Brief Summary
Focusing attention is pertinent to the performance of closed self-paced motor tasks. The following study will examine the effectiveness of internal and external focus of attention instructions on the performance of a dart throwing task under rested and fatigue (after performing intense exercise) conditions. As well as the relationship between attentional focus instructions and gaze behavior under these two conditions.

Conditions
Outcome Measures
Primary Outcomes (3)
Absolute error
A measure of overall accuracy in performance - the distance from the target for each shot, without regard to direction
Two weeks
Variable error
Performance variability - the standard deviations of the cluster of target hits
Two weeks
Quiet eye duration
The length of time in milliseconds in which the performer's gaze is stable on the target
Two weeks
Secondary Outcomes (3)
Number of saccades
Two weeks
Number of fixations
Two weeks
Attentional focus comprehension
Two weeks
Study Arms (3)
External focus group
EXPERIMENTALThis group will be given instructions on how to focus on the external cue relevant to the task (e.g., focus on the center of the dart board).
Internal focus group
EXPERIMENTALThis group will be instructed how to focus on the arm movements (e.g., feel the bend in your elbow).
Control
NO INTERVENTIONThis group will be given general instructions on throwing techniques (e.g., hold the dart with four fingers and make sure it is in a stable position) but no attentional focus instructions will be given.
Interventions
The participants will learn the dart throwing task according to specific instructions. Participants in all groups will be given the same technical instructions on how to throw the dart. The technical instructions will be followed by attentional focus instructions that will differ between the groups.
