- Abstract
Objective:. Adolescent cochlear implant (CI) users experience signficiantly more peer problems and higher bullying rates than peers with typical hearing (TH), which may stem from deficits in peer social dynamics. Successful social interactions require perception of not only message content, but also integration of sensory input to infer a speaker's emotion from visual (facial expressions) and auditory (prosody) cues. This study examines the effect of auditory status (CI vs. TH) on visual emotion recognition in adolescents. METHODS. Participants included 34 adolescents with CIs and 24 with TH. CI users had a mean age of 13.3 years, mean age at first CI of 2.7 years, and mean duration of CI use of 10.7 years. TH peers had a mean age of 13.7 years. All participants completed an emotion recognition task with static images of 4 individuals expressing 6 emotions (anger, disgust, fear, happy, sad, surprise). Participants labeled the emotion in the image from a closed-set list. We recorded mouse clicks to examine behavioral accuracy and reaction time, and eye movement patterns via eyetracking. Results: No significant group differences emerged for behavioral accuracy or reaction time for emotion recognition. However, eye tracking revealed differences relative to areas of the face on which each group fixated, with the CI group fixating longer on the mouth area across emotions compared to TH peers. Conclusions: Longer fixations on the mouth may represent a compensatory strategy to mitigate effects of a compromised CI signal, but it detracts attention from the eyes, which underscore conversation management and social interaction. Knowledge of the effect of CI on emotion recognition could lead to more effective, efficient therapeutic intervention related to social deficits in adolescents with CI.
