Metacognition has been described as “having knowledge or awareness of one’s own cognitive processes” (Statt, 1998). This ability underpins both monitoring and control mechanisms in human thinking (Nelson & Nahren, 1994). Although extensively utilised within the realm of education and learning (c.f. Hacker, Dunlowsky & Graesser, 1998), the concept of metacognition is also pertinent to Psychological Skills Training in the realm of sport. Sport Psychologists primarily help athletes make improvements in their sport performance and this process involves both self reflection and self regulation strategies. As part of the symposium on Metacognition in Sport, the presenter will aim to show how PST is essentially a metacognitive endeavour. A framework based upon the work of John Flavell, for understanding and applying the concept, will also be applied to PST. Finally, problems with engagement in PST will be examined from a metacognitive perspective.
