For each coherence, reaction time (mean ± SE) and number of trials (n) are listed for trials in which the monkey selected T1 (target in RF) or T2 (target outside of RF), correctly or in error (combined data from two monkeys). For the 0% coherence stimulus, there is no distinction between correct and error. Asterisks indicate that the reaction time on error trials differs from that on correct trials (p < 0.05; ANOVA).
