Increasing immigration and diversity in the United States has expanded children’s exposure to individuals of various cultural backgrounds who engage in new and unfamiliar cultural behaviors; this has the potential to lead to the development of biases for children’s own cultural group. One important culturally relevant behavior that people engage in is food choice. Previous studies have demonstrated that children recognize the sociality of food choice and use it to guide their understanding of group membership. The present studies asked children to evaluate who eats familiar foods, unfamiliar foods (Studies 1 & 2), and disgust elicitors (Study 2). We find that children evaluate familiar foods as being more likely to be eaten by those from a familiar country, unfamiliar foods by those from an unfamiliar country, and disgust elicitors would be eaten by neither. However, these studies did not answer whether children’s matching choices were related to their cultural familiarity with the foods or their personal preferences for them. Therefore, we examined which foods were most neutrally preferred but most familiar with children. We introduced children to 12 common American foods in which they rated their preference of those foods, and their parents filled out a questionnaire to measure the children’s familiarity. We found a subset of foods that are both familiar with children that are familiar with and are neutrally preferred. With this narrowed list of foods that are culturally unique to America from the pilot study, we can eliminate the factor of preference when conducting the actual study. We are interested in seeing if children’s biases are linked to expecting to see people from an unfamiliar country engaging in culturally unfamiliar behaviors, perhaps their biases can be reduced through seeing people from an unfamiliar country engage in culturally familiar behaviors.
