Corrigendum: Is Cognitive Training Effective for Improving Executive Functions in Preschoolers? A Systematic Review and Meta-Analysis (Frontiers in Psychology, (2020), 10, 10.3389/fpsyg.2019.02812)

In the original article, there was an error because we wrongly coded four studies (Gade et al., 2017) as including a computerized training, which was not correct. In the Abstract, we stated that the condition computerized vs. non-computerized versions of the training was significant, but this was not the case. Moreover, in Table 1, we deleted “computerized” in the four studies published by Gade et al. (2017) and on Table 3, we corrected the values related to “computerized vs. non-computerized trainings”. Supplementary Data Sheet 2 has been corrected and updated. Corrections have also been made to Table 1, Table 3, as well as the following paragraphs indicated below.
