Hearing Aid Use is Associated with Faster Visual Lexical Decision.

This study investigates the impact of hearing aid (HA) use on visual lexical decision (LD) performance in individuals with hearing loss. We hypothesize that HA use benefits phonological processing and leads to faster and more accurate visual LD. We compared the visual LD performance among three groups: 92 short-term HA users (<5 years), 98 long-term HA users, and 55 nonusers, while controlling for hearing level, age, and years of education. Results showed that, compared with non-HA users, HA users showed significantly faster reaction times in visual LD, specifically, long-term HA use was associated with smaller difference in reaction time for pseudowords compared to nonwords. These results suggest that HA use is associated with faster visual word recognition, potentially reflecting enhanced cognitive functions beyond auditory processing. These findings point to possible cognitive advantages linked to HA use.
