housing, and mental health and substance-abuse treatments; the relevant system issues and legal issues; and problems with current research, as well as future research directions, are discussed. The importance of the distinction between providing appropriate living environments and mental health treatments emerges throughout.     

The Mediational Role of Perceived Competence in Psychological Adjustment to Rheumatoid Arthritis1

Chronic illnesses such as rheumatoid arthritis (RA) have been linked to poor psychological adjustment, although individual differences in this relationship have been observed. This study examines the role of perceived competence as a mediator between RA and adjustment. Persons with RA (N= 208) were surveyed three times at 6-month intervals concerning several potential antecedents of adjustment (pain, psychosocial impairment, social support, and control beliefs), self-perceived level of competence, and level of adjustment (life satisfaction and depressive symptomatology). Within each observational period strong evidence was obtained for perceived competence as a mediator of adjustment. Longitudinally (across the year) the data were consistent with a mediational model, but strong evidence establishing mediation was not obtained. Implications of these findings, and the importance of examining the role of perceived competence in adaptation to chronic illness, are discussed.     

A COMPREHENSIVE EVALUATION OF REINFORCER IDENTIFICATION PROCESSES FOR PERSONS WITH PROFOUND MULTIPLE HANDICAPS

We evaluated comprehensively a preference assessment for identifying reinforcers for persons with profound multiple handicaps. Four experiments were conducted involving 18 individuals. Results of Experiment 1 replicated previous findings in that the assessment identified student preferences for respective stimuli, and caregiver opinion of preferences did not coincide with the systematic assessment. Results of Experiment 2 indicated highly preferred stimuli were likely to function as reinforcers in training programs, whereas stimuli not highly preferred did not function as reinforcers. Results of Experiment 3 suggested the 12 stimuli used in the assessment represented a comprehensive stimulus set for identifying preferences, although the utility of the set sometimes could be enhanced by caregiver opinion. Results of Experiment 4 indicated the assessment identified preferences likely to be maintained over time. Overall, results are discussed in terms of identifying limits and alternatives to a behavioral teaching technology when applied to persons with profound multiple handicaps.     

Processing persuasive arguments: recall and recognition as a function of agreement and manipulated activation asymmetry

Previous research has demonstrated greater attention toward disagree arguments and a greater persuasibility during relative right than during relative left hemisphere activation. This experiment was performed to conceptually replicate and extend these findings to memory stages in the processing of persuasive arguments. The experiment used induction of lateral orientation of attention as the means to selectively activate regions of the brain in normal right-handed subjects. The results showed the expected significant interaction for correct recall as a function of agreement with the argument and hemisphere activated. There was greater recall of agree arguments during left hemisphere activation and greater recall of disagree arguments during right hemisphere activation, as predicted. The effect for recognition memory was in the same direction, but was statistically nonsignificant. These findings support previous research on cerebral asymmetries in the processing of persuasive arguments. This phenomenon is discussed as a possible outcome of asymmetries of affect.     

Anatomy of a DATASIM simulation: The Doob and Gross horn-honking study

The program DATASIM is used to simulate the classic “horn-honking” study by Doob and Gross (1968). In a 2×2 field experiment, Doob and Gross investigated the effects of status of frustrator—a low- or high-status car blocking an intersection—on the latency to honk among male and female drivers. The present paper illustrates how to extract the values of simulation parameters from the published study, how to initialize the simulation in DATASIM, and how to generate and analyze the simulated data. Certain complications arise because the latency data collected by Doob and Gross were nonnormally distributed, cell variances were heterogeneous, and sample sizes were unequal. DATASIM is able to incorporate these features in the simulation, and several methods for assessing the quality of the simulation are illustrated. In addition, sampling experiments are reported, which were performed to assess the joint and individual effects of nonnormality and heterogeneity on the Type I and Type II error rates of theF test. The paper concludes with some practical suggestions regarding how researchers can evaluate, and adjust for, the effects of such violations.
