Sign comprehension in global aphasia.
Ten global aphasics and eight brain-damaged non-aphasics were given a test of sign comprehension. The test contained natural, animal and human signs. Subjects were matched for etiology, age and residual intellectual functioning. The global aphasics scored significantly lower than the nonaphasics on the test of sign comprehension, indicating that global aphasia might be reconsidered as a disorder of sign comprehension.
