Ostracism—being ignored and excluded—threatens the basic human needs for belonging, self‐esteem, control, and meaningful existence. This work introduces belonging to a majority as a buffer against the immediate negative impact of ostracism on basic needs for individuals with a high need to belong, for whom social groups are especially relevant. Three studies show that for individuals high in the need to belong, need threat was attenuated by membership in a majority group, but not by membership in a minority group (Studies 1 and 3) or a group of unknown size (Study 2). By contrast, individuals low in the need to belong—who place less importance on group membership in general—did not benefit from belonging to a majority group. The general pattern replicated across different manipulations of group membership and social exclusion, with two measures of need threat, and with participants from two different countries. 相似文献

Anticipatory anxiety plays a major role in the etiology of panic disorder. Although anticipatory anxiety elicited by expectation of interoceptive cues is specifically relevant for panic patients, it has rarely been studied. Using a population analogue in high fear of such interoceptive arousal sensations (highly anxiety sensitive persons) we evaluated a new experimental paradigm to assess anticipatory anxiety during anticipation of interoceptive (somatic sensations evoked by hyperventilation) and exteroceptive (electric shock) threat. Symptom reports, autonomic arousal, and defensive response mobilization (startle eyeblink response) were monitored during threat and matched safe conditions in 26 highly anxiety sensitive persons and 22 controls. The anticipation of exteroceptive threat led to a defensive and autonomic mobilization as indexed by a potentiation of the startle response and an increase in skin conductance level in both experimental groups. During interoceptive threat, however, only highly anxiety sensitive persons but not the controls exhibited a startle response potentiation as well as autonomic activation. The anticipation of a hyperventilation procedure thus seems a valid paradigm to investigate anticipatory anxiety elicited by interoceptive cues in the clinical context. 相似文献

Odor enrichment enhances rats’ ability to discriminate between chemically similar odorants. We show here that this modulation of olfactory perception is accompanied by increases in the density of local inhibitory interneuron expressing Zif268 in response to olfactory stimuli. These changes depend on the overlap of the olfactory bulb activation patterns induced by the enrichment odorants with those induced by the testing odorants, in a manner similar to changes in perception. Moreover, we show that enrichment leads to an alteration of the pattern of Zif268 expression, dependent on the odors used for the enrichment indicating a restructuring of odor representation in the olfactory bulb. 相似文献

Self-report surveys and behavioral tasks indicate greater risk-taking behavior in adolescents as compared with adults. However, the underlying causes of these behavioral differences remain unclear. The present study examined the possibility that adolescents may be more susceptible to immediate positive and negative outcomes than adults. We compared the behavior of adolescents and adults on a modified version of the Balloon Analogue Risk Task (Lejuez et al., 2002). The task required that participants press a button to "inflate" a series of balloons on a computer screen. Balloons inflated until either the participant released the button ("saved" balloons) or the balloon "burst." Accumulated points increased as the duration of the buttonpress increased; however, simultaneously, the likelihood that the balloon would burst also increased. Adolescents inflated balloons to a larger size prior to saving them than adults did, suggesting relatively higher levels of risk taking, although the adolescents' behavior was not uniformly risk prone. Further, in comparison with adults, behavior in adolescents was more influenced by whether a balloon was saved or had burst on the preceding trial, suggesting that sensitivity to immediate consequences is one mechanism that underlies the observed difference in risk taking. 相似文献

This study investigates the comprehension of a dosage according to the desired aim before reading. The results of the two experiments carried out indicate that only the cognitive activities underlying the performance of the instructions (versus comprehension/memorisation) require the transformation of the declarative representation into a procedural one. The inferences generated attest a result/procedure relation and a hierarchical organisation of the planification of actions brought into play. Moreover, information which is directly goal‐related receives more extensive treatment than other information. 相似文献

The effects of brief mother–infant psychotherapies (maximum of 10 sessions) were examined in cases of functional and behavioral disturbances in children less than 30 months old. Seventy-five mother-infant dyads were assessed prior to treatment, at 1 week, and 6 months after therapy ended. The outcome measures were changes in the infant's symptoms, the behavioral interactions between mother and infant, and maternal representations. The effect of two forms of intervention—Psychodynamic Therapy and Interaction Guidance Therapy—were compared. Results indicated a significant symptom reduction; dyadic interactions became more harmonious (mothers became less intrusive and infants more cooperative). Maternal self-esteem grew significantly and negative affects decreased. Improvements lasted as least several months, with some positive improvement detected at the 6-month follow-up. No major difference in outcome was found between the effects of the two forms of intervention. Within the limitations of research in a clinical context, this study suggests that brief mother–infant psychotherapies are a cost-effective method of early intervention. 相似文献

We studied the time course of material categorization in natural images relative to superordinate and basic-level object categorization, using a backward-masking paradigm. We manipulated several low-level features of the images—including luminance, contrast, and color—to assess their potential contributions. The results showed that the speed of material categorization was roughly comparable to the speed of basic-level object categorization, but slower than that of superordinate object categorization. The performance seemed to be crucially mediated by low-level factors, with color leading to a solid increase in performance for material categorization. At longer presentation durations, material categorization was less accurate than both types of object categorization. Taken together, our results show that material categorization can be as fast as basic-level object categorization, but is less accurate. 相似文献

Chronic pain has previously been defined as lasting longer than 3 or 6 months. This criterion, however, does not adequately describe the process of pain becoming chronic. Consequently, pain chronicity is not only assessed by pain duration but by consideration of other factors, such as disability or intensity. A number of learning processes affect pain chronicity as they mediate changes in neural networks involved in pain processing. Furthermore, a number of psychosocial risk factors have been identified that affect not only the transition from acute to chronic pain but also the maintenance of chronic pain. The fear-avoidance model takes into account many of these risk factors to explain the development and maintenance of chronic musculoskeletal pain. 相似文献

Communication serves as an integral part of every psychotherapeutic treatment. Consequently, in the last decade modern information and communication technologies in the therapeutic context gained in importance. How important are Internet-based therapeutic information and intervention sources for potential patients and how are they appraised when already known or used? In the course of a representative study the health-related Internet use behavior of 2,411 Germans was examined. There was a focus on the usage of health-related websites and counseling services in the past and (potentially) in the future. More than one third (37.3%) of the German population and almost two thirds (63.5%) of German Internet users search for medical information on Internet. However, physicians, psychologists, pharmacists, family members and friends have a greater impact on health behavior than the Internet. Of German Internet users 54.1% are not informed about the possibilities of psychosocial online counseling. Nevertheless, they would maybe use the Internet in the future. The 2.2% who already used Internet in case of psychosocial problems are content with the service. In fact new media have not yet found their way into psychotherapy and counseling as much as in our daily lives. With regard to manifest mental disorders, Germans would prefer the conventional psychotherapeutic milieu to media-assisted kinds of treatment. 相似文献
