Introduction
The color-cueing intervention was introduced to enhance decision-making skills in nov-ices. However, the method’s functionality is under debate (e.g. Abernethy, et al., 2012) which might be explained by absent gaze learning (Klostermann et al., 2015). The current study controlled for possible confounding by non-matching gaze-path protocols (Exp1) and response modes (Exp2) over the intervention. Positive training effects were particu-larly expected with congruent training-testing conditions.
Methods
Novices were trained expert gaze paths by implementing color-cues in beach-volleyball-training videos. In Exp1, participants learned different gaze paths (S-verbal vs. S-action vs. S-control) with different response modes in Exp 2 (T-action vs. T-verbal). Decision-making performance was tested in pre-, post and retention tests with verbal (put down in writing) and action (recorded with VICON system, 200 Hz) response modes. Gaze behav-ior was recorded with an integrated eye-tracking system (EyeSeeCam, 220 Hz). As de-pendent variables, average response accuracy and the average gaze deviation to the ac-tion and verbal gaze paths were calculated and analyzed with ANOVAs and dependent t-tests.
Results
In both experiments, gaze deviation showed significant main effects for response mode (all ps < .01, all ηp2 < .28) with gaze being closer to the gaze path of the matching test condition irrespective of time of test and intervention type (all ps > .09, all ηp2 < .06). Fur-thermore, participants improved response accuracy over time in the verbal response mode in both experiments (all ps < .01, ηp2 > .25) and in the action response mode in Exp2 only (p < .01, ηp2 = .20) irrespective of intervention type (all ps > .77, all ηp2 < .03).
Discussion
The results emphasize that even perfectly matched intervention and test conditions can-not replicate the positive effects of color cueing on decision-making enhancement. How-ever, participants showed a test-specific gaze behavior with gaze paths closer to the matching test conditions corroborating the tight perception-action coupling.
