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.
先前的研究表明，对偏好刺激的无反应性传递可以提高对低概率指令的依从性，尽管这些结果参差不齐。在这个过程中可能影响依从性的两个变量是对刺激的获取的大小和持续时间。在当前的研究中，我们评估了在自闭症儿童的服从性测试中，在偏好项目的预试验传递期间，刺激的大小和持续时间。在实验 1 中，我们比较了高和低大小的可食用刺激物。在实验 2 中，我们比较了对休闲刺激物的长和短的获取持续时间。结果表明，在低概率指令之前立即传递一次的高大小和长时间的偏好刺激的获取比低大小和短时间的偏好刺激的获取更能增加依从性。我们讨论了这些结果的意义和可能的机制。
