The influence of perinatal risk status on contingency learning in six- to thirteen-month-old infants.
Learning of a manipulative response was examined in 6-13-month-old well babies and in risk infants who, in the perinatal period, had experienced a range of respiratory interventions (low- and high-risk). 2 contingency conditions (contingent and yoked) were crossed with 2 locations of feedback (local and remote). Both well-baby and low-risk groups reliably discriminated between contingent and noncontingent feedback when it was presented locally, whereas high-risk babies failed to make this distinction in the conditioning phase. Risk status reliably predicted the learning performance. No response acquisition was obtained in the remote feedback condition. In extinction, the well-baby and low-risk groups decreased their responding, but the high-risk group showed an initial response burst. The findings are discussed in the context of risk-related differences in contingency awareness and frustrative nonreward. Overall, the results confirm that the effects of perinatal compromise involving respiratory complications influence infants' processing of contingency information during the first year of life.
