The concept of number has traditionally been considered as a prototypical instance of abstract(ed) knowledge. It denotes the size of any arbitrary set of objects, thus seemingly preventing systematic correlations with sensory or motor features. Yet, numerosity does co-vary with physical parameters in perception and action. Importantly, number symbols preserve this association. In this presentation, I describe how number processing obligatorily activates sensory and motor features: both sensory and motor processing are improved in left vs. right space following the presentation of small vs. large numbers. These links are bi-directional and suffice to identify numbers as embodied concepts. Moreover, these space-magnitude associations influence mental arithmetic and everyday quantitative reasoning (cf. Fischer & Shaki, 2014). Implications for research and theorizing will be discussed.
