Figure 2From: Individual differences in non-symbolic numerical abilities predict mathematical achievements but contradict ATOMCorrelations (accuracy) between non-symbolic magnitude estimation and symbolic numerical abilities (mental calculation). A positive correlation was found between numerical discrimination (both within and outside the subitizing range) and mental calculation. Data of non-symbolic estimation of time, space and number (ANS) refer to the five highest ratios in this and in the following figure.Back to article page
