Updating and Not Shifting Predicts Learning Performance in Young and Middle-Aged Adults

The goal of this study was to investigate whether single executive function (EF) tests were predictive for learning performance in mainly young and middle-aged adults. The tests measured shifting and updating. Processing speed was also measured. In an observational study, cognitive performance and learning performance were measured objectively in 851 adult students and analyzed using multiple linear regression. EFs and processing speed were measured via cognitive tests. Learning performance was evaluated after 14 months. The results show that updating performance is predictive for learning performance, with a small effect size, while shifting performance was not. This means that a single updating test has predictive value for learning performance acquired over a longer period of time. However, as the effect size is rather small, the test on its own does not serve as a proper selection tool for determining whether a student will be successful or not.
