Perspective Taking and Intergroup Helping Intentions: The Moderating Role of Power Relations1

People are more willing to help those who belong to their own groups than to an out‐group. Research on perspective taking has shown that many forms of in‐group favoritism disappear when people are led to take the perspective of the other group. The current research explores the possibility of increasing the level of intergroup helping by a perspective‐taking manipulation. An experiment in a Polish‐Czech borderland community high school demonstrated that Polish students who were made to imagine that they became members of an out‐group (perspective‐taking manipulation) were more willing to help out‐group members. The moderating role of perceived power is discussed in the context of perspective‐taking theory.     

Variety‐Seeking and Perceived Expertise

People often infer expertise from the choice of unique, rare, or sophisticated options. But might mere variety‐seeking also serve as a signal of expertise, and if so, how? Six studies show that the relationship between variety‐seeking and perceived expertise is not unidirectional and depends on the perceiver's own level of expertise. Category experts perceive lower variety‐seeking as indicative of discernment, which in turn increases perceived expertise in that category. Consequently, experts choose less variety to portray themselves as experts. In contrast, novices perceive high variety‐seeking as indicative of category breadth knowledge, which in turn increases their perception of category expertise. Consequently, novices choose more variety to portray themselves as experts. The findings make novel theoretical contributions to research on variety‐seeking, consumer expertise, and social perception, as well as practical contributions for marketers of product assortments and bundles.     

Group norms and excessive absenteeism: The role of peer referent others

Drawing from social identity and social influence theory, we propose that the absence-related norms of an individual’s work-based referent others will have a significant effect on the likelihood of excessive absence behavior. We then develop and test a model of the social mechanisms potentially underlying the relationship between referent absence norms and the likelihood of excessive absence behavior. Our findings indicate that referent group norms significantly explain excessive absence behavior, even when taking into account the absence norms associated with the formal organizational units within which these referent groups are often nested. They also indicate that permissive referent group norms are likely to have a greater impact on the probability of target excessive absence when the target has a more conformist disposition. Finally, post-hoc findings suggest that the more negative targets’ perceptions of the consequences of absenteeism, the more attenuated the impact of permissive group norms on excessive absence behavior.     

Magnetic stimulation studies of foveal representation

The right and left visual fields each project to the contralateral cerebral hemispheres, but the extent of the functional overlap of the two hemifields along the vertical meridian is still under debate. After presenting the spatial, temporal, and functional specifications of Transcranial Magnetic Stimulation (TMS), we show that TMS is particularly suitable to study the question of foveal representation as it allows one to study the effects of selective disruption of left or right hemisphere functions on the processing of centrally presented stimuli. Future strategies for the use of TMS in further tests of visual word recognition are suggested.     

Personal experience in professional narratives: the role of helpers' families in their work with terror victims

This article describes research on the narratives of social workers who help terror victims, focusing on the relationship between the helpers' families and their work. Qualitative analysis of three training groups of social workers who are responsible for helping in the event of terror attacks in different parts of Israel, and of three debriefing groups for social workers after terror attacks, reveals that the helpers' families play a role in the narratives constructed by the helpers. Two main themes were identified. The first centers on the interaction between work and the family, and shows that in the situation of a terror attack, the conflict between the two disappears and the family often serves as a support system for the helpers. The second theme refers to the family dimension alone, and focuses on the dichotomy between vitality and loss. The way that family life events affect helpers'professional intervention is described. The findings are discussed in light of Conservation of Resources Theory, the fight-flight response to threat, and the concept of the family as a source of safety and risk taking.     

Case alternation and length effects in lateralized word recognition: studies of English and Hebrew

Effects of CaSe AlTeRnAtIoN were studied in two lateralized visual lexical decision experiments. We manipulated word length and letter case (UPPER, lower and MiXeD) in both English (Exp. 1, N=60) and Hebrew (Exp. 2, N=60). The previously reported visual field and word length interaction was found for upper and lower case presentation, but not for MiXeD CaSe, where both fields were affected by word length. The effects of case alternation are discussed in light of a new lateralized word recognition theory.     

A fiery conflict: Attachment orientations and the effects of relational conflict on sexual motivation

This study examined the effects of relational conflict on sexual motivation. Sixty‐one couples were videotaped while discussing either a major relationship problem or their daily routine. Both partners then completed measures of sexual motives and rated their romantic partner's sexual attractiveness. Results showed that conflict discussion inhibited relationship‐based motives and had an adverse effect on women's perceptions of partner's attractiveness, but a beneficial effect on men's perceptions. Conflict discussion also inhibited self‐serving sexual motives such as having sex to obtain relief from stress among people with avoidant partners, suggesting that people are unlikely to turn to avoidant partners for sexual consolation. Implications for understanding the role of the sexual system in regulating reactions to relationship distressful events are discussed.     

Memory modulated saliency: A computational model of the incremental learning of target locations in visual search

The top-down guidance of visual attention is one of the main factors allowing humans to effectively process vast amounts of incoming visual information. Nevertheless we still lack a full understanding of the visual, semantic, and memory processes governing visual attention. In this paper, we present a computational model of visual search capable of predicting the most likely positions of target objects. The model does not require a separate training phase, but learns likely target positions in an incremental fashion based on a memory of previous fixations. We evaluate the model on two search tasks and show that it outperforms saliency alone and comes close to the maximal performance of the Contextual Guidance Model (CGM; Torralba, Oliva, Castelhano, & Henderson, 2006; Ehinger, Hidalgo-Sotelo, Torralba, & Oliva, 2009), even though our model does not perform scene recognition or compute global image statistics. The search performance of our model can be further improved by combining it with the CGM.
