Proportion of fixations on relevant items in experiment 2.

The proportion of fixations on relevant items for each cue type and array size are plotted over the number of relevant colors in the array. Cue type has the largest effect on guidance of gaze towards relevant items, with positive cues being more effective than negative cues, which in turn are more effective than neutral cues. Array size modulates this, so that with larger arrays, gaze is guided towards relevant items more efficiently.
