Table 3.
(a) Average absolute number of distractor touches per run on medium (similar) and small (dissimilar) distractors, respectively and (b) proportion of targets of that type touched when search displays contained both types of distractor: heterogeneous displays with infrequent similar distractors or heterogeneous with infrequent dissimilar distractors
