孤独症谱系障碍儿童非典型人际同步表现及其神经机制

Atypical interpersonal synchronization and its neural mechanism in children with autism spectrum disorder

人际同步在个体构建社会交流系统的过程中发挥着重要作用,系统回顾文献发现孤独症谱系障碍(ASD)儿童在社会互动中,行为、认知和情感不同层面都表现出人际同步减少或中断。进一步的神经影像证据发现,ASD儿童与同伴之间大脑同步性协调反应降低或中断,较难实现内隐心理状态的共享和外显互动行为的同步。未来研究可能要从认知固化、行为不协调和情感表达失衡3个方面来构建ASD儿童非典型人际同步模型,并探索ASD儿童非典型人际同步是个体发育受损的产物,还是个体发育受损的潜在机制。

Interpersonal synchrony has been treated as a critical element to build up social communication system.Systematic study of neuroscience literature showed interpersonal synchrony decreased or disrupted at different levels for children who have been identified with autism spectrum disorder(ASD),including behavior level,intelligence level and emotional level.Furthermore,magnetoencephalography neuroimaging evidence has shown that there is reduction or interruption of brain synchronous coordination response between ASD children and peers.It is difficult to realize the sharing of implicit mental state and the synchronization of explicit interactive behavior.Future studies may propose modelling of interpersonal synchrony for ASD individual from three aspects,including cognitive solidification,behavioral disharmony and emotional expression imbalance,and explore whether the atypical interpersonal synchronization of ASD children is the product of impaired social function or the potential mechanism of impaired social function.
