Sleep Laboratory


The research carried out by members of our laboratory aims to study the impact of sleep disturbances on the functioning of the individual, on a psychological, emotional, cognitive and social level. Research projects at the laboratory aim to better understanding the role of sleep and the impact of sleep deprivation on the cognitive, psychological and social mechanisms that may underlie social judgments-related behaviors, speed of decision, perceptual mechanisms related to the recognition of facial expressions of emotions, sensitivity to ethnic stereotypes, food intake and energy expenditure. Other work specifically related to the interaction between sleep, child development and family functioning or the relationship between adolescents sleep difficulties and school performance, school motivation and sports performance.
