Abstract: | A cornerstone of contemporary research in numerical cognition is the surprising link found between numbers and space. In particular,
people react faster and more accurately to small numbers with a left-hand key and to large numbers with a right-hand key.
Because this contingency is found in a variety of tasks, it has been taken to support the automatic activation of magnitude
as well as the notion of a mental number line arranged from left to right. The present study challenges the presence of a
link between left-right location, on the one hand, and small-large number, on the other hand. We show that a link exists between
space and relative magnitude, a relationship that might or might not be unique to numbers. |
