| Abstract: | Many children with hearing loss (CHL) show a delay in mathematical achievement compared to childrenwith normal hearing (CNH).This study examinedwhether there are differences in acuity of the approximate number system (ANS) betweenCHL andCNH, and whetherANS acuity is related to math achievement.Working memory (WM), short-termmemory (STM), and inhibition were considered as mediators of any relationship between ANS acuity and math achievement. Seventy-five CHL were compared with 75 age- and gender-matched CNH. ANS acuity, mathematical reasoning,WM, and STM of CHL were significantly poorer compared to CNH. Group differences in math ability were no longer significant when ANS acuity,WM, or STMwas controlled. For CNH,WMand STMf ully mediated the relationship ofANS acuity tomath ability; forCHL,WMand STMonly partiallymediated this relationship. ANS acuity, WM, and STM are significant contributors to hearing status differences in math achievement, and to individual differences within the group of CHL. [ABSTRACT FROM AUTHOR] |
