What the study is about

This study is designed to investigate developmental changes in naps and nap function on memory from 9 to 15 months of age. Memory is measured by a task in which the experimenter interacts with a toy and the measure of memory is whether the child imitates that action when given the toy. Sleep is assessed with a watch that detects motion which provides an estimate of sleep and a set of electrodes placed on the head that measures brain activity during sleep. Infants are recruited at 9 months and sleep and memory are measured again 3- and 6-months later. At each visit, memory is tested before and after a nap (either the morning or afternoon nap) and naps are recorded with the sleep electrodes.

Being studied: Nap; Wake

Conditions: Sleep Deprivation

Show full criteria

Inclusion Criteria

  • 9 months at the time of enrollment
  • normal birthweight (5.5 to 10 lbs) and gestational length (36-41 weeks)
  • must be willing and able to return for testing in 3 and 6 months (e.g., no plans to move out of the area)

Exclusion Criteria

  • born premature (\<36 weeks gestational age)
  • receiving services due to developmental delays
  • visual or motor disability
  • score \<85 on cognitive and language composite scales and/or \<80 on the average of the two composites of the Bayley Scales of Infant Development Fourth Edition (BSID-IV) administered at the first session.
  • Infants' motor development (gross and fine motor) will also be assessed using the BSID-IV, and an adjusted cutoff of 73 will be used to exclude infants with significant motor delays (given the motoric nature of the task).
  • traveling beyond 1 time zone within 2 weeks prior to testing (phone screening)
  • fever or symptoms of respiratory illness at the time of testing (phone screening)
  • physical handicap that interferes with assessments (vision, hearing impairment; phone screening)
  • history of neurological injury such as history of seizures, brain tumor, or stroke (phone screening) Parents/guardians of potential participants will be contacted via phone and/or email, at which time the details of the study will be specified and inclusion/exclusion criteria will be reviewed.
