Die Umgebungstemperatur übt einen vielfältigen Einfluss auf Gesundheit, Wohlbefinden und Leistungsfähigkeit des Menschen aus. Durch die zunehmende Verlagerung von Arbeitsplätzen in Büros rückt der Bereich der moderaten Wärmebelastung, wie er beispielsweise in natürlich belüfteten Gebäuden im Sommer auftritt, in den Fokus. Hierzu ist aus der bisherigen empirischen Forschung ein Zusammenhang zwischen Raumtemperatur und Arbeitsleistung ermittelt worden, der allerdings verschiedene Nachteile für die Tauglichkeit als Planungskriterium für Gebäude aufweist. Der in der Psychologie weit verbreitete Ansatz der Meta-Analyse kann dabei einen wertvollen Beitrag zur Lösung dieses Problems leisten. In dem Beitrag wird systematisch die Methode der Meta-Analyse aufgezeigt und anhand einiger konkreter Beispiele das Potential für eine Integration von nutzerbasierten Verhaltensmustern in eine Gebäudesimulation dargestellt.
Employee creativity is critical to organizational competitiveness. However, the potential contribution made by the workspace and the physical environment is not fully taken into account because, up to now, it has been rather unclear how aspects of the physical environment, especially light, can support creativity. Consequently, in six studies, the present research investigated the effect of light and darkness on creative performance. We expected that darkness would offer individuals freedom from constraints, enabling a global and explorative processing style, which in turn facilitates creativity. First, four studies demonstrated that both priming darkness and actual dim illumination improved creative performance. The priming studies revealed that the effect can occur outside of people's awareness and independent of differences in visibility. Second, two additional studies tested the underlying mechanism and showed that darkness elicits a feeling of being free from constraints and triggers a risky, explorative processing style. As expected, perceived freedom from constraints mediated the effect of dim illumination on creativity. Third, moderation analyses demonstrated the effects' boundary conditions: the darkness-related increase in creativity disappeared when using a more informal indirect light instead of direct light or when evaluating ideas instead of generating creative ideas. In sum, these results contribute to the understanding of visual atmospheres (i.e. visual messages), their importance for lighting effects, and their impact via conceptual links and attentional tuning. Limitations as well as practical implications for lighting design are discussed
Grounded and embodied cognitions have gained increasing interest in explaining the effects of the physical environments on social cognition and behavior. However, the very nature of the processes underlying embodiment is largely unknown. The current research aims at contributing to this issue by (1) differentiating between the embodiment of contents and procedures, (2) unfolding the processes underlying mechanism of an embodied procedure, and (3) showing its boundary conditions. Seven experiments investigated these refinements using the examples of darkness, self-construal, and cooperation in social dilemmas. The results provided consistent evidence that darkness triggers interdependent self-construal, which in turn promotes cooperation. Moreover, the individual's internal context and external context moderated the darkness-cooperation effect. These results contribute to the understanding of embodied and situated social cognition and behavior and provide a consistent explanation for the mixed findings of lighting on cooperation in particular and prosocial behavior in general.
Not Motivated to Act During Goal Pursuit: Powerlessness Blocks Motivation Transfer in Goal Systems
(2013)
The current research investigates a motivational mechanism that contributes to the inferior goal striving and attainment of powerless individuals: the transfer of motivation from goals to means. We expected that this mechanism would work effectively only in powerful individuals. The results of an experiment and a field study confirmed our assumptions. The more motivated powerful people were to attain the goals, the more they engaged in self-determined action and, in turn, the more positively they experienced goal-related activities. No such relation was found for their powerless counterparts. Implications for power research and goal systems theory are discussed.
