Deaf children were tested by means of PVT (Picture Vocabulary Test) and WIPPSI or WISC-R, then the relation between speech development and hearing level was discussed. The age of 22 children at the test ranged from 4 years to 13 years. Their average hearing level ranged from 37 dB to 71 dB. Their PIQ (performed IQ) was within the normal range. Results of PVT were almost related to that of VIQ (Verbal IQ), but there was no evident relation between the results of PVT or VIQ and hearing level. Some of the children with mild hearing impairment showed poorer development of their vocabulary and verbalism than expected. We considered that the development of vocabulary and verbalism was affected by several factors besides their hearing level.
