Study Of The Influence Of Task-switching Training To Emotion Regulation

Emotion is the attitude and experience that people make about whether objective things or situations satisfy their own wishes or needs.It is the psychological and physiological condition that people's multiple feelings,thoughts and behaviors react to synthesize.However,if those emotions become too strong and uncontrollable,this would have a negative impact on individuals' work and study.Therefore,effextive emotion regulation skills seems to be critical.So far,the existing methods are either complicated or expensive and the spread and promotion is limited.There is a lack of an easy-to-grasp,simple and practical method and a low cost method to improve the emotion regulation ability.Task-switching is one of the executive functions.It is a method used to evaluate cognitive function in the field of cognitive neuroscience.Recent researches show that it has potential as a cognitive training approach to improve the ability of emotion regulation.Meanwhile,the method has advantages of less complicated and less dificult and so on.Based on this,this study proposes a method of using task shift training to improve the ability of emotion regulation.In this study,20 subjects were screened by difficulties in emotion regulation scale and randomly divided into three groups-experimental group,control group and blank group.The experiment process included emotional regulation experiment and task-switching training.Experimental group completed emotional training and control group did non-emotion training whereas blank group didn't train.Data collected in this procedure were used in analysis of the impact of task-switching training on emotional regulation and task-switching training mechanism,the analysis results are as follows:Emotion regulation experiments before and after training were compared,and the positive effects of task training on emotion regulation experiments were validated: the reaction time of the experimental group was significantly shortened,the control group had a marked shortening trend,and the blank group did not change.Subject's subjective evaluation did not change.EEG data analysis showed that the late-positive components of the event-related potential of the control group decreased after training,and the relative power spectrum density of the experimental group and the control group differed greatly under different levels of valance and arousal.Event-related spectral perturbations showed that the brain under actively regulating and high-awakening conditions may be more sensitive to task-switching training.However,time-frequency power of experiment group increased and that of control group decreased.The behavioral and physiological analysis of the training process to explore brain mechanism of task-switching training: Behavioral results show that the experimental group and control group conversion task response time is longer than the repeat group,the time-frequency power changes and activation of the brain area share some same points and exist differences.The same point: both groups can activate the dorsolateral prefrontal cortex;different points: the control group activated a wider range of brain region and activation in experimental group was constrained in relatitive small area.Control group manifest significant activation in right temporal lobe while experimental group show the significant activation in left temporal lobe.This may be the main cause for the different physiological changes of emotion regulation experiment before and after training in experimental group and control group.The experiment concluded that the short-term task-switching training has an immediate effect on the ability of emotion regulation.The study of brain mechanism shows that there is some difference in the task-switching training with or without emotions.This research lays the foundation for further application of task-switching training.
