In cognitive psychology, visuospatial function refers to cognitive processes necessary to "identify, integrate, and analyze space and visual form, details, structure and spatial relations" in more than one dimension. [1] Visuospatial skills are needed for movement, depth and distance perception, and spatial navigation. [1]
It is also involved in tasks which consist of planning of spatial movements, like planning one's route through a complex building. The visuospatial sketchpad can be split into separate visual, spatial and possibly kin-aesthetic (movement) components. Its neurobiological function also correlates within the right hemisphere of the brain. [24]
Visuospatial dysgnosia, along with Balint's syndrome, has been connected with Alzheimer's disease as a possible early sign of the disease. [2] Generally, the first symptom of Alzheimer's onset is loss of memory, but visual or visuospatial dysfunction is the presenting symptom in some cases [3] and is common later in the disease course. [4]
A common method in quick detection of visuospatial extinction is a Finger Confrontation Model. Utilized as standard bedside evaluation, the task requires the patient to indicate (either verbally or by pointing) in which visual field the doctor's hand or finger is moving, while the doctor makes a wiggling motion with his index.

Eidetic memory (photographic memory) may co-occur in visual thinkers as much as in any type of thinking style as it is a memory function associated with having vision rather than a thinking style. [ citation needed ] Eidetic memory can still occur in those with visual agnosia , who, unlike visual thinkers, may be limited in the use of ...
Many different cognitive abilities are needed for a correct performance, and the test therefore permits the evaluation of different functions, such as visuospatial abilities, memory, attention, planning, working memory and (executive functions).
The two-streams hypothesis is a model of the neural processing of vision as well as hearing. [1] The hypothesis, given its initial characterisation in a paper by David Milner and Melvyn A. Goodale in 1992, argues that humans possess two distinct visual systems. [2]
