Abstract
The Tsumori and Inage Developmental Questionnaire Test was performed on 62 hearing impaired infants ranging age from 1 year 1 month to 3 years 4 months. Their averaged hearing level after 2 years of age measured by COR, ABR, and the peep show ranged from 55dB to 105dB.Average developmental quotient in five aspects such as motor, inquiry and operation, sociability, habits of daily life and language and speech in this test was 102. 7, 90.6, 73.8, 91.1, 58.0 respectively. The profile of hearing impaired infants was more retarded in two of the five aspects; sociability and language and speech.Hearing impaired infants could not perform 15% of the test items such as “pointing to eyes, ears, mouth, or nose by himself”.It is concluded that the profile obtained from the Tsumori-test is effective for screening hearing impaired infants from normal infants.
