Around the clock surveillance: simple graphic disturbance in patients with hemispatial neglect carries implications for the clock drawing task

摘要

BackgroundDrawing, and the clock drawing task in particular, is widely used as a diagnostic tool in the study of hemispatial neglect. It is generally assumed that the errors in graphic production, such as the misplacement of numbers, reflect a visuospatial deficit, and that drawing production itself (for example, producing the circle) is unimpaired.
