Model evaluation of predicted initial saccade direction for exemplar and categorical search trials in which saccades were not directed initially to the target. a, Box and whisker plots comparing WTA, MASC-T, MASC-T.S, and a Subject model in their ability to predict initial saccade direction on difficult exemplar search trials. The proportion of agreement in initial saccade direction is calculated between participants and each model and averaged over trials in which the target was not the first fixated object. The dashed line indicates the chance level of agreement based on 45° angular segments and a random direction of initial saccades. b, A similar model evaluation performed for categorical search.
