We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception of first order static stimuli, diminished perception of complex movement, autonomy of low-level information processing toward higher-order operations, and differential relation between perception and general intelligence. Increased perceptual expertise may be implicated in the choice of special ability in savant autistics, and in the variability of apparent presentations within PDD (autism with and without typical speech, Asperger syndrome) in non-savant autistics. The overfunctioning of brain regions typically involved in primary perceptual functions may explain the autistic perceptual endophenotype.
我们提出了一个“增强感知功能”模型，该模型涵盖了自闭症和非自闭症个体在社交和非社交感知处理方面的主要差异：局部定向的视觉和听觉感知、增强的低级辨别能力、在“复杂”视觉任务中使用更靠后的神经网络、增强的一阶静态刺激感知、对复杂运动感知的减弱、低级信息处理相对于高级操作的自主性，以及感知与一般智力之间的差异关系。感知专业知识的增加可能与自闭症学者特殊能力的选择有关，也与非学者型自闭症患者（有或无典型语言的自闭症、阿斯伯格综合征）明显表现的变异性有关。通常参与初级感知功能的脑区功能亢进可能解释了自闭症的感知内表型。
