A: relationship between landing site error and perceptual judgments. Mean percentage of forward responses in each group is shown as a function of landing site error (distance between saccadic landing site and presaccadic target). For each observer, we divided the distribution of landing site errors into the same bins, ranging from −8° to 8° of the presaccadic target in increments of 0.5°, and calculated the percentage of forward reports for each bin. We subsequently fitted a weighted linear regression model to these data for each subject, weighting data points by the number of observations in each bin. For visualization purposes, we averaged the proportion of forward responses in each bin per group. Bins in which fewer than 2 participants per group contributed are not depicted. Error bars are SE. B: correlation between positive symptom severity and individual slopes of the function shown in A. Each circle corresponds to one SZP. PANSS, Positive and Negative Syndrome Scale; rs, Spearman's rho.
