Response inhibition: training and effects linked to the level of inhibition in pre-test, in children

Abstract

From non-unitary perspective of inhibition, three inhibitory processes are identified: perceptual, cognitive and response inhibition. Response inhibition allows suppressing prepotent and inappropriate responses for the current purposes. In the last years, different interventions targeted at optimizing it during the first years of school period. However, the studies are insufficient to understand the efficacy of the interventions on response inhibition and other inhibitory processes, both short- and long-term; and the characteristics that are linked to the results. The goals aims: to analyze the efficacy of a response inhibition training on this process and perceptual inhibition, both short- and long-term, in children in the first years of elementary school; and to analyze if the relationships of age and the level of inhibition in pre-test are related to the results. The participants (93 children, from 6 to 8 years old) were assigned to a training or a control group, in an experimental design, with a pre-test and two post-tests. We observed effects in the short term on children’s performance on a response inhibition task. The children who benefited more from the intervention were those who started the intervention with a lower level of inhibition. We discuss the contribution of these results to non-unitary perspective, the scope of the interventions and the study of the participants’ characteristics related to the results.
