Abstract

Quiet eye’ (QE) behaviour – a period of extended gaze fixation on a target – is found in many tasks that require accurate aiming. Longer quiet eye durations (QED) are reported in experts compared to non-experts and in more successful versus less successful trials. The facilitatory effects of the QE have been largely tested in the field and the cognitive mechanisms underlying the QE are not yet fully understood. We investigated the QEDs of 11 expert and 11 novice archers in the field and in the laboratory, using a simulated archery 11 task. On the latter task, we also compared QEDs between the archers and 10 non-archers, as controls. Our novel simulated task allowed for the controlled examination of the effects of task complexity and processing demands, which are known to modulate the duration of the QE. The simulated task consisted of shooting archery targets by using a joystick, in which random ‘noise’ (visual motion perturbation) was introduced at two levels: High and Low. Eye movements were measured using electro-oculography in both tasks. The expert archers exhibited longer QED compared to the novice archers in the field task. In the simulated task, the archers exhibited longer QEDs and were more accurate compared to non-archers. Furthermore, expert archers showed earlier QE onsets and thus, longer QEDs during High Noise conditions compared to the novices and non-archers and compared to the Low Noise condition. Our findings show skill-based effects on QED during a simulated archery task and suggest that the QE period involves attention control mechanisms and the incorporation of on-line feedback input into the process of motor programming.
