Deficits in set-shifting ability in nonclinical compulsive checkers

Recent studies suggest deficits in set-shifting ability in patients with obsessive-compulsive disorder (OCD) as measured by tasks such as the Wisconsin Card Sorting Test (WCST; Berg, 1948). The present study examined the extent to which these deficits were demonstrated by nonclinical subjects selected on the basis of their checking scores on the Maudsley Obsessional-Compulsive Inventory. A multivariate analysis revealed that frequent checkers performed significantly worse on the WCST than noncheckers, making more total errors and more perseverative errors and requiring more time to complete the test. A follow-up analysis on a subset of the original sample found similar performance deficits in checkers. While the poorer performance of checkers could be statistically accounted for by anxiety during the first administration of the WCST, anxiety could not explain the relationship between checking status and WCST performance at follow-up. Therefore, there does appear to be some relationship between checking status and WCST performance beyond what can be explained by affective variables.     

Cultural context and substance abuse in Hispanic adolescents

Much emphasis has been placed on the significant substance abuse problem being faced by Hispanic as well as other minority youth in the United States. However, little research has focused on the relative importance of culturally determined factors in the development of substance abuse in Hispanic youths. In this study, we propose an approach to measuring cultural factors through the activity orientations that youths endorse. We studied over 4000 Mexican-American and Mexican youths living along the U.S.-Mexico border with respect to their recent drug use, problem drug use, depressive symptomatology, and their activity orientation. While culturally related activity orientation does significantly increase risk for substance abuse, we found that symptoms of distress/depression and sociodemographic factors exerted a stronger effect on these youths.     

Parent training for attention-deficit hyperactivity disorder: Its impact on parent functioning

This study examined changes in parent functioning resulting from parental participation in a behavioral parent training (PT) program specifically designed for school-aged children with attention-deficit hyperactivity disorder (ADHD). Relative to wait list controls, subjects who completed the nine-session PT program showed significant posttreatment gains in both child and parent functioning, which were maintained 2 months after treatment. In particular, there were PT-induced reductions in parenting stress and increases in parenting self-esteem, which accompanied parent-reported improvements in the overall severity of their child's ADHD symptoms. In addition to their statistical importance, these findings are discussed in terms of their clinical significance, utilizing methods developed by Jacobson and Truax (1991).This project was supported in part through BRSG grant S07RR05712-19 awarded to Arthur D. Anastopoulos by the Biomedical Research Support Program, Division of Research Resources, National Institutes of Health.     

Changes in Fear of AIDS and Homophobia in a University Population

A survey measuring attitudes toward fear of AIDS and homophobia, taken in the fall of 1985, was repeated in the fall of 1989 on the same university population. The results indicated that whereas fear of AIDS decreased, the degree of homophobia remained essentially unchanged. In addition, although respondents were much more knowledgeable about AIDS in 1989 than in 1985, there was no evidence of any change in the relatively high correlation between the fear of AIDS and homophobia.     

FROM DNA TO DEAN

Abstract. In this broadly intellectual autobiographical essay, Arthur Peacocke describes how his educational background at Oxford led him eventually to physicochemical studies on DNA and other biological macromolecules and how biological complexity and the general problems it evokes have remained a recurring theme in his thought. He also describes how, although coming from a relatively non ecclesiastical background, this interest has nevertheless been intertwined with the larger questions to which the Christian faith seeks to respond. He outlines how he has been able to reconcile these two strands in his existence-even to becoming a priest-scientist and eventually the Dean of chapel of a Cambridge college. He reflects on the trends in the relation of religion and science over the last four decades and points to some hopeful developments in the relation between the two communities-and to some unanswered questions.

A robust attribution error in the personality domain

The error of inferring dispositional causes for constrained behavior was investigated in the domain of personality. Subjects were randomly assigned to write essays presenting themselves as strongly introverted or extraverted. Within groups, subjects exchanged essays and estimated the actual (self-rated) introversion/extraversion of the writer. The procedure minimized the likelihood of certain factors conducive to correspondent inference, e.g., the low salience of constraint or nonrepresentative sample of dispositions among essay writers. The experiment included an instructional set variable which involved accentuating the situational constraint or reinforcing the subjects' inclination to individuate the writer. In all conditions, a significant pattern of correspondent inference occurred, with attributions aligned to the directionality of the essays. The results, consistent with findings from attitude attribution research, suggest that the direction of the essay provides an initial hypothesis of correspondent inference. Subjects may then use their impression of the essay's extremity as a basis upon which to adjust their attribution in accord with the constraint of the position assignment.     

Simple and contingent aftereffects of perceived duration in vision and audition

After repeated presentations of a long inspection tone (800 or 1,000 msec), a test tone of intermediate duration (600 msec) appeared shorter than it would otherwise appear. A short inspection tone (200 or 400 msec) tended to increase the apparent length of the intermediate test tone. Thus, a negative aftereffect of perceived auditory duration occurred, and a similar aftereffect occurred in the visual modality. These aftereffects, each involving a single sensory dimension, aresimple aftereffects. The following procedures producedcontingent aftereffects of perceived duration. A pair of lights, the first short and the second long, was presented repeatedly during an inspection period. When a pair of test lights of intermediate duration was then presented, the first member of the pair appeared longer in relation to the second. A similar aftereffect occurred in the auditory modality. In these latter aftereffects, the perceived duration of a test light or tone is contingent—dependent—on its temporal order, first or second, within a pair of test stimuli. An experiment designed to test the possibility of cross-modal transfer of contingent aftereffects between audition and vision found no significant cross-modal aftereffects.     

The effect of time-out release contingencies on changes in child noncompliance

This project evaluated the effect of time-out release contingencies on changes in child noncompliance to maternal instructions. Twenty-four clinic-referred, noncompliant, preschool children served as subjects. Each child was assessed under baseline conditions and then under one of three experimental conditions: Parent Release, Child Release, or Control. Children in the Parent Release and Child Release conditions experienced time-out contingent upon noncompliance. Temporal and behavioral time-out release contingencies were present in the Parent Release condition but not in the Child Release condition. A spanking procedure was used to inhibit premature escape from time-out for children in the Parent Release group. The results indicated that both time-out groups demonstrated increased compliance ratios. However, improvement associated with the Child Release condition was considered to be clinically insignificant.The authors wish to express their appreciation to Dave DeLawyer, Larry Snapp, and Mike Samac for their assistance in conducting the study.
