Explain the Executive Functions - Psychological tests

Executive functions are those involved in the planning, organisation, regulation and monitoring of goal directed behaviour. In the past, the assessment of those skills and related abilities, such as problem solving and abstract reasoning, has often been conducted informally, often by examining the quality of performance on tests falling within other measurement domains. Recently however, a wider variety of tests has been employed to assess executive functions, including measures such as Wisconsin Card Sorting Test, the Tower of London, and the Children's Category Test. Executive Function would appear to play a critical role in determining a child's adaptive functioning.
