About 40 years ago, James J. Gibson coined the term “affordance” to describe the action
possibilities offered to an animal by the environment with reference to the animal's action …

The execution of complex visual, auditory, and linguistic behaviors requires a dynamic
interplay between spatial ('where/how') and non-spatial ('what') information processed along …

The fully updated eighth edition of Cognitive Psychology: A Student's Handbook provides
comprehensive yet accessible coverage of all the key areas in the field ranging from visual …

The perception–action model proposes that vision-for-perception and vision-for-action are
based on anatomically distinct and functionally independent streams within the visual cortex …

Posterior parietal cortex (PPC) plays an important role in the planning and control of goal-
directed action. Single-unit studies in monkeys have identified reach-specific areas in the …

Evidence is strong that the visual pathway is segregated into two distinct streams—ventral
and dorsal. Two proposals theorize that the pathways are segregated in function: The …

Much of the central nervous system is involved in visuomotor transformations for goal-
directed gaze and reach movements. These transformations are often described in terms of …

Optic ataxia is a high-order deficit in reaching to visual goals that occurs with posterior
parietal cortex (PPC) lesions. It is a component of Balint's syndrome that also includes …

Single-unit recordings in macaque monkeys have identified effector-specific regions in
posterior parietal cortex (PPC), but functional neuroimaging in the human has yielded …

We are delighted to see the impressive range of empirical and theoretical research that has
been inspired directly or indirectly by our Two Visual Systems (TVS) model. The utility of a …
