This study examined the abilities of 10-month-old infants to detect correlations between objects and persons based on the characteristic of gender. A total of 32 infants were habituated to six stimuli in which a picture of a male or female face was paired with one of six objects such as a football or frying pan. Three objects were associated with female faces and three with male faces. Infants were then presented with test stimuli in four conditions: (1) control, which duplicated one of the habituation stimuli pairs; (2) generalized, which paired an object from the habituation stimuli pairs with a different face of the same gender; (3) novel, which paired an object from the habituation stimuli pairs with a face of the opposite gender; and (4) unique, which paired a new object with a face. Analysis of infants' looking times indicated that infants' looking times in the control and generalized conditions did not differ from each other and were less than their looking times in the novel test condition. Results suggest that 10-month-old infants are capable of forming categories based on their detection of correlations among features of gender. (SM)
