I am aware that the Wisconsin Card Sorting Task (WCST) has been used multiple times to demonstrate [differences in executive function control in schizophrenics](http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1407748/), but what other mental illness sufferers have been demonstrated to have significant performance differences on the WCST?

I'll add more specific statistics (such as trials required to acquire first rule) and better references later.
