Brief summary
Pitch perception and memory are central in auditory cognition, in particular for sound source segregation and recognition, speech prosody and music processing. Here the investigator assess pitch perception and memory in hearing-impaired listeners wearing cochlear implant(s) and listeners with congenital amusia, both compared with control listeners. Behavioral, EEG, and MEG measures are collected in audio and audio-visual contexts to characterize pitch processing deficits, and test a pitch training program.
Interventions
BEHAVIORALListening tests. Pitch training protocol
The two training protocols consists of perceptual tasks (auditory or visual exercises) performed repetitively using a tablet. Each protocol consists in 30 sessions of \ 20 minutes performed at home over a period of 15 weeks.
BEHAVIORALvisuo-spatial training protocol
The two training protocols consists of perceptual tasks (auditory or visual exercises) performed repetitively using a tablet. Each protocol consists in 30 sessions of \ 20 minutes performed at home over a period of 15 weeks.
BEHAVIORALEEG/MEG/MRI recordings.
