AB  - OBJECTIVE: The primary purpose of the current study was to evaluate early 
      prelingual auditory development (EPLAD) and early speech perception 
      longitudinally over the first year after cochlear implantation in 
      Mandarin-speaking pediatric cochlear implant (CI) recipients. Outcome measures 
      were designed to allow comparisons of outcomes with those of English-speaking 
      pediatric CI recipients reported in previous research. METHOD: A hierarchical 
      outcome assessment battery designed to measure EPLAD and early speech perception 
      was used to evaluate 39 pediatric CI recipients implanted between the ages of 1 
      and 6 years at baseline and 3, 6, and 12 months after implantation. The battery 
      consists of the Mandarin Infant-Toddler Meaningful Auditory Integration Scale 
      (ITMAIS), the Mandarin Early Speech Perception (MESP) test, and the Mandarin 
      Pediatric Speech Intelligibility (MPSI) test. The effects of age at implantation, 
      duration of pre-implant hearing aid use, and Mandarin dialect exposure on 
      performance were evaluated. EPLAD results were compared with the normal 
      developmental trajectory and with results for English-speaking pediatric CI 
      recipients. MESP and MPSI measures of early speech perception were compared with 
      results for English-speaking recipients obtained with comparable measures. 
      RESULTS: EPLAD, as measured with the ITMAIS/MAIS, was comparable in Mandarin- and 
      English-speaking pediatric CI recipients. Both groups exceeded the normal 
      developmental trajectory when hearing age in CI recipients and chronological age 
      in normal were equated. Evidence of significant EPLAD during pre-implant hearing 
      aid use was observed; although at a more gradual rate than after implantation. 
      Early development of speech perception, as measures with the MESP and MPSI tests, 
      was also comparable for Mandarin- and English-speaking CI recipients throughout 
      the first 12 months after implantation. Both Mandarin dialect exposure and the 
      duration of pre-implant hearing aid use significantly affected measures of early 
      speech perception during this time period. CONCLUSIONS: EPLAD and early speech 
      perception exhibited similar patterns of improvement during the first 12 months 
      after early cochlear implantation. The duration of pre-implant hearing aid use 
      had a significant positive effect on both categories of outcome measures. 
      Consistent post-implant EPLAD trajectories and early speech perception results 
      provide objective evidence that can guide best practices in early intervention 
      protocols.
