Game-based cognitive training and its impact on executive functions and math performance: A randomized controlled...

Executive functions (EFs) are the focus of interventions aimed at their development and subsequent improvement of indirectly trained skills such as academic performance. Therefore, the objective of this study was to evaluate the presence of near-transfer effects (EFs improvement) and far-transfer effects (mathematics improvement) of the Cucca Curiosa intervention in Brazilian children aged 7 to 10 years, with 28 participants per age group. This stratified trial included 112 children randomly assigned to the experimental group (EG) or control group (CG). Child Brief Neuropsychological Assessment Battery  (NEUPSILIN-Inf), Five-Digit Test (FDT), Day-Night Stroop task, and Mathematics Test (TEMA) were administered at pretest and posttest levels. The EG participated in the 1-week Cucca Curiosa program, consisting of five sessions (averaging 13 min, with a maximum of 26 min), whereas the CG remained in passive waiting. Data analysis revealed that the intervention significantly improved children's executive and mathematics performance in the short term. The mediation analysis identified that EFs are essential mediators that explain how the intervention improves mathematical performance, reinforcing the importance of focusing on the development of EFs as a strategy to improve academic performance. Further studies are necessary to assess long-term effects, transfer to other skills, and potential benefits in reducing psychopathological symptoms.
