Abstract
The purposes of this study were (a) to evaluate the Primary Measures of Music Audiation (PMMA) as a test of musical perception for postligually deafened adult cochlear implant (CI) users; and (b) to report test outcome on the Rhythm and Tonal subtests of the PMMA. Correlations between PMMA scores and speech perception tasks were calculated. Subjects were 34 postlingually deafened adults with CI experience. Subject performance on the PMMA was analyzed to determine test usability and technical adequacy (reliability, item discrimination, and difficulty) for this particular population. Comparisons were made across two different implant types (Nucleus and Ineraid devices) and across Rhythm and Tonal subtests. The PMMA was found to be usable with minor adjustments. No significant differences in accuracy were found for the Rhythm or Tonal subtest across devices. However, CI (Nucleus and Ineraid) users were significantly more accurate on the Rhythm than the Tonal subtest (p ≤ .001). The mean difficulty for the Rhythm subtest was 84.93, while the mean difficulty for the Tonal subtest was 77.50. The mean discrimination indices were as follows: Rhythm subtest, .18; Tonal subtest, .28. The Tonal subtest contained a larger number of items within the satisfactory range for item difficulty and item discrimination. The strongest correlations between musical perception and speech perception were between the Tonal subtest and the speech perception measures of phoneme identification (r = .45) and accent recognition (r = .46).
