Asymmetrical characteristics of emotional responses to pictures and sounds: Evidence from pupillometry
Fig 5
The velocity of pupil dilation.
(a) Gradient values of the pupillary response to the IAPS pictures for each condition in Experiment 1. (b) Gradient values of the pupillary response to the IADS sounds for each condition in Experiment 2. Error bars show standard error of the mean across the participants. Asterisks in (b) indicate a significant difference based on multiple comparisons for the interaction between the stimulus condition and the task condition; * p < 0.05, ** p < 0.01, *** p < 0.005.
