“…In this study, participants’ left‐hand responses were faster when they judged parity of smaller numbers (e.g., 1 or 2) while right‐hand responses were faster for larger numbers (e.g., 8 or 9), suggesting that accessed number representations are arranged along a Mental Number Line (MNL) with numerical magnitude monotonically increasing from left to right. Numerous studies that followed demonstrated an intimate link between SNARC and visual attention, by showing that SNARC‐related processing differences result from attentional displacement (Fischer, Castel, Dodd, & Pratt, ; Fischer, Warlop, Hill, & Fias, ; Myachykov, Chapman, & Fischer, ) and by documenting neuroanatomical links between oculomotor control and mental arithmetic (Knops, Thirion, Hubbard, Michel, & Dehaene, ). Furthermore, SNARC was validated in studies that employed numerous tasks, with different effectors, including hand, foot, eye, and head movements, and in different modalities, suggesting that it reflects a relatively universal, task‐independent, and supra‐modal representation of numerical magnitude.…”
