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

Dyscalculia, a specific learning disability that impacts arithmetical skills, has previously been
associated to a deficit in the precision of the system that estimates the approximate number …

The number of elements distributed in a three-dimensional stimulus is overestimated
compared to a two-dimensional stimulus when both stimuli have the same number of …

Advances in opto-electronics enable replacement of conventional submarine periscopes
which display only a portion of the horizon (low field of view), with digital periscopes, which …

In conflict with historically dominant models of time perception, recent evidence suggests
that the encoding of our environment's temporal properties may not require a separate class …

Research has shown that body size judgements are frequently biased, or inaccurate.
Critically, judgement biases are further exaggerated for individuals with eating disorders, a …

Observers' numerosity judgments in binocular stereopsis were examined in four
experiments, using random-dot stereograms (RDSs) that depicted a two-dimensional (2-D) …

A series of studies show interest in how visual attributes affect the estimate of object
numbers in a scene. In comparison tasks, it is suggested that larger patches are perceived …

The number of elements in two stereo-surfaces parallelly overlapped in depth is
overestimated compared to that in a single flat surface, even when both have the same …

Simultaneous density contrast, or SDC, is the phenomenon in which the perceived density of
a textured region is altered by a surround of different density (Mackay, 1973). SDC provides …
