Abstract
Executive functions such as working memory, self-regulation, inhibitory control, are mental processes that enable the voluntary control of actions, thoughts and emotions. Executive functions play a key role in academic learning, as early as preschool. There exist stark inequalities in the distribution of executive functions at school entry, especially between children from different socio-economic background. This experiment aims at training executive functions in pre-schoolers by providing them with several sessions of pretend-play activities in small groups. Pretend-play activities are extracted from the Tools of the Mind curriculum. The experiment aims at measuring the short run impact of pretend-play activities on brain functioning, executive functions, child' s self-regulation, socio-affective skills and academic outcomes. The experiment uses a pairwise randomized controlled trial on a target on 70 children with a pre-post design if possible and a post design when not enough pre and post outcomes are available.

Experimental Design
Experimental Design
Parwise randomized controlled trial at the child level.
Children, aged from 4 to 6, come from 4 classes located in two schools.
Experimental Design Details
Parwise randomized controlled trial at the child level. Children, aged from 4 to 6, come from 4 classes located in two schools. Pairs were formed by minimizing the total sum of a Mahalanobis distance between children from the same class and the same EEG category (yes or no). Mahalanobis distance was computed using zEVIP, zCPM and zdots scores. Optimal pairs were computed using a non directed search algorithm sampling randomly pairs within strata and looking for the minimum distance.

70 children
Sample size (or number of clusters) by treatment arms
35 children
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Standard errors of the treatment effect estimator including pair fixed effects are of 0.122, 0.150 and 0.187, respectively, which implies a MDE (for one-sided t-test of size 5% and power 80%) of 0.303, 0.373 and 0.465 respectively. All variables are centered and standardized, so that MDEs are in units of standard deviation.
