The authors created the CCS as a standard method of psychological assessment of executive functions development. Design of the CCS is based on the Dimensional Change Card Sort \(DCCS\) commonly used in scientific research with children. The tool was tested in a pilot study with 49 children aged 3–11. The results showed a similar pattern of scores as in the DCCS to give a good starting point to design a final version of the CCS."]
