Snakes and spiders are two of the most commonly feared animals worldwide, yet we know very little about the mechanisms by which such fears are acquired. We explored whether negative information about snakes and spiders from parents shapes children's fear beliefs. Study 1 included 27 parents (22 mothers, five fathers) and children (12 female, 15 male, Mage = 5.33 years, 18 White, one Hispanic, eight more than one race). Most parents reported having an advanced degree (78%) and an annual household income of above $100,000 (74%). Participants read an animal picture book and then rated their fear toward each animal. Study 2 included 54 parents (44 mothers, eight fathers, two legal guardians) and children (27 female, 27 male, M[subscript age] = 5.52 years, 30 White, one Hispanic, seven Asian/Pacific Islander, four South Asian/Indian, 12 more than one race). Most parents reported holding an AA/BA degree (28%) or an advanced degree (59%) and reported an annual household income of $60,000--$100,000 (28%) or above $100,000 (59%). In Study 2, half of the parents were primed about how their conversations might shape children's fear prior to reading the book. Across both studies, we found that participants provided more negative than positive information about snakes and spiders and provided less positive (Study 1) and more negative (Study 2) information compared to other animals. Our results highlight the prominence of negative information in conversations about snakes and spiders and suggest that the way parents talk about these animals may shape the development of children's fears.
