Numerical representations: Abstract or supramodal? Some may be spatial

摘要

The target article undermines the existence of a shared unitary numerical format, illustrating a variety of representations. The "abstract"/ "not-abstract" dichotomy does not capture their specific features. These representations are "supramodal" with respect to the sensory modality of the stimulus, and independent of its specific notation, with a main role of spatial codes, both related and unrelated to the mental number line.
