Learning and Memory Facilitate Predictive Tracking in 4-Month-Olds
Johnson, Scott P.; Shuwairi, Sarah M.

We investigated 4-month-olds' oculomotor anticipations when viewing occlusion stimuli consisting of a small target that moved back and forth repetitively while the center of its trajectory was occluded by a rectangular screen. We examined performance under five conditions. In the "baseline" condition, infants produced few predictive relative to reactive eye movements. In the "full training" condition, anticipations were increased in frequency following prior exposure to a target moving along a fully visible trajectory. The "delay" condition tested the effects of training after a 30-min interval elapsed between training and test, resulting in a return to baseline performance. However, the training effect was reinstated in the "reminder" condition following another brief exposure to the training stimulus prior to test. Finally, in the "brief training" condition, we found that the brief exposure alone was insufficient to induce the training effect. Results are interpreted in the context of learning from short-term experience and long-term memory. (Contains 1 table and 2 figures.)
