Efeitos da frequencia do conhecimento de resultados controlada pelo experimentador e auto-controlada pelos sujeitos na aprendizagem de tarefas motoras com diferentes complexidades

The purpose of this work was to verify the effects of the frequency of knowledge of results (Kr), controlled by the experimenter and self-controlled by the subjects, in the learning of sequential motor tasks with different complexities. Two hundred and forty students from FMH were used as subjects, distributed in different groups regarding the different tasks (simple, intermediate or complex), the different Kr frequencies and the type of frequency used (controlled by the experimenter or self-controlled). The tasks required participants to press keys on the computer numeric keyboard, with different spatial and temporal requirements, manipulated in order to modify their complexity. No significant differences were found in the interaction between the frequency of Kr and the complexity of the task, as well as between classical Kr frequencies controlled by the experimenter and frequencies close to the classical, self-controlled by the subjects. Also, comparisons between different self-controlled frequency schedules showed no differences between subjects who requested a lot of or few K Rs, however, subjects which requested more Kr at the initial stage. Such results partly agree with those found in other researches of the areaAvailable from Fundacao para a Ciencia e a Tecnologia, Servico de Informacao e Documentacao, Av. D.
