Résumé :

Several studies have reported beneficial effects of light exposure to counteract increased sleepiness and decreasing performance. However, little is known about the role of light exposure to prevent decreases of alertness due to high cognitive demands. In the current study, we investigated the effects of bright-light exposure to prevent increases in sleepiness and decreases in alertness induced by a dual working-memory task (TloadDback) in which high cognitive load (HCL) levels can be adapted to the individual’s maximal capacity.
