Sixty-four undergraduate males received either very postive or very negative personal evaluations from an attitudinally similar or dissimilar stranger, and were then given an opportunity to aggress against this person by means of electric shock. Half were exposed to these stimuli under comfortably cool environmental conditions, while half were so treated under uncomfortably hot conditions. It was predicted that aggression toward the victim would increase as the degree of negative affect induced among subjects by the experimental conditions increased up to moderate levels, but that beyond this point, further increments in negative affect would actually tend to inhibit such behavior. A significant (p < .007) curvilinear relationship between negative affect and aggression supported these predictions, and suggested that such affect mediates the influence of high ambient temperatures on human aggression. 相似文献

To investigate the Miller-Dollard hypothesis (Social learning and imitation, New Haven: Yale University Press, 1941) that verbal labels increase distinctiveness of cues, generalization gradients to pure tones were obtained before and after label training. One group was trained to label all seven tones in an array and another only the middle tone. Three additional groups controlled for nonverbal factors. Before training, gradients were characterized by progressive loss of stimulus control with exposure to the generalization test stimuli. The main effect of possession of labels was to retard this loss, but only in tests where S+ was a labeled stimulus. While the specificity of label effects was in line with the Miller-Dollard hypothesis, the finding that labels did not confer a clear advantage at the start of testing was not. It was suggested that the unlabeled stimuli may have been sufficiently distinct to mask label effects and that interference generated by the test stimuli reduced distinctiveness to levels needed for such effects to emerge. 相似文献

Several phenomena in the acquisition of word meanings may be accounted for by a theory of component-by-component acquisition, a mechanism analogous to that proposed for phonological development. By defining a concept as an habitual plan, and a component as a subplan, we may extend this theory to acquisition of concepts in general. This theory may be applied to logical concepts, physical reasoning and moral reasoning as well as verbal concepts. The ideas of component-by-component acquisition and of transfer of learning between concepts sharing components thus provide an alternative to developmental stage theories. 相似文献

Aggression and heat: mediating effects of prior provocation and exposure to an aggressive model. 总被引:1,自引:0,他引:1
Sixty-four undergraduate males participated in an experiment designed to examine the effects of level of prior anger arousal, exposure to an aggressive model, and ambient temperature on physical aggression. On the basis of Bandura's social learning theory of aggression, it was predicted that uncomfortably hot environmental conditions would be most effective in facilitating later aggression when subjects had both witnessed the actions of the model and been exposed to strong provocation from the victim, but least effective in this regard when they had neither witnessed the actions of the model nor been exposed to prior instigation. In contrast to these predictions, results indicated that high ambient temperatures facilitated aggression by nonangered subjects but actually inhibited such behavior by those who had previously been provoked. 相似文献

Storms and Nisbett found that insomniacs got to sleep faster than usual on nights when they took placebos believed to be arousal pills. Our study attempted: (a) to replicate the reverse placebo effect using a method of measurement considered more accurate than the original technique, (b) to evaluate the effect of an arousal pill therapy after therapy is discontinued, and (c) to clarify which of two hypotheses better accounts for the effect. Using 42 insomniacs, the design varied whether pills were administered (pill) or withheld (no pill) and whether or not high justification was provided for taking the pills. The high-justification-pill and the high-justification-no-pill groups were given information intended to justify their participation, while the no-justification-pill and no-pill-no-justification groups were treated like the original arousal and control groups. Instead of a decrease in latency to sleep, the no-justification-pill group but not the high-justification-pill troup displayed a typical placebo reaction on nights they took the pills. Our results cast suspicion on the original finding. The lack of response by the high-justification-pill group is discussed in terms of Bem and Kelley's views of attribution theory. 相似文献

The behaviors of rats selectively bred for either good or poor shuttle box avoidance learning were studied. The results of Experiment 1 indicated that the phenotypic difference in avoidance learning is not associated with differences in speed of escape or avoidance responding. Differences between the lines in frequency of intertrial responses (ITRs), which appear during training but not during pretest, suggest that ITRs in animals of the low-avoidance (SLA) line are more suppressed by electric shock than in animals of the high-avoidance (SHA) line. This result suggests that SLA animals may be more emotionally responsive than SHA animals. Experiment 2 demonstrated that the animals of the two lines do not differ in absolute sensitivity to electric shock, and Experiment 3 showed that the poor performance of the SLA line is not due to an inability to learn. Experiment 3 also provided evidence which suggests that the poor avoidance learning by SLA animals is due to their emotional reactivity. Observations of open-field behavior in Experiment 4 are consistent with this hypothesis. The major consistent correlate of the phenotypic difference in avoidance learning is greater emotionality or emotional reactivity in SLA than in SHA animals. 相似文献

Recently, Loftus and her associates have demonstrated that the ability of subjects to respond accurately to questioning about an event they witnessed can be systematically imparied by the interposition of misleading questions between exposure to the event and assessment of accuracy. One explanation for this low eyewitness accuracy is that it is due to demand characteristics created by the misleading questions. The present study addresses this issue using a modification of the paradigm developed by Loftus, Miller, and Burns (1978). The results indicate that even when the final accuracy test does not easily allow subjects to accede to demand pressure, significant impairment of eyewitness accuracy is still obtained. Since this lowered accuracy does not seem due to simple compliance to demand pressure, it suggests that misleading questions do in fact interfere with subsequent eyewitness accuracy. 相似文献

Male and female undergraduates interacted with a same-sex experimenter and a same-sex assistant of the experimenter. Either the experimenter or the assistant smoked. Subjects were provoked or not provoked by the experimenter and then smoked. Subjects were provoked or not provided by the experimenter and then provided with an opportunity to treat him or her in a hostile manner. Additionally, subjects were classified as smokers or nonsmokers and as supporting or opposing smoking in public places. Tobacco smoke was found to facilitate hostile behavior whether or not subjects were independently annoyed and whether or not it originated from the annoyer or a bystander. No sex differences were observed in this effect. Also, no appreciable difference was observed in the hostile behavior of smokers and nonsmokers. Persons opposed to public smoking reacted more strongly to the provocation than persons supportive of public smoking, but this effect was independent of the presence or absence of smoke. 相似文献
