Pupil responses around word presentation and verbalization differentiate between good and poor memory trials. The diagram on the left shows subject-averaged pupil size aligned to the moment of word presentation, while the diagram on the right shows subject-averaged pupil size aligned to the beginning of word recall. Good trials (>4 words recalled) are depicted in blue, and poor trials (<5 words recalled) in red. The shaded regions indicate the standard error of the mean, and the black horizontal bars mark the time periods during which a significant effect of the trial type was observed in a given time bin (ANOVA, 1 d.f., p < 0.05). Notice the opposite pattern of pupil constriction and dilation, respectively, induced by memory encoding and recall.
