The present study tested the assumption that the momentary level of self-control strength affects the accuracy rates in a sports-related judgment and decision-making task.A total of N = 27 participants rated the veracity of 28 video-taped statements of soccer players who were interviewed by a non-visible referee after a critical Supplements for Men game-related situation.In half of the videos, the players were lying, and in the other half, they were telling the truth.Participants were tested twice: once with temporarily depleted self-control strength and once with temporarily available self-control strength (order counterbalanced; measurements separated by exactly 7 days).

Self-control strength was experimentally manipulated with the Stroop task.In line with two-process models of information processing, we hypothesized that under ego depletion, information is processed in a rather heuristic manner, leading to lower accuracy rates.Contrary to our expectations, the level of temporarily available Highlighters self-control strength did not have an effect on accuracy rates.Limitations and implications for future research endeavors are discussed.
