Beliefs about group malleability and out‐group attitudes: The mediating role of perceived threat in interactions with out‐group members

Recent research suggests that inducing fixed (rather than malleable) beliefs about groups leads to more negative attitudes toward out‐groups. The present paper identifies the underlying mechanism of this effect. We show that individuals with a fixed belief about groups tend to construe intergroup settings as threatening situations that might reveal shortcomings of their in‐group (perceived threat). In the present research, we measured (Study 1) and manipulated (Study 2) participants' lay theories about group malleability. We found that the extent to which individuals had an entity (versus an incremental) group theory influenced the level of threat they felt when interacting with out‐group members, and that perceived threat in turn affected their level of ethnocentrism and prejudice. These findings shed new light on the role of lay theories in intergroup attitudes and suggest new ways to reduce prejudice. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

We developed a Spanish‐language version of the Questions About Behavioral Function (QABF) utilizing a forward‐adaptation and back‐adaptation translation process. Subsequently, we administered the assessment with 80 bilingual participants to assess the reliability and validity of the instrument. Results demonstrated that the Spanish version of the QABF was both reliable (i.e., was internally consistent) and valid (i.e., identified the correct function). Implications and future research are discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Following initial encoding, memories undergo a prolonged period of reorganization. While such reorganization may occur in many different memory systems, its purpose is not clear. Previously, we have shown that recall of recent contextual fear memories engages the dorsal hippocampus (dHPC). In contrast, recall of remote contextual fear memories engages a number of different cortical regions, including the anterior cingulate cortex (ACC). To examine whether this reorganization leads to greater memory stability, we examined reconsolidation of 1 d-old (recent) and 36 d-old (remote) contextual fear memory in mice. We infused the protein synthesis inhibitor, anisomycin (ANI), into either the dHPC or ACC immediately following retrieval of either a recent or remote contextual fear memory. In the dHPC, ANI infusions disrupted subsequent expression of recent, but not remote, contextual fear memory. Similar infusions into the ACC had no effect on either recent or remote contextual fear memories, whereas systemically applied ANI blocked subsequent remote memory expression when long re-exposure durations were used. Together, these data suggest that as memories mature they become increasingly stable. Furthermore, the dissociation between the effects of systemically and centrally administered ANI on remote memory suggests that stability is due, in part, to the distributed nature of remote contextual fear memories. 相似文献
