Figure 4: Pupil responses and RT predict reductions in serial choice bias.
From: Pupil-linked arousal is driven by decision uncertainty and alters serial choice bias
(a) Serial choice bias, quantified as the history-dependent shift of the psychometric function, for tertiles of previous trial pupil responses. (b) Absolute choice bias, measured as the intercept of a logistic psychometric function, for tertiles of previous trial pupil responses. (c) Perceptual sensitivity, measured as the slope of a logistic psychometric function, for tertiles of previous trial pupil responses. (d) Lapse rate, measured as the probability of stimulus-independent guesses, for tertiles of previous trial pupil responses. (e) Post-error slowing, for tertiles of previous trial pupil responses. (f–j) as in a–e, but for tertiles of previous trial RT. ***P<0.001, *P<0.05, main effect of pupil/RT bin on repetition probability computed from a one-way repeated measures ANOVA. Unfilled markers indicate P>0.05, with Bf10 from a Bayesian repeated measures ANOVA written in panel. (N=27, group mean±s.e.m.).
