Dear Shane,
 
I have a couple of questions regarding the Wisconsin Card Sorting test.
I have noticed that that the three rules (shape, color and number) are
presented a different number of times each time the task is run. Could
the program be made to present each of them the same number of times
(i.e., 3) in an experiment (in randomized order, of course)?
 
I have also noticed a couple of problems in the report file:
 
- the number of trials appearing in the report file is always 1 unit
greater than the actual number of trials presented (according to the
output file). 
- the number of perseverations is always "0" no matter how many
responses one gives according to a no longer valid rule.
 
Thanks for your time,
