Perks of blindness: Enhanced verbal memory span in blind over sighted adults

Captar y procesar un mensaje auditivo ultrarrápido en personas con ceguera total

“…Debido a estas conexiones neuronales, así como a un aparente mejor rendimiento de las personas ciegas tempranas en tareas de lenguaje y memoria de trabajo (Arcos, Harhen et al, 2022;Arcos, Jaeggi et al, 2022), las investigaciones sobre esta población han ido aumentando.…”

“…A pesar de que aún hay controversia en los datos, se ha podido observar en diferentes estudios, tal y como se mencionaba al principio, cómo la edad a la que se diagnosticó la ceguera y el tiempo que lleve la persona sin ver son esenciales para predecir un mejor rendimiento en tareas de memoria de trabajo y lenguaje (Arcos, Harhen et al, 2022;Arcos, Jaeggi et al, 2022).…”

Development of Trisensory Backward Digit Span in Terms of Ages

“…There are a number of studies that were conducted with unisensory (employing one sensory organ [e.g., visual or auditory] to learn something) or bisensory presentation (employing 10.54392/ajir2345 two sensory organs) of BDS tasks. These studies with BDS tasks were administered focusing on different variables related to human lives (e.g., effects of age (e.g., Gregoire & Linden, 1997;Füllgrabe & Öztürk, 2022), education and culture (e.g., Ostrosky-Solis & Lozano, 2006) on BDS tasks; attention problems and executive functioning in children (Rosenthal, Riccio, Gsanger, & Jarratt, 2006) effects of noise/sound & tactile on BDS (Osman & Sullivan, 2015;Arcos, Jaeggi & Grossman, 2022) cognitive strategies employed in BDS (e.g., Hilbert, Nakagawa, Puci, Zech & Buhner, 2015). Hester, Kinsella and Ong (2004) studied forward and backward digit span performances of the subjects aged between 16-89 in which they verbally (unisensory) presented the subjects with an increasingly longer series of digits (span 2-9) in forward condition.…”

“…His studies revealed that BDS measured working memory in children and short-term memory (that holds but does not manipulate a small amount of information in the active or readily available state for a short period of time typically 10 or 15 seconds or sometimes up to a minute) in adults. Recently, Arcos et al, (2022) examined verbal memory span in 77 participants (sighted-58 & blind-19) with verbal short-term memory span tasks and forward and backward digit span tasks involving auditory, visual or tactile modalities. Their studies found that blind individuals performed better on verbal short-term memory span tasks than sighted individuals.…”

“…In addition, blind individuals showed good performances in both auditory forward and backward digit span tasks. A few studies investigated working memory in the tactile modality (e.g., Papagno, Comi, Riva, Bizzi, Vernice, Casarotti, Fava & Bello, 2017;Arcos et al, 2022). Hence, it is observed that most of the research focusing on backward digit span was based on either unisensory modality (e.g., auditory or visual or tactile) or bisensory (auditory and visual) modalities or both.…”
