The roles of racial discrimination and sleep in the cognitive functioning of racial and ethnic minority youth.

Research suggests that chronic stress reduces cognitive functioning; however, studies examining this relationship for race-related stress, such as racial discrimination, are limited and primarily focus on older adults. Moreover, considering the importance of sleep when coping with stress, it is possible that sleep buffers the effect of racial discrimination on cognitive functioning. The present study examined the role of sleep duration and quality in the relationship between racial discrimination and cognitive functioning in early adolescence.
