A comparative study on the visual color perception of hearing and deaf people

Abstract

This research presents a fundamental tool and approach for accessible design in terms of color categories in hearing and deaf people. Participants were 12 deaf girls aged 11 to 26 from Bangkok's Setsatian School for the Deaf and 15 hearing girls aged 11 to 15 from Kasetsart University's Laboratory School Center for Educational Research and Development. A comparison of total error score (TES) revealed no significant difference between deaf and hearing people in terms of color perception. The findings support the general hypothesis that there are more similarities than differences in color perception between these two groups; thus, confirming the contribution of deaf culture to the social environment of the hearing community as a whole.
