Results from linear mixed-effects model of subjective and objective arousal responses to sounds. A) Boxplots display the age × arousal interaction. Crossbars represent medians and the upper and lower hinges correspond to first and third quartiles, respectively. B) A significant arousal × pupil interaction showed that pupil dilation evoked by arousing sounds were more associated with subjective ratings than pupil dilation evoked by non-arousing sounds. Lines and shaded areas represent regression fits and standard error, respectively. For both plots, each dot represents a participant.
