The generalizability of the Fishbein model for behavior prediction was extended to a new field behavior, alcohol drinking by adolescents. The model's two components (i.e., attitudes and normative beliefs) varied in their predictive importance depending on the behavior's situational context. Following this field demonstration, two issues related to properties affecting the model's predictive effectiveness were investigated. First, it was found that the predictability of alcohol-drinking intentions (BI) declined when attitudes (Aact) and normative beliefs (NB) did not correspond with BI in terms of alcohol type (beer, liquor, or wine) and drinking situation (home, party, or pub). A second experiment tested the hypothesis that exogenous variables (those other than Aact and NB) would have a direct influence on BI. A comprehensive test was provided within the context of Jessor's multivariate predictive system for adolescent alcohol use. Present data indicate only a marginal increase in explained variance occurred when applying this system, thereby generally indicating the sufficiency of the Fishbein model's two components.  相似文献

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

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

Two groups of six 3-month-old infants participated in a study which contained four consecutive 2-min periods. During Periods 2 and 4 both groups received adult social stimulation on the same prearranged schedule. The treatments during Periods 1 and 3 differed between the two groups; no adult was present for the A-S group, while the B-S group received the typical operant baseline (unresponsive adult treatment) for these two periods. Social stimulation caused a significant increase in vocal rate from the preceding control period for both groups. Infants in the A-S group vocalized at the same rate during the two periods in which the adult was absent and at similar rates during the two stimulation periods. For infants in the B-S group, baseline procedures suppressed vocal rates and did not provide a neutral or operant level of responding with which the effects of social conditioning could be compared.  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

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

The present study investigated the effects of situational constraint and type of causal explanation on the degree to which described behavior would be perceived as evidencing “mental illness” and the degree to which it would lead to social rejection.Results showed that both of these variables influenced the degree of attributed “mental illness”, the degree of attributed psychological disturbance, and the degree of social rejection. Behavior inappropriate to a situation was rated higher on all three of these variables. Behavior attributed to external pressures received lower ratings on these variables than that attributed to internal causes, to organic causes, or for which no apparent explanation was available.  相似文献

In a theory chain extending Byrne's theory of social attraction, links are described between breadth of social interaction and complexity of the self-concept as well as between complexity of the self-concept and social attraction. In the first series of studies, it was shown that communication-handicapped adolescents and physically handicapped children, as well as terminally ill patients, indicate lower self-complexity. In a second series of studies, it was found that persons with more complex self-concepts identify more closely with others, perceive themselves as more similar to objectively dissimilar others, and are more popular sociometrically.  相似文献

Evoked potentials of 16 human infants (mean age = 5.0 weeks, SD = 1.8 weeks) were recorded from the left and right, occipital and temporal areas. Spectral analysis showed a high amplitude, localized, coherent center of activity within the left temporal area for click stimuli, and a high amplitude, localized center of activity in the right occipital area for flash stimuli. It was proposed that the structured auditory information of the click and the unstructured visual information of the flash represented different degrees of familiarity to the subjects. With this hypothesis, left hemisphere involvement in stimulus processing would increase as the stimulus became more referrable to previous long- or short-term experience. Conversely, right hemisphere involvement would increase with unfamiliar stimuli which could not be readily associated with earlier data.  相似文献
