Abstract:	Aging causes changes that affect functioning of cognitive processes such as cognitive flexibility (CF). Given it allows changing both behavior and thinking in dynamic contexts, it constitutes an essential trait of adaptive, goal-oriented behavior. Despite its importance, specific techniques to evaluate CF in older adults are lacking. The goal of this article is to describe and comparatively analyze the functioning of CF in a sample of 169 individuals representing three age groups-younger-age, middle-age and advanced-age adults-by obtaining evidence of internal and external validity. Using a correlational and cross-sectional research design, four studies were conducted in order to evaluate construct validity-fulfillment of experimental paradigm criteria and contrast between groups and tests with different methods. In addition to the Fingers Task, the study used the CAMBIOS Cognitive Flexibility Test, TAC's Conjunction Visual Search Task (which evaluates perceptual inhibition) and a verbal fluency task with changes. The results provide evidence of the functioning of CF in adulthood and advanced age, which has implications for neurocognitive clinical evaluation in these stages of life. Additionally, evidence was obtained in favor of the concurrent validity of the instruments used to measure CF, contributing to the solidity of future studies on this executive function.
