Behavior inhibition,as the core content of executive function,is the suppression of irrelevant information or behavior in order to complete tasks. Its early defects can easily lead to social communication disorders,working memory,emotional regulation,attention and other executive function problems. With the deeper understanding of behavioral inhibition,a series of mature test methods have emerged,including Stroop task,lateral inhibition,Navon task,Simon task,multi-source conflict task,etc. These behavioral inhibition test methods play an important role in the diagnosis of behavioral disorders. The development of executive function can be promoted by behavioral inhibition training for developing children. The early stage of behavioral inhibition healthy development can effectively improve children's self-control and attention,thereby improving the learning ability. Therefore,it is important to understand the test methods and behavior training of behavior inhibition for promoting the development of children's executive function.
