Abstract

Stimulus over-selectivity describes a phenomenon in which an individual responds only to a subset of the stimuli present in the environment and, thus, may restrict learning. This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of over-selectivity to core deficits of ASD: stereotyped responding and inflexibility. Over-selectivity was investigated in a visual discrimination task in 24 children, 12 diagnosed with ASD and 12 mental-age-matched typically developing children. In addition, the participants’ levels of intellectual functioning, stereotypy, and cognitive flexibility were assessed using established tools. Results showed that over-selectivity was associated with IQ and stereotyped behavior but was not related to levels of cognitive flexibility nor did cognitive flexibility significantly correlate with stereotyped behavior in individuals with ASD. The current findings require consideration when designing behavioral interventions for individuals with ASD.

自闭症谱系障碍儿童刺激过度选择性的研究及其与刻板印象行为和认知灵活性的关系

刺激过度选择性描述了一种现象，在这种现象中，个体只对环境中存在的一小部分刺激做出反应，因此可能会限制学习。本研究旨在通过分析过度选择性与自闭症谱系障碍(ASD)核心缺陷:刻板反应和缺乏灵活性的关系，进一步了解过度选择性在自闭症谱系障碍(ASD)中的本质和作用。对24名儿童，12名诊断为ASD的儿童和12名智力年龄匹配的正常发育儿童进行了视觉辨别任务的过度选择性研究。此外，参与者的智力功能水平、刻板印象和认知灵活性使用既定的工具进行评估。结果表明，过度选择性与智商和刻板行为有关，但与认知灵活性水平无关，认知灵活性与ASD个体的刻板行为也没有显著相关性。目前的研究结果需要在为自闭症患者设计行为干预措施时加以考虑。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
