The cognitive flexibility (CF) puzzle is a task designed to measure people’s ability to effectively switch between different mental rule sets. The task is based off of existing measures of CF, the Trail Making Task and the Wisconsin Card Sorting Task and has been previously validated.
The application provided here allows researchers to create and administer multiple experiments. Response times and errors are exported to text files for analysis.
Two versions are available for download, one with randomized presentation order (CF Puzzle-rand) and one with fixed presentation order (CF Puzzle-!rand).
The CF puzzle was developed by Dr. Robert Youmans and Christian Gonzalez and programmed in AdobeⓇ FlashⓇ by Dustin Rhodes. See below for more information
