Project ExFunKi

Executive Function in Preschool

The aim of the ExFunKi project is to adapt, standardize and validate a computerized test battery measuring executive functions at the age of 3–5 years for Germany. Test battery and standards should be available for free.

Executive functions are control processes that are necessary to behave adaptively and purposefully in new, unfamiliar situations. They are an important prerequisite for the successful accomplishment of various developmental tasks at pre-school and school age. Deficits in executive functions could lead to ADHD or poor school performance.

It is difficult to diagnose executive functions in preschool age because behavioral observations, which are usually used, are complex and not sufficiently valid. One solution would be the development of a computerized test battery to measure executive functions at pre-school age. The aim of the ExFunKi project is to adapt, standardize and validate such a battery from English to German.

ExFunKi is a cooperation project between

  • Helmut Schmidt University,
  • University of Tübingen,
  • University of Koblenz and Landau,
  • University Leipzig.
