Abstract
Source monitoring is defined as making attributions about the origin of a memory. In this study, the researchers investigated the causal relationship between working memory and source monitoring by giving adult participants the verbal dual task and affecting their working memory. It was predicted that the verbal dual task would hinder the functioning of working memory and affect source monitoring. Forty university students participated in this study. A half of them were randomly assigned to an experimental condition, and the other half to a control condition. All the participants completed working memory tasks. They also did source monitoring tasks twice in the first and second sessions. In the second session a verbal dual task was given to participants only in the experimental condition. It was found that the verbal dual task hindered the source monitoring performance.
