q4 i2 Arm training had a significant positive effect on the composite measure of letter knowledge and script (d = 0.404). → Fernando Núñez-Regueiro 2024 q4 i1 Arm-body training had a significant negative effect on the composite measure (d = -0.383). → Fernando Núñez-Regueiro 2024 (2)

Fernando Núñez-Regueiro, Natacha Boissicat, Fanny Gimbert, Céline Pobel-Burtin, Marie-Caroline Croset, Marie-Line Bosse, and Cécile Nurra. (2024).

q4 · i2 · causal · r3

Preregistered randomized-controlled experiment in 13 kindergarten classes; linear regression on a latent composite of letter knowledge and script, adjusted for baseline level and letter set (age and gender were tested and dropped from this model as non-significant). Arm training increased acquisitions by "+0.404 SD" versus the average student.

"the arm training condition had a significant, positive effect on overall acquisitions in letter knowledge and script on post-tests (ß = 0.148, d = 0.404, p = .008)"

q4 · i1 · causal · r3

Same RCT, linear regression on the composite measure: arm-body training decreased acquisitions by "-0.383 SD" relative to average students; the likelihood ratio test for the model was significant.

"the arm-body training condition had a significant, negative effect on overall acquisitions (ß = -0.138, d = -0.383, p = .033)"
