Theodorakis et al. (2000) extended this approach by examining the influence of instructional versus motivational self-talk on various motor skills.
It was found that both self-talk strategies are effective on improving performance.
However, instructional self-talk was found to be more effective than motivational self-talk on fine motor skills, while both motivational and instructional self-talk to be equally effective on
motor skills requiring strength and endurance (Theodorakis et al., 2000).
