Assessing the Effects of Depressed Mood and Cognitive Control Training on Memory Confidence and Accuracy Following Repeated Checking

摘要

Studies show that repeated checking leads to memory distrust in healthy controls. Additionally, the extent of this reduction in memory confidence has been associated with executive control. Utilizing a 2 x 2 design, we examine the role of mood and cognitive training targeting executive control on memory distrust following repeated checking. Participants were 69 individuals with depressed (n = 32) or euthymic (n = 37) mood. Memory distrust following a repeated checking task was assessed before and after 3 sessions of a computerized cognitive training program or a control task. Consistent with previous studies, participants reported reduced meta-memory following repeated checking. Although participants with depressed mood reported lower overall cognitive confidence at a trend level, the effect of repeated checking on memory distrust was not potentiated by depressed mood in our study. A reduction in memory distrust following repeated checking was found over time; however, this effect was not dependent on cognitive training condition, mood status, or their interaction.
