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]
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.
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.
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).
Visuospatial abilities are assessed using a clock-drawing task (3 points) and a three-dimensional cube copy (1 point). Multiple aspects of executive function are assessed using an alternation task adapted from the trail-making B task (1 point), a phonemic fluency task (1 point), and a two-item verbal abstraction task (2 points).
Judgment of Line Orientation (JLO) is a standardized test of visuospatial skills commonly associated with functioning of the parietal lobe in the right hemisphere. [1] The test measures a person's ability to match the angle and orientation of lines in space. [2]
Visuospatial skills are used almost daily to remember directions, addresses, and layout of familiar places. [10] Visuospatial abilities are tested by asking the patient to copy two diagrams; to draw a clock face with the hands set at a specified time; to count sets of dots; and to recognize four letters which are partially obscured.
The Benton Visual Retention Test is composed of 3 sets, or forms, of 10 designs (each 8.5 × 5.5 in.) that measure the examinee's visual and memory abilities as well as a set of alternate designs for repeated tests. [4] The examinee is given a booklet containing 10 blank pages on which they reproduce the designs.
