While previous research has indicated that certain situational variables can mediate the typical positive relationship between attitudinal similarity and attraction, investigations focusing on the impact of individual difference variables on this relationship have typically yielded unimpressive results. The present experiment was conducted to test the prediction that individual differences in sensation seeking do moderate this relationship. The major results showed that, as predicted, high sensation seekers were more attracted than low sensation seekers to dissimilar others, whereas low sensation seekers were more attracted than high sensation seekers to people with similar attitudes. The data also indicated that a misattribution of arousal manipulation serves to increase attraction under certain conditions. Specifically, misattribution of aversive arousal increased low sensation seekers' attraction to a dissimilar stranger and increased high sensation seekers' attraction to a similar stranger.  相似文献

Ninety-six first graders were given a list of either words or pictures to process under three types of incidental orienting instructions (semantic, directed at list organization; semantic, directed at individual item characteristics; and physical) and an intentional-learning instruction. For pictures and words, list organizational instructions were the most effective, and were superior to intentional-learning instructions. In contrast, individual item-orienting instructions were not better than intentional-learning instructions on either list. Additionally, different patterns of instructional effects emerged on the two list types, which were interpreted with respect to both available data and contemporary processing theories.  相似文献

In the research paradigm known as effort justification, people engage in an effortful activity in order to attain a goal. As a result, the goal becomes more attractive. Two experiments were conducted to test the notion that the effort justification sequence can account for the positive changes that result from psychotherapy. In the first experiment, subjects who were afraid to approach a snake underwent one of two types of effortful therapy. One was a modified form of an anxiety-producing therapy known as “implosive therapy”; the other was merely a set of physical exercises. It was reasoned, on the basis of cognitive dissonance theory, that the expenditure of effort would lead to a positive change in the ability to approach the snake but only under conditions of high decision freedom. Half of the subjects in each of the therapy conditions participated with high choice; the other half with low choice. Subjects' improvement in their approach to snakes was assessed. A main effect for decision freedom was predicted and found independently of the type of effort that subjects expended. A second experiment conceptually replicated the findings of the first experiment. Subjects who wanted to become more assertive participated in an effortful, physical exercise therapy or in a modified form of the standard treatment for fear of assertiveness. The results of the 2 × 2 factorial experiment again showed a main effect for decision freedom such that high choice subjects became more assertive. The findings were discussed in terms of dissonance and attribution theories as well as for implications for future consideration of psychotherapy.  相似文献

The disappearance characteristics of luminous designs were studied in three experiments. The stimuli were geometric forms set off by either real or subjective contours. Subjective-contour forms fragmented more often and in a manner qualitatively different from that of forms created with real contours. Previewing a real-contour form increased the subsequent fragmentation of that form, but no adaptation effects were noted among forms created with subjective contours, and there was no cross-contour adaptation. These results are interpreted as inconsistent with the position that subjective contours result from the partial activation of feature-analyzer mechanisms in the visual system.  相似文献

Two experiments were performed that investigated attitudinal influences on cognitive categorization. The studies assessed categorization as a dynamic process with a multiple-sort (MS) technique, having Ss recategorize sentences unti! they ran out of meaningful categories. Condition I allowed Ss to use any dimensions they chose, and Condition It imposed the restraint of the “favorable-unfavorable” dimension. No effects of involvement were found when unrestricted sorting was allowed but were found when the evaluative dimension was imposed. There appeared to be a tendency for attitudinal involvement to maintain complexity across sorts. Results were discussed in terms of the influence of dimensions and the possible effects of certain stimulus properties on the maintenance of categorization complexity.  相似文献

Following the presentation of a single list of word pairs consisting of a three-letter word on the left and a five-letter word on the right, groups of 64 Ss each were asked to recall the (a) three-letter words, (b) five-letter words, (c) intact pairs, or (d) five-letter words with the three-letter words provided. Two types of repeated pairs were presented, one in which the same three- and five-letter words were repeated together (same pairs) and one in which the same five-letter word was repeated with different three-letter words (different pairs). For half of the Ss in each recall group, the repetitions of a pair containing a given five-letter word were massed (MP); for the other half, the repetitions were distributed (DP). Recall of MP same pairs and the eomponents of these pairs was consistently poorer than that of DP same pairs. Recall of the repeated component of the different pairs was also poorer under MP than under DP. The results were interpreted as supportive of an attenuation-of-attention explanation of the spacing effect.  相似文献

An inexpensive turntable for producing uniform angular accelerations for use in vestibular research is described. The table provides semicircular canal stimulation for cats or smaller animals at moderate accelerations above 3 deg sec?2. A head restraint suitable for use on the table and designed for chronically implanted cats is also described.  相似文献
