Abstract
This article investigates a scientific study of children conducted by Maria Lacerda de Moura from 1908 to 1921, and covers this educator’s trajectory in the city of Barbacena, the site of her writing, scholarship, and dissemination of her ideas on experimental psychology. Important sources for this research were her request to the Minas Gerais state Department of the Interior for authorization to conduct scientific experiments in the schools in Barbacena, and the subsequent responses. While the tests were identified, government resistance to the project was also seen, revealing different power relationships within the context of how experimental psychology was inserted into education.
