Arousal-Cued global motion task.
Trial schematic illustrating our arousal-cued global motion task, in which an unexpected, masked disgusted face increased arousal just prior to a motion judgement and confidence rating. On each …

Overview of behavioral results.
(A) Manipulation of sensory precision; stimulus probability density functions show our low (15 σ) and high (25 σ) variance conditions; stimulus mean and variance were orthogonally manipulated using …

Figure 3 with 1 supplement
Pupillometry results.
(A) Results of general linear modelling (GLM) of pupil responses; the pupil grand mean response function shows a canonical orientation response, peaking during confidence rating before returning to …

Additional pupil effects of interest.
(A) Confidence is biphasically encoded in pupil responses, with a stimulus-locked dilatory effect and a rating-locked constriction effect. Cues (B, disgust > neutral) increased dilation from …
