AbstractAn influential theory of self-control suggests that people have a finite store of self-control resources and as these resources are spent, individuals are prone to self-control failure (Baumeister et al., 1998). Self-control over goal attainment is compromised when self-control resources have been depleted (Hagger et al., 2010), but has been shown to be more successful when one has concrete action plans or implementation intentions (Gollwitzer & Sheeran, 2006). In the construal level theory, a concrete (implementation) mindset is associated with means-related (i.e., how to perform a behaviour) details and can be primed using an exemplar task (Trope & Liberman, 2003). The purpose of this study was to investigate if a concrete construal mindset would affect self-controlled performance during an effortful cycling task. Participants (N= 67) were separated into 4 groups in a randomized 2X2 design. Participants first completed either a self-control depleting task (modified Stroop task) or quiet rest control task. They were then given a priming task to induce either a high or low construal mindset. The main outcome measure was the amount of work (watts) generated at 1-minute intervals during a 10-minute cycling task performed at a constant level of perceived exertion (i.e., rating of 15 on Borg’s 6-20 RPE scale). Result showed a significant 3-way (Stroop X construal X time) interaction (p = .014). Analysis of simple effects showed performance deterioration over the course of the cycling trial in the depleted high construal group. In contrast, the depleted low construal group performed consistently over time at the same level as the high construal non-depleted group. Results suggest that concrete action representations support effortful performance when self-control resources are low. Findings have implications for athletic performance and lifestyle exercise behaviours that require self-control.
