Research has shown that variability may be an operant dimension of behavior. One method of reinforcing response variability is to use a lag schedule of reinforcement (Page & Neuringer, 1985). Several studies have shown that a Lag 1 schedule is effective in increasing variable responding with human participants (e.g., Esch, Esch, & Love, 2009; Lee, McComas, & Jawor, 2002). In these arrangements, however, the return to baseline responding during reversal phases suggests that the resulting behavior change may not be maintained following intervention. The purpose of the present study was to investigate the effects of a Lag 3 schedule on increasing and maintaining variability of tacts in 2 children diagnosed with developmental disabilities. Results demonstrated increased variability in tacting for both participants and maintenance in variable responding after a 3-week follow-up.
研究表明，变异性可能是行为的一个操作性维度。强化反应变异性的一种方法是使用滞后强化程序（佩奇和诺伊林格，1985年）。多项研究表明，滞后1程序在增加人类参与者的可变反应方面是有效的（例如，埃施、埃施和洛夫，2009年；李、麦科马斯和贾沃尔，2002年）。然而，在这些安排中，反转阶段回到基线反应表明，干预后产生的行为变化可能无法维持。本研究的目的是调查滞后3程序对增加和维持两名被诊断为发育障碍儿童的触觉变异性的影响。结果表明，两名参与者的触觉变异性均有所增加，且在3周的随访后可变反应得以维持。
