Increased realism in eyewitness confidence judgements: the effect of dyadic collaboration

This study investigated to what extent, and under what circumstances, pair collaboration influences the realism in eyewitness confidence in event memory. The participants first saw a short film clip and then confidence rated their answers to questions on its content. A condition (the Individual–Pair condition) where individual effort preceded pair collaboration showed better calibration compared with a condition (the Simple Pair condition) where no individual effort took place. Furthermore, within the Individual–Pair condition, better calibration, and lower overconfidence, were found in the pair phase compared with the individual phase. The eyewitnesses in the Individual–Pair condition made more realistic judgements of the total number of questions answered correctly. In a control experiment no effect on realism in confidence was found when individuals performed the same task twice. The improved realism in the Individual–Pair condition may partly be explained in terms of the increased accuracy and lowered confidence found for such items where the pair members' had given different answers in the individual phase, and by a risky shift effect for such items where they had given the same answer.

An Information‐processing Perspective on Leadership and Culture: A Case for Connectionist Architecture

Un mode`le de la relation entre la culture et le leadership est pre´sente´ dans cet article; ce mode`le est centre´ sur le traitement de l'information. Nous estimons qu'un re´seau connectionniste s'impose pour une bonne compre´hension de la faµon dont la culture et le leadership influencent les re´actions et la comprotement du suiveur, ce qui nous diffe´rencie des travaux ante´rieurs dans ce domaine. On examine brie`vement les structure connectionnistes en remarquant qu'il y a recouvrement entre la conceptualisation des sche´mas inclus dans ces structures et les re´flexions actuelles sur les sche´mas concernant la culture et le leadership. Ce mode`le est suffisamment souple pour expliquer les processus cognitivement efficients qui e´mergent consciemment ou subconsciemment. En outre, il peut rendre compte de la sensibilite´ a` l'information (provenant de la situation) des sche´mas du leadership et des syste`mes culturels. On traite enfin du caracte`re critique de la notion de concept de soi dans la compre´hension des processus a` travers lesquels culture et leadership interagissent pour influencer les re´action et la conduite des suiveurs.     

Integrity Tests and the Five‐Factor Model of Personality: A Review and Empirical Test of Two Alternative Positions

The psychological meaning of integrity test scores has been explored predominantly in relation to the five‐factor model of personality (FFM). Two alternative positions on this topic can be identified in the literature which state, respectively, that integrity tests measure (a) a higher‐order factor of personality covering three FFM dimensions or (b) a linear composite of numerous facets from various domains within the FFM. An empirical test of these alternative positions, using structural equation modeling, revealed that the value of both views depended on the type of integrity test examined. With a personality‐based integrity test, position (a) had to be refuted, whereas position (b) was strongly supported. There was also more supportive evidence for position (b) with an overt test, but the difference was far less pronounced than for the personality‐based measure. Possible consequences for theories on the role of personality in personnel selection are discussed.
