Introduction: Deafness can be considered as partial or total hearing loss that makes it impossible to receive or process sound stimuli, and cause changes in other sensory systems, such as the visual system. Objective: This study evaluated whether hearing deprivation alters the color perception discrimination of young adults and Brazilian Sign Language (Libras) interpreters. Method: Thirty young adults of both sexes participated in this research. Deaf participants were diagnosed with severe or profound bilateral sensorineural hearing loss, and all volunteers had normal 20/20 visual acuity. We were used the Mini-Mental State Examination and the Lanthony Desaturated D-15 as instruments. Results: A significant difference was found for the color confusion index (CCI) (χ 2 (2) = 12.14; p = .02) and in randomness (χ 2 (2) = 9.79; p = .007). Deaf individuals showed greater losses in the C-index when compared to listeners (U = 11.85; p = .003) and interpreters (U = 11.85; p = .008). Conclusion: Our study shows that deafness causes losses in color discrimination, with specific losses in the spatial arrangement and CCI. Public Significance StatementThis study describes at sensory threshold levels the visual capacity that deaf subjects must discriminate color perception.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
