In March 1996 I was administered the Wisconsin Card Sorting Test by a psychiatry resident (Ramin Mojtabai, M.D. under the supervision of Robert Jenkins, Ph.D.) at the George Washington University Medical Center.
I scored six errors. "[S]ix errors represent the best score possible." Matthew M. Kurtz, Ph.D., Sarah B.

The Wisconsin Card Sorting Test requires the individual to change strategy continually in response to feedback.
In February 1996, my then treating psychiatrist at GW (Dimitrios Georgopoulos, M.D.) diagnosed me with paranoid schizophrenia.
In September 1992 I had been diagnosed with bi-polar disorder, a mood disorder, by Napoleon Cuenco, M.D., at GW. In February 1993 my then treating psychiatrist (Suzanne M. Pitts, M.D., deceased) prescribed lithium for bi-polar disorder.
