COMPONENTS OF VISUAL ORIENTING IN EARLY INFANCY - CONTINGENCY LEARNING, ANTICIPATORY LOOKING, AND DISENGAGING

Three aspects of the development of visual orienting in infants of 2, 3, and 4 months of age are examined in this paper. These are the age of onset and sequence of development of (1) the ability to readily disengage gaze from a stimulus, (2) the ability to consistently show "anticipatory" eye movements, and (3) the ability to use a central cue to predict the spatial location of a target. Results indicated that only the 4-month-old group was easily able to disengage from an attractive central stimulus to orient toward a simultaneously presented target. The 4-month-old group also showed more than double the percentage of "anticipatory" looks than did the other age groups. Finally, only the 4-month-old group showed significant evidence of being able to acquire the contingent relationship between a central cue and the spatial location (to the right or to the left) of a target. Measures of anticipatory looking and contingency learning were not correlated. These findings are, in general terms, consistent with the predictions of maturational accounts of the development of visual orienting.
