Early Years Toolbox (EYT) Card Sorting is an iPad-based assessment of children's cognitive flexibility (i.e., ability to disengage from one task/rule and re-engage in another). In this game, children are presented with rabbits and boats that vary along two dimensions (i.e., shape and colour). Children and are asked to sort each the rabbits and boats first by one dimension (e.g., colour) and then, after a number of trials, by another dimension (e.g., shape). This game takes approximately 5 minutes to complete. Scores are presented on the final assessment screen. For more precise research applications, there are options to have the item by item data sent to a user-specified e-mail address or database.
