Protocol - Cognitive Flexibility (Dimensional Change Card Sort) - Young Children
The Dimensional Change Card Sort (DCCS) Standard Version is an interviewer-administered task that measures the flexible use of rules to govern behavior as a means of providing an index of executive function in young children. In this task, the assessor asks the participant to sort bivalent test cards according to one dimension (e.g., color) and then the other (e.g., shape).
The Dimensional Change Card Sort task is a freely available, simplified version of the Wisconsin Card Sort test. For more information about the Wisconsin Card Sort test, please refer to the Cognitive Atlas Interpretation.
Summary of the Dimensional Change Card Sort (DCCS) Standard Version
The Dimensional Change Card Sort (DCCS) Standard Version makes use of two different styles of bivalent cards, displaying for example a red boat and blue rabbit.
The protocol consists of the following four steps:
1. The assessor decides which dimension (e.g., color or shape) on the bivalent cards will be used for the pre-switch phase of sorting.
2. The assessor sets up two sorting trays displaying target cards representing the two different styles of card. The participant is then given instructions for sorting a set of test cards, which displays the same images as the target cards, based on the dimension decided upon in step 1. The assessor guides the participant through the process of appropriately sorting one of each style of card.
3. The pre-switch phase of testing is carried out. The assessor instructs the participant to sort six randomly selected test cards based on the dimension selected in step 1.
4. The post-switch phase of testing is carried out. The assessor instructs the participant to sort six randomly selected test cards based on the other dimension.
Typically, post-switch performance is only evaluated for participants who correctly sort five or more of the six pre-switch cards. Participants are scored as having passed or failed the task as scores are usually bimodally distributed between being all correct or all incorrect on post-switch trials. Participants who correctly sort five or more of the six post-switch cards are considered to have passed the task.
Most healthy three-year-old children fail the post-switch phase of the standard version of the DCCS, exhibiting inflexibility, while most healthy four- and five-year-old children pass as their flexibility increases.

Personnel and Training Required
The assessor should be trained to respond in a neutral, nonevaluative, noncorrective manner during the task. The assessor should be trained in how to respond to hesitant or resistant behavior by the participant.
The assessor will need two sorting trays with panels for displaying target cards, two styles of bivalent target cards (e.g., one card displaying a red boat and the other a blue rabbit), and 14 standard test cards (7 of each style of target card).

Mode of Administration
Children aged 2.5-7 years
This Dimensional Change Card Sort (DCCS) Standard Version is a well validated measure of one aspect of executive control-cognitive flexibility-which can be used with preschoolers.

This measure assesses flexibility in detection and use of rules that govern behavior.
Cognitive flexibility is one component of the multidimensional construct "executive function." This measure provides a marker of the development of executive function. Substance use has been shown to correlate with deficits in both cognitive flexibility and other aspects of executive functioning.
