Assumed Similarity of Attitudes About AIDS Among Gay and Heterosexual Physicians

Heterosexual and gay physicians indicated their own attitudes on several issues related to the AIDS epidemic and attributed a position on each issue to the target group "most people." The heterosexual physicians' attitudes were more negative than the gay physicians' attitudes. Both groups judged that "most people" hold attitudes more negative than their own. The distance between own and attributed position as much greater for the gay individuals. This distance effect was due primarily to differences in self-ratings between the two groups. Own and attributed position correlated positively for each group of physiaans. Additionally, the tendency to assume similarity was marginally stronger for heterosexuals with high than low homophobia. Theoretical interpretation is presented.     

A microprocessor-(Heath ET-3400) based backup control system for laboratory experiments

This paper describes a psychology laboratory experimental control system that utilizes a PDP-11/10 minicomputer to perform both instrument control and data acquisition functions. The minicomputer is backed up by a Heath ET-3400 microprocessor trainer system which performs control functions only. Major components of the hardware and software comprising This system are described.     

Toward operationalizing a psychoeducational definition of learning disabilities

An operational definition of “learning disabilities” is presented from the standpoint that classificatory psychoeducational definitions must ultimately relate to educational processes. Thus the condition should be described in terms of abilities crucial to educational achievement, and noneducational criteria should not be employed. It is pointed out that the most generally accepted current definition — which identifies children as “learning-disabled” on the basis of behavioral criteria, while excluding others because of etiological and other nonbehavioral factors — overlooks functional similarities among such groups as educable mentally retarded and emotionally disturbed children. These similarities warrant the inclusion under the rubric of “learning-disabled” of some children who may also be grouped within other diagnostic categories. Consequently, the profferred definition is based on a primary concern with day-to-day learning and management issues. Concepts subtended by the definition are operationally defined, and its relationship to programming is discussed.     

Female aggression as a function of attitudes toward women

The aggressive behavior of female subjects who held either liberal or traditional beliefs concerning the role of women in modern society was investigated as a function of provocation by traditional or liberal male opponents. Traditional female subjects responded more aggressively than liberal females. The male opponent's attitude had no effect on female aggression.This article is based on an honors thesis submitted to the Honors and Experimental College of Kent State University by the second author.     

Is BodyThink an efficacious body image and self-esteem program? A controlled evaluation with adolescents

This study aimed to evaluate the efficacy of BodyThink, a widely disseminated body image and self-esteem program. Participants were 277, grade 7 students from 4 secondary schools in Australia. The intervention group (62 girls, 85 boys) participated in BodyThink during four 50-min lessons, while the control group (65 girls, 65 boys) received their usual classes. All participants completed baseline, postintervention and 3-month follow-up questionnaires. For girls, the intervention group reported higher media literacy and lower internalization of the thin ideal compared to the control group. For boys, the intervention group reported higher media literacy and body satisfaction than the control group. Although some positive outcomes were observed, it would be valuable to find ways to enhance the impact of BodyThink, especially in light of its wide dissemination. Suggestions for improving BodyThink are presented.     

Rephrasing between Disjunctives and Conditionals: Mental Models and the Effects of Thematic Content

Two experiments are reported thatinvestigate whether the logical equivalence of conditionals and disjunctives is paralleled by a psychological equivalence. In these experiments, subjects rephrased from one form into the other. Experiment 1 demonstrated strong effects of familiarity and causality of rule content. Similar findings were found in Experiment 2 with a different conditional rule syntax. An account of the experiments is given in terms of mental models theory: In this account, task performance can be seen to depend upon the extent to which the model sets used by subjects to generate rephrasings are complete, task content being the most important factor affecting model set completion. A 'Minimal Completion' strategy is proposed to operate in the absence of thematic content. The experiments also falsify the long-held assumption that conditionals with negative antecedents are always interpreted as their disjunctive equivalents. This raises doubts about the mental models explanation for matching bias in conditional reasoning.     

A randomized controlled trial of the effect of D-cycloserine on extinction and fear conditioning in humans

Previous research has shown that D-cycloserine (DCS) facilitates extinction of Pavlovian fear conditioning in rats and enhances exposure therapy in humans. The aim of this study was to test the effect of DCS on extinction of fear conditioning in humans. In three experiments, 238 participants were given either DCS (50 or 500 mg) or placebo 2-3 h before extinction training following a differential shock conditioning paradigm. Clear extinction and recovery (return of fear) effects were observed on both skin conductance and self-reported shock expectancy measures in three studies. DCS had no influence on these effects. The same pattern was observed when the analysis was restricted to aware participants or to good conditioners, when fear-relevant cues (pictures of snakes) were used as the conditioned stimuli, or when analysis was restricted to heightened snake-fearful participants. These results suggest that DCS may not enhance the extinction, or prevent the recovery, of learned fear in a differential Pavlovian conditioning paradigm in humans. Further experimental research is needed to better understand the mechanisms underlying the therapeutic effects of DCS.     

The public's perception of psychotherapy and counseling: Differential views on the effectiveness of psychologists,psychiatrists, and other providers

This study examined the public's perceptions relative to the effectiveness of psychotherapy and counseling, expectations of treatment efficacy for different psychotherapy and counseling providers (i.e., clinical psychologists, counseling psychologists, counselors, general medical practitioners, marital and family therapists, psychiatrists, self-help groups, and social workers), professional characteristics, and factors that may influence treatment utilization in an adult population. The sample viewed psychotherapy or counseling as moderately effective and perceived psychotherapy/counseling to be effective for 26 to 50 percent of all cases. The perceived amount of time necessary for noticeable improvement in psychotherapy or counseling was approximately four months, and the expected necessary length of treatment was approximately eight months. Participants stated they were moderately willing to seek psychotherapy or counseling if they were to experience a mental problem, and reported discernible differences among the eight psychotherapy/counseling providers in terms of treatment efficacy. Differences were also found in the relative perception of providers' personal/professional qualities and characteristics.     

Infants learn about objects from statistics and people

In laboratory experiments, infants are sensitive to patterns of visual features that co-occur (e.g., Fiser & Aslin, 2002). Once infants learn the statistical regularities, however, what do they do with that knowledge? Moreover, which patterns do infants learn in the cluttered world outside of the laboratory? Across 4 experiments, we show that 9-month-olds use this sensitivity to make inferences about object properties. In Experiment 1, 9-month-old infants expected co-occurring visual features to remain fused (i.e., infants looked longer when co-occurring features split apart than when they stayed together). Forming such expectations can help identify integral object parts for object individuation, recognition, and categorization. In Experiment 2, we increased the task difficulty by presenting the test stimuli simultaneously with a different spatial layout from the familiarization trials to provide a more ecologically valid condition. Infants did not make similar inferences in this more distracting test condition. However, Experiment 3 showed that a social cue did allow inferences in this more difficult test condition, and Experiment 4 showed that social cues helped infants choose patterns among distractor patterns during learning as well as during test. These findings suggest that infants can use feature co-occurrence to learn about objects and that social cues shape such foundational learning in distraction-filled environments.     

Serious misapplications of military research: dysfunction between conception and implementation

Researchers and technologists involved in the development of weapon systems can take their work to such extremes as to cause unplanned injury or death to others and lasting damage to the environment, reviewed here. In some cases innocent human casualties and ecological harm may actually be programmed and achieved. An analysis is proffered, attributing blame, and indicating efforts to correct the situation. The ethics involved are “complexified”, moral boundaries are exceeded, and humanity is transgressed as it develops solutions to the problem. The license to make mistakes becomes more limited with the passing of the years... Primo Levi, chemist¹ To use the term coined in 1994 by John L. Casti of the Santa Fe Institute.
