STANDARDIZED ANALYSIS OF VISUOSPATIAL PER CEPTION (US) - PROCEDURES AND APPLICATIONS

Assessment of visuo-spatial perception (VS) in brain-damaged patients. So far, no comprehensive methods for reliable assessment of visuo-spa tial deficits after brain damage have been described. The tests usuall y applied are subtests of intelligence tests., paper-pencil tests or v isual-constructive tests which also require motor and planning abiliti es. Almost all these methods are unsuitable for measuring therapeutic changes and do not reveal specific impairments. The computational meth od presented here (VS) is suitable for the quantitative assessment of visuo-spatial functions, e. g. subjective visual vertical and horizont al; orientation, length, distance, form and position discrimination as well as line bisection. It can easily be installed on an IBM compatib le PC. A clinical standard examination can be performed within 20-30 m inutes including numerical and graphical analysis of the results. The method is sensitive for measuring therapeutic changes. Moreover, it of fers a wide range of experimental task manipulations for more sophisti cated experimental tests.
