Attention mediates the influence of numerical magnitude on temporal processing

Abstract The processing of time and numbers has been fundamental to human cognition. One of the prominent theories of magnitude processing, a theory of magnitude (ATOM), suggests that a generalized magnitude system processes space, time, and numbers; thereby, the magnitude dimensions could potential...

description	Abstract The processing of time and numbers has been fundamental to human cognition.
