Other work demonstrates that adequate amounts of sleep reduce racial and social differences on cognitive tests. When schoolchildren from different ethnic and social groups get adequate amounts of sleep, their performance on Woodcoc k-Johnson tasks is similar. When sleep is disrupted, traditional performance differences between racial and social status groups appear on these cognitive tasks. The performance of European Americans and high social status groups is less affected by decreased sleep than that of African American and lower social status children. Helping children develop healthy sleep habits is a critical task for parents not only because poor sleep patterns are associated with lack of alertness, poor attention span, and poor memory as well as learning problems, but because sleep problems are also associated with emotional problems such as aggressiveness and depression as well.
