The quiet eye: The influence of motor priming during a ball tossing task
The present study examined whether motor priming impacts the performance on a ball tossing task as well as corresponding quiet eye behavior. The study examined participants' (n= 22) toss performance and observed participants' (n = 18) quiet eye behaviors while performing a seated underhanded ball toss. The study consisted of an acquisition phase, in which the participants practiced the ball toss, and a test phase (pre-test, post-test, and retention). During the acquisition phase, participants practiced tossing balls to two targets (near and far target). For each toss, if the ball landed near the target (i.e., successful toss), an audible feedback tone would be immediately played. Each target (short and long) was associated with distinct auditory tones. During the test phase, participants performed the ball tossing task under two test conditions. During the priming test condition, participants were presented with the auditory tones associated with the targets during learning. Upon hearing the tone, the participant was to toss the ball to the associated target. During the control condition, participants were verbally instructed which target to toss to. Results revealed increased tossing accuracy for successful learners to the long target when primed with the associated auditory feedback. Furthermore, priming also had a weak but significant influence on quiet eye duration. Interestingly, priming of the toss performance resulted in a decreased quiet eye duration.
