The Effect Factors On Task Switching In High Impulsive Person

The study used the task-cuing paradigm and changed various kinds of interference to research the effect of interferences on task switching in high impulsive person.This study consisted of three experiments. The first and second experiment was to examine the processing difference between tasks(difference between task difficulties; difference between task arousal)in high impulsive person; The three experiment was to turn to research the difference of interferences between tasks(size differences between tasks)in high impulsive person.The purpose of Experiment 1 was to investigate the difference of difficulty between tasks(easy tasks, hard tasks) on task switching in high impulsive person, results showed that the high impulsivity are easily to begin tasking switching; from the accuracy, the high impulsivity make more mistakes; Under the high task difficulty conditions, the high impulsive person used apparently shorter reaction time than the low impulsive person,however, under the low task difficulty conditions, there is no difference between them.The aim of Experiment 2 was to look into the difference of arousal between tasks(arousal low, arousal high)on task switching in high impulsive person, data showed that, the high impulsivity are bad than low impulsivity. When arousal low, the high impulsive person used shorter reaction time but made more mistakes; under the high arousal conditions, the high impulsive person made more mistakes than the low impulsive person.The purpose of Experiment 3 was to study the difference of interferences between tasks(size differences between tasks)in high impulsive person. From the outcomes, under the low interference conditions, the high impulsivity are more easily to process the task switching, but with the more mistakes, and the low impulsivity takes longer time to switch tasks with less mistakes.All in all, According to the data analysis, this study reached the following conclusions :(1) The high impulsivity are performed poor both reaction time and accuracy compare to the low impulsivity. They cost shorter reaction time and lower accuracy.(2) No matter under which conditions, difficulty difference, and arouse difference, interference difference, the high impulsivity are more easily to process the switch cost.(3) The difficult difference and the interference difference influenced the high impulsivity at the same way, but the high arouse influenced the high impulsivity apparently, especially for the high impulsive person under the high arousal conditions...
