Study Background
How do early life experiences influence young children’s responses to strangers?
In this study, we are investigating toddlers’ reactions to meeting new people from familiar and unfamiliar racial backgrounds! Participation involves a 1-hour one-time visit to our lab, located on the UC Santa Cruz campus (in Social Science 2 building (Social Sciences 2, 712 College Ten Rd, Santa Cruz, CA 95064). Free parking is included and siblings are welcome! All families will receive up to $30 for their participation.
The study itself will take about 20 minutes, but we will ask for a 1-hour visit to make sure your child feels comfortable in the new space. We will video record as your child interacts with two adults, who will play with your child and offer toys. You as the parent will also be asked to complete two surveys, one demographic survey and one social network survey, so that we can better understand how the people your child sees in their daily lives relate to how they react to strangers from different racial backgrounds.
If you have a toddler aged 16-36 months, your child may be eligible to participate in this study. Help advance research by joining today!

Study Background
Understanding how young children start to interact across racial lines.
This study explores how toddlers respond when meeting new people, particularly from both familiar and unfamiliar racial backgrounds. The goal is to better understand how a child’s everyday experiences influence their early ideas about race and social behavior.
Early childhood is a key time when foundational social attitudes begin to form. By observing how toddlers interact with unfamiliar adults of different racial backgrounds, researchers hope to learn more about how young children process social and racial cues. This work will provide insight into how early experiences with diversity shape a child’s developing worldview and may help inform future parenting and educational strategies.
