Stimulus overselectivity is widely accepted as a stimulus control abnormality in autism spectrum disorders and subsets of other populations. Previous research has demonstrated a link between both chronological and mental age and overselectivity in typical development. However, the age at which children are developmentally ready to respond to discriminations involving simultaneous multiple cues has not been established. Thirty-seven typically developing preschoolers completed a task requiring response to simultaneous cues (color and shape) to establish the age at which typically developing children can successfully respond to multiple cues. Results demonstrate that typically developing children under 36 months of age have difficulty responding to multiple cues. Implications for behavioral treatment for autism are discussed.
刺激过度选择被广泛认为是自闭症谱系障碍和其他人群亚组中的一种刺激控制异常。先前的研究表明，在典型发育中，年龄（包括实际年龄和心理年龄）与过度选择之间存在关联。然而，儿童在发展上准备好应对同时涉及多个线索的辨别任务的年龄尚未确定。37 名典型的学龄前儿童完成了一项需要对同时出现的线索（颜色和形状）做出反应的任务，以确定典型发育的儿童能够成功应对多个线索的年龄。结果表明，年龄小于 36 个月的典型发育儿童难以对多个线索做出反应。讨论了这对自闭症行为治疗的意义。
