Abstract
Looking and reaching preferences for different-sized objects were examined in 4–5- and 5–6-month-old infants. Infants were presented with pairs of different sized cylinders and preferences were analyzed by age and reaching status. Outcome variables included looking and touching time for each object, first look, and first touch. Significant three-way interactions with age and reaching status were found for both infants’ looking and touching duration. Four–5- and 5–6-month-olds with less reaching experience spent more time visually and manually exploring larger objects. In contrast, 5–6-month-olds with more reaching experience spent more time looking at and touching smaller objects, despite a first look and first touch preference for the largest object. Initially, looking and reaching preferences seem to be driven by mechanisms responding to general visual salience independent of an object’s potential for manual action. Once reaching skills emerge, infants begin to use visual information to selectively choose smaller, more graspable objects as exploration targets.
