The present study was conducted to examine the relationship between the hearing ability and the results of evaluation by WISC-IV in 12 children wearing hearing aids. Assessment of the children's hearing ability was conducted by pure-tone audiometry, sound-field threshold measurements, speech recognition tests, speech discrimination tests, and speech discrimination tests in noise. We found no correlation between either the Verbal Comprehension Index (VCI) or the Perceptional Reasoning Index (PRI) and the hearing ability in any of the 12 children. There were significant differences between the VCI scores and PRI in five children, in all of whom the VCI was significantly lower than the PRI. Although the results showed that language acquisition had not progressed to the same extent as their perceptual ability, the VCI scores exceeded the lower limit of the average in all cases.
