Brief Summary

Background: People show changes in brain activity when they watch other people do actions. This may be part of early social and communication skills. Researchers want to understand the stages of normal development of motor observation and imitation in people and how it relates to social development in infants and toddlers. Objective: To study the nature of brain activity that underlies typical brain functioning in infants, toddlers, and adults. Eligibility: Infants ages 8 12 months Healthy adults ages 18 65 Design: Adult participants will have one visit. They will: Answer questions about their family, like its size and ethnicity. Answer questions about their own behavior and do a simple motor task. Have EEG/fNIRS. A damp elastic cap with small sensors will be placed on the head. Participants will observe stimuli, either on a video screen or of a live person. The sensors will be connected to a computer. That will record the participant s brain activity while watching pictures on a screen. Infant participants will have 2 visits. Their parents will answer questions about their family. The parents will fill out forms about their child s development. These will be mailed to them before each visit. Parents will stay with their infant while study staff does an assessment of the child s communication, motor, and thinking skills. Infants will have EEG/fNIRS. Infants who are at risk for developmental delays will come back for another visit when they are about 2 years old. This will repeat the infant visits but it will not include EEG/fNIRS. Some questionnaires and assessments will be videotaped.

Outcome Measures

Primary Outcomes (2)

  • Developmental level

    Diagnostic status and behavioral scales that reflect child development at different levels: gross motor, fine motor, language and visual reception.

    Visit 2 for AR group

  • Hemodynamic response function and mu suppression

    The change in neuroimaging metrics (i.e., percent mu suppression, percent oxyhemoglobin change) will be used to characterize the development of the mirror neuron system.

    Visit 1 for Adult Pilot, TD and AR infants; visit 2 for TD infants

Study Arms (3)

Adult pilots

Healthy adults between the ages of 18-65 years

AR infants

Infants with 12 months of age (+/- 2 weeks) with one of the following: observed developmental delay, sibling of a child with autism, premature birth, small for gestational age.

TD infants

Healthy infants with 9 months of age (+/- 2 weeks)

Sampling MethodNon-Probability Sample
Study Population

Adult pilots and TD infants will be recruited from a community sample. AR infants will be recruited from local early intervention providers and pediatricians, following procedures of ongoing collaborative studies at NIH.

You may not qualify if:

  • Healthy Adults
  • Uncorrected auditory impairment
  • Uncorrected visual impairment
  • Head injury with loss of consciousness
  • Inability to provide consent
  • Subject has a condition, that in the opinion of the investigator, creates an unacceptable risk for participation
  • Healthy and At-Risk Infants
  • A language other than English as the primary language spoken at home
  • Having a medical impairment that interferes with study participation such as having a g-tube, shunt or seizure disorder and inability to hold one s head upright
  • Having a known visual impairment
  • Having a known auditory impairment
