There is debate in the numerical cognition literature concerning symbolic and nonsymbolic number representation systems as foundations for more complex mathematical skills. The purpose of this study was to investigate the relation between these number representation systems and calculation fluency. The present study used 51 university students. Participants(More)
Both subitizing, the ability to enumerate small sets without counting, and finger gnosis, the ability to mentally represent one’s fingers, have been found to predict calculation skill in children (Penner-Wilger et al., 2007, 2009). In the current paper, we examined whether these same relations hold for young adults. Consistent with the developmental data,(More)
Finger gnosis and magnitude comparison were examined as predictors of adult numeracy. Previous findings were extended by (1) controlling for domain-general comparison processes (using a luminance judgment task), (2) controlling for visuo-spatial memory, and (3) examining the robustness of the relations across different numeracy tests, including exact and(More)
The present study investigated the diverse cognitive profiles of children learning mathematics in early elementary school. Unlike other types of learning difficulties, mathematics impairments are not characterized by a single underlying cognitive deficit, instead multiple general and numeracyspecific cognitive skills have been proposed to underlie(More)
