“…For example, (early and late-onset) blind humans and animals show enhanced auditory target detection (Fieger, Roder, Teder-Salejarvi, Hillyard, & Neville, 2006) and auditory localization (King & Parsons, 1999;Rauschecker & Kniepert, 1994;Voss et al, 2004) on certain tasks. While the effect of partial vision loss on residual senses is less clear, some findings suggest blind individuals with residual vision show changes in non-visual processing too (Cunningham, Weiland, Bao, & Tjan, 2011;Lessard, Pare, Lepore, & Lassonde, 1998).…”

AbstractHuman adults can combine perceptual estimates from different senses to minimize uncertainty, by taking a reliability-weighted average, (the maximum likelihood estimate, MLE). While research has shown that healthy human adults re-weight estimates as their reliability changes from one trial to the next, less is known about how humans adapt to gradual long-term changes in sensory reliability. This study assessed whether individuals diagnosed with progressive visual deterioration, due to retinal disease, combined auditory and visual cues to location according to optimal (MLE) predictions. Twelve patients with central visual loss, 10 patients with peripheral visual loss, and 12 normally sighted adults were asked to localize visual and/or auditory targets in central (1°-18°) and peripheral (36°-53°) locations.Normally sighted adults and patients with peripheral visual loss showed multisensory uncertainty reduction and cue weighting in line with MLE predictions. In contrast, patients with central visual loss did not weight estimates appropriately in either the center or the periphery, and failed to meet MLE predictions in the periphery. Our results show that one visual loss patient group succeeded at optimal cue combination, whilst the other patient group (patients with central vision loss) did not. We propose that sensory remapping due to changes in fixation behavior may contribute to apparent failures in the latter group.

Self-motion direction discrimination in the visually impaired

et al. 2015

Despite the close interrelation between vestibular and visual processing (e.g., vestibulo-ocular reflex), surprisingly little is known about vestibular function in visually impaired people. In this study, we investigated thresholds of passive whole-body motion discrimination (leftward vs. rightward) in nine visually impaired participants and nine age-matched sighted controls. Participants were rotated in yaw, tilted in roll, and translated along the interaural axis at two different frequencies (0.33 and 2 Hz) by means of a motion platform. Superior performance of visually impaired participants was found in the 0.33 Hz roll tilt condition. No differences were observed in the other motion conditions. Roll tilts stimulate the semicircular canals and otoliths simultaneously. The results could thus reflect a specific improvement in canal-otolith integration in the visually impaired and are consistent with the compensatory hypothesis, which implies that the visually impaired are able to compensate the absence of visual input.

Rapid identification of sound direction in blind footballers

auditory stimuli between simple and choice RT tasks. For instance, Kida et al. (2005) reported that baseball experts had shorter RTs than tennis players and nonathletes in a Go/Nogo RT task but not in a simple RT task. Blind individuals also showed superior auditory choice RTs compared with sighted individuals in a divided attention task (Kujala et al. 1997) and a spatial attention task (Chen et al. 2006). Moreover, early-blind individuals had shorter RTs than sighted individuals in selective attention tasks, but not in a simple RT task, indicating enhanced attentional performance in early-blind individuals (Collignon and De Volder, 2009; Collignon et al. 2006). Based on previous studies, it was assumed that blind footballers with visual impairments would have shorter auditory choice RTs than sighted nonathletes. Given the superiority of blind footballers in choice RT tasks, it should be determined whether their shorter choice RTs are due to rapid identification of sound direction or faster processing of auditory input and motor output. However, it remains unknown whether blind footballers have shorter auditory simple RTs and choice RTs than sighted athletes, who are required to produce a faster response largely in the visual modality. Taken together, the present study aimed to compare simple RT, choice RT, and response accuracy among blind footballers, sighted footballers, and nonathletes. We hypothesized that blind footballers would have shorter RTs than sighted footballers in the choice RT tasks, but not in the simple RT task. We also hypothesized that blind footballers would show higher overall response accuracy and less front-back confusion. Methods Participants Participants were blind footballers (n = 10; mean age = 27.6 ± 5.3 years; playing experience = 8.0 ± 4.2 years), sighted college footballers (n = 11; mean age = 19.2 ± 1.2 years; playing experience = 12.4 ± 2.2 years), and healthy sighted nonathletes (n = 11; mean age = 22.7 ± 2.9 years; no regular exercise or training), based on the experimental design of the previous study (Campayo-Pierna et al. 2017). The sample size was based on an a priori power analysis for the within-between interaction in a repeated measures ANOVA (estimated effect size of f = .25, α =.
