Extant research has demonstrated the destructive role that anger plays in the context of intergroup conflict. Among other findings, it has been established that anger elevates public support for aggressive and violent actions towards the outgroup. This finding has been explained by the unique cognitive appraisals, emotional goal, and response tendencies associated with anger, typified by appraised relative strength and high control, motivation to correct perceived wrongdoings, and willingness to engage in risky behavior. In the current work we examine an innovative assumption, according to which the apparent destructive implications of anger are a result of situational range restriction—namely, that anger as a group emotion has been examined almost solely at the escalation stage of conflict. Instead, we propose that the same unique characteristics of anger can bring about constructive political attitudes and support for non-violent policies in the context of systematic efforts to de-escalate a protracted conflict.To test this hypothesis we conducted two studies in which we examined the relationship between anger and the willingness to engage in positive risk-taking and support non-violent policies in the context of political negotiations between adversaries. Results indicate a significant positive relationship, supporting the hypothesis that anger is not an exclusively militant emotion, and its effects are situationally dependent. 相似文献

In the present study, we investigate how spatial attention, driven by unisensory and multisensory cues, can bias the access of information into visuo-spatial working memory (VSWM). In a series of four experiments, we compared the effectiveness of spatially-nonpredictive visual, auditory, or audiovisual cues in capturing participants' spatial attention towards a location where to-be-remembered visual stimuli were or were not presented (cued/uncued trials, respectively). The results suggest that the effect of peripheral visual cues in biasing the access of information into VSWM depend on the size of the attentional focus, while auditory cues did not have direct effects in biasing VSWM. Finally, spatially congruent multisensory cues showed an enlarged attentional effect in VSWM as compared to unimodal visual cues, as a likely consequence of multisensory integration. This latter result sheds new light on the interplay between spatial attention and VSWM, pointing to the special role exerted by multisensory (audiovisual) cues. 相似文献

The present work investigated young children’s normative understanding of property rights using a novel methodology. Two- and 3-year-old children participated in situations in which an actor (1) took possession of an object for himself, and (2) attempted to throw it away. What varied was who owned the object: the actor himself, the child subject, or a third party. We found that while both 2- and 3-year-old children protested frequently when their own object was involved, only 3-year-old children protested more when a third party’s object was involved than when the actor was acting on his own object. This suggests that at the latest around 3 years of age young children begin to understand the normative dimensions of property rights. 相似文献

Qigong is an ancient form of health maintenance, which is part of Traditional China Medicine. Numerous beneficial mental and physical effects have been classically ascribed to this traditional psychosomatic method. The purpose of this work has been to assess the effects of Taoist qigong practice on several hormonal parameters of the Hipotalamic‐Pituitary‐Adrenal axis and specific measures of psychological well‐being in healthy subjects. Forty‐three healthy volunteers participated in the study, of whom 22 were randomly allocated to the experimental group, and 21 were assigned to the control group. Experimental participants underwent a qigong training program for one month. Blood samples for the quantification of hormonal parameters, and several instruments to assess anxiety and depression symptoms as well as subjective sleep quality, were obtained before and after the program. Statistically significant differences were found between the experimental and control groups, with the experimental group showing lower blood levels of adrenocorticotropic hormone (ACTH). This study shows that Taoist qigong is a psychosomatic method able to exert a modulatory action on ACTH levels in healthy subjects. We consider the need to continue exploring the psychobiological modulation of this qigong method and its possible repercussion for human health care. 相似文献

Over recent years, various semantics have been proposed for dealing with updates in the setting of logic programs. The availability
of different semantics naturally raises the question of which are most adequate to model updates. A systematic approach to
face this question is to identify general principles against which such semantics could be evaluated. In this paper we motivate
and introduce a new such principle the refined extension principle. Such principle is complied with by the stable model semantics for (single) logic programs. It turns out that none of the
existing semantics for logic program updates, even though generalisations of the stable model semantics, comply with this
principle. For this reason, we define a refinement of the dynamic stable model semantics for Dynamic Logic Programs that complies with the principle. 相似文献

A variety of studies suggest that a high need for closure--that is, a desire for knowledge that is clear, stable, and unambiguous as opposed to confusing or uncertain--may be associated with greater hostility toward relevant outgroups. Using international attitudes as the context, the authors examine the hypothesis that the relationship between the need for closure and support for military action against Iraq may be moderated by identification with the national ingroup. Specifically, it is expected that this relationship will be moderated by nationalism (i.e., an aggressive form of identification based on a desire for national dominance) but not patriotism (i.e., a more neutral love of one's country). The data provided a clear pattern of support for this hypothesis and additional analyses indicated that a high need for closure reduced variability about the use of force among the highly nationalistic but not the highly patriotic. 相似文献

Consolidation theory proposes that through the synthesis of new proteins recently acquired memories are strengthened over time into a stable long-term memory trace. However, evidence has accumulated suggesting that retrieved memory is susceptible to disruption, seeming to consolidate again (reconsolidate) to be retained in long-term storage. Here we show that intracortical blockade of protein synthesis in the gustatory cortex after retrieval of taste-recognition memory disrupts previously consolidated memory to a restricted degree only if the experience is updated. Our results suggest that retrieved memory can be modified as part of a mechanism for incorporating updated information into previously consolidated memory. 相似文献

The relevance of perirhinal cortical cholinergic and glutamatergic neurotransmission for taste recognition memory and learned taste aversion was assessed by microinfusions of muscarinic (scopolamine), NMDA (AP-5), and AMPA (NBQX) receptor antagonists. Infusions of scopolamine, but not AP5 or NBQX, prevented the consolidation of taste recognition memory using attenuation of neophobia as an index. In addition, learned taste aversion in both short- and long-term memory tests was exclusively impaired by scopolamine. These data provide neurochemical support for the theory that cholinergic activity of the perirhinal cortex participates in the formation of the taste memory trace and that it is independent of the NMDA and AMPA receptor activity. These results support the idea that cholinergic neurotransmission in the perirhinal cortex is also essential for acquisition and consolidation of taste recognition memory. 相似文献

Two studies examined the relationship between the need for cognitive closure and preferences for conflict-resolution strategies in 2 different samples of elite political actors. Although research has suggested that high need for closure should be associated with competitiveness, the authors argue that this relationship should be strongest among political actors with a hostile conflict schema, or representation of what a conflict is and how it should be dealt with. The authors provide evidence for this hypothesis using archival survey data on American foreign-policy officials' attitudes toward international conflict at the height of the Cold War (Study 1) and their own data on the relationship between the need for closure and conflict-strategy preferences among samples of activists from 2 political parties in Poland: a centrist party with a reputation for cooperativeness and an extremist party with a reputation for confrontation (Study 2). The broader implications of these findings are discussed. 相似文献

There is a large body of evidence suggesting that cholinergic activity is involved in memory processes. It seems that cholinergic activity is essential to learn several tasks and recent works suggest that acetylcholine plays an important role during the early stages of memory formation. In this review, we will discuss the results related to taste memory formation, focusing particularly on the conditioned taste aversion paradigm. We will first give evidence that nucleus basalis magnocellularis is involved in taste memory formation, due to its cholinergic projections. We then show that the cholinergic activity of the insular (gustatory) cortex is related to the taste novelty, and that the cholinergic signals initiated by novelty are crucial for taste memory formation. Then we present recent data indicating that cortical activation of muscarinic receptors is necessary for taste trace encoding, and also for its consolidation under certain circumstances. Finally, interactions between the cholinergic and other neuromodulatory systems inducing intracellular mechanisms related to plastic changes will be proposed as important processes underlying gustatory memory trace storage. 相似文献
