This study investigated pupillary and behavioral responses to an emotional word valence identification paradigm among 32 pre-/early pubertal and 34 mid -/late pubertal typically developing children and adolescents. Participants were asked to identify the valence of positive, negative, and neutral word while pupil dilation was assessed using an eyetracker. Mid-/late pubertal children showed greater peak pupillary reactivity to words presented during tha emotional word identification task than pre-/early pubertal children, regardless of word valence. Mid late pubertal children also showed smaller sustained pupil dilation than pre early pubertal children after the word was no longer on screen. these findings were replicated controlling for participants age. in addition, mid late pubertal children had faster reaction times to all words, and rated themshelves as more emotional during their laboratory visit compared to pre early pubertal children. greater recall of emotional words following the task was associated with mid late pubertal status and greater recall of emotional words was also associate with higher peak pupil dilation. these results provide physiological, behavioral and subjective evidence consistent with a model of puberty-specific changes in neurobehavioral systems underpinning emotional reactivity.
