<unk>  disabilities are often tested by asking the patient to draw a 2D model or assemble an object. Some researchers feel that neuronal mechanisms involved in drawing and copying differ, thus they should be tested individually. Free drawing is a commonly used test in which the patient is asked to draw a named object. It can be an effective tool in measuring the patient's ability to maintain spatial relations, organize the drawing, and draw complete shapes. The complexity of the task should be noted as such tasks often require lexical-semantic abilities as well as imagery abilities.
