The Function of Biphasic Sleep in Infants

Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. 9 months at the time of enrollment
  • 2. normal birthweight (5.5 to 10 lbs) and gestational length (36-41 weeks)
  • 3. must be willing and able to return for testing in 3 and 6 months (e.g., no plans to move out of the area)
  • 1. born premature (\<36 weeks gestational age)
  • 2. receiving services due to developmental delays
  • 3. visual or motor disability
  • 4. 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.
  • 5. 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).
  • 6. traveling beyond 1 time zone within 2 weeks prior to testing (phone screening)
  • 7. fever or symptoms of respiratory illness at the time of testing (phone screening)
  • 8. physical handicap that interferes with assessments (vision, hearing impairment; phone screening)
  • 9. 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.
