Acute effects of lighting color temperature on mental effort and associated cardiovascular response

Abstract: Higher correlated color temperature of light contains a higher proportion of short- wavelength light and is associated with higher alertness state. Based on motivational intensity theory by Brehm, we predicted that this lighting-induced alertness state should inform about the readiness to perform and this way influence subjective task demand and thus mental effort investment. We tested these predictions of in a set of experimental studies. Effort was quantified as changes in beta-adrenergic sympathetic nervous system impact on the heart. The results show that spectral properties of light can influence mental effort mobilization.
