Representations of Symbolic Fractions and Nonsymbolic Ratios

One special property of the magnitudes of symbolic fractions and nonsymbolic ratios is that their magnitudes are determined relationally. They offer new potential insights into the nature of human numerical and mathematical cognition. One study demonstrated the Spatial-Numerical Association of Response Codes (SNARC) effect with nonsymbolic ratios. Another study investigated number line estimation patterns of symbolic fractions and nonsymbolic ratios from aspects of percent absolute error (PAE), psychophysical functions, and bias pattern.
