Dependent Variables Analyzed for theWisconsin Card Sorting Test (WCST) and the Card Sorting Test (CST)
| Measure | Description |
|---|---|
| Experiment 1: WCST | |
| % Conceptual level responses (CLR) | Percentage of responses indicating a conceptual understanding of the task (e.g., at least 3 correct category responses in a row) |
| % Errors (ERR) | Percentage of error responding regardless of type |
| % Perseverative responses (PR) | Percentage of responses, correct or incorrect, that indicate a perseverative response style or failure to change strategies when appropriate |
| % Perseverative errors (PE) | Percentage of perseverative errors |
| % Nonperseverative errors (NPE) | Percentage of nonperseverative errors |
| Experiment 2: CST | |
| Confirmed correct verbal | Number of correctly sorted and identified verbal sorts |
| Confirmed correct perceptual | Number of correctly sorted and identified perceptual sorts |
| Percent accuracy sorting | Percent of total sorts attempted that were correct |
| Percent accuracy description | Percent of total descriptions attempted that were correct |
| Repeated sorts | Number of repeated sorts made during the free sorting condition |
| Set loss errors | Number of times the subject fails to observe the basic task instructions (e.g., 4 cards in 1 group, stacking cards) |
| Nontarget even sort | Number sorts that follow task instructions but do not match 1 of the 8 identified sorts |
| Repeated descriptions / free | Number of repeated descriptions made during the free sorting condition |
| Incorrect description / free | Number of incorrect descriptions made during the free sorting condition |
| Structured description score | Description score for the structured sorting condition |
| Incorrect description / structured | Number of incorrect descriptions on the structured condition |
| Repeated description / structured | Number of repeated descriptions on the structured condition |
