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.
