This study investigated prosodic perception and musical pitch discrimination in adults using cochlear implants (CI), and examined the relationship between prosody perception scores and non-linguistic auditory measures, demographic variables, and speech recognition scores.
Participants were given four subtests of the PEPS-C (profiling elements of prosody in speech-communication), the adult paralanguage subtest of the DANVA 2 (diagnostic analysis of non verbal accuracy 2), and the contour and interval subtests of the MBEA (Montreal battery of evaluation of amusia).
Twelve CI users aged 25;5 to 78;0 years participated.
CI participants performed significantly more poorly than normative values for New Zealand adults for PEPS-C turn-end, affect, and contrastive stress reception subtests, but were not different from the norm for the chunking reception subtest. Performance on the DANVA 2 adult paralanguage subtest was lower than the normative mean reported by Saindon (2010) . Most of the CI participants performed at chance level on both MBEA subtests.
CI users have difficulty perceiving prosodic information accurately. Difficulty in understanding different aspects of prosody and music may be associated with reduced pitch perception ability.
本研究调查了使用人工耳蜗（CI）的成年人的韵律感知和音高辨别能力，并检验了韵律感知分数与非语言听觉测量、人口统计学变量及言语识别分数之间的关系。
参与者接受了四项PEPS-C（言语交流中韵律的剖析要素）子测试、DANVA 2（非言语准确性诊断分析2）的成人副语言子测试以及MBEA（蒙特利尔失乐感评估量表）的轮廓和音程子测试。
12名年龄在25岁5个月至78岁0个月的人工耳蜗使用者参与了研究。
人工耳蜗使用者在PEPS-C的句末、情感和对比重音接收子测试中的表现显著低于新西兰成年人的常模值，但在组块接收子测试中的表现与常模无异。DANVA 2成人副语言子测试的表现低于Saindon（2010年）报告的常模均值。大多数人工耳蜗使用者在MBEA的两项子测试中的表现均为随机水平。
人工耳蜗使用者在准确感知韵律信息方面存在困难。理解韵律和音乐不同方面的困难可能与音高感知能力下降有关。
