Estrutura de prática e complexidade da tarefa no processo adaptativo de aprendizagem motora

Abstract

PRACTICE SCHEDULE AND TASK COMPLEXITY IN THE ADAPTIVE PROCESS OF MOTOR LEARNING Author: JANE APARECIDA DE OLIVEIRA SILVA Adviser: UMBERTO CESAR CORREA 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.
