McCall, Robert B.; Kagan, Jerome – Develop Psychol, 1970
Results of this study of 72 4-month-old infants suggest caution in using an overt demonstration of habituation as a necessary index of perceptual learning. (Author/MG)

Four facial stimuli derived from the Bolton standards of craniofacial development representing a human male at 6 months, 3, 8, and 18 years of age were used in a test of Lorenz's concept of babyishness and of the discrepancy hypothesis. Subjects were 87 four-month-old infants. (Author/MP)

Studies of the infant's distribution of attention to stimuli of varying complexity, and of his differential attention to familiar versus novel stimuli (discrepancy), have attempted to shed light on the development of cognitive structures in the non-verbal infant. The subjects have typically been normal infants ages 4 to 6 months. For testing, the…

Individual differences in pattern of habituation in fixation time and cardiac change to visual and auditory stimuli are described. Subjects were 94 5- and 10-month-old infants. (Author/MP)

Peer reviewedMcCall, Robert B. – Merrill-Palmer Quarterly, 1990
Examines strategies for studying individual differences in infant behavior from the standpoints of the distinction between individual differences and developmental function and the need to study change with multivariate techniques. These themes are applied to the study of mental development, behavior genetics, temperament, and attachment. (RJC)

Peer reviewedMcCall, Robert B. – Monographs of the Society for Research in Child Development, 1974
Reports a series of studies conducted to investigate possible differences in the exploratory manipulation and play behavior of human infants 7-1/2- 11-1/2 months of age as a function of the attributes of the stimulus, the familiarity of the subject with the stimuli, the age and sex of the infants, and individual differences.

McCall, Robert B. – 1972
Function of attention in infants is explored. Assuming (1) that infants respond differently to novel situations than to familiar ones; (2) that the infant's pattern of response is a partial reflection of the process of acquiring a perceptual memory of the stimulus, and (3) that sex differences may occur in the rate of habituation, 120 infants…
