Abstract

Demonstration, verbal instruction and knowledge of results are variables presented during the process of motor skills acquisition but their interaction was not investigated. This question was tested with three frequencies of knowledge of results plus three ways to supply prior information (demonstration, verbal instruction and demonstration added to the verbal instruction). The task consisted of carrying three tennis balls in a predetermined sequence and target time. A hundred eight volunteers participated in the study, divided into nine groups according to the combination of variables. The experiment consisted of the acquisition phase with 60 trials of practice and tests and data reliability was tested through two way ANOVA. The results showed that demonstration and KR conducted to better performance during tests.
