A visual memory and visual discrimination tasks were administered individually on 101 deaf and hearing-impaired children enrolled in kindergartens in Riyadh. Results revealed a relationship between visual discrimination and both visual memory and some demographic variables (gender, age, and type of hearing disability (deaf, and hard of hearing). Our findings also found no gender differences in visual memory and visual discrimination between males and females, in addition no differences were detected in visual memory between deaf and hearing-impaired children. In contrast, our results revealed that there were differences between deaf and hard of hearing children in the visual discrimination task in favor of deaf children, results also showed differences on visual discrimination and visual memory between deaf and hard of hearing children in regards to their age in favor of six-year-old children.
