The goal of the current studies is to explore the conditions by which light color temperature impacts cognitive abilities and the development of this relationship. Experiments 1 and 1A explored whether exposure to light fluctuating around a central color temperature leads to increases in attention in adult participants. Results showed that, under the dynamic lighting condition, participants’ showed a significant decrease in reaction time on a measure of sustained attention, beyond those of a static light source at a cooler color temperature. Experiment 2 tested whether preschool-aged and 7-year-old participants would show increases in attention and cognitive flexibility after exposure …
