81O 043FINE STRUCTURE PROCESSING AND MUSIC PERCEPTION:IMPLICATIONS FOR PEDIATRIC COCHLEAR IMPLANTATIOND.R. Friedland, A.P. Johnson, C.L. RungeMedical College of Wisconsin, Otolaryngology and Communication Sciences, MILWAUKEE, USAE-MAIL: dfriedland@mcw.eduOBJECTIVES To identify whether processing strategy provides benefit for recognizingmusical instruments with a cochlear implant. METHODS Forty-nine normal hearing children and 21 children with cochlear im-plants were tested on a 6-choice musical instrument identification task.In addition, a similar instrument identification task was presented to 15adult cochlear implant users utilizing novel fine structure processing (FSP)and high definition continuous interleaved sampling (HDCIS) maps. RESULTS Normal hearing children reached adult levels of musical instrument iden-tification by around age 12 years. While implanted children improved theirinstrument identification performance with age, they performed wellbelow their age-matched normal hearing counterparts. The effect of pro-cessing strategy could not be adequately analyzed in children due to vari-ability in duration of implant use and the small sample size. Analysis ofperformance of adult subjects who routinely used FSP as their daily strat-egy showed they perform significantly better overall on a musical instru-ment identification task than those using HDCIS daily (p=0.03). CONCLUSION Children who develop with a cochlear implant as their principal access toauditory information do not achieve the same level of ability to recognizemusical instruments as their normal hearing counterparts. Based on theadult testing, however, chronic use of FSP may improve overall auditoryperformance with musical instrument identification. Chronic use of FSPmay therefore promote or maintain important central auditory processesfor complex sound perception. This may have greater implications for thepediatric population who use such processing strategies during criticalperiods in auditory development. O 044SOUND CATERPILLAR - ASSESSMENT AND TRAINING OFSOUND AND MUSIC PERCEPTION SKILLS IN HEARINGIMPAIRED CHILDRENL. De Bruyn, B. Philips, D. Moelants, P. Coussement, M. Leman, I. DhoogeGhent University, Musicology, GENT, BelgiumE-MAIL: leen.debruyn@ugent.beOBJECTIVESWe assessed and compared the development of timbre and melody dis-crimination and representation skills in prelingually deaf children usingcochlear implants (CI), in severe hearing-impaired children using hearingaids (HA) and in normal-hearing children (NH). METHODS 36 CI children, 36 HA children and 136 NH children, divided in three agecategories (6-8 yo, 9-10 yo, 11-12 yo), were asked to perform timbre andmelody discrimination and representation tasks in the framework of a so-cial, interactive sound game - Sound Caterpillar - developed as an assess-ment battery within the scope of this research project. RESULTS Results show no significant differences between NH, HA and CI for timbrediscrimination and show a clear development of timbre discriminationabilities with age regardless of the hearing impairment or aid. For melodydiscrimination we find a strong development in older NH-children,whereas this improvement is not established in HA and CI children. More-over, both HA and CI children do not succeed in obtaining better thanchance scores for melody discrimination up to the age of 12. Concerningsound representation, HA and CI children focus much more on aspects ofsound quality to represent sounds, whereas NH-children rely on soundidentification or association. CONCLUSIONS We established and compared developmental curves for timbre andmelody discrimination in CI, HA and NH children. These results are nowused to further develop the social sound game Sound Caterpillar into a re-search-based and age-appropriate auditory training tool for severe hearingimpaired children.
