Wirkung der Farbtemperatur des Lichts auf Konzentration und Kreativität

Abstract: Light has different biological effects depending on the color temperature and intensity. This may be the reason for its differing effects. We investigated the influence of color temperature (3000 K, 4500 K, 6000 K) under constant high intensity (1000 Lux) on concentration and creativity of 50 students and employees of the Cologne University of Applied Sciences, Campus Gummersbach (age: 30.9 +/- 10.8y.). As test method we used d2-bq-test, creativity test (mean of the number of ideas on 5 themes), word test and … Show more

“…The subjective self-assessments, on the other hand, showed a decrease in concentration and an increase in stress and fatigue under daylight conditions. Weitbrecht, Bärwolff, Lischke and Jünger [9] investigated the influence of the correlated color temperature of light on concentration and creativity in n = 50 students and employees. The three light scenarios (3000 K, 4500 K, 6000 K) were given with a constant illuminance of 1000 lx in a darkened room by an LED surface area light.…”

“…Therefore, artificial daylight is used indoors, to optimize room lighting or as a specific intervention in light therapy. Although field and laboratory studies have shown positive effects of intense artificial daylight on attention in different populations and under different conditions compared to neutral and warm white light and dimmed illuminance levels [2 -9], not all investigations have yielded significant effects [9] However, these empirical findings can only be explained theoretically to a limited extent, because the mechanism of light interventions during the day are still the subject of controversy [2,8]. Even those studies that point beneficial artificial light effects [3,7] have yielded heterogeneous results on individual subscales of the frequently administered d2 test of attention [10]: Increase in the speed-based total value (KL) vs a reduction in the error rate (F).…”
