Let's See If You Can Hear: The Effect of Stimulus Type and Intensity to Pupil Diameter Response in Infants and Adults.

In experiment 2a, where young adults listened to warble tones in a detection task, the PDR to target trials as compared with standard trials showed marginally significant linear increase across the intensity levels, as we had hypothesized based on previous reports (Liao et al. 2016; Bala et al. 2019 ; Schilling et al. 2019 ), but the responses did not differ significantly from (adult) results in the discrimination tasks in experiments 1b and 2b.
