| Abstract | Trainability of visual search strategies on coloured displays and the impact of perceptual uniformity of the colour scale were assessed. Participants were asked to search for four targets in red-white-blue (RWB) displays while their eye movements were recorded. These displays were mainly composed of distracting noise and were designed to correspond to spatial frequencies traditionally encountered in geophysical data images. The present study replicates previous findings that perceptual uniformity is a necessary prerequisite for the spontaneous application of a colour-based search strategy in RWB displays. It is further demonstrated that the application of this strategy is even more pronounced when novice participants are trained with eye-movement patterns of an expert in geophysical data images. Half of the participants were therefore shown video recordings of the gaze position of an expert scanning the displays whereas the other half was shown a static presentation of the images. This brief training session of approximately 6-7 minutes was shown to encourage the use of a colour based search strategy on uniform displays whereas it had no effect for non-uniform displays. It was also shown to increase the search speed slightly but regardless of the colour scale used. The enhanced application of the search by colour strategy after training with eyemovement patterns corroborates the use of uniform colour scales and provides an easy-to-implement training method for further improving visual search behaviour. |
