Although humans are the only species to possess language-driven abstract mathematical
capacities, we share with many other animals a nonverbal capacity for estimating quantities …

Novel results elucidating the magnitude, binocularity and retinotopicity of aftereffects of
visual texture density adaptation are reported as is a new contingent aftereffect of texture …

Burr and Ross [1] have recently proposed that the visual dimension of number is itself
directly adaptable. The aftereffect they describe is one that my colleagues and I previously …

The visual system rapidly represents the mean size of sets of objects (Ariely, 2001). Here,
we investigated whether mean size is explicitly encoded by the visual system, along a single …

Previous studies have shown that adaptation to asinusoidal grating raises the contrast
threshold for detecting gratings of similar spatial frequency and causes a shift in the …

Reviews the 1974–1977 visual perception literature and discusses the state of the art in the
following 3 areas:(a) the 3-dimensionality of perception,(b) the perception of pictures and flat …

An object is perceived as larger when it is surrounded by smaller context objects than when
it is surrounded by larger context objects. The origin of this well-known phenomenon, called …

The brain is peculiarly difficult to study because it is a closely coupled, rapidly changing
system which will not keep still long enough for one to have a good look at it. For this reason …
