We all live in Germany but … Ingroup projection,group‐based emotions and prejudice against immigrants

Immigration, cultural diversity and integration are among the most central challenges for modern societies. Integration is often impeded by negative emotions and prejudices held by the majority members towards immigrants in a common society. Based on the ingroup projection model (Mummendey & Wenzel, 1999), we examined the impact of perceived relative ingroup prototypicality on intergroup emotions and prejudice. Additionally, we examined whether this impact is causal and explored the issue of causality in more detail contrasting a linear causal model with bi‐directional or reciprocal causality. Hypotheses were tested in a study with a two‐wave panel of majority members (N=1085) in Germany. We examined the proposed relations between relative ingroup prototypicality, intergroup emotions and prejudice and determined the causal direction of these relationships. Results support the predictive power of relative ingroup prototypicality on intergroup emotions and prejudice. Moreover, most causal relations between our measures are reciprocally causal. We discuss the implications of these findings for the general conception of prejudice and intergroup emotions. Copyright © 2009 John Wiley & Sons, Ltd.     

Mechanistic Constitution in Neurobiological Explanations

This paper discusses the constitution relation within the framework of the mechanistic approach to neurobiological explanation. It develops a regularity theory of constitution as an alternative to the manipulationist theory of constitution advocated by some of the proponents of the mechanistic approach. After the main problems of the manipulationist account of constitution have been reviewed, the regularity account is developed based on the notion of a minimal type relevance theory. A minimal type relevance theory expresses a minimally necessary condition of a given type that consists of a disjunction of minimally sufficient conditions of that type. Afterwards, the attained definition is successfully applied in an analysis of the logical structure of the explanation of spatial learning and memory in rats as a paradigm neurobiological explanation. The overall result is a more robust and more precise version of the mechanistic approach to neurobiological explanations.     

Hemispheric specialization and creative thinking: A meta-analytic review of lateralization of creativity

In the last two decades research on the neurophysiological processes of creativity has found contradicting results. Whereas most research suggests right hemisphere dominance in creative thinking, left-hemisphere dominance has also been reported. The present research is a meta-analytic review of the literature to establish how creative thinking relates to relative hemispheric dominance. The analysis was performed on the basis of a non-parametric vote-counting approach and effect-size calculations of Cramer’s phi suggest relative dominance of the right hemisphere during creative thinking. Moderator analyses revealed no difference in predominant right-hemispheric activation for verbal vs. figural tasks, holistic vs. analytical tasks, and context-dependent vs. context-independent tasks. Suggestions for further investigations with the meta-analytic and neuroscience methodologies to answer the questions of left hemispheric activation and further moderation of the effects are discussed.     

Identification and location tasks rely on different mental processes: a diffusion model account of validity effects in spatial cueing paradigms with emotional stimuli

Spatial cueing paradigms are popular tools to assess human attention to emotional stimuli, but different variants of these paradigms differ in what participants’ primary task is. In one variant, participants indicate the location of the target (location task), whereas in the other they indicate the shape of the target (identification task). In the present paper we test the idea that although these two variants produce seemingly comparable cue validity effects on response times, they rest on different underlying processes. Across four studies (total N?=?397; two in the supplement) using both variants and manipulating the motivational relevance of cue content, diffusion model analyses revealed that cue validity effects in location tasks are primarily driven by response biases, whereas the same effect rests on delay due to attention to the cue in identification tasks. Based on this, we predict and empirically support that a symmetrical distribution of valid and invalid cues would reduce cue validity effects in location tasks to a greater extent than in identification tasks. Across all variants of the task, we fail to replicate the effect of greater cue validity effects for arousing (vs. neutral) stimuli. We discuss the implications of these findings for best practice in spatial cueing research.     

Taking a new look at looking at nothing

A crucial question in cognitive science is how linguistic and visual information are integrated. Previous research has shown that eye movements to objects in the visual environment are locked to linguistic input. More surprisingly, listeners fixate on now-empty regions that had previously been occupied by relevant objects. This 'looking at nothing' phenomenon has been linked to the claim that the visual system constructs sparse representations of the external world and relies on saccades and fixations to extract information in a just-in-time manner. Our model provides a different explanation: based on recent work in visual cognition and memory, it assumes that the visual system creates and stores detailed internal memory representations, and that looking at nothing facilitates retrieval of those representations.     

Effects of Transactional and Transformational Leadership of Pastors

Over the last 20 years, researchers and practitioners have become increasingly interested in the transactional–transformational leadership paradigm. However, only a few studies have tested the validity of this approach to leadership concerning Christian pastors. Thus, two studies were conducted in Germany that explored the effect of transactional and transformational leadership of pastors on several outcome criteria. The results revealed that transformational leadership was positively associated with followers’ satisfaction with their pastor, their extra effort, their effectiveness, and their job satisfaction. In addition to this effect on followers, transformational leadership showed positive effects on worshipers’ satisfaction with the worship service. Implications of these results for theory and practice are discussed.

Implicit person theories influence memory judgments: the circumstances under which metacognitive knowledge is used

This work focuses on the influence of implicit theories on recognition judgments. We argue that to understand how a recognition task is solved, it is necessary to study inferential processes because individuals might use their metamnestic knowledge (‘I would have known that!’) as a basis for replacing missing recollective experiences with inferential processes (Strack & Bless, 1994 ). In the present study, individuals' preexisting implicit personality theory (Dweck, 1996 ) was measured and was identified as a moderating variable for the use of metamnestic knowledge. After participants had studied word lists their metamnestic knowledge concerning these lists was manipulated. The results of a subsequent recognition task revealed that individuals used these metacognitively based inferences only when they assumed personal stability (‘entity theory’). Participants who believed in personal variability (‘incremental theory’) did not draw similar inferences when recollective experiences were missing. Copyright © 2002 John Wiley & Sons, Ltd.
