When Small Means Comfortable: Relations Between Product Attributes in Two‐Sided Advertising

The processes that mediate the effectiveness of 2‐sided advertising were studied. We predicted that (a) 2‐sided (vs. 1‐sided) advertisements increase perceived source credibility and that (b) the logical relation between the negative and positive product attributes mentioned in the 2‐sided ad (e.g., little space, implying a cozy atmosphere) facilitates favorable inferences about the positive attributes, especially when recipients have sufficient time to process the message content. Results supported these predictions. However, the effects of message type and processing time on attitudes were mediated by inferences about positive attributes but not by perceived source credibility. Implications of these findings for consumer judgment and decision making are discussed.     

Constructing Gender: A Lens-Model Inspired Gender Communication Approach

In this experiment (n=115), I followed a lens-model approach (Brunswik, 1956) to investigate the communicative construction of gender. For this purpose, a situation was created in which gender was not clearly visible and thus existed mainly as a gender-assumption in the eye of the beholder. The study featured the perception of a team leader during a team-meeting presented in a masked video-clip and either labeled as Mr. K or Mrs. K (Goldberg-paradigm study). Results suggested that the assumption of the leader's gender (gender-assumption) had a systematic impact on trait-ratings of the leader in the unexpected direction that “women” were rated higher on agentic traits than “men.” This was interpreted as an expectancy-based double-standard effect in leadership perception on the basis of nonverbal cue utilization. Furthermore, differences in the predictive values of syntactic, semantic, and pragmatic cues were suggested in the analysis of verbal cue utilization. Overall, the lens-model perspective provides a useful framework by making perceptual and behavioral processes of gender construction more transparent.     

The relationship between high performance and knowledge about how to master cooperation situations

This paper applies the expertise approach to cooperation settings and examines high performers' knowledge about cooperation situations. We argue that high performers know more about how to address cooperation situations than do moderate performers. Specifically, we assume that they know more about problem analysis, about how to address the task, the cooperation partner and the cooperation partners' task approach. We report findings of two empirical studies in which study participants responded to scenario situations. The first study based on a sample of 39 software professionals showed that high performers were superior with respect to overall knowledge and specific knowledge aspects. The second study based on a sample of 62 engineers partially replicated these findings. High performers' better knowledge of cooperation situations could not be explained by years of experience or perspective taking. However, situation‐specific experiences partially accounted for the relationship between performance level and knowledge. Copyright © 2002 John Wiley & Sons, Ltd.     

The efficacy of a short version of a cognitive-behavioral treatment followed by booster sessions for binge eating disorder

This waitlist-controlled study evaluated the efficacy of a short version of a group CBT for BED followed by booster sessions after the active treatment phase. Thirty-six females with BED were randomly assigned to CBT (eight weekly sessions during active treatment plus five booster sessions during follow-up) or a waitlist condition. At the end of the active treatment, binge eating was significantly reduced relative to waitlist. Furthermore, at 12-month follow-up short-term CBT produced significant improvements in binge eating symptoms relative to baseline. Findings suggest that the short-term CBT followed by booster sessions may provide a valuable treatment option for patients with BED.     

Individual differences in conflict-monitoring: testing means and covariance hypothesis about the Simon and the Eriksen Flanker task

Conflict and context slow-down have been proposed as indicators of a conflict-monitoring system that initiates cognitive control to resolve conflicts in information processing. We investigated individual differences in conflict-monitoring and their associations with working memory (WM) and impulsivity. A total of 150 adults completed a Simon and an Eriksen flanker task, together with measures of WM and impulsivity. On both tasks, responses were slower and less accurate on incompatible than on compatible trials (conflict effect), and the conflict effect was larger when the preceding trial was compatible than when it was incompatible (context effect). Stimulus repetition did not explain the context effect. Individual differences could be attributed to three separable factors for each task: general speeded performance, conflict effect, and context effect. Evidence for across-task generality of these factors was sparse. Associations of these factors with impulsivity were weak at best. WM was correlated with general speed, and also with some but not all factors reflecting conflict-related processes.

Interlimb coordination: Learning and transfer under different feedback conditions

The role of intrinsic and extrinsic information feedback in learning a new bimanual coordination pattern was investigated. The pattern required continuous flexion-extension movements of the upper limbs with a 90 ° phase offset. Separate groups practiced the task under one of the following visual feedback conditions: (a) blindfolded (reduced FB group), (b) with normal vision (normal FB group), or (c) with concurrent relative motion information (enhanced FB group). All groups were subjected to three different transfer test conditions at regular intervals during practice. These tests included reduced, normal vision, and enhanced vision conditions. Experiment 1 showed that the group receiving augmented information feedback about its relative motions in real-time produced the required coordination pattern more successfully than the remaining two groups, irrespective of the transfer conditions under which performance was evaluated. Experiment 2 replicated and extended the superiority of the enhanced feedback group during acquisition and retention. Experiment 3 demonstrated that successful transfer to various transfer test conditions was not a result of test-trial effects. Overall, the data suggest that the conditions that optimized performance of the coordination pattern during acquisition also optimized transfer performance.     

Child Age and Planum Temporale Asymmetry

Investigations using in vivo magnetic resonance (MR) morphometry have shown that left-right asymmetry of the planum temporale (PT) is a structural correlate of hemispheric functional asymmetries in adult humans (e.g., handedness, language representation). Postmortem studies of brains of fetuses and newborns have demonstrated that PT asymmetry becomes visible as early as in the last gestational trimester. The same studies could not clarify when the full (adult) degree of PT asymmetry is reached during brain development and whether this process may be influenced by functional specialization during childhood. We examined 61 neuropsychiatrically normal right-handed children aged 3 to 14 years (mean age +/-SD, 8.4 +/- 2. 7 years; cross-sectional study). MR morphometry showed no change in PT or planum parietale asymmetry with increasing age or brain volume. An unexpected gender difference of unknown significance emerged, with girls displaying a stronger leftward PT asymmetry, independently of age. For the age range studied, the results suggest that functional differentiation follows a structural asymmetry that is already "preset." Copyright 1999 Academic Press.
