Résumé

This randomized controlled trial included 50 healthy older adults, divided into AI-based individualized adjustment ( ZPDES ) and traditional staircase (control) groups. We assessed task performance progression, cognitive transfer across seven tasks, interindividual differ- ences, and subjective experiences via questionnaires. Pre-post comparisons revealed greater training benefits in the MOT task for the ZPDES group. Specific task improvements were noted only in the control group, but no differences were observed at a latent level. Both groups exhibited non-linear intra-training progress: control participants improved initially and then plateaued, while ZPDES participants showed consistent progress throughout the two weeks of training. For both conditions, interindividual differences in prior MOT performance significantly influenced baseline performance in the first training session, but no significant differences were found in performance changes. Differences in training trajectories led to varied subjective experiences: cognitive load decreased more over time for the control group, indicating ZPDES was more demanding. Participants in the ZPDES group reported lower intrinsic and extrinsic motivation but a higher sense of competence. In sum, the ZPDES condition demonstrated greater post-training MOT performance, consistent intra-training progress, and higher competence, despite being more demanding. Consequently, this study discusses the implications of our approach on training benefits, experience, and engagement, and proposes improvements to the ZPDES algorithm to better address interindividual differences in cognitive aging.
