Toddlers' Responses to Strangers Study

This study is looking at how toddlers react to meeting new people from different racial backgrounds. Researchers want to see if a child's reaction to strangers is influenced by their race, personality (temperament), the variety of people they see in their daily lives, and the diversity of their neighborhood. Your child, if they are between 13 and 24 months old and developing typically, could participate. The study will observe your child's "stranger wariness" (how cautious they are around new people) and "social preference" (who they seem to prefer interacting with) over an average of 10 years. The study is currently recruiting up to 100 children.

Study design
This is an observational study, meaning researchers will watch and record children's reactions without giving any treatments. It plans to include up to 100 participants.
What's involved
Participation involves one 1-hour visit to the lab on the UC Santa Cruz campus. During this visit, your child will interact with two adults for about 20 minutes, and you will complete two surveys.
Compensation
Not stated in the trial record.
Follow-up
Researchers will measure social wariness and social preference through study completion, an average of 10 years.

age 13-24 months
  • Social WarinessThrough study completion, an average of 10 years

    children's social wariness as assessed by the time that the child first vocalized, touched the stranger, and the duration of time that the child stayed near their parent in seconds standardized and averaged to create a composite score.

  • Social PreferenceThrough study completion, an average of 10 years

    Social preference will be coded by observing toddler behavior and assigning the following codes: 1 = did not take the toy from either stranger, 2 = took toy from familiar race stranger, 3 = took toy from unfamiliar race stranger, 4 = took toy or played with both strangers simultaneously.
