This study was undertaken to examine whether children exhibit the same relationship that adults show between lexical influence on phoneme identification and individual variation on the Autism-Spectrum Quotient (AQ).
Data from 62 4- to 7-year-olds with no diagnosis of autism were analyzed. The main task involved identification of the initial sound in pairs of voice-onset time continua with a real word on one end and a nonword on the other (e.g., gift-kift, giss-kiss). Participants were also given the children's version of the AQ and a 2nd instrument related to autistic-like traits, the Social Responsiveness Scale (SRS).
The lexical shift was related to the AQ (particularly to its Attention Switching subscale) but not to the SRS.
The size of lexical effects on children's speech perception can be predicted by AQ scores but not necessarily by other measures of autism-like traits. The results indicate that speech perception in children manifests individual differences along some general dimension of cognitive style reflected in the AQ, possibly in relation to local/global information processing.
本研究旨在探究儿童在词汇对音素识别的影响与自闭症谱系商数（AQ）个体差异之间是否呈现出与成人相同的关系。
对62名未被诊断为自闭症的4至7岁儿童的数据进行分析。主要任务是识别语音起始时间连续体对中的初始音，一端是实词，另一端是无意义词（例如，gift - kift，giss - kiss）。参与者还接受了儿童版的AQ以及与自闭症样特征相关的第二种工具——社会反应量表（SRS）。
词汇转移与AQ相关（特别是与注意力转换子量表相关），但与SRS无关。
词汇对儿童言语感知的影响大小可以通过AQ分数预测，但不一定能通过其他自闭症样特征的测量方法预测。结果表明，儿童的言语感知在AQ所反映的认知风格的某些一般维度上表现出个体差异，这可能与局部/全局信息处理有关。
