Imagery training has been shown to induce motor learning in adults, but similar evidence in children is scarce. In this experiment, we aimed to evaluate the effect of association between imagery and physical practice compared to pure physical practice in the learning of a manual task in 9-10 year-old children. The task consisted of transporting a block and fitting it into a support with speed and steadiness, assessing movement time to complete the "reaching" and "transport" task components.
The children were assigned to one of three groups:
(a) physical practice (PHYS) (240 trials), (b) combination (COMB) of imagery (180 trials) and physical (60 trials) practice, and (c) control (CON), associating visual rotation (180 trials) and physical practice (60 trials). Performance was evaluated immediately and 24 h after practice. Results indicated that the PHYS group achieved a persistent performance gain in the "transport", but not in the "reaching" task component, while the COMB group achieved persistent performance gains in both movement components; no significant differences were found for the CON group. Our results suggest that imagery training improves the task mental representation in children, while physical practice provides sensory feedback on the performed movements. As a conclusion, the results suggest that combination of imagery and physical practice can be more effective than pure physical practice for children's motor learning.
Imagética dos próprios movimentos tem mostrado induzir aprendizagem motora em adultos, porém são escassas evidências similares em crianças. O objetivo deste experimento foi avaliar o efeito da associação entre prática imagética e prática física em comparação com prática física pura em uma habilidade manual em crianças de 9-10 anos de idade. A tarefa consistiu em transportar um bloco e encaixá-lo em um suporte com rapidez e estabilidade, avaliando-se o tempo de movimento para completar os componentes de "alcance" e "transporte".
