Three experiments address how people react to a sexual abuse victim compared to a nonvictim when a justification for negative evaluation is available or not available. A harm-doing victim was rated lower on expected job performance and higher on desired social distance than a harm-doing nonvictim. When subsequent harm-doing was absent, judgments of a victim and nonvictim did not differ on expected job performance or social distance. Experiment 2 replicated the results of Experiment 1 and revealed that the order in which victimization history and harm-doing information were presented had no effect. Experiment 3 showed that participants desired greater social distance from a harm-doing victim compared to a non-harm-doing victim to the extent they thought the target should have derived benefits from the childhood victimization. Implications for judgments of harm-doers—depending on whether their victimization history is known or not—are considered. 相似文献

In this article, we review past studies comparing randomized experiments to regression discontinuity designs, mostly finding similar results, but with significant exceptions. The latter might be due to potential confounds of study characteristics with assignment method or with failure to estimate the same parameter over methods. In this study, we correct the problems by randomly assigning 588 participants to be in a randomized experiment or a regression discontinuity design in which they are otherwise treated identically, comparing results estimating both the same and different parameters. Analysis includes parametric, semiparametric, and nonparametric methods of modeling nonlinearities. Results suggest that estimates from regression discontinuity designs approximate the results of randomized experiments reasonably well but also raise the issue of what constitutes agreement between the 2 estimates. 相似文献

The developmental course of multidimensional speech processing was examined in 80 children between 3 and 6 years of age and in 60 adults between 20 and 86 years of age. Processing interactions were assessed with a speeded classification task (Garner, 1974a), which required the subjects to attend selectively to the voice dimension while ignoring the linguistic dimension, and vice versa. The children and adults exhibited both similarities and differences in the patterns of processing dependencies. For all ages, performance for each dimension was slower in the presence of variation in the irrelevant dimension; irrelevant variation in the voice dimension disrupted performance more than irrelevant variation in the linguistic dimension. Trends in the degree of interference, on the other hand, showed significant differences between dimensions as a function of age. Whereas the degree of interference for the voice-dimension-relevant did not show significant age-related change, the degree of interference for the word-dimension-relevant declined significantly with age in a linear as well as a quadratic manner. A major age-related change in the relation between dimensions was that word processing, relative to voice-gender processing, required significantly more time in the children than in the adults. Overall, the developmental course characterizing multidimensional speech processing evidenced more-pronounced change when the linguistic dimension, rather than the voice dimension, was relevant. 相似文献

We examined the interactive effects of ethnic identification (EI) and race-based rejection sensitivity (RS-race) on institutional outcomes among African American college students. We distinguished between effects on institutional identification on the one hand and academic goal pursuit (e.g., staying in school, grade point average [GPA]) on the other. Supporting the utility of this distinction, we found that EI and RS-race interacted to predict these outcomes differently. Higher EI in combination with higher RS-race predicted reduced identification with the institution (Studies 1, 2, and 3a). This combination, however, did not lead to decreases in GPA over time. Moreover, EI was positively related to intentions to stay in school as well as to GPA increases among those lower in RS-race (Studies 1 and 3b). Implications for understanding identity negotiation vis-à-vis performance in institutional settings are discussed. 相似文献

Status-based rejection sensitivity among asian americans: implications for psychological distress 总被引:1,自引:0,他引:1
We examined whether anxious expectations of discrimination among Asian Americans can help explain this group's elevated levels of internalizing symptomatology, such as lower self-esteem (Twenge & Crocker, 2002) and higher depressive symptoms (Okazaki, 1997, 2002) relative to European Americans. Study 1 reports on the development and validation of a scale measuring status-based rejection sensitivity among Asian Americans (RS-A). In Study 2, scores on the RS-A were related to spontaneous discrimination attributions specifically in situations where discrimination is both applicable and possible for Asian Americans. Study 3 revealed that shame mediated the relationship between RS-A and internalizing symptomatology. Implications for well-being and intergroup interactions are discussed. 相似文献

The idea of a probabilistic logic of inductive inference based on some form of the principle of indifference has always retained
a powerful appeal. However, up to now all modifications of the principle failed. In this paper, a new formulation of such
a principle is provided that avoids generating paradoxes and inconsistencies. Because of these results, the thesis that probabilities
cannot be logical quantities, determined in an objective way through some form of the principle of indifference, is no longer
supportable. Later, the paper investigates some implications of the new principle of indifference. To conclude, a re-examination
of the foundations of the so-called objective Bayesian inference is called for. 相似文献

This study falls within the theoretical framework of the construct of the Efficient Personality. In this work, we present the study of validity and reliability of an original questionnaire made up of 60 items, applied to students from formative cycles of higher Professional Training. The questionnaire was reduced to 24 items, surpassing its initial .84 Cronbach alpha coefficient. Six first-order factors were obtained: Social Self-concept, Academic Self-concept, Solving Ability, Self-esteem, and Problem Coping. One second-order factor was obtained: Efficient Personality. The six-component factorial solution is similar both to the Spanish version for secondary school and to the Chilean versions for secondary and university populations, dividing the initial dimension of Self-concept into Self-concept and Self-esteem. 相似文献

The current article attempts to extend previous research by testing the effects of customer satisfaction and 2 types of switching barriers—negative and positive—on key manifestations of attitudinal loyalty (repurchase intentions, positive recommendations, and price tolerance). The work also studies whether the effect of customer satisfaction is linear or nonlinear. Finally, the paper analyzes whether switching barriers moderate the relative strength of the customer satisfaction/attitudinal loyalty relation. To this end, a total of 554 private mobile‐phone customers were surveyed. The distinction between negative and positive switching barriers is important to draw theoretical and managerial implications. 相似文献

The limits of a drug therapy in severe forms of Parkinson disease have led to refining neurosurgery on the basal ganglia. Deep brain stimulation of the subthalamic nucleus has been recognized as one of the most promising techniques to decrease "off" motor symptoms and motor fluctuations, allowing a reduction of drug therapy and limiting side effects of the drugs. There is still open debate on the possible consequences of chronic subthalamic stimulation in other ways, apart from motor symptoms, of general cognitive performance. We examined and followed two patients with Parkinson disease for 9 mo. after surgery for deep stimulation, studying their cognitive performances. There is a general amelioration of cognitive performances, in particular as far as linguistic capabilities is concerned. We discuss the possible significance of these results, reminding strenuously that only two patients were involved, so the potential for generalization is seriously limited. 相似文献

Pretraining systemic administration of p-chloroamphetamine (PCA) consistently produces retention deficits of inhibitory avoidance. This drug causes a widespread acute release of serotonin from cerebral neuronal terminals, but it is not known where in the brain PCA exerts its disruptive cognitive effects. The present experiment was aimed at determining whether the striatum is a site of action of this drug. PCA (5 microg) was infused, bilaterally, into the striatum of rats at 30, 15, or 5 min before training of inhibitory avoidance, and retention of the task was measured 24 h later. An inversely related time-dependent deficit was found. Together with the results from appropriate control groups, this result strongly suggest that systemic PCA produces its reported cognitive effects, at least in part, through its pharmacological action within the striatum. 相似文献
