The Psychology Experimental Building Language http://pebl.sourceforge.net/Berg Card Sorting Test is an open-source neurobehavioral test. Participants (N = 207, ages 6 to 74) completed the Berg Card Sorting Test. Performance on the first 64 trials were isolated and compared to that on the full-length (128 trials) test. Strong correlations between the short and long forms (total errors: r =. 87, perseverative response: r =. 83, perseverative errors r =. 77, categories completed r =. 86) support the Berg Card Sorting Test-64 as an abbreviated alternative for the full-length executive function test. © 2013 Fox et al.
