Summary
Acquisition of a manipulative response under contingent and non-contingent maternal social stimulation was examined in seven- and ten-month-old infants. Response acquisition was reliably deomonstrated in the case of the ten-month-old infants, but not in the case of the seven-month-old infants. However, despite no acquisition, the performance of the younger infants did differ from that obtained under non-contingent scheduling Examination of visual behaviour to the manipulandum and the feedback source revealed comparable profiles for both ages. The findings are interpreted in terms of the greater difficulty of mixed social/non-social contingency situations and discussed in the context of cognitive constraints on response acquisition in infancy.
