Previous cross-sectional research has shown that prelingually deaf children who use cochlear implants (CIs) show enhancement when speech is presented in an audiovisual (AV) format compared to auditory-alone (A-alone) and visual-alone (V-alone) formats. The purpose of the present study was to investigate the development of AV integration skills in this clinical population. We examined the AV sentence comprehension skills of a large group of prelingually deaf children with CIs longitudinally, from pre-implantation to 5 years post-implantation. The children were asked to repeat everyday sentences under three presentation conditions: A-alone, V-alone, and AV. Overall, the results revealed that these children performed better in the AV condition than in the A-alone and V-alone conditions. Performance improved over time after cochlear implantation only for A-alone and AV conditions. Finally, measures of AV sentence comprehension were strongly correlated with other clinical outcome measures of speech perception, speech production, and language processing.
