Influence of information sources on efficiency of motor learning:verbal instruction, visual modelling and knowledge of performance

Motor learning is a process of establishing a motor skill that could be defined as ability of harmonious and coordinate performance of certain motor task. This experiment tested the influence of the sources and amount of information on the efficiency in the learning one complex motor task.The experimental design represented an upgrade of Magill and Schoefendler-Zhodi experiment (1992). The sample was comprised of 65 1st year female students of the Faculty of Kinesiology from Zagreb, divided in six experimental groups, who were learning a complex skill of rhytmic gimnastics (element with rope) through 48 trials organised in 8 series. They were learning based on different initial learning instructions (the verbal, visual or combined verbal-visual) and with or without feedback (KP). The results obtained by a 3x3x8 ANOVA with repeated measures show that the amount of initial information a beginner has at her/his disposal is important in learning a complex motor skill. Learning is more effective if an intial instruction is either visual or combined. Learning is faster and a level of acquisition is higher if a begginer receives augmented feedback nformation. Instructions of different levels of complexity bring different information to a begginer.When instruction is verbal, basic mistakes are more frequent, whereas other types of instructions bring enough information for the acquisition of the basic motor pattern.Mistakes in performance, which may occur, are more mistakes of upgrading the skill learning, and they are related to the coordination or manipulation demands in the performance of a complex motor skill.
