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. For more information, training videos and analysis resources, please visit http://www.eytoolbox.com.au

About the Early Years Toolbox:

The 'Early Years Toolbox' (EYT, for short) is comprised of brief, engaging game-like assessments of children’s self-regulation, executive functioning and vocabulary. These assessments are based on well-established and widely used measures, yet have been adapted and optimised on the basis of 20+ years of research experience working with young children.

Nice app!

This app requires young children to sort the same items by different characteristics. First, the sort is by color, then by shape. So, when sorting by color, the boat might go on the rabbit side if the color is the same. However, the same boat will go on the boat side if the sort is now by shape. Low-key, but enjoyable, for the children -- while I get information about their strengths and challengies.
