Functional communication training (FCT) is used to reduce rates of problem behavior by teaching communicative responses that access functionally equivalent reinforcers. During FCT, the communicative response is typically placed on a dense schedule of reinforcement that is unlikely to be maintained in the natural environment. Experiment 1 evaluated the effects of two schedule-thinning procedures (chained schedules and multiple schedules) on problem behavior maintained by escape from demands for three participants following FCT. The chained and multiple-schedule procedures were effective in reducing rates of problem behavior. Compliance increased under both schedules, but the chained schedule resulted in higher levels of compliance with two participants. In Experiment 2, participants’ preference for the chained or multiple-schedule procedure was evaluated using a modified concurrent-chain procedure. One participant preferred the chained schedule. One participant preferred the multiple schedule. One participant did not appear to discriminate between conditions.

功能性交流训练 (FCT) 用于通过教授访问功能等效强化物的交流反应来降低问题行为的发生率。在 FCT 期间，交际反应通常被放置在密集的强化计划中，这种强化计划不太可能在自然环境中维持。实验 1 评估了两个日程细化程序（链式日程和多日程）对 FCT 后三名参与者逃避需求所维持的问题行为的影响。链式和多计划程序可有效降低问题行为的发生率。两个时间表的合规性都有所提高，但链式时间表导致两个参与者的合规性更高。在实验 2 中，参与者对链式或多计划程序的偏好使用修改后的并发链程序进行评估。一位参与者更喜欢链式时间表。一位参与者更喜欢多个时间表。一名参与者似乎没有区分条件。
