Effects of Task-switching on Proactive Control and Metamemory Regulation

Abstract

Past researchers have proposed a relationship between cognitive control and metamemory and several studies have provided the most support for a relationship between task-switching and metamemory regulation. Nevertheless, the evidence has been correlational. To my knowledge, the present study was the first to include an experimental manipulation incorporating a dual-task that required task-switching within a feeling of knowing (FOK) paradigm to directly observe the effects of task-switching on FOK accuracy. Research on cognitive control has demonstrated that engaging in proactive cognitive control typically leads to better performance in cognitive tasks and that young adults are naturally biased to engage in proactive control. Furthermore, cognitive control styles can be manipulated through a variety of means. I had a secondary interest in participants' metamemory awareness. Particularly if knowledge of task demands would lead participants to study word pairs longer in the dual-task block study phase relative to the single-task block study phase. The sample consisted of 191 healthy young adults (Mage = 19.34, SD = 1.57). I predicted that task switching would decrease FOK accuracy as well as the ability to engage in proactive control. These hypotheses were supported; however, study duration did not differ between the single and dual-task blocks. Importantly, the present study provided empirical evidence for a relationship between task-switching and metamemory regulation and provided a basis for which to further investigate this relationship.
