In the present meta-analysis we examined the near- and far-transfer effects of training components of children's executive functions skills: working memory, inhibitory control, and cognitive flexibility. We found a significant near-transfer effect (g+ = 0.44, k = 43, p < .001) showing that the interventions in the primary studies were successful in training the targeted components. However, we found no convincing evidence of far-transfer (g+ = 0.11, k = 17, p = .11). That is, training a component did not have a significant effect on the untrained components. By showing the absence of benefits that generalize beyond the trained components, we question the practical relevance of training specific executive function skills in isolation. Furthermore, the present results might explain the absence of far-transfer effects of working memory training on academic skills (Melby-Lervag & Hulme, 2013; Sala & Gobet, 2017).
