| 520 3# - SUMMARY, ETC. | |
| Summary, etc | A better understanding of melodic pitch perception in cochlear implants (CIs) may guide signal<br/>processing and/or rehabilitation techniques to improve CI patients' music perception and<br/>appreciation. In this study, the mismatch negativity (MMN) in response to infrequent changes in<br/>five-tone pitch contours was obtained in CI users and normal hearing (NH) listeners. Melodic<br/>contour identification (MCI) was also measured. Results showed that MCI performance was<br/>poorer in CI subjects than in NH subjects; The MMNs were missing in all CI subjects for the 1-<br/>semitone contours. The MMNs with the 5-semitone contours were observed in a smaller<br/>proportion of CI subjects than in NH subjects. Results suggest that encoding of pitch contour<br/>changes in CI users appears to be degraded, most likely due to the limited pitch cues provided by<br/>the CI and deafness-related compromise of brain substrates. |
