Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In previous studies, the Principal Investigator (PI) and the PI's team conducted foundational research that provided valuable information about key predictors of vocal emotion perception and production by pediatric CI recipients. The work proposed here will use novel methodologies to investigate how the specific acoustic cues used in emotion recognition by CI patients change with increasing device experience (Aim 1) and how the specific cues emphasized in vocal emotion productions by CI patients change with increasing device experience (Aim 2). Studies will include both a cross-sectional and a longitudinal approach.
The team's long-term goal is to improve emotional communication by CI users. The overall objectives of this application are to address critical gaps in knowledge by elucidating how cue-utilization (the reliance on different acoustic cues) for vocal emotion perception (Aim 1) and production (Aim 2) are shaped by CI experience. The knowledge gained from these studies will provide the evidence-base to support the development of clinical protocols that support emotional communication by pediatric CI recipients, and will thus benefit quality of life for CI users.
The hypotheses to be tested are: \[H1\] that cue-weighting accounts significantly for inter-subject variations in vocal emotion identification by CI users; \[H2\] that optimization of cue-weighting patterns is the mechanism by which predictors such as the duration of device experience and age at implantation benefit vocal emotion identification; and \[H3\] that in children with CIs, the ability to utilize voice pitch cues to emotion, together with early auditory experience (e.g., age at implantation and/or presence of usable hearing at birth) account significantly for inter-subject variation in emotional productions. The two Specific Aims will test these hypotheses while taking into account other factors such as cognitive and socioeconomic status, theory of mind, and psychophysical sensitivity to individual prosodic cues.
This is a prospective design involving human subjects who are children and adults. The participants will perform two kinds of tasks: 1) listening tasks in which participants listen to speech or nonspeech sounds and make a judgment about it, interacting with a software program on a computer screen; and 2) speaking tasks, in which participants will read aloud a list of simple sentences in a happy way and a sad way or converse with a member of the research team, in which participants retell a picture book story or describe an activity of their choosing. Participants' speech will be recorded, analyzed for its acoustics, and also used as stimuli for listening tasks. In addition to these tasks, participants will also be invited to perform tests of cognition, vocabulary, and theory of mind.
Participants will not be assigned to groups, and no control group will be assigned, in any of the Aims. In parallel with cochlear implant patients, the team will test normally hearing listeners spanning a similar age range to provide information on how the intact auditory system processes emotional cues in speech in perception and in production. Effects of patient factors such as their hearing history, experience with their cochlear implant, and cognition will be investigated using regression-based models. All patients will be invited to participate in all studies, with no assignment, until the sample size target is met for the particular study. The order of tests will be randomized as appropriate to avoid order effects.

Study Groups

Vocal emotion communication by children and adults with cochlear implants or normal hearing
Participants will be native speakers of American English and include pediatric cochlear implant recipients with unilateral or bilateral devices aged 6-19 years, children with normal hearing aged 6-19 years, postlingually deaf adults with cochlear implants, and adults with normal hearing. In Aim 1 participants will listen to emotional speech sounds and identify the talker's intended emotion. In Aim 2 participants will be invited to produce emotional speech by reading out scripted materials or in a more naturalistic conversational setting.
Perception of acoustic cues to emotion
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.
Production of acoustic cues to emotion
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.
