Previous research has suggested that the response‐independent delivery of preferred stimuli can increase compliance to low‐probability instructions, although these results have been mixed. Two variables that might affect compliance during this procedure are the magnitude and duration of access to the stimuli. In the current study, we evaluated stimulus magnitude and duration of access during pretrial delivery of preferred items on compliance among children with autism. In Experiment 1, we compared high and low magnitude edible stimuli. In Experiment 2, we compared long and short durations of access to leisure stimuli. Results show that high magnitudes and long durations of access to preferred stimuli delivered once immediately before a low‐probability instruction increased compliance more than low magnitudes and short durations of access to preferred stimuli. We discuss the implications and possible mechanisms responsible for these results.

在预交付首选项目期间刺激幅度和持续时间对增加依从性的影响

先前的研究表明，首选刺激的响应独立传递可以增加对低概率指令的依从性，尽管这些结果好坏参半。在此过程中可能影响依从性的两个变量是获得刺激的幅度和持续时间。在目前的研究中，我们评估了在审前交付有关自闭症儿童依从性的首选项目期间的刺激强度和访问持续时间。在实验 1 中，我们比较了高强度和低强度的食用刺激。在实验 2 中，我们比较了获得休闲刺激的长短持续时间。结果表明，在低概率指令之前立即提供一次高强度和长持续时间的首选刺激，比低强度和短时间的首选刺激更能增加依从性。我们讨论了导致这些结果的含义和可能的机制。
