Romantic Emotional Attachment: Additional Factors in the Development of the Sexual Orientation of Men

This retrospective study compared reports of gay and heterosexual male college students about particular behaviors and feelings during childhood and adolescence. The results were interpreted as providing general support for Bell's heterogamy principle that regardless of a person's sexual orientation, his or her romantic attachments will be to people perceived different from themselves.     

Ambivalence and Response Amplification Toward Native Peoples1

This study determined whether ambivalence toward Native peoples would result in amplified, or polarized, responses to members of the group, as assessed in terms of both general attitudes and social policy endorsements. In addition, it examined whether priming would mediate these effects, based on the notion that ambivalent attitudes contain both positive and negative dimensions that may be activated at different times. Induction of different mood states was used as an indirect priming manipulation. One hundred thirty-eight Canadian participants completed measures of ambivalence toward Native peoples and Canadians. One week later, these participants underwent a positive, neutral, or negative mood induction procedure. They then indicated their attitudes toward Native peoples and Canadians, and responded to social policy questions involving both groups. Participants who were highly ambivalent or not ambivalent toward Native peoples were retained for analysis; participants generally displayed low ambivalence toward Canadians. It was predicted and the results confirmed that only participants who were ambivalent toward Native peoples would display a relative response amplification effect: a greater difference between positive and negative mood states in their responses to Native peoples than in their responses to Canadians.     

Environmental concern and cooperative-competitive behavior in a simulated commons dilemma.

Commons-dilemma simulation games are designed to examine behavior associated with preservation and destruction of slowly regenerating natural resources. In Experiment 1, 120 introductory psychology students in the United States were assigned to high- or low-environmental-concern conditions based on a median split of their scores from a pretest. They then played either a points game, in which they selected numerical points from a slowly regenerating pool, or a tree game, in which they harvested trees from a jointly managed forest. After the game, subjects were asked to sign a petition for an environmental cause, to participate in a litter pick-up, and to participate in a recycling drive. Neither environmental concern nor proenvironmental behaviors were related to commons dilemma performance. In Experiment 2, 57 other introductory psychology students were assessed on environmental concern and Machiavellian personality, size of other players' harvesting choices, and other players' altruistic choices, all correlated with subjects' outcomes in the game. Overall, cooperation and competition were more important than environmental concern in predicting behavior in the commons dilemma simulation game.     

Reducing Avoidance of Social Interaction with a Physically Disabled Person by Mentioning the Disability Following a Request for Aid1

The effectiveness of strategies for reducing avoidance of social interaction with a physically disabled person was experimentally investigated. Female college students privately expressed their preference for social interaction before and after learning the other was a female in a wheelchair or nondisabled. The results provide evidence for the effectiveness of mentioning the disability following a request for aid related to the disability (the Request-mention Strategy). Change in preference for social interaction was more positive when the disabled person employed the Request-mention strategy than when she said nothing. Requesting aid without mentioning the disability was not found to be effective. A request for aid unrelated to the disability was clearly ineffective. The disabled person who said nothing was avoided, in comparison to when the same person was nondisabled. Favorability of impressions of the other, as measured by ratings of her characteristics, was not influenced by the experimental conditions.     

Aggression and heat: the influence of ambient temperature, negative affect, and a cooling drink on physical aggression.

Two experiments were conducted to examine the influence of ambient temperature upon physical aggression. In the first, male subjects received either a positive or negative evaluation from a confederate and were then provided with an opportunity to agress against this person by means of electric shock. On the basis of previous research, it was predicted that high ambient temperatures (92-95 degrees F) would facilitate aggression by those receiving positive evaluations but actually inhibit such behavior by those receiving negative assessments. Results confirmed both of these predictions and also indicated that more moderate but still uncomfortably warm temperatures (82-85 degrees F) produced similar effects. The second experiment employed procedures similar to the first and examined the suggestion that administration of a cooling drink would reduce the impact of high ambient temperatures upon overt aggression. This prediction, too, was confirmed. The possible mediating role of negative affect with respect to the influence of ambient temperature and other environmental factors upon aggression was discussed.     

On the relation between visual surround and motion aftereffect velocity

Two experiments examined the effect of changes in the visual surround upon the velocity of motion aftereffects. Experiment I showed that introduction or reintroduction of a patterned surround midway through the test period was sufficient to produce an increase in apparent velocity. However, a greater increase was observed when a patterned surround instead of a dark homogeneous surround had been used during the induction period. Experiment II demonstrated that luminance change was also sufficient to produce an increase in apparent velocity, although the extent of the increase was not as great as that produced through the use of the patterned surround in Experiment I. These results indicate that a change in stimulus surround is sufficient to produce an increase in the velocity of a motion aftereffect and that the extent of the increase is dependent upon the characteristics of both the induction and test surrounds.     

Behavioral assessment of eating patterns and blood glucose in diabetes using the Self-Monitoring Analysis System

The Self-Monitoring Analysis System is a set of microcomputer programs that were developed to remove clinical judgment from the task of behavioral assessment using self-monitoring diaries. The program is written in Turbo Pascal and runs on MS-DOS (16-bit) or CP/M (8-bit) microcomputer systems. The program allows the user to custom design data bases with hundreds of binary, categorical, integral, and real variables. Full-screen data-entry forms can be custom designed, and random access files allow for flexible data entry and editing. The program makes extensive utilization of Pascal’s very flexible data structure capabilities. Dynamic allocation of memory allows the program to maximize its use of available RAM. Data from a patient with diabetes is presented as a case study illustrating the system’s utility.     

Trivial persuasion in the courtroom: the power of (a few) minor details

Investigated the influence of trivial testimonial detail on judgments of 424 undergraduates who served as mock jurors. Ss read a summary of a court case involving robbery and murder. In Experiment 1, detailed testimony influenced judgments of guilt, even when the detail was unrelated to the culprit. In Experiment 2, detailed testimony was especially powerful when an opposing witness testified that she could not remember the trivial details. Subsequent analyses suggest that the impact of detailed testimony on guilt judgments is mediated by inferences about the eyewitnesses. When eyewitnesses provided more detail, they were generally judged to be more credible, to have a better memory for the culprit's face and for details, and to have paid more attention to the culprit.
