Emotionally arousing events are typically better remembered and more resistant to forgetting than neutral events. Findings from word list paradigms suggest that this may not hold for individuals with Autism Spectrum Disorder (ASD), who also tend to be less accurate as eyewitnesses under some circumstances. To test whether attenuated effects of arousal on memory may be responsible for poorer eyewitness testimonies in ASD, we asked adults with and without the disorder to view either arousing or neutral versions of a narrated slide sequence (Experiment 1) or video clip (Experiment 2) before assessing their memory for the material. Both groups exhibited increases in psychophysiological arousal during the arousing compared with the neutral version of the narratives, and both groups also demonstrated a memory advantage for the arousing events. Contrary to predictions, these observations indicate that stimulus induced arousal modulates memory for naturalistic events relatively typically in ASD.

The religious economies model has been influential in the sociology of religion. Yet, propositions drawn from the model have been difficult to test in the comparative and historical study of religion, generally for lack of appropriate data. We develop a general theory of religious disestablishment and apply it to the Reformation in 16th‐century Europe to explain variation in the abolition of the Catholic monopoly. We suggest three principal factors—changes in demand, entry control mechanisms, and political incentives—that explain why incumbent religious firms may lose their monopoly. We then analyze the resulting hypotheses in a systematic analysis of cities in the Holy Roman Empire. Our analysis yields mixed support for demand‐side factors and entry control mechanisms, and firm support for political incentives in the institution of reform. 相似文献

Domestic dogs (Canis familiaris) and the radial arm maze: Spatial memory and serial position effects
M Craig J Rand R Mesch M Shyan-Norwalt J Morton E Flickinger 《Journal of comparative psychology (Washington, D.C. : 1983)》2012,126(3):233-242
The present study investigated spatial memory in domestic dogs (Canis familiaris) through the use of a radial arm maze. The study consisted of a total of three separate experiments. In the first two experiments, the ability of the dogs to successfully remember previously unentered arms was evaluated. The third experiment was similar to the first two, but also examined the nature of the serial position effect. Performance in all three experiments was better than expected solely by random choices. Dogs showed a much better memory for spatial locations presented earlier in a spatial list compared with those presented in the middle. Based on the present results, we suggest that the radial arm maze assesses canine spatial memory and that dogs show a primacy effect.

Two experiments (N=136) studied how 4- to 6-month-olds perceive a simple schematic event, seen as goal-directed action and reaction from 3 years of age. In our causal reaction event, a red square moved toward a blue square, stopping prior to contact. Blue began to move away before red stopped, so that both briefly moved simultaneously at a distance. Primarily, our study sought to determine from what age infants see the causal structure of this reaction event. In addition, we looked at whether this causal percept depends on an animate style of motion and whether it correlates with tasks assessing goal perception and goal-directed action. Infants saw either causal reactions or noncausal delayed control events in which blue started some time after red stopped. These events involved squares that moved either rigidly or nonrigidly in an apparently animate manner. After habituation to one of the four events, infants were tested on reversal of the habituation event. Spatiotemporal features reversed for all events, but causal roles changed only in reversed reactions. The 6-month-olds dishabituated significantly more to reversal of causal reaction events than to noncausal delay events, whereas younger infants reacted similarly to reversal of both. Thus, perceptual causality for reaction events emerges by 6 months of age, a younger age than previously reported but, crucially, the same age at which perceptual causality for launch events has emerged in prior research. On our second question, animate/inanimate motion had no effect at any age, nor did significant correlations emerge with our additional tasks assessing goal perception or goal-directed object retrieval. Available evidence, here and elsewhere, is as compatible with a view that infants initially see A affecting B, without differentiation into physical or psychological causality, as with the standard assumption of distinct physical/psychological causal perception. 相似文献

The present research examines whether the experience and the expectation of residential mobility related to the type of helpers whom people wanted to befriend and work with. We predicted and found that people who moved more frequently before college (Studies 1 and 2) preferred those who were likely to extend a helpful hand to those outside their immediate social circles. By contrast, people who had not moved preferred those who prioritized helping in-group members over strangers. Study 3 tested the hypothesis by priming the expectation of residential mobility versus stability and replicated the findings with residential mobility but did not find difference in the stability condition. These results suggest that residential mobility does not merely change people's living environments but also affects interpersonal preferences and with whom people would like to associate. 相似文献

Intergroup research has focused primarily, if not solely, on how an intergroup comparative context primes social categorization. The current research examines how individual differences, in terms of distinct forms of social self (the relational versus collective self), differentially drive social categorization and zero-sum resource allocation across groups nested within a superordinate group. Results show that the relational self exhibited more ingroup-biased allocations than the collective self; superordinate categorization mediated this relationship. Moreover, the relational self showed more ingroup-biased allocations under the condition of intergroup competition than cooperation; whereas the collective self showed equally unbiased allocations under the conditions of intergroup competition and cooperation. Our research suggests that competition worsens nested group relations for the relational self, but not for the collective self. 相似文献

This study evaluated hypothesized positive linkages between organizational citizenship behavior and the emotional intelligence dimensions of perception, using emotion, understanding emotion, and management of emotion, involving two samples. Sample 1 comprised 334 employed college students, 52% male, with a mean age of 23.4 yr., who worked an average of 29.6 hr. per week. Sample 2 comprised 72 professors, 81% female, with a mean age of 47 yr. Measures were the Emotional Intelligence Scale and the Organizational Citizenship Behavior Scale. Results of hierarchical multiple regressions indicated a positive link between organizational citizenship behavior and emotional intelligence. There were differences between the samples. In Sample 1, each of the emotional intelligence dimensions were positively linked to citizenship behavior: using and managing emotion were the greatest contributors. In Sample 2, managing emotion was the only contributor. Emotional intelligence had the strongest relationship with citizenship behavior directed at individuals. 相似文献

Recent stereotype threat research has demonstrated that negative stereotypes about women's math ability can impair their mathematical learning. This experiment extends this research by examining whether presenting “gender fair” information can reduce learning decrements (on a focal and transfer task) and if the timing of this information matters. Women (N = 140) and men (N = 60) were randomly assigned to one of four conditions: control, stereotype threat only, stereotype threat removed before learning, and stereotype threat removed after learning. Compared with women in the control condition and women who had stereotype threat removed before learning, learning and transfer were poorer for women in the stereotype threat only condition and women who had stereotype threat removed after learning but before learning assessment. Men's learning and transfer were unaffected by condition. These findings suggest that a manipulation that can reduce performance deficits can also reduce learning decrements if it is presented before learning occurs.

As research continues to document differences in the prevalence of mental health problems such as depression across racial/ethnic
groups, the issue of measurement equivalence becomes increasingly important to address. The Mood and Feelings Questionnaire
(MFQ) is a widely used screening tool for child and adolescent depression. This study applied a differential item functioning
(DIF) framework to data from a sample of 6th and 8th grade students in the Seattle Public School District (N = 3,593) to investigate the measurement equivalence of the MFQ. Several items in the MFQ were found to have DIF, but this
DIF was associated with negligible individual- or group-level impact. These results suggest that differences in MFQ scores
across groups are unlikely to be caused by measurement non-equivalence. 相似文献
