Belief similarity and attitude similarity as determinants of interpersonal attraction

It was predicted that attraction would be a function of both attitude similarity and belief similarity, but that attitude similarity would have the greater influence. In Expt I, 60 subjects were presented with strangers that were either similar or dissimilar on attitude and on belief. Attraction was a positive function of both attitude similarity (p < .05) and belief similarity (p < .01). Experiment II replicated and extended Expt I with the addition of a 50% similar group for both attitude and belief. Attraction was a positive linear function of both attitude similarity (p < .001) and belief similarity (p < .02); departure from linearity was not significant. Attitude similarity also had greater effects on other aspects of interpersonal evaluation than belief similarity. The results were discussed in terms of the locus of reinforcement of attitude similarity and of belief similarity.     

Disinhibition of aggression through diffusion of responsibility and dehumanization of victims

The present study tested derivations from social learning theory on the disinhibition of aggression through processes that weaken self-deterring consequences to injurious conduct. Subjects were provided with opportunities to behave punitively under diffused or personalized responsibility toward groups that were characterized in either humanized, neutral, or dehumanized terms. Both dehumanization and lessened personal responsibility enhanced aggressiveness, with dehumanization serving as the more potent disinhibitor. Escalation of aggression under conditions of dehumanization was especially marked when punitiveness was dysfunctional in effecting desired changes. The uniformly low level of aggression directed toward humanized groups, regardless of variations in responsibility and instrumentality of the conduct, attested to the power of humanization to counteract punitiveness. Results of supplementary measures are consistent with the postulated relationship between self-disinhibiting processes and punitiveness. Dehumanization fostered self-absolving justifications that were in turn associated with increased punitiveness. Findings on the internal concomitants of behavior performed under different levels of responsibility suggest that reducing personal responsibility heightens aggressiveness more through social than personal sources of disinhibition.     

The meaning of observed violence: Real vs. fictional violence and consequent effects on aggression and emotional arousal

Sixty male subjects were either attacked or treated neutrally by a confederate, after which each saw a videotape of two men fighting. Subjects were informed that fight was either real or fictitious or were given no explanation of it. Subjects who had previously been attacked and had observed the fight under a set to perceive it as real were subsequently more punitive in their treatment of the confederate than subjects in all other conditions. The combination of prior attack and observation of real violence also sustained blood pressure (BP) at near the level produced by the attack, whereas BP of attacked subjects in the other conditions declined during the time the fight was observed. Palmar sweat measures revealed that observation of real violence was more arousing than observation of fictitious fighting. The results are discussed in terms of the effects that the reality of observed violence has on emotional arousal.     

Irrelevance of mitigating circumstances in retaliatory behavior at high levels of excitation

Subjects were aggressively instigated by a provoker. They then performed either a nonstrenuous or a strenuous task in order to be placed in either a moderate or an extreme state of sympathetic arousal. Following the task, they either learned or did not learn about mitigating circumstances behind the provoker's behavior. This information was received prior to the provision of an opportunity to retaliate. Under conditions of moderate arousal, mitigating circumstances were found to reduce retaliation. In contrast, these circumstances failed to exert any appreciable effect on retaliation under conditions of extreme arousal. In addition, the induction of extreme arousal was observed to increase retaliatory behavior. The findings were considered to support a model of hostility and aggression that postulates a specific interdependency of cognitive and excitatory processes.     

Female preferences for male physiques

A pair comparison design was used to gather information concerning female preferences for male physiques. By independently varying the size of one of four body areas (the arms, upper trunk, lower trunk, or legs), 19 male silhouettes were constructed. Thurstone scale values indicating relative preferences among these silhouettes were generated for each of 64 female subjects. Correlations were calculated between subject variables, e.g., own physical appearance, personal habits, male and female sex-role attitudes, etc., and the underlying preference factors for male physiques. While the bulk of the significant correlations were low, accounting for approximately 5–10% of the variance, the general trend of the results suggest that women's preferences for male physiques can be summarized in terms of feminine and masculine sex-role stereotypes. Women who are traditionally feminine show a preference for traditionally masculine physiques, i.e., tapering V physiques, while less traditional women express more nonstereotyped preferences. It is also suggested that a female's preferences for male physiques may serve as an initial delimiter in narrowing the field of eligibles in heterosexual pairing.     

Discriminability and criterion differences between extraverts and introverts during vigilance

In a signal detection task introverts were better able than extraverts to distinguish between the signal and noise distribution (p < .001) and also set a higher criterion point for their responses (p < .01). The results show that superior vigilance in introverts reported by other investigators is due to two processes.     

Achievement and affiliation motivation in career-oriented and homemaking-oriented college women

The purpose of this research was to investigate the possibility of an interaction between need for achievement and need for affiliation in career-oriented and homemaking-oriented college women. In the first study, scores on the appropriate scales (Achievement and Affiliation) of the Adjective Check List were obtained for 250 female college students, who were also classified as career or homemaking oriented on the basis of their responses to a questionnaire concerning postcollege plans. No significant differences were found between the career- and homemaking-oriented groups on Achievement and Affiliation; but, as predicted, a significant interaction occurred between the two variables. A second study, involving 257 college women and employing the same procedures and analysis, replicated the results of the original study: no main effects, but a significant interaction between Achievement and Affiliation. Implications of the findings for female career development and the counseling of women are discussed.     

The effect of verbal reinforcement on career choice realism

Twenty-four male undergraduates viewed 102 slides containing occupational titles and stated whether or not each represented a realistic career choice. Each subject was given three trials, with the experimental subjects receiving positive verbal reinforcement on the second trial for realistic responses. (If the choice was congruous with the individual's occupational type, as determined by the Vocational Preference Inventory, it was scored as realistic.) The results of the research revealed a tendency for all subjects to increase in career choice realism as a function of participation in the experiment, with significantly (p < .05) more experimental subjects than control subjects demonstrating an operant pattern of responses. Implications of the findings for counselors were discussed.     

The use of the position analysis questionnaire in selecting correlates of job performance among mentally retarded workers

The present study investigated the efficiency of various existing measures, mainly psychological tests, for predicting job performance of mentally retarded workers in a sheltered occupational shop. Twenty-two production-related jobs and one nonproduction-related job were analyzed with the Position Analysis Questionnaire resulting in two job attribute clusters. Correlations between 19 predictor variables and 5 criterion variables, which consisted of supervisor ratings of job performance, were then calculated separately for subjects performing preferred jobs in each attribute group. The results indicated that, contrary to past research, existing measures are predictive of performance on some but not all jobs in a sheltered workshop.     

Stimulus factors and listening strategies in auditory memory: An experimental demonstration

Three experiments are reported in which digits spoken at different rates were recalled and monitored. In Experiment I, digits to be recalled were embedded in varying levels of noise. In Experiment II noise was presented only during the inter-digit intervals, either to the same or to the opposite ear as the digits. In Experiment III Ss monitored these sequences for a specified digit and reported its successor. Stimulus rate and signal-to-noise ratio affected perceptual processing time, as evidenced by the frequency and relative proportion of item and order errors. These stimulus factors induce listening strategies that influence the shape of the serial position curve and that persist after stimulus conditions are changed. The data are consistent with a two-stage processing model for the temporal course of speech perception and the nature of listening strategies.
