Creativity is being sought as a competitive edge for businesses as it has become an essential part of work. Previous creativity research focused on the creative person, process, product, and the social environment for creativity; however, recently, increasing attention towards the physical design of the workplace in promoting creative performance has emerged (Dul, Ceylan, & Jaspers, 2011). Many attributes compose the physical environment (e.g. color, lighting, spatial layout, etc.) but not many studies have investigated the relationship between physical environment attributes and creativity to date. From a review of literature, a conceptual framework was created to better understand the effects of physical environment attributes on creative performance and the mediating processes explaining the relationship. This framework identified lacunae in research and was used as a guide for conducting experiments on the effects of lighting on creative performance, in which research was particularly lacking. A series of experiments utilizing different characteristics of lighting-illuminance levels (Experiment 1), task luminance (Experiment 2), visual privacy (Experiment 3), and color temperature and lighting spectrum (Experiment 4)-investigated the effects of lighting on creative performance as measured by fluency, originality, and elaboration using the Torrance Test of Creative Thinking (TTCT). No significant differences between low and high illuminance levels were found in Experiments 1, 2, and 3, contrary to previous research (Steidle & Werth, 2013). Significant correlations were found among mood ratings (i.e. pleasure and arousal), environmental perceptions, and creative performance suggesting that certain environmental perceptions may improve creative performance. Experiment 1 and 3 showed that visual privacy improved elaboration scores but no direct effect of lighting on creative performance was demonstrated. Experiment 4 showed a diverse array of individual lighting preferences for creative work, but surprisingly, this self-selected lighting did not affect actual creative performance. Future investigations might usefully focus on other environmental design factors that might improve creative performance.
