N1 - The study extended Edwards et al. (2008) by examining self-talk effects in a healthy sample, contributing to an understanding of self-talk mechanisms in untrained individuals. Theoretically, the study also provided data questioning the matching hypothesis and indicating that Wulf?s (2001) attentional focus hypothesis may provide a better explanation to guide practice.

N2 - The purpose of this study was to investigate the effects of instructional and motivational self-talk on performance and the kinematics of the vertical jump. After completing a 10-minute warm-up on a stationary bike, 12 men (mean 6 SD; 20.8 6 3.0 years, 77.8 6 13.5 kg, 1.78 6 0.07 m) and 12 women (22.1 6 5.8 years, 62.6 6 6.7 kg, 1.65 6 0.05 m) performed 4 vertical jumps, 3 minutes apart, on a force plate set at a 1000-Hz sampling frequency. Before each trial, participants engaged in 1 of 4 counterbalanced interventions, verbalized out loud, which included motivational self-talk, instructional self-talk, neutral self-talk, or no instruction. One-way analysis of variance with repeated measures, followed by paired t-tests with a Bonferroni adjustment, were used to analyze data. Both instructional (0.415 m) and motivational (0.414 m) self-talk led to greater center-of-mass displacement than neutral self-talk (0.403 m, p = 0.001 and 0.003, respectively, alpha set at 0.008). Both instructional (263.9 N.s) and motivational self-talk (261.2 N.s) led to greater impulse than neutral self-talk (254.1 N.s, p = 0.005 and 0.004, respectively, alpha set at 0.025). Both instructional self-talk (582.6..s21 ) and motivational self-talk (592.3..s21 ) led to quicker angular rotation about the knee than neutral self-talk (565.8..s21 , p = 0.001 and 0.018, respectively, alpha set at 0.025). These results may indicate that self-talk leads to greater angular velocity about the knee, thus generating greater impulse and increased jump height a conjecture that needs empirical testing. Self-talk may contribute to improved performance in sports requiring power-based skills.
