Differences in the perceived music pleasantness between monolateral cochlear implanted and normal hearing children
Summary
Children with cochlear implants (CI) may experience music less pleasantly than normal-hearing children. EEG alpha asymmetry patterns suggest reduced pleasantness perception in monolateral CI users during music listening.
Area of Science:
- Neuroscience
- Audiology
- Music Perception
Background:
- Music perception is crucial for quality of life in cochlear implant (CI) users.
- Electroencephalography (EEG) rhythms, specifically alpha band frontal asymmetry, correlate with pleasantness perception in healthy individuals (approach-withdrawal theory).
Purpose of the Study:
- To compare EEG alpha band activity between monolateral CI children and normal-hearing children during music listening.
- To investigate differences in pleasantness perception of music between these two groups.
Main Methods:
- EEG data was recorded from monolateral CI children and a normal-hearing control group.
- Analysis focused on the alpha frequency band and frontal asymmetry patterns during music cartoon fruition.
Main Results:
- Normal-hearing children exhibited EEG alpha asymmetry patterns indicative of higher pleasantness perception compared to CI patients.
- Monolateral CI children showed different cerebral activity patterns during music listening.
Conclusions:
- Monolateral cochlear implant users may perceive music as less pleasant than their normal-hearing peers.
- EEG alpha asymmetry can serve as a biomarker for music pleasantness in CI populations.
