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.

Conditions
Outcome Measures
Primary Outcomes (1)
Overnight sleep physiology
Amount of slow wave activity and other non-REM sleep features in overnight sleep following a day where a nap was involved compared to when there was no nap earlier in the day.
9-11 hours of sleep overnight
Secondary Outcomes (1)
Change in memory accuracy
2-3 hours/24 hours
Study Arms (2)
Declarative memory
EXPERIMENTALNapping v. wake effect on declarative memory in habitual and non-habitual nappers.
Overnight Physiology
EXPERIMENTALNapping v. wake effect on overnight physiology in habitual and non-habitual nappers.
Interventions
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.
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.
Eligibility Criteria
You may qualify if:
- Family lives within 30 miles of UMass Amherst
- Is 33-71 months at the time of enrollment
- Meets the definition of a habitual (5+ naps/week) or non-habitual (\<2 naps/week) napper
- Normal or corrected-to-normal vision and hearing
- Access to a computer with an internet connection for online sessions with the research team.
You may not qualify if:
- Diagnosis of any sleep disorder (other than mild parasomnia which is routine at this age) past or present
- Current use of psychotropic or sleep-altering medications
- Traveling beyond 1 time zone within 1 month of participation
- Fever or symptoms of respiratory illness at the time of participation
- Diagnosed developmental disability
