| Research Abstract |
We performed brain activation test using FDG-PET and cognitive neuropsychological test using McGurk effect to evaluate auditory or visual predominance during language acquisition in profoundly deafened children. The brain activation study with speech reading task revealed strong activation in the frontal cortex, parietal cortex, superior and middle temporal gyri and occipital visual cortex. The cognitive test using McGurk effect revealed stronger visual influence on cochlear implant children compared to normal hearing controls in audio-visual integration. It has been found that children using cochlear implants, even those with high speech perception skills, may acquire spoken language utilizing some visual cues in daily life.
