Multitasking has become part of our life. Self-interruption and switching to another task become easier and more frequent. According to previous studies, however, most of the task-switching incurs a cognitive cost. This study investigated the benefit from task switching. In Study 1, participants performed two tasks were similar, and negative correlation between the number of task switching and performance were confirmed, this result is similar to previous studies. Study 2 has shown that, made a comparison of two conditions, between possible and impossible conditions in terms of task switching. Depending on switching preference, the result of task performance has differentiated and the emotion that participants had before the task has changed. Depending on participants' switching preference, there were different amount of switching cost. Moreover, for participants who preferred task switching highly than others, task switching occurred more benefit than cost.
