The purpose of the present study is to demonstrate reinforcement control over infant vocalization rates using a DRO schedule to control for elicitation of social stimulation. Mothers of four 2 1/2- to 3-month-old infants provided social reinforcement for their infants' vocalization under two schedules: continuous reinforcement (CRF) and differential reinforcement of other-than-vocalization (DRO). In a repeated-reversal single-subject experimental design, all four infants produced systematically higher vocalization rates during CRF, even though densities of social stimulation during DRO were equal to or greater than densities provided during CRF. Thus, whatever its elicitation value, social stimulation may reinforce infant vocalization rates.
本研究的目的是通过使用区别性强化其他行为（DRO）程序来控制社会刺激的引发，从而证明对婴儿发声频率的强化控制。四名2个半月至3个月大婴儿的母亲在两种程序下为婴儿的发声提供社会强化：连续强化（CRF）和区别性强化其他行为（DRO）。在重复反转单受试者实验设计中，尽管在DRO期间社会刺激的密度等于或大于CRF期间提供的密度，但所有四名婴儿在CRF期间的发声频率都系统地更高。因此，无论其引发价值如何，社会刺激可能会强化婴儿的发声频率。
