Effects of longstanding degraded auditory signal on visuospatial, visuomotor, and visual attention skills in adults with hearing loss

Research of visual attention networks in deaf individuals: a systematic review

“…This aligns with previous research on typical hearing children using the same task, which showed a specific development ceiling at 10 years old (Betts et al, 2006). However, it appears that deaf individuals do not reach the levels observed in typical hearing adults, at least those who are not native signers (Bharadwaj et al, 2020).…”

“…In adults, there are no studies on tonic alertness involving deaf signers without CI. However, age at CI implantation does not seem to have an impact on CPT performance (Kronenberger et al, 2013;Bharadwaj et al, 2020). While no differences were observed between deaf signers without CI and full hearing children (Dye and Hauser, 2014), differences have been found in oral-speaking deaf children with CI (Yucel and Derim, 2008;Hoffman et al, 2018).…”

“…We note that all studies involving adults employed a cross-sectional design (see Figure 2). The two studies that measured tonic alerting in deaf adults revealed poorer performance compared to hearing peers when using CPTs as a measure (Kronenberger et al, 2013;Bharadwaj et al, 2020). Specifically, Kronenberger et al (2013) The only study that measured phasic alerting with alerting cues found an advantage in deaf adults (Prasad et al, 2022).…”

“…Among these studies, five exclusively involved children aged between 6 and 12 years, two studies focused on adults aged between 19 and 57, and one study used a mixed sample of adults and children aged between 7 and 25. Except for two of the 11 studies (Daza and Phillips-Silver, 2013;Bharadwaj et al, 2020), the rest compared the deaf group with their hearing peers. Six of the 11 studied the tonic alerting network using CPTs, while one studied phasic alerting using the ANT (see Table 3).…”

“…Regarding our secondary objective, to explore any differences observed among deaf individuals in relation to variables concerning hearing loss history, device use and mode of communication, very few studies examined adults with CI (see Table 4), possibly due to the relative novelty of the technology (Wilson and Dorman, 2008). The few studies that included adults with CI did not find any effect of implantation in tonic alerting (Kronenberger et al, 2013;Bharadwaj et al, 2020). The rest of the findings will be discussed below along with the results of studies in children.…”
