The inducing effect of emotion is crucial to the regulation of the body's attention,and it is also an important issue in recent cognitive neuroscience researches.Behavioral studies on emotion aftereffect and ERP experiments have confirmed that when the former stimulus with emotional information,the recognition of subsequent stimulus will be disturbed.Although a large number of studies have indicated the existence of emotional aftereffect,their specific regulatory mechanism and regulatory strategies are still not clear.Therefore,our article used three behavioral experiments to interpret the emotional aftereffect on attentional resource between different types of stimuli.Based on the above conclusions,this paper used the variant of dual-task paradigm and the three-task paradigm to explore the regulation of attentional resource by emotional aftereffect.The previous two experiments mainly involved the identification of the central letters or peripheral facial emotions following induced stimuli in dual-task recognition.In the three-task recognition,we focused on whether recognition of parallel center letters and peripheral facial emotions after the emotional picture have been influenced.Participants were required to pay attention to the center during the experiment,then we could investigate the different allocation of attentional resource between different cognitive tasks,and the aftereffect by different emotions.The experimental results showed that,compared with the recognition rate of the central single task and the peripheral single task,the recognition rate of the corresponding stimuli in the dual-task has decreased,and the recognition rate of facial emotion has decreased significantly.In the three-task,there was no significant difference between the recognition rate of the center letter and the peripheral face.In the three-tasks and the dual-task,when the induced picture is negative,the recognition rate of the subsequent negative face was higher than the positive face.Our results indicated that,we verified the existing conclusion: the emotional information that appeared peripheral region could be perceived well,and there is a specific channel to process emotional information.Simultaneously,we could regulate the attentional resource through assesed the complexity of the task.The most important is that this study first demonstrated that the emotional aftereffect will seriouslyinterfere with the distribution of attention,mainly based on: task type and emotional type.The recognition of facial emotion will be seriously disturbed by emotional aftereffect which was divided to two levels: positive and negative.Compared to positive emotion,it is easier to activate the perception of negative stimuli when the induced stimuli concerning negative emotion.Positive emotional stimuli are more likely to be interfered by other emotional issue,and it's difficult to escape negative emotion.The conclusion of this paper analyzed the allocation mechanism of attentional resource from the perspective of emotional aftereffect,and helped us to understand the cognitive process of body more deeply.
