Toddlers' Responses to Strangers
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.

Babies' Brain Responses to Strangers
The goal of this observational study is to learn how infants' brain activities, as captured by EEG, differ for familiar or unfamiliar racial group in typically developing infants. The main questions of the study are: - Will infants show greater event-related desynchronization (i.e., more motor system activation), frontal theta synchronization (i.e., more attention), and more positive frontal alpha asymmetry (i.e., more approach motivation) to familiar than unfamiliar racial group? - How does infants' exposure to racial diversity in their social network and neighborhoods relate to these EEG activities? Participants will visit a laboratory at the UC Santa Cruz campus for this study. Infants will put an EEG cap on and watch about 15 minutes of videos, in which people from different racial backgrounds do different actions (e.g., grabbing an object, saying hi and approaching closer, and playing peek-a-boo). Caregivers will be asked to fill out a demographic form and a social network survey.
