The literature concerning the controversy between dissonance and selfperception theories is reviewed. It is proposed that the two theories be regarded not as “competing” formulations but as complementary ones and, furthermore, that each theory is applicable only to its own specialized domain. Self-perception theory, it is suggested, accurately characterizes attitude change phenomena in the context of attitude-congruent behavior and dissonance theory attitude change in the context of attitude-discrepant behavior. Attitude-congruent is defined as any position within an individual's latitude of acceptance; attitude-discrepant as any position in the latitude of rejection. An experimental test of these notions produced confirming evidence. Subjects who were given an opportunity to misattribute any potential dissonance arousal to an external stimulus did not change their attitudes, relative to low choice subjects, if they were committed to endorsing a position in their latitude of rejection. If the commitment concerned a position in the latitude of acceptance, however, these subjects did exhibit attitude change relative to low choice subjects. 相似文献

Hamilton and Zanna (Journal of Personality and Social Psychology, 1974, 29, 649–654) demonstrated that the meaning of an attribute as rated on connotatively related scales changed as a function of context desirability. This finding was viewed as supporting a meaning change interpretation of context effects in impression formation. Kaplan (Memory and Cognition, 1975, 3, 375–380, Exp. 1) found that similar changes also occurred on scales unrelated in meaning to the test attribute and argued that changes on both kinds of scales were due to halo effects produced by the contexts. Controlling for possible scaling artifacts, the first experiment reported here showed that substantially greater changes occurred on related than on unrelated scales. Kaplan (1975, Exp. 2) also found that the magnitude of context-induced differences in judgments of trait likability was not increased by creating contexts denotatively related to the test attributes. Adding measures of connotative meaning, the second experiment in this paper showed that substantially greater context-induced changes did occur on related meaning scales and, in contrast to Kaplan, on trait likability for the denotatively related contexts. The results of each experiment are consistent with a meaning change position but would not be expected on the basis of the halo effects model. 相似文献

Two experiments investigated the relationship between social influence and the number of persons attempting influence. The organization of these persons was varied so that subjects either perceived them as a single group, as several distinct groups, or as an aggregate of unrelated individuals. Conformity was found to increase as the number of separate individuals and groups (distinct social entities) in opposition increased. But varying the size of a single group had little effect on subjects' level of conformity. Furthermore, even when subjects had a partner (social supporter), they conformed more when the opposition was categorized as several entities than as a single group. Overall, findings from the studies suggest that the manner in which persons are initially organized into groups and aggregates of individuals affects their persuasive impact on observers. Implications of these findings for research on social influence were considered. 相似文献

This study varied both the intrinsic and extrinsic rewards associated with performing a task in a risk taking situation. When the task performed to win a prize provided little if any intrinsic reward, subjects liked and tried for prizes that were easy to obtain. In contrast, when the task was intrinsically rewarding, subjects liked and tried for those prizes that were somewhat more difficult to obtain. In addition, subjects were more likely to like and try for prizes easier to obtain when the extrinsic reward was high. 相似文献

Different factors may affect reciprocity and attraction to an aid-giver. Sixty white South African high school students participated in a “record contest”. Hints provided by the quizmaster enabled them to win a prize. His help was expected or unexpected and, in providing this help, the quizmaster either did or did not violate a specific norm against doing so. It was predicted that recipients of unexpected help would display more reciprocity than recipients of expected help, but that the aid-giver would be derogated only when he behaved in both an unexpected and counternormative way and that, in general, attraction and reciprocity would be unrelated. These hypotheses were supported. They suggest that reciprocity is normally not mediated by attraction and that neither expectancy violation nor counternormative behavior will be itself produce derogation of an aid-giver. They further suggest recipients of unexpected help probably feel more obliged to repay an aid-giver than do recipients of expected help. 相似文献

An experimental analysis of social traps 总被引:2,自引:0,他引:2
Kevin C. Brechner 《Journal of experimental social psychology》1977,13(6):552-564
Social traps, such as the overgrazing of pasturelands, overpopulation, and the extinction of species, are situations where individuals in a group respond for their own advantage in a manner damaging to the group. A laboratory analog was devised to simulate conditions that produce social traps. The traps were constructed by superimposing schedules of reinforcement. Single responses were followed by multiple consequences which were opposite in valence, with the negative consequence delayed. Subjects in groups of three could respond individually for points that applied toward class credit. Each ten presses of a button added one point to the subject's total and subtracted one point from a common pool. The pool was replenished with points at fixed rates. If subjects responded for points faster than the replenishment rates, the pool would empty and the experiment would terminate before subjects could accumulate maximum credit. In addition, the maximum pool size and the ability to communicate were varied. Main effects were found for both, which indicated the least effective resource management occurred when the pool was small and no communication allowed. An analysis of cumulative records showed differing response patterns across conditions. 相似文献

Rats were trained in an operant discrimination involving two panel lights, A and B. Group CI (Conditioned Inhibition) was trained to lever press in the presence of A (S+), and not in the presence of the compound AB (S?). The opposite contingencies held in Group CE (Conditioned Excitation). Response rates were higher in Group CE than in Group CI, especially to the positive stimulus. However, the groups acquired the discrimination at comparable rates. In a separate phase of the experiment, a tone (C) was separately trained in the absence of the lights to control responding. All seven possible combinations of A, B, and C were then presented randomly during extinction. The inhibitory effect of B on C in Group CI was comparable in magnitude to the excitatory effect of B on C in Group CE. B's effect on C was not altered by the presence or absence of A, regardless of whether A was inhibitory or excitatory. The symmetry between CI and CE revealed by the stimulus-compounding test may be partly artifactual. 相似文献

Two groups of food-deprived rats responded for access to liquid reinforcers on a wide range of concurrent variable-interval schedules. During the first part of the experiment, one group chose between two different sucrose solutions; for a second group, the choice involved a sucrose solution and a solution of condensed milk. In the latter part of the experiment, the two groups chose between identical sucrose solutions. A variety of multivariate equations were applied to data obtained from both conditions. The best-fitting equation proved to be a multivariate power function, which is an extension of Herrnstein's basic matching law. 相似文献

After receiving a sample shock, subjects in a Threat Condition were told that they would receive additional painful shocks while subjects in a Nonthreat Condition were not threatened with additional shocks. Subjects in an Attentional Diversion Condition were then instructed to read and think about an amusing story, subjects in a Situation Redefinition Condition were instructed to write down reasons why they should not be afraid in this situation, and subjects in a Control Condition were not given any instructions for coping with stress. (Coping Conditions were factorially crossed with Threat Conditions and 192 subjects were employed.) Physiological measures (pulse rate, finger pulse volume, skin resistance) indicated that unlike the results of previous research, attentional diversion was effective in reducing stress but situation redefinition was not. Discussion was focused on the parameters which determine whether or not a coping strategy will be effective. 相似文献

Recent studies on information processing have developed an alternative model of mental abilities which constitutes an integration of Russian clinical research and North American factor analytic research. This model proposes that information may be processed in a simultaneous synthesis or a successive synthesis. The present study examines variations in these syntheses in three intelligence groups in order to identify the types of information processing characteristic of different intelligence groups. A stratified sampling of verbal and nonverbal IQ was used to select 60 boys of age 9–10 in each of three verbal IQ ranges: 71–90, 91–110, and 111–130. A battery of tests used in previous research was administered to all subjects. Multivariate analyses of variance and discriminant analyses indicated that the IQ groups differed markedly on tests used to identify simultaneous synthesis, most notably Raven's Progressive Matrices, and differed slightly less on tests of successive synthesis. Factor analyses of the test intercorrelations for each group revealed more factorial invariance across the IQ groups than had been suggested by a previous exploratory study. It was concluded that strong individual differences exist in simultaneous and successive syntheses over the major portion of the standardized intelligence range, and no high degree of specialization of information processing was characteristic of an intelligence group. 相似文献
