Visual perception is a complex process engaging many different aspects of brain functioning. Like other cognitive functions, the extensive cortical distribution and complexity of visual perceptional activites make them hihgly vulnerable to brain injury. Dectection and characterization of perceptual disorders require a careful clinical assessment as well as the application of selected neuropsychological tests. In this article we reviewed neuropsychological assessment of visual perception and constructional abilities. And the principal visuospatial disorders are discussed, the associated neuropsychiatric disorders are presented.

Objective : This study investigated the relationships of handwriting legibility and perceptual-motor skills, and handwriting speed and perceptual-motor skills. And identified the predictors that most affect the handwriting of preschool children. Methods : Twenty-three typically developing preschool aged children (mean age: 68.61 months, SD=2.04) were selected through the Korean-Denver Developmental Screening Test-2(K-DDST-2). The children were tested with regard to handwriting legibility, visual perception, visual-motor integration and fine-motor coordination. Results : First, a significant relationship was not found among handwriting legibility, visual perception, visualmotor integration and fine-motor coordination. Second, a significant relationship was found among handwriting speed, visual perception and fine-motor coordination. Third, stepwise multiple regression analyses showed that general visual perception were significant predictors for handwriting speed. Conclusion : Occupational therapists should evaluate children's visual perception levels utilizing a standardized test, and focus on general visual perception in order to improve handwriting skill(speed). Also, occupational therapists are expected to play an important role in the management and treatment of children's handwriting skills.
