Calibrating the mental number line.
Human adults are thought to possess two dissociable systems to represent numbers: an approximate quantity system akin to a mental number line, and a verbal system capable of representing numbers exactly. Here, we study the interface between these two systems using an estimation task. Observers were asked to estimate the approximate numerosity of dot arrays. We show that, in the absence of calib...

متن کاملExperiential Origins of the Mental Number Line
People map numbers onto horizontal space, forming an implicit mental number line (MNL). The direction of the MNL, which varies across cultures, has often been attributed to the direction of reading and writing words. Yet, this proposal is neither clearly motivated nor well supported by experimental data. Here we tested the hypothesis that fingercounting habits can determine the direction of the...
متن کاملThe mental number line and the human angular gyrus.
To investigate the hemispheric organization of a language-independent spatial representation of number magnitude in the human brain we applied focal repetitive transcranial magnetic stimulation (rTMS) to the right or left angular gyrus while subjects performed a number comparison task with numbers between 31 and 99. Repetitive TMS over the angular gyrus disrupted performance of a visuospatial s...
متن کاملBisecting the mental number line in near and far space.
Much evidence suggests that common posterior parietal mechanisms underlie the orientation of attention in physical space and along the mental number line. For example, the small leftward bias (pseudoneglect) found in paper-and-pencil line bisection is also found when participants "bisect" number pairs, estimating (without calculating) the number midway between two others. For bisection of physi...
