Are the differences in the development of the executuve functions of children with a typical and atypical development stimulated by a game on a tablet?

Introduction: Executive functions (EF) are developed early, building a fundamental basis of higher cognitive processes in adulthood (Garon et al., 2008). There are studies with children of typical development (Passolunghi et al., 2006; Welsh et al., 2010) that have demonstrated the key role of EF, such as working memory, inhibitory control, planning and attentional flexibility, in initial literacy and precalculus. What is still unclear is whether these EF can be stimulated early and if it has any effect on their development. At the same time, it is known that children with atypical development, such as ADHD, have deficiencies in the development of EF (Barkley, 1997). Early stimulation of EF in this type of population will have the same effects as in a typical development population? The objective of the study is to evaluate the effect of a stimulation program of the EF (working memory, inhibitory control, planning and attentional flexibility), by means of a tablet digital game, in the development of the EF of preschool children with and without symptoms of ADHD, of socioeconomically disadvantaged sectors. Method: Two groups, control (CG) and intervention (IG) were selected at random, both were evaluated twice (before and after). In total there were 408 participants, 212 with typical development and 196 with atypical development. The IG was exposed to a digital game of EF through a tablet during 12 sessions (in the classroom). Results: The main results show differences in favor of IG in the different EF evaluated, both for children with and without ADHD symptoms, with the exception of attentional variable for which no differences were observed. There are differences in the effect of EF among children evaluated. Discussion: These differences and their possible implications in the educational and social environment are discussed
