Bisecting 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...

متن کاملThe middle house or the middle floor: Bisecting horizontal and vertical mental number lines in neglect
This study explores the processing of mental number lines and physical lines in five patients with left unilateral neglect. Three tasks were used: mental number bisection ('report the middle number between two numbers'), physical line bisection ('mark the middle of a line'), and a landmark task ('is the mark on the line to the left/right or higher/lower than the middle of the line?'). We manipu...
متن کاملCommentary on: “Number-space mapping in the newborn chick resembles humans' mental number line”
concepts of “less” and “more,” it would be more efficient to re-use the system already in place for processing space (Holmes and Lourenco, 2011). Considering numerical processing as an exaptation (Gould and Vrba, 1982) of spatial processing could explain the functional link between these two systems. An important caveat to these hypotheses is that one-to-one homologies between avian and mammali...
متن کاملCalibrating 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...
