We replicated and extended previous research on microswitch facilitated choice making by individuals with profound multiple disabilities. Following an assessment of stimulus preferences, we taught 6 adults with profound multiple disabilities to emit 2 different responses to activate highly preferred stimuli. All participants learnt to activate both microswitches. Five participants showed a higher overall level of responding when both switches activating preferred stimuli were available concurrently. After completion of microswitch training, a choice assessment was conducted in which participants had access to 2 microswitches concurrently, with 1 connected to the most highly preferred stimulus and the other to a least preferred stimulus. Choice making behavior was shown in 3 participants and provided support for the preference assessment results. The results of the 3 remaining participants showed that both the most highly preferred and the least preferred stimuli may serve as reinforcers for microswitch activation responses.
我们复制并扩展了先前关于深度多重残疾个体通过微开关促进选择的研究。在对刺激偏好进行评估后，我们教导 6 名深度多重残疾成年人发出 2 种不同的反应来激活高度偏好的刺激。所有参与者都学会了激活两个微开关。当同时激活两个偏好刺激的微开关可用时，5 名参与者表现出更高的整体反应水平。微开关训练完成后，进行了一项选择评估，参与者可以同时使用 2 个微开关，其中 1 个连接到最受喜爱的刺激，另一个连接到最不受欢迎的刺激。在 3 名参与者中观察到了选择行为，这为偏好评估结果提供了支持。其余 3 名参与者的结果表明，最受喜爱的刺激和最不受欢迎的刺激都可以作为微开关激活反应的强化物。
