Rule-Transfer in the Infant Visual Expectation Paradigm.
McCarty, Michael E.; Haith, Marshall M.
This study investigated: (1) whether infants can develop expectations for events that alternate along the vertical axis; and (2) whether infants who form expectations with one action set can transfer them to a different action set--that is, from vertical to horizontal eye movements. A total of 32 infants of 3 months of age saw one of two picture sequences. Babies in the Rule-Rule group saw 30 pictures alternating in up and down locations followed by 30 pictures alternating in left and right locations. Random-Rule babies saw an identical sequence, except that the first 30 pictures appeared in an unpredictable up and down sequence. Findings revealed that Rule-Rule babies produced a higher percentage of anticipations for the up and down pictures and lower optimal-median response times than did Random-Rule babies. For the left and right pictures, there were no significant response time differences between the two groups. However, the correlation between response times for the up and down and left and right pictures was substantially higher for the Rule-Rule babies than for the Random-Rule babies. Evidence was found for transfer of expectations between different action sets. (RH)
