When an individual has limited language, concurrent‐chains schedules offer an objective means of assessing preference among behavior‐change procedures so that recipients can be incorporated into the treatment selection process. We initially attempted to use a concurrent‐chains schedule to assess children's preference for different types of token systems. However, upon observing children engaging in patterned selections, we evaluated procedures for eliminating biased selections. This was done using simple and salient terminal‐link arrangements with seven children diagnosed with autism spectrum disorder. For five of seven children, manipulating the number of successive forced‐choice trials to the reinforcement link was sufficient to produce discriminated responding. Removing the academic task in the terminal link was necessary for two children. For all participants, discriminated responding maintained when the initial exposure arrangement was reinstated. Results are discussed regarding the potential effects of a history of errorless teaching biasing selections during concurrent‐chains schedules.

消除并发链调度期间的偏见选择：一个发现研究示例

当一个人的语言能力有限时，并发链时间表提供了一种评估行为改变程序偏好的客观方法，以便接受者可以纳入治疗选择过程。我们最初尝试使用并发链计划来评估儿童对不同类型代币系统的偏好。然而，在观察儿童参与模式选择后，我们评估了消除偏见选择的程序。这是通过对七名被诊断患有自闭症谱系障碍的儿童使用简单而显着的终端链接安排来完成的。对于七个孩子中的五个来说，操纵强化链接的连续强制选择试验的数量足以产生有区别的反应。对于两个孩子来说，取消终端环节的学业任务是必要的。对于所有参与者来说，当恢复最初的暴露安排时，歧视性的反应仍然存在。讨论了关于并发链计划期间无错误教学偏差选择历史的潜在影响的结果。
