Abstract
This study investigates the interactions between depression, self-referential process- ing (SRP), stickiness of mind-wandering, and their combined effects on memory recall accuracy within complex working memory (CWM) tasks. Depression has been linked to increased ”stickiness” in mind-wandering, defined as difficulty in diverting attention from spontaneous, self-generated thoughts. These sticky thoughts are often associated with impaired cognitive performance, particularly in tasks demanding high cognitive engagement. To explore these interactions, we utilized an existing dataset of English speakers from Siwen Sheng et al. (in preparation). The study examined how varying levels of depressive symptoms influence cognitive performance. Based on our literature review, we hypothesized that individuals with higher levels of depressive symptoms would exhibit lower memorization accuracy in complex working memory tasks due to increased stickiness of mind-wandering. We further hypothesized that this effect would be more pronounced in tasks involving the self condition compared to the shoebox condition. Our findings indicate that higher levels of depressive symptoms are associated with increased stickiness, which negatively impacts memory performance. However, in contrast to our hypothesis, the self condition did not significantly decrease recall accuracy compared to the shoebox condition. This suggests that while depression increases the stickiness of thoughts, it may not nece...
