Study Details

Brief summary:

The goal of this research is to understand the role of sleep on memory function in early childhood. Specifically, we seek to examine how promoted naps vs. promoted waking in habitual and non-habitual napping children may impact overnight sleep physiology and subsequent memory consolidation.

Interventions and Outcome Measures

Arms

experimental: Declarative memory

Napping v. wake effect on declarative memory in habitual and non-habitual nappers.

experimental: Overnight Physiology

Napping v. wake effect on overnight physiology in habitual and non-habitual nappers.

Interventions

Nap/wake conditions on memory

Habitual and non-habitual napping children will complete a two conditions-a nap condition where they are encouraged to nap in the afternoon and a wake condition where instead of napping, they spend an equal amount of time awake engaging in quiet activities.

Nap/wake conditions on overnight physiology

Habitual and non-habitual napping children will complete a two conditions-a nap condition where they are encouraged to nap in the afternoon and a wake condition where instead of napping, they spend an equal amount of time awake engaging in quiet activities. On the nights of the nap and wake conditions, physiology will be recorded in habitual and non-habitual nappers.

Primary outcome measure

  • Overnight sleep physiology [ Time Frame: 9-11 hours of sleep overnight ]
