Vocal Emotion Communication With Cochlear Implants
Perception and Production of Emotional Prosody With Cochlear Implants
Father Flanagan's Boys' Home
255 participants
Jul 1, 2022
INTERVENTIONAL
Conditions
Summary
Patients with hearing loss who use cochlear implants (CIs) show significant deficits and strong unexplained intersubject variability in their perception and production of spoken emotions in speech. This project will investigate the hypothesis that "cue-weighting", or how patients utilize the different acoustic cues to emotion, accounts for significant variance in emotional communication with CIs. The results will focus on children with CIs, but parallel measures in postlingually deaf adults with CIs will be made, ensuring that results of these studies benefit social communication by CI patients across the lifespan by informing the development of technological innovations and improved clinical protocols.

Interventions
Using novel methodologies and stimuli comprising both controlled laboratory recordings and materials culled from databases of ecologically valid speech emotions (e.g., from publicly available podcasts), the team aims to collect perceptual data to build a statistical model to test the hypothesis that experience-based changes in emotion identification by pediatric and adult CI recipients is mediated by improvements in cue-optimization.
The team will acoustically analyze vocal emotion productions by participants, quantify acoustic features of spoken emotions, and obtain behavioral measures of how well normally hearing listeners can identify those emotions.
