Abstract

This study aimed to investigate the psychometric characteristics of the Wechsler-4 scale of the intelligence of deaf people with Waardenburg syndrome and the level of intelligence according to the mental state. To achieve the objectives of the study, a descriptive survey method was used. The sample of the study consisted of (17) students from all deaf schools in Jordan, whose ages ranged between (8-17) years, and (WISC-IV) was applied in sign language. Indicators are reached for Construct Validity (2.741 - 0.243). And indications for reliability, where the correlation coefficients ranged between (0.487 - 0.898). The results showed that there were no differences in the IQ level of deaf people with Waardenburg syndrome due to gender. The absence of differences in the IQ level of deaf people with Waardenburg syndrome is due to the mental state variable in favor of the deaf group of those with the borderline between Gifted and Superior, but the overall IQ level of the deaf person with Waardenburg syndrome is within the lower limits (IQ = 71), which is Learning Disability. There are also differences in the level of the sub-tests of the scale for deaf people with Waardenburg syndrome, as the (Cancellation) test was the highest score and then (coding) in second place. The study recommends including this syndrome as part of the hearing impairment categories. Studies have been carried out on the development of the functional section of the Wechsler-4 scale to suit the visual perception of deaf people with Waardenburg syndrome.
