The main purpose of this study was to examine the efficacy of a strategy that combined self talk and performance feedback. Therefore, three groups of adult tennis players performed a forehand groundstroke task. The first group (n = 16) applied an instructional self talk and self feedback combination, the second (n = 16) used regular instructional self talk, and the third (n = 16) performed without any specific aid. The hypothesis was that the performance and concentration scores of both self talk groups would improve from the pretest to the posttest, while the scores from the control group would remain unchanged. The analysis of variance with repeated measures confirmed this hypothesis. Further, the players who used self feedback perceived the effectiveness of their intervention to be significantly higher compared with the other intervention group. Overall, the combination of self talk and feedback seems to be an alternative to the original instructional self talk intervention.
