: Previous longitudinal studies have demonstrated prospective relationships between maternal sleep quality and subsequent psychological distress in the postpartum period. Despite evidence for prospective relationships between mood and subsequent sleep quality in adult populations, this direction has not been examined in postpartum women. We aimed to test prospective relationships between sleep quality and subsequent psychological distress, as well as the plausible reverse possibility, in a sample of Black American postpartum mothers ( = 146).

Background: The Theory of Optimal Stimulation (Zentall & Zentall, Psychological Bulletin, 94, 1983, 446) posits that the relation between activity level (AL) and cognitive performance follows an inverted U shape where midrange AL predicts better cognitive performance than AL at the extremes.
Methods: We explored this by fitting linear and quadratic models predicting mental development from AL assessed via multiple methods (parent ratings, observations, and actigraphs) and across multiple situations (laboratory play, laboratory test, home) in over 600 twins (2- and 3-year olds).
Results: Only observed AL in the laboratory was curvilinearly related to mental development scores.
