事件相关脑电位（ERP）引起的视觉和听觉刺激，记录了非弱智个体孤独症（年龄13-25岁）和年龄匹配的正常对照。在“无任务”条件下，受试者只是看或听这些刺激;只有1个差异，发现受试者组之间。几个ERP组之间的差异被发现在“任务”条件下，受试者按下一个按钮，在发生的目标刺激混杂着意想不到的，新颖的刺激，也与预期的，非新颖的刺激。自闭症组的视觉ERP异常不同于听觉异常。非智力迟钝的孤独症患者处理新信息的能力可能有限。他们既不对新信息过敏，也不把它误认为是非新的和无关紧要的。简单视觉信息的分类可能比听觉信息的分类受损更小。除了一个例外，视觉和听觉ERP异常似乎并不反映成熟延迟。
Event-related brain potentials (ERP) elicited by visual and auditory stimuli were recorded from nonretarded individuals with autism (ages 13-25 yr) and age-matched normal controls. In "no-task" conditions, subjects simply looked at or listened to these stimuli; only 1 difference was found between subject groups. Several ERP differences between groups were found in "task" conditions; subjects pressed a button at the occurrence of target stimuli intermixed with unexpected, novel stimuli and also with expected, nonnovel stimuli. Visual ERP abnormalities in the autistic group differed from auditory abnormalities. Nonretarded autistic individuals may have a limited capacity to process novel information.sbd.they are neither hypersensitive to novel information nor misperceive it as nonnovel and insignificant. Classification of simple visual information may be less impaired than auditory. With 1 exception, visual and auditory ERP abnormalities do not seem to reflect maturational delay.
