自闭症谱系障碍（ASD）的特征在于处理与被试的上下文信息有关的感知刺激的能力有限。这种非整体性处理方式和与ASD相关的行为特征之间的联系被认为也存在于神经典型人群中，尽管方式更微妙。我们通过测试语音分类是否在多大程度上改变了语音感知，使其成为已知单词（即，“Ganong效应”）在神经型患者中作为自闭症特征的函数而减弱。55名大学生被给予自闭症谱系商数（AQ）和使用两个单词到非单词的语音起始时间（VOT）连续（kiss-giss和gift-kift）的片段识别测试。一个显着的负相关性被发现之间的总AQ评分和识别之间发生的连续性的转变。AQ分数与单独管理的VOT歧视，听觉词汇决策，或言语智商的分数没有相关性，从而排除了增强听觉灵敏度，较慢的词汇访问或言语智力作为解释的AQ相关的语音分类的转变。
It has been claimed that Autism Spectrum Disorder (ASD) is characterized by a limited ability to process perceptual stimuli in reference to the contextual information of the percept. Such a connection between a nonholistic processing style and behavioral traits associated with ASD is thought to exist also within the neurotypical population albeit in a more subtle way. We examined this hypothesis with respect to auditory speech perception, by testing whether the extent to which phonetic categorization shifts to make the percept a known word (i.e., the ‘Ganong effect’) is weakened as a function of autistic traits in neurotypicals. Fifty-five university students were given the Autism-Spectrum Quotient (AQ) and a segment identification test using two word-to-nonword Voice Onset Time (VOT) continua (kiss-giss and gift-kift). A significant negative correlation was found between the total AQ score and the identification shift that occurred between the continua. The AQ score did not correlate with scores on separately administered VOT discrimination, auditory lexical decision, or verbal IQ, thus ruling out enhanced auditory sensitivity, slower lexical access or verbal intelligence as explanations of the AQ-related shift in phonetic categorization.
