Emotional valence and arousal induced by auditory stimuli among individuals with visual impairment

Despite significant vision loss, humans can still recognize various emotional stimuli via a sense of hearing and express diverse emotional responses, which can be sorted into two dimensions, arousal and valence. Yet, many research studies have been focusing on sighted people, leading to lack of knowledge about emotion perception mechanisms of people with visual impairment. This study aims at advancing knowledge of the degree to which people with visual impairment perceive various emotions - high/low arousal and positive/negative emotions. A total of 30 individuals with visual impairment participated in interviews where they listened to stories of people who became visually impaired, encountered and overcame various challenges, and they were instructed to share their emotions. Participants perceived different kinds and intensities of emotions, depending on their demographic variables such as living alone, loneliness, onset of visual impairment, visual acuity, race/ethnicity, and employment status. The advanced knowledge of emotion perceptions in people with visual impairment is anticipated to contribute toward better designing social supports that can adequately accommodate those with visual impairment.
