“I am” versus “we are”: Effects of distinctive variants of self-talk on efficacy beliefs and motor performance

The Effects of Positive Versus Negative Self-Talk on Vertical Jump in Soccer Players: The Moderating Role of Need for Cognition

The current study analyzed the effects of positive versus negative self-talk on physical performance in soccer players from a multiprocess approach. We operationalized the process distinction using the need-for-cognition (NC) construct. Thus, NC was measured and self-talk (i.e., positive vs. negative) was manipulated between participants (i.e., 126 soccer players, age 18 years or older, who were competing in national, regional, or local competitions). Physical performance was assessed by a vertical-jump test. According to hypothesis, regression analyses indicated that positive versus negative self-talk influenced physical performance to a greater extent for high-NC individuals than for low-NC individuals. Specifically, among high-NC soccer players, relative to baseline, positive self-talk produced greater physical performance in the vertical-jump test than negative self-talk. In contrast, among low-NC soccer players, no difference was found between positive and negative self-talk on physical performance. These results supported the moderating role of NC.

To me, to you: How you say things matters for endurance performance

Self-talk enhances physical performance. Nothing is known however about the way that a subtle grammatical difference in self-talk, using first or second person pronouns, may effect performance. As second person self-talk supports self-regulation in non-exercise populations, we hypothesized that 10 km cycling time-trial performance would be superior following second versus first person self-talk. Using a randomized, counterbalanced, crossover design, sixteen physically active males (M_age = 21.99, SD = 3.04 years) completed a familiarization visit followed by a 10 km time-trial during two separate experimental visits using first and second person self-talk. A paired t-test revealed that second person self-talk generated significantly faster time-trial performance than first person self-talk (p = .014). This was reflected in a significantly greater power output throughout the time-trial when using second person self-talk (p = .03), despite RPE remaining similar between conditions (p = .75). This is the first evidence that strategically using grammatical pronouns when implementing self-talk can influence physical performance providing practitioners with a new aspect to consider when developing interventions. We discussed findings in the context of a self-distancing phenomenon induced by the use second person pronouns.

The Effects of Overt Head Movements on Physical Performance After Positive Versus Negative Self-Talk

Research on self-talk has found that what athletes say to themselves influences their performance in sport settings. This experiment analyzed the relationship between positive and negative self-talk and physical performance in light of another variable: overt head movements. Participants were randomly assigned to first generate and then listen to either positive or negative self-statements. They were then randomly assigned to nod (up and down) or to shake (side to side) their heads while being exposed to the self-statements they had previously generated. Finally, physical performance was assessed using a vertical-jump task, a squat test, and a deadlift task. As expected, positive self-statements led to better performance than negative self-statements in 2 out of 3 physical tasks. Most relevant, the main effect of self-talk was significantly qualified by head movements. Consistent with the authors' hypothesis, athletes' self-statements were significantly more impactful on physical performance in the head-nodding condition than in the head-shaking condition.
