Efeitos da ilusão visual na aprendizagem de uma tarefa adaptada de Fitts

Abstract

Recent studies have shown that practicing motor tasks with visual illusions that make the perceived targetto be largerthan it really is, lead to improvements in performance and motor learning. The purpose of this research is to investigate the Ebbinghaus Illusion effects on the learning of a continuous task involvingprecision and speed inadolescentand underlying possible mechanisms ofsuch effects. The sample will be composed of 30 adolescents,randomly selected, allocated by gender and agein the different groups. Theparticipants willperform under differentvisual illusions relative to sizeperception. They’llbe divided into three groups:Large Target Perception (LTP)andSmall Target Perception (STP). The LTPgroup will practice on targets containing 11 small circles around a centralstandardcircle, creating the illusion of a larger target. The STP group will practice with 6large circles around a central circle, creatingthe illusion of a smaller target. The study will be composed ofa pre-test (without illusions),acquisition,retention,andtransfer phases. Questionnaires will be used to evaluate motivational aspects
