Comparison of visual working memory in deaf and hearingimpaired students with normal counterparts: A research in people without sign language


Background and Aim: The hearing defects in deaf and hearing-impaired students also affect their cognitive skills such as memory in addition to communication skills. Hence, the aim of this study was to compare visual working memory in deaf and hearing-impaired students with that in normal counterparts.
Method: In the present study, which was a causal-comparative study using the André Rey test, 30 deaf and 30 hearing-impaired students were compared with 30 students in a normal group, and they were matched based on gender, intelligence, educational grade, and socioeconomic status.
Findings: Findings show that there is significant difference between the three groups’ subjects
(p<0.05). The average of the normal group was more than that of the other two groups. However, the difference between the two auditory impaired groups was not significant (p>0.05).
Conclusion: Function of deaf or hard-of-hearing students in the visual working memory task was weaker in comparison with the normal counterparts, while the two deaf and hard-of-hearing groups have similar functions. With a better identification and understanding of the factors that affect the development of this cognitive ability, we can offer new methods of teaching and reduce many of the disadvantages of this group of people in the different fields of cognitive science.
