Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will assess if toddlers show differences in stranger wariness according to race, temperament, social network diversity, and neighborhood diversity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is investigating 13- to 24-month-old toddlers' reactions to meeting new people from familiar and unfamiliar racial backgrounds! Participation involves a 1-hour one-time visit to the researcher's lab, located on the UC Santa Cruz campus.

The study itself will take about 20 minutes, but will ask for a 1-hour visit to make sure child participants feel comfortable in the new space. The study will video record as child participants interact with two adults, who will play with the child and offer toys. Parent participants will also be asked to complete two surveys, one demographic survey and one social network survey, so that investigators can better understand how the people children see in their daily lives relate to how participants react to strangers from different racial backgrounds.
