The purpose of this study is to identify patterns and differences in voice emotion recognition within cochlear implant (CI) users when certain prosodic cues are manipulated. The target sample in this study is 25 cochlear implant users as well as a control group of 25 adults with normal hearing. The recruitment is to occur within Gallaudet University by posting recruitment material in Gallaudet's Daily Digest as well as contacting Hearing Loss Association of American (HLAA). Prior to testing, participants will complete an online questionnaire regarding background information such as age of implantation, type of cochlear implant, onset of hearing loss, etc. In the lab, participants will listen to a variety of sentences spoken by a male and female speaker that will portray four different emotions: happiness, sadness, anger, and neutral. The sentences will be be manipulated in pitch, duration, and intensity and the listener chooses which emotion is conveyed from a closed set based on these prosodic cues. The time required for each participant should be about 1.5 hours. Results will portray which prosodic cue (pitch, duration, or intensity) is most important for detecting emotions in cochlear implant users and individuals with normal hearing.
