Experimental Study On ADHD Children’s Attention Network Under Different Emotional States

The relationship between attention and emotion has been studied extensively in cognitive science and neuroscience.Posner and colleagues have presented the attention Processing theory model-Attention Network Theory.They proposed that the attention system includes three attentional networks: alerting,orienting, and executive attention.These attentional networks throughout the entire attentional processing.On the basis of this, Fan and collaborators developed the Attention Network Test(ANT).The ANT has recently been widely used to study the impairment of attention Processing of children with ADHD. By inducing ADHD children and normal children with three stimulus emotionality(positives emotion, negative emotions and neutral emotions) and comparing performances among ADHD-I children,ADHD-C children and normal children in attentional networks under the three kinds of emotional state,the aim of the current research was to examine the characteristics of ADHD-I children and ADHD-C children in attentional networks and the influence of stimulus emotionality on attention in three attentional networks: alerting, orienting, and executive functions. This study includes the following three behavior experiments.This study included three experiments: Under the positive emotional states,Research one mainly inspect characteristic of two subtypes ADHD children in three attentional networks( alerting, orienting, and executive functions)through ANT-I task. Under the positive emotional states,Research one mainly inspect characteristic of two subtypes ADHD children in three attentional networks( alerting, orienting, and executive functions)through ANT-I task. Under the negative emotional states,Research two mainly inspect characteristic of two subtypes ADHD children in three attentional networks( alerting, orienting, and executive functions)through ANT-I task.In conclusion, this studies the following conclusions:(1)Orienting, and executive functions of ADHD children has a certain degree of lag behind.In Orienting, and executive functions,ADHD-I children is slower than ADHD-C children.(2)Emotional stimuli interfere on orienting network.Positive emotions improve the quality of execution control level, negative emotions have a promoting effect on executive function, but for the interference suppression function is.(3)Emotional stimuli have interference effects on ADHD children, make its accuracy is lower and more slowly. Emotional stimuli interfere with ADHD-C children and execution speed control accuracy, emotional incentive to ADHD-I children in pay attention to prolong the reaction time on the network to ensure the accuracy of the information.
