Previous research suggests that model competence does not emerge until relatively late in infancy (20-26 months). Development was systematically analyzed within 3 key areas--count noun learning, dual representation, and categorization--hypothesized to support the emergence of model competence in the second year. In an object-handling preferential…

This study was designed to test two alternate hypotheses regarding the meaning of increased lateral head movements in infants during experiments in which the mothers' voices were displaced from their faces. One interpretation is that the lateral looking responses of the infants are attributable to maturational effects on the infants' physiological…

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)

Infants 8.5 and 9.5 months of age were tested for ability to determine the location of an object hidden in one of two covered containers before their left-right positions were reversed. Only the older infants provided with different colored covers to their containers were able to do this task. (Author/DB)
