A case study was reported in which a 9-year-old male autistic boy was initially trained to discriminate between two auditory stimuli and two visual stimuli. He was then tested for overselective responding to bidimensional combinations of the four stimuli. It was hypothesized that the overselectivity results reported in previous studies were partially a function of a procedure in which autistic children were reinforced for responding in the presence of a multidimensional stimulus complex and then tested with individual stimuli. The child in the present investigation, with the alternative procedure, did not demonstrate overselective responding. Two interpretations of the results were presented, neither of which was consistent with an overselectivity theory. Future research should delineate the specific conditions which produce overselective responding, and suggest methods to facilitate more adaptive responding of autistic children.
报告了一项案例研究，其中一名9岁的自闭症男孩最初接受训练，以区分两种听觉刺激和两种视觉刺激。然后对他进行测试，以观察其对这四种刺激的二维组合的过度选择性反应。据推测，先前研究中报告的过度选择性结果部分是由于一种程序导致的，在该程序中，自闭症儿童在多维刺激复合体出现时做出反应会得到强化，然后再用单个刺激进行测试。本研究中的儿童采用了另一种程序，并未表现出过度选择性反应。文中提出了对结果的两种解释，但均与过度选择性理论不一致。未来的研究应明确产生过度选择性反应的具体条件，并提出促进自闭症儿童更适应性反应的方法。
