Fig. 6.

A: relationship between timing decision accuracy and relative eye velocity during maintenance phase. Each circle represents an observer. Asterisk denotes significant regression results: *P < 0.05. B and C: relationship between horizontal timing error and relative eye velocity for two representative observers. Each circle represents a single trial. D: correlation coefficient r between horizontal timing error and relative eye velocity of each observer. Mean correlation coefficient is significantly different from zero denoted by asterisks. ***P < 0.001.
