Studies have narrowed the area of the brain that, when damaged, causes visuospatial dysgnosia to the border of the occipito-temporoparietal region. [1] Predominantly, lesions (damage, often from stroke) are found in the angular gyrus of the right hemisphere (in people with left-hemisphere language), and are usually unilateral, meaning in one hemisphere of the brain.
Topographical disorientation is the inability to orient oneself in one's surroundings, sometimes as a result of focal brain damage. [1] This disability may result from the inability to make use of selective spatial information (e.g., environmental landmarks) or to orient by means of specific cognitive strategies such as the ability to form a mental representation of the environment, also known ...
Spatial ability or visuo-spatial ability is the capacity to understand, reason, and remember the visual and spatial relations among objects or space. [ 1 ] Visual-spatial abilities are used for everyday use from navigation, understanding or fixing equipment, understanding or estimating distance and measurement, and performing on a job.
Spatial intelligence is an area in the theory of multiple intelligences that deals with spatial judgment and the ability to visualize with the mind's eye. It is defined by Howard Gardner as a human computational capacity that provides the ability or mental skill to solve spatial problems of navigation, visualization of objects from different angles and space, faces or scenes recognition, or to ...
For example, he called an abacus "skewers on a kebab" and a badminton racquet a "fencer's mask". A dart was a "feather duster" and a protractor was mistaken for a "cockpit". Despite this impairment in visual object recognition, C.K. retained many abilities such as drawing, visual imagery, and internal imagery.
The Corsi block-tapping test, also known as the Corsi span rest, is a psychological test commonly used to determine the visual-spatial memory span and the implicit visual-spatial learning abilities of an individual. [23] [24] Participants sit with nine wooden 3x3-cm blocks fastened before them on a 25- x 30-cm baseboard in a standard random ...
The cognitive tests used to measure spatial visualization ability including mental rotation tasks like the Mental Rotations Test or mental cutting tasks like the Mental Cutting Test; and cognitive tests like the VZ-1 (Form Board), VZ-2 (Paper Folding), and VZ-3 (Surface Development) tests from the Kit of Factor-Reference cognitive tests produced by Educational Testing Service.
Although it most strikingly affects visual perception ('visual neglect'), neglect in other forms of perception can also be found, either alone or in combination with visual neglect. [5] For example, a stroke affecting the right parietal lobe of the brain can lead to neglect for the left side of the visual field, causing a patient with neglect ...
