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]
Neuropsychological tests of visuospatial function should cover the areas of visual perception, visual construction and visual integration. [9] Though not their only functions, these tasks are to a large degree carried out by areas of the parietal lobe. [3]
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 ...
The executive functions are among the last mental functions to reach maturity. This is due to the delayed maturation of the prefrontal cortex, which is not completely myelinated until well into a person's third decade of life. Development of executive functions tends to occur in spurts, when new skills, strategies, and forms of awareness emerge.
Baddeley and Hitch's model of working memory. In 1974 Baddeley and Hitch [11] introduced the multicomponent model of working memory.The theory proposed a model containing three components: the central executive, the phonological loop, and the visuospatial sketchpad with the central executive functioning as a control center of sorts, directing info between the phonological and visuospatial ...
