Autism involves a basic impairment in social cognition. Abnormalities in social behavior coexist with aberrant attention and deficient language. In the attentional domain, attention to people and socially relevant stimuli is impaired. Also children with autism spectrum disorders (ASD) are characterized by impairments in face recognition and decreased attention to faces.
To review neurofunctional deficits underlying ASD by using event related potentials.
Event related potentials demonstrate that auditory orienting deficits in autism cannot be explained by sensory deficits and that the orienting deficit in autism might be speech-sound specific, suggesting deficits particularly in social orienting. In addition, children with ASD have a disordered pattern of brain responses to faces and objects at an early age.
自闭症涉及社会认知的基本缺陷。社会行为异常与注意力异常和语言缺陷并存。在注意力领域,对人和社会相关刺激的注意力受损。此外,自闭症谱系障碍(ASD)儿童的特征是面部识别受损和对面部的注意力下降。
通过使用事件相关电位来综述自闭症谱系障碍潜在的神经功能缺陷。
事件相关电位表明,自闭症的听觉定向缺陷不能用感觉缺陷来解释,自闭症的定向缺陷可能是语音特异性的,这表明特别是在社会定向方面存在缺陷。此外,自闭症谱系障碍儿童在幼年时对人脸和物体的大脑反应模式紊乱。
