Description

In 40 junior high school students wearing a cochlear implant (CI), we conducted a Norm Referenced Test (NRT) of the Japanese language, which is a relative formal academic examination, expressed in 5-grade rating (grade 5 being the best). We examined the relationship between the academic abilities in the Japanese language and the surgical age at CI surgery, period of wearing the CI, the latest hearing threshold with CI and speech discrimination score, operative intelligence (PIQ) and linguistic intelligence (VIQ) evaluated by WISC, and the school type that the child was enrolled in. The rating of ‘2’ in Japanese language academic achievement was the most frequent, in both “reading” and “writing”. There was no significant correlation between the Japanese language ability and the age at CI surgery, period of wearing CI, latest hearing threshold with CI or the speech discrimination score. On the other hand, there were significant correlations between the Japanese language ability and the VIQ and PIQ, and school type. The rating for “reading” was correlated with the PIQ with a correlation coefficient (r) of 0.4, and the VIQ (r=0.6). The rating for “writing” was correlated with the PIQ (r=0.6) and VIQ (r=0.7). The rating for “reading” was correlated with the school type (r=0.50, p<0.01). However, adjustment for the VIQ in partial regression analysis, the relationship between school type and the rating for “writing" could no longer be observed.
