Five autistic and five normal children were allowed to register a sensory modality preference by bar pressing to select either a visual (slides) or an auditory (music) stimulus. The children were then taught a discrimination between the presence or absence of a compound auditory-visual stimulus (white noise and light). Testing for stimulus overselectivity revealed that the autistic children attended to only one aspect of the compound stimulus. In all cases this was the sensory modality that was selected during the preference test. Significant correlations were obtained between Gesell developmental scores and degree of overselectivity. Normal children registered an equal preference for music and slides and displayed no overselectivity.
让五名自闭症儿童和五名正常儿童通过按压杠杆来选择视觉刺激（幻灯片）或听觉刺激（音乐），以此来记录他们对一种感觉模态的偏好。然后教导这些儿童区分复合视听刺激（白噪音和光）的有无。对刺激过度选择性的测试表明，自闭症儿童只关注复合刺激的一个方面。在所有情况下，这都是在偏好测试中选择的感觉模态。盖塞尔发育分数与过度选择性程度之间存在显著相关性。正常儿童对音乐和幻灯片表现出同等偏好，且没有表现出过度选择性。
