A Working Memory Account for Spatial-Numerical Associations
van Dijck, Jean-Philippe; Fias, Wim
Cognition, v119 n1 p114-119 Apr 2011
Several psychophysical and neuropsychological investigations have suggested that the mental representation of numbers takes the form of a number line along which magnitude is positioned in ascending order according to our reading habits. A longstanding debate is whether this spatial frame is triggered automatically as intrinsic part of the number semantics or whether it constitutes a short-term representation constructed during task execution. Although several observations clearly favor the working memory account, its causal involvement has not yet been demonstrated. In two experiments we show that information stored in working memory get spatially coded in function of its ordinal position in the sequence and that the spatial-numerical associations typically observed in number categorization tasks draw upon this mechanism. (Contains 3 figures.)
