Post-event Processing in Children with Social Phobia

In the aftermath of a distressing social event, adults with social phobia (SP) engage in a review of this event with a focus on its negative aspects. To date, little is known about this post-event processing (PEP) and its relationship with perceived performance in SP children. We measured PEP in SP children (n = 24) and healthy controls (HC; n = 22), aged from 8 to 12 years, after the Trier Social Stress Test for Children (TSST-C). Children also rated their performance immediately after the TSST-C and 2.5 h later. SP children reported more negative and less positive PEP than controls. Regression analyses indicated that negative PEP was associated with social anxiety and perceived task performance independent of comorbid depression. The SP group rated their performance immediately after the TSST-C as worse compared to HCs and ratings remained stable over the following 2.5 h. Results are discussed in relation to current theories of SP.     

The influence of approach and avoidance motor actions on food intake

Two experiments explored the effect of arm positions of approach and avoidance on food intake. In Experiment 1, arm extension, an expression of avoidance behavior, led to smaller food intake than arm flexion, an expression of approach behavior. In Experiment 2, this effect was found only for a delicious drink (i.e. orange juice), but not for a neutral drink (lukewarm water). Different theoretical accounts for explaining the findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Optimization of Social Structure in Business Networks by Grid-Technique and Polyhedral Analysis

This article deals with the definition and analysis of the social, communicative, and cognitive abilities of managers acting in network contexts. We can tackle the complex relationship of role demands and role adoption by applying grid-technique and polyhedral analysis. We can gather data on context-specific personal constructs with the help of the grid technique. Using these data, polyhedral analysis shows how defined persons are integrated into the relation structures within a network. Beyond this, we show if and how relevant criteria such as holes, connectivity, and eccentricity can be employed for analyzing problems stemming from personnel management. Based upon the applied methods, it is possible to provide information about the relevant structures within networks used in personnel selection and competency development. Decision makers have the task to select among the measures of personnel management. Within the relevant context, these measures should be suited to ensure the stability and efficiency of the network.     

Inferences from decision difficulty

We propose that people infer the relative attractiveness of the choice alternatives from decision difficulty. A difficult decision signifies that the alternatives are close to each other in attractiveness, and an easy decision signifies that the alternatives are remote from each other in attractiveness. In Study 1, observers used reported decision difficulty to infer preferences of the decision maker. Studies 2-4 showed that inferences about the source of one’s own decision difficulty may affect a decision maker’s preferences. Study 4 integrates the notion of inferences from decision difficulty with dissonance theory, showing that in repeatable decisions difficulty reduces post-decisional spreading of alternatives, as predicted by our model, whereas with one-time decisions, difficulty enhances post-decisional spreading of alternatives, as predicted by dissonance theory.     

Enactment of approach and avoidance behavior influences the scope of perceptual and conceptual attention

In this study, we tested the hypothesis, derived from the theorizing of Derryberry and Tucker (1994), that the mere enactment of approach or avoidance behavior, without concomitant pursuit of personal approach or avoidance goals, can independently moderate the scope (i.e., breadth or narrowness) of attention on both the perceptual and conceptual levels. Specifically, we predicted that enactment of approach behavior would broaden attentional scope, engendering a focus upon global perceptual structure and facilitating conceptual access to mental representations with lower a priori accessibility, whereas enactment of avoidance behavior would constrict attentional scope, engendering a focus upon local perceptual details and “choking off” conceptual access to mental representations with lower a priori accessibility. These hypotheses were borne out in three experiments, using two different manipulations of approach vs. avoidance actions.     

Automatic effects of deviancy cues on creative cognition

Three experiments test the existence of an automatic deviancy‐creativity link. Using a lexical decision task, in Experiment 1 we found a semantic link between deviancy and creativity words in that decision times for creativity‐related words were enhanced after subliminal deviancy priming. In Experiment 2, participants were led to think about either a punk or an engineer and afterwards were administered creative insight and analytical reasoning problems. According to a pretest, punks and engineers were judged as differing in uniqueness but not in creativity. Participants given ‘punk’ priming solved more creative insight problems and fewer analytical reasoning problems than those given ‘engineer’ priming. In Experiment 3, participants were incidentally exposed to abstract artworks symbolically expressing either the concept of conformity or deviancy and were subsequently asked to solve a creative generation task. Exposure to the artwork representing deviancy led to generation of more creative solutions than exposure to that representing conformity. Copyright © 2005 John Wiley & Sons, Ltd.     

Effects of motivational cues on perceptual asymmetry: implications for creativity and analytical problem solving

In 4 experiments, participants were led to focus on either the prospect of positive outcomes (approach anticipation) or the prospect of negative outcomes (avoidance anticipation) and were subsequently administered behavioral measures of relative hemispheric activation. It was found that approach, relative to avoidance-related anticipatory states, produced greater relative right (diminished relative left) hemispheric activation. Experiment 3 additionally demonstrated that this pattern of activation was reversed when approach and avoidance states were not merely anticipatory but were also emotionally arousing. Finally, Experiment 4 replicated earlier findings demonstrating an influence of approach and avoidance anticipatory states on creativity and analytical problem solving (R. S. Friedman & J. Forster, 2001, 2003) and provided evidence that such effects are mediated by differences in relative hemispheric activation.     

Grammatical gender in spoken word recognition in German

The role of grammatical gender for auditory word recognition in German was investigated in three experiments and two sets of corpus analyses. In the corpus analyses, gender information reduced the lexical search space as well as the amount of input needed to uniquely identify a word. To test whether this holds for on-line processing, two auditory lexical decision experiments (Experiments 1 and 3) were conducted using valid, invalid, or noise-masked articles as primes. Clear gender-priming effects were obtained in both experiments. Experiment 2 used phoneme monitoring with words and with pseudowords deviating from base words in one or more phonological features. Contrary to the lexical decision latencies, phoneme-monitoring latencies showed no influence of gender but did show similarity mismatch effects. We argue that gender information is not utilized early during word recognition. Rather, the presence of a valid article increases the initial familiarity of a word, facilitating subsequent responses.
