Abstract:
Adults attach special value to objects that link to notable people or events - authentic objects. We examined children's monetary evaluation of authentic objects, focusing on four kinds: celebrity possessions (e.g., Harry Potter's glasses), original creations (e.g., the very first teddy bear), personal possessions (e.g., your grandfather's baseball glove), and merely old items (e.g., an old chair). Children ages 4-12 years and adults (N= 151) were asked how much people would pay for authentic and control objects. Young children consistently placed greater monetary value on celebrity possessions than original creations, even when adults judged the two kinds of items to be equivalent. These results suggest that contact with a special individual may be the foundation for the value placed on authentic objects.
