Title in Portuguese
Estrutura de prática e complexidade da tarefa no processo adaptativo de aprendizagem motora
Keywords in Portuguese
Aprendizagem motora
Complexidade da tarefa
Estrutura de prática
Processo adaptativo
Abstract in Portuguese
O objetivo desse trabalho foi investigar os efeitos da estrutura de prática no processo adaptativo de aprendizagem motora em razão da complexidade da tarefa. Os participantes foram 160 crianças de ambos os gêneros e a tarefa foi de timing coincidente. No experimento 1, as crinaças executaram uma tarefa que consistiu tocar certos alvos de forma seqüencial em integração a um estímulo visual (tarefa simples) e, o experimento 2, uma tarefa com 6 toques (tarefa complexa). O delineamento dos dois experimentos constou de quatro grupos (prática constante, prática aleatória, prática constante-aleatória, e prática aleatória-constante) e de duas fases de aprendizagem (estabilização e adaptação) As variáveis dependentes foram os erros absoluto, variável e constante. Os resultados mostraram que a complexidade da tarefa afetou os efeitos da estruturação da prática no processo adaptativo de aprendizagem motora. Verificou-se que, para a aprendizagem da tarefa simples, a adaptação ocorreu com similar desempenho para os quatro grupos, enquanto que para a tarefa complexa, o desempenho foi pior para o grupo constante

Abstract in English
The objective of this work was to investigate the effects of practice schedule in the adaptive process of motor learning in reason of task complexity. The participants were one hundred and sixty children of both gender and the task was of coincident timing. In the experiment 1 the children performed a task that consisted of touching four response keys sequentially in conjunction with a visual stimulus (simple task), and, the experiment 2, the task evolved six touches (complex task). The experimental design of both experiments consisted of four practice groups (constant, random, constant-random and random-constant) and two learning phases (stabilization and adaptation). Dependent variables were absolute, variable and constant errors. The results show that task complexity affected the effects of practice schedule in the adaptive process of motor learning. It was verified that for learning of simple task the adaptation occurred with similar performance for all groups, while the complex task occurred worse performance for constant group
