  • Title: Event-related potential (ERP) indices of infants' recognition of familiar and unfamiliar objects in two and three dimensions.
    Author: Carver LJ, Meltzoff AN, Dawson G.
    Journal: Dev Sci; 2006 Jan; 9(1):51-62. PubMed ID: 16445396.
    Abstract:
    We measured infants' recognition of familiar and unfamiliar 3-D objects and their 2-D representations using event-related potentials (ERPs). Infants differentiated familiar from unfamiliar objects when viewing them in both two and three dimensions. However, differentiation between the familiar and novel objects occurred more quickly when infants viewed the object in 3-D than when they viewed 2-D representations. The results are discussed with respect to infants' recognition abilities and their understanding of real objects and representations. This is the first study using 3-D objects in conjunction with ERPs in infants, and it introduces an interesting new methodology for assessing infants' electrophysiological responses to real objects.
