The current study replicates self-regulation research done by Schmeichel and Vohs (2009). In their study, they developed an intervention utilizing self-affirmations and high-level mental construal priming to restore self-regulatory resources. The current study employed the same intervention and took on new ground by applying it toward restoring self-regulatory resources in physical activity. Individuals were tested to see for how long they could do a wall-sit exercise, a common lower body exercise. Participants performed a pre-test measure of the wall-sit, and then they were ego depleted (drained of their self-regulatory resources) by doing a writing task. Afterwards, participants completed an intervention (or no intervention) and were then asked to perform a post-test wall-sit to measure the effect of the intervention and ego depletion. It was expected that participants who underwent ego depletion and a high-level affirmation intervention would display the most improvement on their wall-sits. However, this was not supported in the results as neither main effects nor the interaction were found to be significant. Therefore, the results do not support past research. Although the current study was conducted similarly to Schmeichel and Vohs' (2009) work, there were still major differences between them, and any of these differences could have caused variations in the results. Overall, it is likely significant findings were not achieved because the methods seemed to not produce enough incentive for participants to self-regulate to their best ability on the wall-sit. Future directions are discussed.
