Determining Practice Effects on a Cognitive Flexibility Assessment

The Youmans Cognitive Flexibility Assessment (YCFA) was created as an easy-to-administer and entertaining assessment of cognitive flexibility. Although a validation and reliability study of the YCFA was conducted, practice effects were not assessed. This present study aims to uncover whether practice effects occur for the YCFA. Thirty-six undergraduate university students completed four rounds of the YCFA (six trials per round). Practice effects occurred in the first and second rounds, but task performance stabilized after the third round. Implications are discussed.
