This article reviews theoretical and empirical arguments for and against various theories that
explain the classic Ponzo illusion and its variants from two different viewpoints concerning …

Size constancy is the result of cognitive scaling operations that enable us to perceive an
object as having the same size when presented at different viewing distances. In this article …

One might think of visual processing as operating like an assembly line: subsystems work
out particular subcomponents that are combined to generate a final product, which is then …

Some everyday objects are associated with a particular color, such as bananas, which are
typically yellow. Behavioral studies show that perception of these so-called color-diagnostic …

Arguably the most foundational principle in perception research is that our experience of the
world goes beyond the retinal image; we perceive the distal environment itself, not the …

In the Ebbinghaus illusion, the context surrounding an object modulates its subjectively
perceived size. Previous work implicates human primary visual cortex (V1) as the neural …

Perception is subjective. Even basic judgments, like those of visual object size, vary
substantially between observers and also across the visual field within the same observer …

In natural scenes, objects rarely occur in isolation but appear within a spatiotemporal
context. Here, we show that the perceived size of a stimulus is significantly affected by the …

Neural activation in the early visual cortex (EVC) reflects the perceived rather than retinal
size of stimuli, suggesting that feedback possibly from extrastriate regions modulates retinal …

This book is about mental imagery and the important work it does in our mental life. It plays a
crucial role in the vast majority of our perceptual episodes. It also helps us understand many …
