The influence of self-talk on the performance of skilled female tennis players

Abstract This paper reports on the development and implementation of a self-talk (ST) strategy designed to improve the volleying skill of collegiate tennis players (N = 5). A two-word ST strategy was developed, implemented, and evaluated using a single-case, multiple-baseline design. Dependent measures were movement patterns and outcome scores. After intervention, four players displayed immediate, positive changes with no overlapping datapoints on movement patterns. Notable improvements in outcome scores were also observed in all players, however, overlapping datapoints occurred for three players. Visual inspection of plotted values was supplemented by quantitative analysis using one-way ANOVAs to analyze four datapoints: the two baseline days just prior to intervention, and the two days immediately post intervention. Significant differences were found between phases, with both movement pattern and outcome scores higher following intervention. Qualitative data were collected via surveys and interviews. Players reported increased confidence following intervention, and offered explanations for its success conforming to theoretical positions that ST directs attentional focus and can prompt movement patterns.
