Project 1

Having adequate sleep helps optimize cognitive outcomes in school-aged children. However, the features of sleep macroand micro-structure that contribute to such benefits are not well established with only a handful of cross-sectional studies linking various stages of sleep with IQ, and sleep stages, slow wave activity, and sleep spindles with executive functioning. To determine the features of sleep that are associated with neurobehavioural and psychosocial development in children, in this longitudinal study, we will track changes in polysomnographically-assessed sleep, cognitive performance, and internalizing and externalizing behaviour in children, aged 7-9 years atbaseline, over a 1-year period.

Project 2:

In this cross-sectional survey, we will uncover factors that determine children’s sleep and developmental outcomes. Specifically,we will examine the impact of sleep-related parental involvement and parenting practices on school-age children’s sleep, psychosocial, and academic outcomes (objective 1). Moreover, we will investigate the demographic profile of families with suboptimal sleep-related parenting practices in Singapore (objective 2). Data will also be collected from a US sample which will allow cross-cultural comparisons (objective 3).
