Description
Summary:This study investigated the effects of different amounts and schedules of varied practice, after constant practice, on the adaptive process of motor learning. Participants were one hundred and seven children with a mean age of 11.1 ± 0.9 years. Three experiments were carried out using a complex anticipatory timing task manipulating the following components in the varied practice: visual stimulus speed (experiment 1); sequential response pattern (experiment 2); and visual stimulus speed plus sequential response pattern (experiment 3). In all experiments the design involved three amounts (18, 36, and 63 trials), and two schedules (random and blocked) of varied practice. The experiments also involved two learning phases: stabilization and adaptation. The dependent variables were the absolute, variable, and constant errors related to the task goal, and the relative timing of the sequential response. Results showed that all groups worsened the performances in the adaptation phase, and no difference was observed between them. Altogether, the results of the three experiments allow the conclusion that the amounts of trials manipulated in the random and blocked practices did not promote the diversification of the skill since no adaptation was observed. Este estudo investigou os efeitos de diferentes quantidades estruturas de prática variada, após a prática constante, no processo adaptativo de aprendizagem motora. Os participantes foram 107 crianças com idade média de 11.1 ± 0.9 anos. Três experimentos foram realizados usando uma tarefa de timing antecipatório complexo manipulando os seguintes componentes na prática variada: velocidade visuais estímulo (experimento 1); padrão de resposta sequencial (experimento 2), e velocidade de estímulo visual mais padrão de resposta sequencial (experimento 3). Em todos os experimentos, o design envolveu três quantidades (18, 36 e 63 ensaios), e dois regimes (aleatória e por blocos) da prática variada. Os experimentos também envolveram duas fases de aprendizagem: estabilização e adaptação. As variáveis dependentes foram os erros absoluto, variável e constante relacionados ao objetivo da tarefa, e o timing relativo para avaliar o padrão de resposta. Os resultados mostraram que todos os grupos pioraram os desempenhos na fase de adaptação, e nenhuma diferença entre eles foi observada. No seu conjunto, os resultados dos três experimentos permitem concluir que as quantidades de tentativas manipuladas nas práticas aleatória e por bloco
