Abstract

Task persistence can become problematic when individuals continue to perform challenging tasks unlikely to yield success. Instead, it may lead to frustration, burnout, and negative psychological outcomes. Recognizing when to disengage from these goals is essential for reallocating resources toward more attainable objectives by shifting focus to a new task rather than persisting on the same one. Ultimately, this promotes emotional well-being and resilience. No previous studies have experimentally examined the combined processes of disengagement and reengagement. This study investigates the temporal and causal effects of disengagement and subsequent reengagement with an alternative task, making it the first to experimentally test these dynamics. Task persistence was employed as the research paradigm to manipulate disengagement and reengagement techniques across four experimental conditions: disengagement, reengagement, a combination of both, or a control group. The tasks involved solving difficult anagrams. Participants initially worked on an anagram set for five minutes, followed by a three-minute manipulation period. After each manipulation, participants completed a five-minute task. Before the anagram task began, participants choose the category of anagrams they wanted to solve. This allowed researchers to assess how strategies impacted task selection, engagement, and performance. It was hypothesized that the combination of disengagement and reengagement would yield the highest performance outcomes. The results demonstrated that trait disengagement was a significant predictor of task performance. Individuals high in disengagement performed better, particularly in the absence of experimental manipulation. Experimental manipulations did not independently influence performance outcomes. Self-control was positively associated with resilience, suggesting individuals with greater self-regulation were better equipped to adapt to changing task demands. These findings stress the importance of self-control in maintaining psychological resilience, especially when navigating challenges requiring both persistence and flexibility. Additionally, self-control was positively associated with well-being and self-esteem, while reengagement played an essential role in promoting optimism and resilience. These findings suggest adaptability in goal pursuit is not solely about persistence but also about knowing when to disengage and reengage effectively. This research emphasizes the need for a balanced approach to resilience, recognizing the value of both letting go and pursuing new goals.
