This study examined whether self-monitoring invokes other-knowledge reference by using task-faciliation paradigm(klein, Loftus, & Burton, 1989). Nineteen participants performed a series of tasks, which were other-reference("Does the word describe the friend?"), evaluative("Is the word socially desirable?"), self-monitoring("Does the word make you pleasant?"), and semantic("Is it difficult to define the word?"). Trials for each task were divided into four conditions by the type of the previous task. Comparisons among these condition showed that reaction times were shorter when the previous tasks and current tasks were the same than when they were different. the time required for the other-knowledge reference task was the same regardless of whether it was preceeded by the self-monitoring task of by the semantic task. considering with the results of Nakao and Miyatani(2005b), which showed the facilitation of self-knowledge referent task after self-monitoring task, our results revealed that self-monitoring is associated with characteristic traits of the self, but does not invoke ohter-knowledge reference.
