Comparison of interception decision accuracy within each subject. A: difference in decision accuracy between trials in which eye velocity error was lower (lower bound) or higher (upper bound) than the median value for each observer (n = 24). B: difference in decision accuracy between trials in which initial saccade latency was earlier (lower bound) or later (upper bound) than the median value for each observer (n = 18). Gray lines show individual subject data; red thick line indicates group mean. Asterisks denote significant differences lower and upper bound: *P < 0.05, ***P < 0.001.
