Question

Quizplus · Accepted Answer

Studies have shown that lower quality sleep in infancy (such as frequent night wakings) are related to lower attention regulation and behavioral issues by three to four years of age, suggesting a link between sleep during infancy and cognitive development. Too much sleep (choice A) or a significant reduction in sleep (choice C) have not been found to have a positive impact on cognitive development. Choice D is also incorrect as the brain continues to develop throughout childhood and adolescence.
