RT Journal Article T1 Nonsymbolic Comparison in Deaf Students: No Evidence for a Deficit in Numerosity Processing. A1 Rodríguez-Santos, José Miguel A1 García-Orza, Javier A1 Calleja-Reina, Marina A1 Damas, Jesús A1 Iza-Miqueleiz, Mauricio K1 Sordos - Educación K1 Matemáticas - Estudio y enseñanza AB It is commonly found that deaf and hard of hearing (DHH) students experience delayed mathematical achievement. The present study used two nonsymbolic comparison tasks to explore the basic numerical skills of DHH students. Nine prelocutive DHH students with cochlear implants and nine hearing students, matched on nonverbal IQ, visual short-term memory, and verbal comprehension, were recruited. The participants performed two different collection comparison tasks with different ratios and under different perceptual conditions. Analyses by task showed similar response times, accuracy, and ratio effects for both groups on the Low Perceptual Condition task, a finding suggesting that the two groups accessed similar representations of quantity. Differences in performance on the simpler High Perceptual Condition task, on which the DHH group showed slower response times, probably were strategic in origin. The results suggest that DHH students have no deficits in basic numerical skills PB Gallaudet University Press YR 2018 FD 2018-08-11 LK https://hdl.handle.net/10630/30360 UL https://hdl.handle.net/10630/30360 LA eng NO Rodríguez-Santos, J.
