Abstract
-
The current study is an exploration of the parameters of delayed reinforcement with six 2- to 6-month-old infants in two experiments with single-subject repeated-reversal designs. In Experiment 1, unsignaled, 3-s delayed reinforcement was used to increase infant vocalization rate when compared to a differential-reinforcement-of-other-than-vocalization (DRO) condition and a yoked noncontingent comparison condition. In Experiment 2, unsignaled 5-s delayed reinforcement was used to increase infant vocalization rate when compared to an alternating-treatment comparison condition. The alternating-treatment comparison condition consisted of 3-min components of DRO and 3-min components of a nontreatment baseline. Successful conditioning was obtained in both Experiments of the current study. These results are in contrast to those of previous infant researchers who did not obtain conditioning with delays as long as 3 s with infants and who attributed their findings to the limitations of the infant's memory capacity. We present an alternative conceptual framework and methodology for the analysis of delayed reinforcement in infants.
