Frequency-based Dissociation of Symbolic and Nonsymbolic Numerical Processing during Numerical Comparison

Multi-Representation of Symbolic and Nonsymbolic Numerical Magnitude in Chinese Number Processing

Numerical information can be conveyed by either symbolic or nonsymbolic representation. Some symbolic numerals can also be identified as nonsymbolic quantities defined by the number of lines (e.g., I, II, III in Roman and -, =, ≡ in Japanese Kanji and Chinese). Here we report that such multi-representation of magnitude can facilitate the processing of these numerals under certain circumstances....

Symbolic and Nonsymbolic Pathways of Number Processing

Recent years have witnessed an enormous increase in behavioral and neuroimaging studies of numerical cognition. Particular interest has been devoted toward unraveling properties of the representational medium (mental number line) on which numbers are thought to be represented. We have argued that a correct inference concerning these properties requires distinguishing between different input mod...

Common and segregated neural pathways for the processing of symbolic and nonsymbolic numerical magnitude: An fMRI study

Numbers are everywhere in modern life. Looking out a window, one might see both symbolic numbers, like the numerals on a thermometer, and nonsymbolic quantities, such as the number of chickadees at a bird feeder. Although differences between symbolic and nonsymbolic numbers appear very salient, most research on numerical cognition has focused on similarities rather than differences between nume...

Basic mechanisms of numerical processing: cross-modal number comparisons and symbolic versus nonsymbolic numerosity in the intraparietal sulcus.
