The cognitive attribution theory of achievement motivation was examined in a series of three studies. The persistence of performance under failure feedback was investigated, with improvement over trials on a digit-symbol substitution task constituting the measure of persistence. Although evidence was obtained relating overt causal attributions of failure to persistence, partial correlation statistics indicated that this relationship was independent of achievement motivation. Partial correlation statistics also revealed that the relationship between achievement motivation and persistence was independent of attributional variables. In addition, greater persistence was exhibited by high- than by low-achievement subjects in the absence of attribution differences between these groups. Additional evidence was collected suggesting that the act of overt attribution was an ego-involving operation that led to these achievement differences in improvement. In general, achievement classification and overt causal attributions had separate effects on persistence, precluding the interpretation of achievement-related behavior in terms of attribution theory. Overt causal attributions were found to be, in part, a function of the ego-involving character of the task instructions, as was improvement.Portions of this research were conducted while L. A.

Two experiments were conducted to examine laterality differences and practice effects under various central backward masking conditions. Critical stimulus onset asynchrony (SOA) was determined for subjects on 3 consecutive days using single letters as target stimuli (TS) and a pattern masking stimulus (MS). There was a right visual field (RVF) advantage on Day 1 but no difference between the visual fields on following days. The decline in the RVF advantage appeared to be dependent upon prior experience with laterally located letters, to be independent of initial experience with a particular set of letters, and to be more pronounced for females than for males. In addition, large improvements in performance were found, particularly between the first and second testing sessions. These practice effects were discussed in terms of the possible development of strategies for enhancing TS features or attenuating MS features. 相似文献

Ten male and 10 female subjects, half of whom were classified as “heavy” and half as “light” drinkers, ingested a 4-1 combination of tonic water and 80-proof vodka in an amount calculated to produce a state of moderate intoxication (average estimated peak blood alcohol level=.075). This resulted in an increased sensitivity (latency, magnitude, and duration) to the calorically induced “oculogyral illusion” (OGI) relative to a placebo (tonic water) condition. “Heavy” and “light” drinkers did not differ significantly on any of the measures. It was speculated that the alcoholic enhancement of the OGI was due either to a decreased ability to suppress vestibular nystagmus when attempting to fixate a visual stimulus or to the expenditure of extra-normal effort in order to maintain fixation. 相似文献

University men participating in an ostensible study of “impression formation” first received either an insulting or neutral evaluation of themselves from their supposed partner and then watched either a prize fight or an exciting but nonaggressive scene. After this, they either had an opportunity to evaluate their partner right away or they had to wait an hour before evaluating him. On scoring the subjects' written statements about the partner (to be seen by him and the experimenter), it was found that (1) for those given the immediate opportunity to be aggressive, the violent movie increased the strength of the angered subjects' initial attack on their partner over that displayed by the similarly insulted men shown the nonaggressive film; (2) if the angry subjects had to wait an hour before evaluating their partner, there was no difference between the aggressive and nonaggressive movie groups; (3) the aggression-heightening effect of the violent scene did carry over the intervening hour, however, if the insulted men had been given the earlier opportunity to evaluate their partner. It is suggested that the performance of an aggressive response soon after seeing an aggressive film increases the persistence of the aggressive reactions over time. 相似文献

On the basis of recent findings showing that physical attractiveness serves as an important evaluative cue in person perception, the present paper reviews evidence which indicates that physical attractiveness differentially affects the judgments of males and females. Recent research seems to indicate that the physical-attractiveness stereotype — which holds that attractive individuals are more positively evaluated across a wide range of dimensions than unattractive individuals — is more potent when applied to women than to men. The origins of this differential stereotyping are discussed in terms of the historically defined roles of men and women in our society. In addition, the paper discusses the implications of the physical-attractiveness stereotype for the general problem of sex-role stereotyping. 相似文献

The challenge of providing high-quality public defense services continues to be a concern at federal, state, and local levels. Some scholars have alluded to a potential solution in client-centered representation, but research in this area is sparse at best. Such a lack of understanding leaves in its place speculation, particularly as to the potential importance of client perceptions in shaping broader system legitimacy. To fill this gap and create an empirical platform for future research, an exploratory pilot study was launched with the Hamilton County, Ohio Public Defender's Office, which used mixed methodologies to assess client attitudes toward public defenders as a potential resource for aiding the improvement of indigent representation. Findings from this pilot study suggest that there are five factors a public defense attorney should address that may prove to be very important in obtaining client satisfaction and cooperation: engaging the client for input, listening to the client, examining the prosecutor's evidence, focusing on the client's case during meetings, and informing the client of potential consequences. Implications for practice and future research are discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
