The participants were 18 2-year-old children (M = 31.1 months; 11 girls), 18 3-year-old children
(M = 41.6 months; 6 girls), 18 4-year-old children (M = 53.9 months; 11 girls), and 40 adults. All children

of an object across early childhood. Adult participants were undergraduate students recruited from
the department’s subject pool. Adult participants received course credit for their participation. Participants
