Self-advantage In Switching Task

In order to investigate the self-advantage in dynamic and shifty tasks, this studyintroduced the switching-task paradigm to explore. The Experiment1used the classicalstimulus faces as materials, and the results showed that when switching familiar-unfamiliartask to self-other task, self face was zero switching cost, which proved the self advantage.To get ride of the interference of face familiarity, experiment2brought in theshape-association paradigm to complete the same task. In the results, the switching costbecame purer—the cost of stranger had difference between the double switching tasks, andself appeared negative cost when switching to the self-other task. The negative costillustrated that the self-advantage in switching task cancelled out the cost of switchingprocedure. Experiment3employed Event-related Potential to explore the nerve mechanismof self processing in switching task. The results of brain waves showed that there had beenthe activation of frontal lobe and parietal lobe in the switching task, and the activation inthe interior of switching tasks existed difference nearby100ms. And all the three stimuluswere separate between two switching tasks. More importantly, self, friend and strangerseparated more obviously after300ms, and self shape disappearing specificity may be thereason of behavior difference. Consequently, self owned the unique cognitive process inswitching task.
