The 15 articles in this special issue on The Representation of Concepts illustrate the rich
variety of theoretical positions and supporting research that characterize the area. Although …

In this study, we ran a meta-analysis of neuroimaging studies to pinpoint the neural regions
that are commonly activated across space, time, and numerosity, and we tested the …

There has long been interest in how the mind represents numerical magnitude, particularly
in the absence of symbols. For humans and nonhuman animals, number represents a core …

Humans and other species have perceptual mechanisms dedicated to estimating
approximate quantity: a sense of number. Here we show a clear interaction between self …

As perception of time is fundamental for action planning and execution, we investigated how
action distorts the perception of visual duration. Participants adapted to tap** in midair for …

Processing quantities such as the number of objects in a set, size, spatial arrangement and
time is an essential means of structuring the external world and preparing for action. The …

Multiple tasks have been used to demonstrate the relation between numbers and space.
The classic interpretation of these directional spatial–numerical associations (d-SNAs) is …

How numerical quantity is processed is a central issue for cognition. On the one hand the
“number sense theory” claims that numerosity is perceived directly, and may represent an …

Visual numerosity is represented automatically and rapidly, but much remains unknown
about the computations underlying this perceptual experience. For example, it is unclear …

A common cognitive process in everyday life consists in the comparative judgements of
emotions given a pair of facial expressions and the choice of the most positive/negative …
