• 1 other identifier: HS-FY2023-23 Study 2
• Study Type: observational
• Target: 100
• Locations: 1 country
• Sites: 1

Brief Summary

Researchers at the Diversity in Development Lab at UC Santa Cruz are investigating how babies' brain activities respond to people from familiar and unfamiliar racial backgrounds.

Conditions

Infant Development

Outcome Measures

Primary Outcomes (3)

• Mu event related desynchronization

  EEG oscillation in alpha power over central regions

  Through study completion, an average of 10 years.

• Frontal theta synchronization

  EEG oscillation in theta power over frontal regions

  Through study completion, an average of 10 years.

• Frontal alpha asymmetry

  left and right hemispheric difference in EEG oscillation in alpha power in the frontal regions

  Through study completion, an average of 10 years.

Interventions

Infants observing familiar and unfamiliar racial groups OTHER

All infants will see videos of people from familiar and unfamiliar racial backgrounds. Depending on the caregiver's race, infants will be assigned to see people who are from the same racial background as their caregiver (i.e., familiar) and people who are not.

Eligibility Criteria
