The attribution of arousal and emergency helping: A bidirectional process

J. M. Piliavin, J. A. Piliavin, and J. Rodin (1969, Journal of Personality and Social Psychology, 13, 289–299) and J. A. Piliavin, J. F. Dovidio, S. L. Gaertner, and R. Clark (1981, Emergency intervention, New York, Academic Press) proposed that physiological arousal is causally related to a bystander's response to an emergency. Examining this proposition, the current research investigated the hypothesis that residual arousal from an extraneous event has the capacity to facilitate as well as to inhibit bystander intervention during an emergency depending on whether the extraneous arousal is attributed to the emergency or whether the emergency-generated arousal is attributed to the extraneous event. Specifically, it was predicted that during an Unambiguous emergency, extraneous arousal from the prior performance of physical exercise would be attributed to the emergency and thus facilitate bystander responsiveness. During an Ambiguous emergency, however, emergency-generated arousal would be attributed to the prior performance of physical exercise and thus bystander responsiveness would be inhibited by higher levels of arousal. Fifty-four male subects performed no, moderate, or high levels of exercise before exposure to an Unambiguous or Ambiguous emergency. Results indicated that during the Unambiguous emergency, higher levels of prior exercise facilitated helping. However, when the emergency was Ambiguous, high levels of exercise tended to inhibit bystander responsiveness. Correlational analysis of telemetered heart rates and latency to intervene corroborated the above pattern of findings.     

Making Life Complicated: Prompting the Use of Integratively Complex Thinking

ABSTRACT Two studies are reported which assess the proclivity of individuals to increase the integrative complexity of social, moral, or religious thinking when prompted to do so. We also examined the influence on complexity of topic area and respondents' religiosity. In both studies significant increases in complexity were obtained when participants were prompted to differentiate and integrate material, suggesting that an important distinction needs to be made between competence and performance with respect to complexity. However, there was some evidence that prompting complexity was more effective in eliciting differentiation than integration. Both studies indicated that overall, religious orientation was not a significant predictor of integrative complexity, nor did it interact with other factors (including religious vs. nonreligious content of stimulus materials). Finally, there was some evidence that complexity may vary across different content areas, and this variation may be differentially affected by prompting for complexity.     

Effects of Impressions of Amazement and Foolishness on Compliance

Impression management theory maintains that the use of strategic tactics such as self-promotion can influence targets in desired directions. Self-promotion concerns an actor's attempts to establish an image of competence. In this study, a confederate attempted to sell raffle tickets to targets after promoting himself by amazing his targets with his extraordinary calculating skills (high competence), making a fool of himself by exhibiting calculating skills falling far short of pretensions (low competence), or making no impression at all. Amazing targets was achieved by communicating with the experimenter using a concealed communications device. It was found that amazement increased compliance substantially over foolishness and making no impression, while foolishness yielded the same degree of compliance as making no impression. Thus, the utility of self-promotion in influencing others, as predicted by impression management theory, received empirical support.     

The Impact of Contemplated Exposure to a Survivor of Rape on Attitudes toward Rape1

Male and female college students were asked to rate the truth of myths about rape either before or after contemplating how they would react if a close friend or relative told them she had been raped. It was expected that such contemplation would decrease endorsement of rape myths, by increasing sympathy for victims and reducing the tendency to blame victims for sexual assault. Typically, studies have found that women are less accepting of rape myths and more sympathetic to rape victims than men. A reason for this may be that women have thought about rape more and are more likely to have experienced sexual assault or to be acquainted with a survivor. Based on the above findings, it was hypothesized that contemplating exposure to a rape survivor would be particularly beneficial to men's attitudes. Results contradicted the hypothesis and showed that contemplating exposure increased rejection of rape myths for women but slightly increased men's endorsements. In contrast, men and women who were actually acquainted with a rape survivor rejected rape myths more strongly than those who did not claim acquaintance.     

Attention deficit disorder in reading-disabled twins: Evidence for a genetic etiology

In order to assess the genetic etiology of attention deficit hyperactivity disorder (ADHD), the basic regression model for the analysis of selected twin data (DeFries & Fulker, 1985, 1988) was fitted to questionnaire data (DICA: Diagnostic Interview for Children and Adolescents; Herjanic, Campbell, & Reich, 1982) for 37 identical and 37 fraternal twin pairs tested in the Colorado Reading Project. Results of this analysis suggest that ADHD is highly heritable. Moreover, adjusting DICA scores for either IQ or reading performance differences did not substantially change parameter estimates. In future analyses of larger data sets, distinguishing between possible subtypes of attentional problems (e.g., ADD with or without hyperactivity) may facilitate tests of more searching etiological questions.This work was supported in part by program project and center grants from NICHD (HD-11681 and HD-27802) to J. C. DeFries. This report was prepared while J. Gillis was supported by NIMH training grant MH-16880, and J.

Anticipation of reward omission as a cue for choice behavior

A within-subject partial reinforcement extinction effect was obtained in a conditional discriminative choice task. In choice acquisition, one group had learned a task in which one choice alternative was continuously reinforced (CRF) and the other alternative was partially reinforced (PRF). Most errors in the acquisition phase were the choosing of the CRF lever when the conditional stimulus signaled the PRF lever; in extinction this pattern of choice errors reversed. In extinction, most errors were choosing of the PRF lever when the conditional stimulus signaled the CRF lever. The predictions of frustration theory and sequential theory were compared with the choice data. The results were interpreted as consistent with the anticipatory frustration construct within an associative mediational theory.     

Factor comparison of two Minnesota Multiphasic Personality Inventory short forms

A sample of 315 valid Minnesota Multiphasic Personality Inventory (MMPI) protocols were selected from inpatient files and scored for both the MMPI-168 and Faschingbauer Abbreviated MMPI short forms. Each short form was then factor-analyzed by a principal axis strategy with varimax rotation. The six factors extracted from each short form were then compared as to their similarity by use of the s index. This procedure showed five of the six factors in each short form as having a significant relationship of the pattern of salient variables they had in common with the complimentary factors of the other form. These data suggest that both short forms, though based on different construction methodologies, share the same underlying personality attributes. Future research is suggested to replicate these results and extend them to the full MMPI.     

Personality profiles at various levels of athletic participation

Various grades of athletes (265 male and 134 female) were administered the German version of the EPQ. The entire group was characterized by being more extraverted and less neurotic (compared to population norms); sex differences were exhibited, female profiles being higher on emotionality and lower on Psychoticism (tough-mindedness) with no significant difference being observed in mean Extraversion scores. When grouped in terms of ‘level of competitive involvement’, top-class male athletes were shown to be significantly more tough-minded and less stable than middle- or lower-class participants, an almost opposite trend being found in females, where top athletes were liable to be more extraverted, less neurotic and less aggressive and tough-minded than the other classes.
