Several studies have reported similarities between perceptual processes underlying face and body perception, particularly emphasizing the importance of configural processes. Differences between the perception of faces and the perception of bodies were observed by means of a manipulation targeting a specific subtype of configural processing: the composite illusion. The composite face illusion describes the fact that two identical top halves of a face are perceived as being different if they are presented with different bottom parts. This effect disappears, if both halves are laterally shifted. Crucially, the effect of misalignment is not observed for bodies. This study aimed to further explore differences in the time course of face and body perception by using the composite effect. The present results replicated behavioural effects illustrating that misalignment affects the perception of faces but not bodies. Thus, face but not body perception relies on holistic processing. However, differences in the time course of the processing of both stimulus categories emerged at the N170 and P200. The pattern of the behavioural data seemed to be related to the P200. Thus, the present data indicate that holistic processes associated with the effect of misalignment might occur 200 ms after stimulus onset.  相似文献

Drawing upon uncertainty-identity theory, we argue that self-uncertainty creates a motivated mindset in which people desire to have their social identity validated thorough inclusion, and that this transforms the meaning of group warmth and competence to cue inclusion. US College students (N = 289) participated in an on-line experiment in which self-uncertainty and the perceived warmth and competence of their college were primed, and group identification was measured as the dependent variable. As predicted, the three-way interaction significantly affected group identification. Specifically, uncertainty weakened identification with cold-but-competent groups. We also found that uncertainty strengthened identification with cold-and-incompetent groups. This research highlights the preference for certain group attributes under uncertainty.  相似文献

This paper examined how individual group status and happiness influence forgiveness. In Study 1, happiness was treated as a trait difference: highly happy people, compared with very unhappy people, were found to be more willing to forgive murderers. More important, an interaction effect between happiness and group status on forgiveness was found, that is, highly happy people tended to be more forgiving when either ingroup or outgroup members were killed; unhappy people, however, tended to be less forgiving about murder when ingroup rather than outgroup members were killed. In Study 2, happiness was treated as an emotional state difference: happiness, rather than sadness, was found to bring greater forgiveness. Moreover, consistent with the interaction effect displayed in Study 1, happy participants tended to forgive more when ingroup or outgroup members were hurt; sad participants tended to forgive less when ingroup members rather than outgroup members were hurt. Implications for connections between happiness, group membership, and forgiveness are discussed.  相似文献

PurposeTo examine potential deficits in muscle strength or functional capacity when comparing (1) an ACL reconstructed group to matched healthy controls, (2) the ACL reconstructed leg to the non-injured leg and (3) the non-injured leg to matched healthy controls, at the time-point of recommended sport return 9–12 months post-surgery.MethodsSixteen patients (male-female ratio: 9:7) 9–12 months post ACL reconstruction and sixteen age and sex matched healthy controls were included. Outcome measures included maximal knee extensor (KE) and knee flexor (KF) dynamometry, including measurement of rate of force development, functional capacity (counter movement jump (CMJ) and single distance hop (SDH)) and the Lysholm score.ResultsCompared to the control group, maximal KE and KF muscle strength were impaired in the ACL reconstructed leg by 27–39% and 16–35%, respectively (p < .001). Also, impairments of both CMJ (38%) and SDH (33%) were observed (p < .001). Rate of force development for KE were reduced in the ACL group compared to the control group (p < .001). Similarly, the KE and KF muscle strength, CMJ and SDH of the ACL reconstructed leg were impaired, when compared to the non-injured leg by 15–23%, 8–20%, 23% and 20%, respectively (p < .05).ConclusionMuscle strength and functional capacity are markedly impaired in the ACL reconstructed leg of recreationally active people 9–12 months post-surgery when compared to healthy matched controls and to their non-injured leg. This suggests that objective criteria rather than “time-since-surgery” criteria should guide return to sport.  相似文献

Given scarce external validity available to date concerning the reinvestment construct, the aim of this four-study research project was to further explore the validity of the Movement-Specific Reinvestment Scale and the Decision-Specific Reinvestment Scale, using psychometric and behavioral measures. Study 1 showed that deliberative participants had a higher reinvestment tendency than intuitive participants. Study 2 showed that reinvestment was linked to self-consciousness, rumination, perfectionism, and had satisfactory test–retest reliability. Moreover, it provided some potential insights on the development of reinvestment due to parental criticisms. Study 3 indicated that high decision reinvestors performed worse than their low decision reinvestor counterparts in a visual search task under pressure. Study 4 showed that older participants had a lower reinvestment score, and that reinvestment was associated with higher motor imagery ability, challenging the idea that reinvestment can only be seen as detrimental to performance.  相似文献

Evaluative priming by masked emotional stimuli that are not consciously perceived has been taken as evidence that affective stimulus evaluation can also occur unconsciously. However, as masked priming effects were small and frequently observed only for familiar primes that there also presented as visible targets in an evaluative decision task, priming was thought to reflect primarily response activation based on acquired S–R associations and not evaluative semantic stimulus analysis. The present study therefore assessed across three experiments boundary conditions for the emergence of masked evaluative priming effects with unfamiliar primes in an evaluative decision task and investigated the role of the frequency of target repetition on priming with pictorial and verbal stimuli. While familiar primes elicited robust priming effects in all conditions, priming effects by unfamiliar primes were reliably obtained for low repetition (pictures) or unrepeated targets (words), but not for targets repeated at a high frequency. This suggests that unfamiliar masked stimuli only elicit evaluative priming effects when the task set associated with the visible target involves evaluative semantic analysis and is not based on S–R triggered responding as for high repetition targets. The present results therefore converge with the growing body of evidence demonstrating attentional control influences on unconscious processing.  相似文献

The stream of consciousness often appears whimsical and free from external control. Recent advances, however, reveal that the stream is more susceptible to external influence than previously assumed. Thoughts can be triggered by external stimuli in a manner that is involuntary, systematic, and nontrivial. Based on these advances, our experimental manipulation systematically triggered a sequence of, not one, but two involuntary thoughts. Participants were instructed to (a) not subvocalize the name of visual objects and (b) not count the number of letters comprising object names. On a substantial proportion of trials, participants experienced both kinds of involuntary thoughts. Each thought arose from distinct, high-level processes (naming versus counting). This is the first demonstration of the induction of two involuntary thoughts into the stream of consciousness. Stimulus word length influenced dependent measures systematically. Our findings are relevant to many fields associated with the study of consciousness, including attention, imagery, and action control.  相似文献

IntroductionBullying is an insidious aggressive behavior characterized by repetitiveness, imbalance of power (a bully dominating his victim) and intent to do harm. People can fall into four different categories: bully, victim, bully/victim or not involved. While numerous researchers have explored the psychopathological consequences of intimidation, few of them have studied the way students with different profiles process social information.ObjectiveThe aim of this study was to explore whether there are specific ways of processing social information in relation to the bullying profile. We refer to the theoretical model of Crick and Dodge (1994) and assume that this information will be processed differently depending on the adolescent's bullying profile.MethodSeven hundred and seventeen (717) secondary school students took part in semi-structured individual interviews and answered several questionnaires related to bullying and social information processing mechanisms.ResultsThe main results show links between social information processing mechanisms and the bullying profiles. Bullies, victims and bully/victims show biases in their social information processing mechanisms at different stages of the model.ConclusionSpecific cognitive patterns seem to exist in relation to the bullying profile. These results provide a better understanding of the way adolescents process social information and open-up new perspectives for preventing bullying in schools.  相似文献
