ATTENTIONAL PROCESSES AND CHOKING UNDER PRESSURE

The self-focus theory of choking under pressure explains decreases in performance of well-learned motor tasks with an increase in skill-focused attention. This shift in attentional focus has been demonstrated; however, specific propositions about the processes in pressure-induced attentional shift are yet to be developed. This study assesses whether specific aspects of movement execution attract more attention than others when movements are executed under pressure. Such elements are important in conscious movement control before execution becomes automated through practice; under pressure, attention may be redirected to these elements. Basketball free throws were executed by 22 junior national team members in a low and high pressure situation. Two dual task/focus conditions (related to different aspects of the movement) were implemented in each pressure condition. This dual task paradigm was used as a direct and detailed measure of skill focused attention, suitable to show specific pressure induced shifts of attention that lead to performance decrements. Pressure was induced by telling players that their performance would be evaluated by coaches. Players were defined as chokers if their performance decreased under this pressure. Chokers showed differences with regard to their attentional focus on movement execution in the pressure conditions compared to the players defined as non-chokers. The findings suggest that attentional shifts during choking can be related to specific aspects of movement execution.
