Research Design Connection: Light Color and Mental Effort Intensity
Lasauskaite and Cajochen linked mental effort intensity and light color. The team “tested effort-related cardiac response under four lighting conditions and found that it decreased with color temperatures [i.e., as light got bluer]. Thus, blue-enriched light in offices and schools might…preserve resources during cognitive activities.”
