Effect of the consequence memory training program on youth motor memory performance: Mediating role of laterality

Purpose: The aim of this research was to investigate the effect of the consequence memory training program on youth motor memory performance and to investigate the mediating role of laterality.Methods: The statistical sample of this study also includes 60 young women on the right and left hands that were selected based on inclusion and exclusion criteria and randomly divided into four groups. The tasks used were included the alternative serial reaction time task, the Wechsler memory scale, third edition, and the BackN working memory test. Subjects participated in pretest, acquisition test, immediate retention test and 48 hours later in delayed retention test.Results: Results showed that there are significant differences between the performances of motor memory in the pretest stage with each of the stages. Comparison of the groups in motor memory performance showed that the subjects of the lefthanded experimental groups had better motor memory performance in all stages than the subjects of the other groups. Conclusion: The results of the present study showed that the left individuals had better performance in motor memory, so it is suggested that trainers pay special attention to the issue of laterality for training and performance of motor skills.
