I was taking the Iowa Gambling Task. I examined what happens when the same option is selected on every run. To my surprise I got a pretty good value when choosing options C and D (\$4500) in every run and a pretty bad one ($-500) with options A and B.
Is this intended by the test or is it a bug / feature of my downloaded program?
(I got $4700 when mixing some A's among plenty of C's)
