Rats emit distinct types of ultrasonic vocalizations (USVs), which serve as situation-dependent affective signals. In appetitive situations, such as rough-and-tumble-play, high-frequency 50-kHz USVs occur, whereas low-frequency 22-kHz USVs can be observed in aversive situations, such as social defeat. USVs serve distinct communicative functions and induce call-specific behavioral responses in the receiver. While aversive 22-kHz USVs serve as alarm calls and induce behavioral inhibition, appetitive 50-kHz USVs have a pro-social communicative function and elicit social approach behavior, supporting the notion that they serve as social contact calls to (re)establish or maintain contact among conspecifics. The aim of the present study was to use the rat's ability to communicate in the ultrasonic range via high-frequency 50-kHz USVs in order to develop a test for social acoustic memory in rats with relevance for human verbal memory. Verbal learning and memory is among the seven cognitive domains identified as commonly deficient in human schizophrenia patients, but particularly difficult to model. We therefore tested whether the induction of social approach behavior by playback of appetitive 50-kHz USVs is dependent on (1) acoustic stimulus configuration and (2) social long-term memory, and whether (3) social long-term memory effects can be blocked by the administration of scopolamine, a muscarinic acetylcholine antagonist producing amnesia. Results show that social approach behavior in response to playback of natural 50-kHz USVs depends on acoustic stimulus configuration and occurs only when sound energy is concentrated to a critical frequency band in the ultrasonic range. Social approach behavior was detected during the first exposure to playback of 50-kHz USVs, whereas no such response was observed during the second exposure 1week later, indicating a stable memory trace. In contrast, when memory formation was blocked by i.p. administration of scopolamine (0.5mg/kg or 1.5mg/kg) immediately after the first exposure, rats displayed social approach behavior during the second exposure as well. Induction of social approach behavior in response to repeated playback of natural 50-kHz USVs may therefore provide a new and rather unique approach for testing social acoustic memory in rats with relevance to human verbal memory. 相似文献

Background. Handwriting legibility systematically biases evaluations in that highly legible handwriting results in more positive evaluations than less legible handwriting. Because performance assessments in educational contexts are not only based on computerized or multiple choice tests but often include the evaluation of handwritten work samples, understanding the causes of this bias is critical. Aims. This research was designed to replicate and extend the legibility bias in two tightly controlled experiments and to explore whether gender‐based inferences contribute to its occurrence. Sample(s). A total of 132 students from a German university participated in one pre‐test and two independent experiments. Method. Participants were asked to read and evaluate several handwritten essays varying in content quality. Each essay was presented to some participants in highly legible handwriting and to other participants in less legible handwriting. In addition, the assignment of legibility to participant group was reversed from essay to essay, resulting in a mixed‐factor design. Results. The legibility bias was replicated in both experiments. Results suggest that gender‐based inferences do not account for its occurrence. Rather it appears that fluency from legibility exerts a biasing impact on evaluations of content and author abilities. Conclusions. The legibility bias was shown to be genuine and strong. By refuting a series of alternative explanations, this research contributes to a better understanding of what underlies the legibility bias. The present research may inform those who grade on what to focus and thus help to better allocate cognitive resources when trying to reduce this important source of error. 相似文献

What role does social identity play in the transition from employed work to entrepreneurship? It was expected that social identity affects the cognitive processes that, according to the theory of planned behavior (TPB), underlie the formation of entrepreneurial intentions. Focusing on academic scientists' intentions to commercialize research knowledge, we investigated social identity (scientists' group identification with their workplace peers in academia) as a moderator in the TPB model. Our hypotheses were tested in a sample of 488 German scientists. The data revealed that entrepreneurial intentions were predicted by attitude, social norms, and perceived control and that group identification was negatively associated with perceived control. Multi-group structural equation modeling further showed that group identification moderated the TPB-intention link. Scientists with low group identification based their entrepreneurial intentions not so much on social norms and attitudes but on their self-initiative and control beliefs. Among scientists with high group identification, in turn, entrepreneurial intentions were mainly a function of social norms. These results, in sum, illustrate the long-neglected importance of identification with, and social cohesion within, peer groups at the workplace for the transition to entrepreneurship. 相似文献

Why was death considered polluting within classical Greek society when Olympian sacrifice was ubiquitous? Outside the polis the Greeks’ view of the uncultivated or improperly cultivated geography and of their own ‘city-less’ past was just the other way around. Here death represented no pollution whatsoever, while Olympian sacrifice was either absent or not properly performed. Death and life had yet to be separated, as had happened in the proper human realm of the Greek polis. Any reintroduction of either natural death or sacrifice into the ‘city of life’ would consequently negate its very structures. Sacrifice differed exactly through the aspect of control. Acts of sacrifice were therefore used to control the onset of natural death. But why would the Greeks sacrifice also in every other possible context? As the essential human characteristic, mortality pertained to all human creations, including the polis. Left to itself, the polis would wither and die. Through Olympian sacrifice, humans dissolved the structures of the city without ever losing control, thereby introducing the unlimited potential as still found in the primordial state of the uncultivated geography. The structures of the polis were recreated through the proper division of the sacrificial victim. 相似文献

Objective: Compensatory health beliefs (CHBs), defined as beliefs that healthy behaviours can compensate for unhealthy behaviours, may be one possible factor hindering people in adopting a healthier lifestyle. This study examined the contribution of CHBs to the prediction of adolescents’ physical activity within the theoretical framework of the Health Action Process Approach (HAPA).Design: The study followed a prospective survey design with assessments at baseline (T1) and two weeks later (T2).Method: Questionnaire data on physical activity, HAPA variables and CHBs were obtained twice from 430 adolescents of four different Swiss schools. Multilevel modelling was applied.Results: CHBs added significantly to the prediction of intentions and change in intentions, in that higher CHBs were associated with lower intentions to be physically active at T2 and a reduction in intentions from T1 to T2. No effect of CHBs emerged for the prediction of self-reported levels of physical activity at T2 and change in physical activity from T1 to T2.Conclusion: Findings emphasise the relevance of examining CHBs in the context of an established health behaviour change model and suggest that CHBs are of particular importance in the process of intention formation. 相似文献

At present, it is not well understood which individual characteristics determine whether individuals will benefit or suffer from feedback about suboptimal performance. Three separate studies tested the idea that individuals' reactions to (neutral versus negative; positive versus negative) feedback as either improving or deteriorating performance in intelligence tests depended on their explicit and implicit self‐concept of intelligence (eSCI and iSCI). In all studies (Study 1, N = 177; Study 2, N = 165; Study 3, N = 132), persons with low eSCI/high iSCI showed a boost in performance after negative feedback, whereas persons with any other combination showed a decline in performance. The studies also provide an explanation for these effects in terms of mediating mechanisms. Whereas the performance boost of individuals with low eSCI/high iSCI can be best explained by achievement‐related reactance (Studies 2 and 3) and decrease in ruminative thinking (Study 3), the performance declines in the other configurations were mediated by decreased achievement motivation, increased frustration and increased outrage (Study 3). All these mediating mechanisms proved independent and incremental in a bootstrapping‐based moderated meditation analysis. The results are discussed in light of the construct validity of our Implicit Association Test (IAT) and IATs in general. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Abstract According to Erich Fromm and a relational psychoanalytic approach, changing economic and social requirements always impact human beings and their psychic structure. Because globalization leads particularly to a blurring of boundaries and limitations, the formation of a new character orientation that is driven to construct reality anew without limitations can be observed as a reaction in progress. The pathogenic effects of globalization can be studied through the analysis of this new character formation and the uncovering of repressed, unconscious feelings that characterize the new personality type, especially in regard to their sense of identity, their way of relating to others, and their de facto loss of ego strength – in contrast to the enacted “ego unlimited.” Finally, some aspects of transference and countertransference, as well as some particular defense reactions with which we psychoanalysts are confronted in the treatment of patients suffering from the pathogenic effects of globalization, will be discussed. 相似文献

We review the recent research literature on pro-criminal attitudes (PCAs) as a causal factor of recidivism with a focus on studies on the effectiveness of offender treatment programs targeting PCAs to prevent recidivism. The main conclusions that can be derived from the literature are: (1) the evidence supports the hypothesis that PCAs are related to reoffending; (2) most investigated offender treatment programs tend to reduce PCAs, although the general lack of adequate control group designs does not rule out alternative explanations for this reduction; and (3) there is no conclusive empirical evidence that intervention programs designed to reduce PCAs are effective in reducing recidivism. Empirical research in this area lacks the theoretical and methodological rigor to test causal models of the influence of treatment on reducing PCAs, and effects of PCAs on recidivism. Limitations of the empirical evidence are related to inadequate research designs and/or suboptimal data analysis strategies. Recommendations concerning optimized research designs and data analysis strategies that are likely to provide more conclusive evidence on the relation of PCAs, PCA treatment, and recidivism are given. 相似文献
