FIGURE 5.

Rats can flexibly prioritize either speed or accuracy depending on task contingencies. (A) Median decision time (DT) on the exemplar discrimination, as a function of the duration of the error penalty for two rats (black, gray). Both correct trials and errors had higher DT when penalty was longer; all trials are included in the analysis shown. Error bars show standard errors of the means (SEM). DT is defined as the observed reaction time (RT) minus the rat’s estimated motor latency (lifetime minimum reaction time). This subtracted constant was 0.403 (black) or 0.363 s (gray). For raw reaction time values see Figure 6. (B) Accuracy of discriminations in the same trials analyzed in panel (A). Error bars show 95% binomial confidence intervals.
