The joint effects of stimulus modality, stimulus intensity, and foreperiod on simple RT were investigated. In experiment 1 an interaction was found between stimulus intensity, both visual and auditory, and a variable FP such that the intensity-effect on RT was largest at the shortest FP. Experiment 2 provided a successful replication with smaller and weaker visual stimuli. No interaction was observed with a constant FP, although the visual stimuli were identical and the auditory ones psychophysically equivalent to the visual stimuli of experiment 1.It is proposed that an additive or interactive relationship between stimulus intensity and FP can be inferred only when the mental processes called for by the various uses of FP are simultaneously considered. Another precondition is an adequate sampling of the intensity-continuum with special reference to the retinal size of visual stimuli. 相似文献

This study was designed to investigate the predictive efficiency of the primary and secondary summary codes of Holland's Self-Directed Search for Educational and Vocational Planning (SDS) in terms of expressed career choice 4 years later. In 1974, 126 voiationally undecided high school seniors were given the SDS, followed by a revision of Trow's Vocational Choice Inventory (VCI) in which they were asked to express a career choice or a state of indecision. In 1978, this same group was mailed a posttest VCI; the responses of 84 subjects were then analyzed. The subjects' expressed career choices on both the 1974 and 1978 VCI were compared to the primary and secondary summary codes on the SDS which they had taken in 1974. Inspection of the responses indicated that 21.4% of the subjects had made career choices predicted by their primary summary codes and 51.2% had made vocational choices found among their secondary summary codes. Only 27.4% chose a career area not predicted by their 1974 SDS results. The results of this study appear to lend support to the validity of using the SDS summary codes to predict eventual career decisions. 相似文献

An experiment was conducted to investigate an interpersonal process that contributes to the perpetuation of stereotyped beliefs about women and men. Male-female pairs of unacquainted individuals interacted to negotiate a division of labor on a series of work-like tasks (that differed in their sex-role connotations) in a situation that permitted control over the information that male perceivers received about the apparent sex of female targets. The perceivers' beliefs about the sex of their targets initiated a chain of events that resulted in targets providing behavioral confirmation for perceivers' beliefs about their sex. Targets believed by perceivers to be male chose tasks relatively masculine in nature, and targets believed by perceivers to be female chose tasks relatively feminine in nature. Although this behavioral confirmation effect was initially elicited as reactions to overtures made by perceivers, it persevered so that eventually targets came to initiate behaviors “appropriate” to the sex with which they had been labeled by perceivers. The specific roles of perceivers and targets in the behavioral confirmation process are examined. Implications of these findings for the perpetuation of stereotyped beliefs about the sexes are discussed. 相似文献

A total of 224 subjects in grades 2, 4, 6, 8, high school, and college solved problems requiring comprehension of the logical connectives and, or, if-then, only if, and if and only if, as well as the terms is and is not. Half the subjects were required merely to encode the connectives; the other half were required to combine as well as encode them. Problems were presented in two replications (over two sessions) via two different content vehicles. Quantitative analyses revealed significant effects of task, age, session, and connective, with comprehension of different connectives developing at different rates. In general, comprehension of the conjunctive connective was easiest; comprehension of the conditional and biconditional connectives was most difficult. Qualitative analyses indicated just how the logical connectives were interpreted at each grade level, and also investigated individual differences within each grade level. 相似文献

Temporal aspects of early visual information processing were studied developmentally in good and in poor reading male subjects ranging in age from 7 to 13 years. Forced-choice temporal integration and backward masking tasks, respectively, were utilized to assess duration of visual persistence and of relative rate of visual information processing. The results did not reveal differences in either visual persistence or processing rate in relation to reading ability at any age level studied. However, processing rate was found to increase markedly with chronological age in both the good and the poor readers while visual persistence did not vary significantly. The findings were discussed in relation to earlier work and in relation to current theoretical formulations of visual information processing. 相似文献

The study investigated how the sincerity of models affects their influence, using a delay-of-reward paradigm. Subjects were 40 fifth and sixth graders (ages 9 and 10 years, respectively), selected for delayed gratification patterns. In the experimental manipulation, sincerity or insincerity was explicitly attributed to the model or, in a neutral-model condition, no information about the model's sincerity was given. Subjects then observed the symbolically presented model's immediatereward choices, opposed to their own preferences. Immediately after treatment, children in all model conditions and in a fourth, no-model control group responded to a second delay-preference test. It was found that the influence of models varied substantially as a function of experimentally attributed sincerity. Insincere models had considerably less effect than sincere and neutral models, who provoked substantial and equivalent changes. Insincere models did not evoke significantly different change than occurred in the control group. A postexperimental inquiry showed the experimental manipulation had affected perceptions of the model's sincerity and liking for the model, with the insincere model rated considerably lower than the sincere and neutral models. The relevance of cognitive appraisal in observational learning was discussed. 相似文献

Fazio, Zanna, and Cooper (Dissonance and self-perception: An integrative view on each theory's proper domain of application. Journal of Experimental Social Psychology, 1977, 13, 464–479) specified mutually exclusive domains of application for dissonance and self-perception theory and used a misattribution-of-arousal procedure to distinguish between dissonance reduction and self-perception processes. Because their proposed limitations of the domains of the two theories and their use of the misattribution procedure are not directly derivable from earlier statements of either theory, it may be best to regard their analysis as a new theory, rather than as a conciliation of the parent theories. New analyses based on the Fazio et al. results indicate that their data provide an insufficient basis for preferring their theory to earlier versions of dissonance and self-perception theories.

Effects of household sex composition on the salience of one's gender in the spontaneous self-concept
William J McGuire Claire V McGuire Ward Winton 《Journal of experimental social psychology》1979,15(1):77-90
It was hypothesized that being a boy or a girl becomes more salient in a child's self-concept to the extent the other sex numerically predominates in the child's household. This prediction was based upon an information-processing, distinctiveness postulate that a person contemplating a complex stimulus (such as the self) selectively notices and encodes its more distinctive, information-rich aspects. The spontaneous self-concept elicited by nondirective “Tell us about yourself” interviews of 560 school children were scored for spontaneous mention of one's gender. As predicted, boys spontaneously mentioned their maleness more often when they came from households where females were in the majority; girls mentioned their femaleness more often when from households with male majorities; boys mentioned their maleness more often when from father-absent than from father-present homes. Incidental findings are that gender is more salient in the negation self-concept (“Tell us what you are not”) than in the affirmation self-concept (“Tell us about yourself”) especially for girls and that gender becomes increasingly salient as the child grows older. 相似文献
