Research Findings: This study aims to evaluate the efficacy of linguistic training based on the use of the Drežancic method in educational settings. It is hypothesized that characteristics of this method, based on the typical stages of linguistic and cognitive development, could influence both language competence and executive function (EF). A pretest-posttest treatment design with a control group was used to evaluate the efficacy of the method (preintervention baseline and posttraining after 6 months). A total of 41 children (ranging in age from 26 to 31 months) with a vocabulary size score lower than the 50th percentile were recruited to participate in the study and were assigned to 2 groups: an experimental group that received training or a control group that participated in normal day care center activities. The results revealed that the training had an effect: The experimental group produced a greater variety of words and more complete sentences; moreover, the linguistic training appeared to positively affect EF processes. Practice or Policy: The results highlight the efficacy of a training, applicable to educational contexts, for typically developing populations. Furthermore, the confirmation of a rich interaction between language and EF even at an early age has important implications for clinical work.
