Interaction between phonemic and prosodic perception in cochlear implant users

Music Perception in Cochlear Implant Users

Temporal Feature Perception in Cochlear Implant Users

For the perception of timbre of a musical instrument, the attack time is known to hold crucial information. The first 50 to 150 ms of sound onset reflect the excitation mechanism, which generates the sound. Since auditory processing and music perception in particular are known to be hampered in cochlear implant (CI) users, we conducted an electroencephalography (EEG) study with an oddball parad...

Environmental sound perception of cochlear implant users.

The purposes of this study were (1) to develop a new test of environmental sound perception, the Environmental Sounds Perception Test (EST), (2) to compare the performance of experienced cochlear implant (CI) recipients with that of age-equivalent normally hearing (NH) listeners using this new test, and (3) to pilot test its clinical use as a pre-to-post assessment tool. The closed-set EST cons...

Perception and Psychoacoustics of Speech in Cochlear Implant Users

Cochlear implants (CIs) are prosthetic devices that restore hearing in deaf individuals via electric stimulation of the auditory nerve through an electrode array inserted in the cochlea. The device consists of a microphone and an externally worn speech processor that converts acoustic signals into electric signals. The speech signal coded with electric pulses is then delivered via a wireless tr...

Cross-modal reorganization and speech perception in cochlear implant users.

Recent work suggests that once the auditory cortex of deaf persons has been reorganized by cross-modal plasticity, it can no longer respond to signals from a cochlear implant (CI) installed subsequently. To further examine this issue, we compared the evoked potentials involved in the processing of visual stimuli between CI users and hearing controls. The stimuli were concentric circles replaced...
