Diagnosis is achieved through several related methods. One approach involves having patients sit in front of a computer screen, on which either stars or triangles are projected simultaneously in different areas of the screen. Patients are then asked to identify the locations and identities of the shapes. Another similar approach is to project colored letters on the screen, again asking patients to identify the letter and color in different parts of the screen. From this information, a diagnosis of<unk>  can be attained. A positive diagnosis results from a patient's inability to correctly identify shapes or letters projected simultaneously in different areas of the screen. However, the most common test for<unk>  is the finger confrontation model. In this test, the doctor asks the patient to note which of his hands have moving fingers. This can be used immediately following a stroke, for the doctor's quick diagnosis.
