| Emotion plays a very important role in people’s social life.Early researches on emotion have never been stopped in psychology.In the early days,the exploration of emotion was based on the two dimensional model of emotion.In recent years,scholars have paid more attention on motivation.It proposed that motivation is the third dimension apart from valence and arouse,and the difference of motivation intensity could impact the cognitive processing of the individual.At the same time,with the rise of research on positive psychology,more and more scholars begin to explore the positive emotion.In this study,two experiments are conducted to explore the impact of different motivational intensity toward positive emotion on task switching to the individual and the moderating effect of task difficulty.Experiment 1 is based on the classification task,exploring the effects of different positive emotions of motivational intensity on the task switching of adolescents.In the reaction time,both time before and after task switching of high intensity conditions are significantly higher than that of the low strength;in the error rate,it has no significant difference in between under the two conditions of emotion;in the switch cost of reaction,it is significantly lower under the condition of positive emotion of low intensity than high;in the conversion loss of error rate,it has no significant difference in between.Experiment 2,basing on the experiment 1,uses the same paradigm to investigate whether task difficulty can adjust the effects of the different positive emotions on the task switching of adolescents.The results show that,in the easy task,the reaction time and error rate in the positive emotions of high intensity are significantly higher than those in the neutral one,and so as the switching cost;in the difficult task,two emotional reaction time and error rate had no significant difference,and so as the switching cost.The conclusions of this study are as follows:(1)The positive emotion of different motivational intensity can affect the task switching to the individual.Positive emotions of low intensity can promote their task switching,while positive emotions of high intensity hampers their task switching.(2)The difficulty of task can adjust influence of positive emotion of different motivational intensity towards task switching to the individual.In the easy task,positive emotion of high intensity,comparing with neutral emotional condition,is more likely to hamper the task switching to the individual. |
