The Size Congruity Effect Vanishes in Grasping: Implications for the Processing of Numerical Information

Abstract Judgments of the physical size in which a numeral is presented are often affected by the task-irrelevant attribute of its numerical magnitude, the Size Congruity Effect (SCE). The SCE is typically interpreted as a marker of the automatic activation of numerical magnitude. However, a growing...
