Developmental Changes in Infants' Response to Complex Facelike Patterns.
Haaf, Robert A.; Brown, Cheryl J.
Four experiments were conducted to investigate the extent to which infants of different ages respond to facelike drawings on the basis of stimulus complexity and/or resemblance to the human face. Infants' responses to stimulus patterns were assessed using the corneal reflection technique developed by Robert Trantz. In the first two experiments, 5-, 10-, 15-, and 20-week-old infants were shown four stimulus patterns differing in degree of resemblance to the face and degree of stimulus complexity. In the other two experiments, 10- and 15-week-old infants were shown six stimuli which represented three levels of complexity and two types of organization. The three stimulus patterns with nonfacial organization differed only in stimulus complexity. Those in the set with facial organization differed from each other in degree of facial resemblance as well as in complexity. The results of these four experiments indicated that there is a change between the ages of 10 and 15 weeks in the dimensions which underlie infants' response to facelike patterns. Older infants, 15 and 20 weeks, responded to both the degree of facial resemblance and the degree of complexity while younger infants, 5 and 10 weeks, responded only the complexity of facelike patterns.
