Attachment status and complexity of infants' self- and other-knowledge when tested with mother and father

At 13 and 20 months, infants' featural knowledge of self and parent was assessed separately with mother and father. Infants' featural knowledge was measured by a scale that included tasks reflecting infants' knowledge of facial features, spatial location, name, possession and gender. No significant relation between attachment status and featural knowledge was obtained at 13 months when tested with either parent. At 20 months, in contrast, more complex featural knowledge of self and parent was demonstrated by infants who were securely attached than by those who were insecurely attached. Independent of age, however, infants' featural knowledge of their mothers was more complex than that of their fathers, although no differences in self-knowledge were obtained as a function of parent gender. These data are understood in the context of cognitive development and the differences in interactional qualities assessed by attachment status and parent gender.
