Exposing information sharing as strategic behavior: power as responsibility and “Trust” buttons

Online platforms' success depends on individual's information sharing (IS). However, previous research showed that “knowledge is power” is a default‐perception in organizations and that individuals share relatively unimportant information while keeping the important private information for themselves. Trust has also been identified as important enabler of IS. We examined the role of power construed as responsibility for others' outcomes and of a “Trust” button, a theory‐inspired technological feature, using a 2(Power construals: opportunity vs. responsibility) × 2(Buttons: “Like” vs. “Like‐or‐Trust”) × 2(Information sharedness as within‐subjects factor; public, private) design. Findings showed that construing power as responsibility and “Trust” button's presence increased the sharing of private information; clicking behavior yielded insights into the underlying mechanisms. Theoretical and practical implications are discussed.     

Do observers like curvature or do they dislike angularity?

Humans have a preference for curved over angular shapes, an effect noted by artists as well as scientists. It may be that people like smooth curves or that people dislike angles, or both. We investigated this phenomenon in four experiments. Using abstract shapes differing in type of contour (angular vs. curved) and complexity, Experiment 1 confirmed a preference for curvature not linked to perceived complexity. Experiment 2 tested whether the effect was modulated by distance. If angular shapes are associated with a threat, the effect may be stronger when they are presented within peripersonal space. This hypothesis was not supported. Experiment 3 tested whether preference for curves occurs when curved lines are compared to straight lines without angles. Sets of coloured lines (angular vs. curved vs. straight) were seen through a circular or square aperture. Curved lines were liked more than either angular or straight lines. Therefore, angles are not necessary to generate a preference for curved shapes. Finally, Experiment 4 used an implicit measure of preference, the manikin task, to measure approach/avoidance behaviour. Results did not confirm a pattern of avoidance for angularity but only a pattern of approach for curvature. Our experiments suggest that the threat association hypothesis cannot fully explain the curvature effect and that curved shapes are, per se, visually pleasant.     

The magic of collective emotional intelligence in learning groups: No guys needed for the spell!

Using a cross‐lagged design, the present study tests an integrative model of emergent collective emotions in learning groups. Our results indicate that the percentage of women in the group fosters the emergence of collective emotional intelligence, which in turn stimulates social integration within groups (increases group cohesion and reduces relationship conflict) and the associated affective similarity, with beneficial effects for group effectiveness.
