Prior research has shown that non-verbal behavior (e.g., overt head movements) can moderate the effects of positive and negative self-talk on physical performance. In the current studies, we aimed to extend existing research on self-talk by examining a different non-verbal behavior (i.e., body posture), as well as specifying some conditions under which body posture can interact with self-talk on physical performance from the Self-Validation Theory perspective. Most importantly, we proposed and tested a moderated serial multiple mediation model. In Studies 1 and 2, self-talk (i.e., positive vs. negative) and body posture (i.e., upright vs. slumped) were manipulated between participants. In Study 1, soccer players performed slalom and dribbling tests. In Study 2, athletes performed a push-up test. We hypothesized and found that positive (vs. negative) self-talk influenced physical performance to a greater extent for participants in the upright posture (i.e., validating) condition than for participants in the slumped posture (i.e., invalidating) condition. Furthermore, Study 3 was designed to analyze a moderated serial multiple mediation model. In this third study, self-talk was positive, body posture was manipulated, and the meaning of body posture was measured as a moderator. Results supported the proposed model, identifying the perceived validity of self-statements (i.e., the self-validation mechanism) and self-efficacy as serial mediators. That is, the meaning (i.e., validity-invalidity) moderated the effects of body posture on athletes’ physical performance in a pull-up test, through the indirect effects of the perceived validity of selfstatements and self-efficacy. Implications for self-talk research and application are discussed
