Token Test Scores of Three Matched Patient Groups: Left Brain-Damaged with Aphasia; Right Brain-Damaged without Aphasia; Non-Brain-Damaged

The Token Test was administered to English speaking left braind-amaged aphasic, right brain-damaged nonaphasic and non-brain-damaged control patients who were matched across groups for age and educational level. In general, all patients had increasing difficulty as the parts progressed. The results are consistent with the findings of previous investigators in that the left brain-damaged aphasic patients made the greatest number of errors on all parts of the test, and no relationship was demonstrated between age and Token Test scores. An unexpected finding was that Parts IV and V differentiated the right brain-damaged nonaphasics from the control patients.
