A Study on the Structure of Intelligence of the Hearing Impaired Students Author: Bey-Lih Chung

Abstract：

The purpose of this study was to understand the structure of intelligence of the hearing im-paired students. The subjects, 150 students, were randomly selected from 11, 13, and 15 year-old students of Taipei Municipal School for the Deaf. Each group had 25 male and 25 female students.
All subjects were tested by the Wechsler Intelligence Scale for Children, Performance Test (WISC-P) individually.
The data obtained were statistically treated by two way ANOVA, Scheffe method for multiple comparison, and they were drawn as the profile of the structure of intelligence.
The main findings of this study were as follows:
1. There was significant difference between age-11 and age-13 group students in IQ increasing.
2. There was significant difference between the male and female students' IQ of 15 year-old group.
3. The mean IQ of these hearing impaired students was 83.04.
4. These hearing impaired students were inferior to normal hearing students on all the mental functions of WISC-P test.
5. Comparison with hearing impaired students themselves, the mental functions of visual-motor coordination and perceptual organization abilities were superior. But the mental functions of abilities to differentiate essential from nonessential detail, concentration, reasoning, spatial visualization, abstract conceptualizing ability, analysis and synthesis were inferior.
