ABSTRACT
For perceptual-cognitive skill training, a variety of intervention methods has been proposed, including the so-called "color-cueing method" which aims on superior gaze-path learning by applying visual markers. However, recent findings challenge this method, especially, with regards to its actual effects on gaze behavior. Consequently, after a preparatory study on the identification of appropriate visual cues for life-size displays, a perceptual-training experiment on decision-making in beach volleyball was conducted, contrasting two cueing interventions (functional vs. dysfunctional gaze path) with a conservative control condition (anticipation-related instructions). Gaze analyses revealed learning effects for the dysfunctional group only. Regarding decision-making, all groups showed enhanced performance with largest improvements for the control group followed by the functional and the dysfunctional group. Hence, the results confirm cueing effects on gaze behavior, but they also question its benefit for enhancing decision-making. However, before completely denying the method's value, optimisations should be checked regarding, for instance, cueing-pattern characteristics and gaze-related feedback.

Gaze-path index (GPI) (M and SE, in ° visual angle) as a function of group (functional, dysfunctional and control), test (pre-, post-, and retention test), and phase (P1 and P2). The dashed lines represent the values that were achieved if the gaze perfectly followed either the functional (lower line) or the dysfunctional (upper line) cue path.

Figure 5: Gaze-path index (GPI) (M and SE, in ° visual angle) as a function of group (functional, dysfunctional and control), test (pre-, post-, and retention test), and phase (P1 and P2). The dashed lines represent the values that were achieved if the gaze perfectly followed either the functional (lower line) or the dysfunctional (upper line) cue path.

Mentions: In Figure 5, the GPI is depicted as a function of group, test, and phase. The value of 0° on the vertical axis denotes the middle between the functional and dysfunctional cue paths, and the dashed lines correspond to the values a participant would achieve if he or she would exactly follow one of the two cue paths. As it can be taken from the dashed lines, on average, the two functional (negative values) and dysfunctional (positive values) paths are distinguished by a relatively large average distance over P1 (run-up: attacker vs. ball) and a relatively small average distance over P2 (attack: anticipated ball-hand-contact vs. ball). Descriptively, in the pre-test, all GPI values are closer to the functional than to the dysfunctional path. Values below the functional cue path in P2 denote that from jump initiation until ball-hand contact by the attacker participants tend to direct their gaze more to the attacker than to the point of the anticipated ball-hand contact, which is definitive for the gaze path that had been considered a priori as functional.
