We thank Samuel Markowitz et al. for their interest in our work. Although the fixation patterns for each task in Figure 1 may appear similar, our statistical analysis gives quantitative and objective evidence that these fixation clusters are not in “the same retinal region,” nor are they from “the same continuum of oculomotor skills.” We agree with Dr. Markowitz et al. that one representative fixation point cannot be identified for all tasks and did not make this claim in the paper.
