The aim of this study was to investigate the role of the errorless, errorful and random practice schedules on the acquisition and learning of relative timing in a motor task. 51 male students (age: 22±4 years old) were selected and randomly assigned to four groups (control, errorful, errorless, and random). This study was carried out in five phases: pretest (PRT), acquisition (ACQ), 10-min retention and transfer and 24-hour retention and transfer. In the acquisition phase, a timing task with three different difficulty levels (simple, moderate, and difficult) was practiced in three sessions of 45 trials with feedback by experimental groups. In order to analyze the data, a mixed-design analysis of variance model with repeated measures on each variable was used in the acquisition and retention phases. The one-way analysis of variance (ANOVA) was used in the other phases. The findings of relative timing showed no significant differences among the groups in the pretest (P˃0.05). Additionally, in retention and transfer tests, errorless group had better performance than errorful, random and control groups (P≤0.05). Errorless group performed better than the random and errorful groups in 24-hour transfer test of the secondary task (P≤0.05). These results showed that practice in errorless conditions leads to a better learning of the task and its generalization to new conditions that are consistent with the implicit learning and reinvestment theories

The aim of the present study was to examine the effect of combined observational and shadow practices on learning dart throwing skill. 60 female high school students (17-19 years old) who volunteered to participate in this study were selected and randomly assigned to 5 groups after pretest: observational, shadow, physical, combined (observational-shadow) and the control. During the acquisition phase, the practice groups practiced 60 trials of dart throwing skill based on the specific instructions for each group. 10 minutes after the acquisition phase, immediate retention/transfer tests were conducted and after 24 hours of detraining, delayed transfer/ retention tests were carried out. ANOVA with repeated measures (P=0.05) revealed that practice groups had significantly better performances than the control group (P>0.05). Also, physical and combined groups had significantly better performances than the observational and shadow groups (P<0.05). The combined group enjoyed learning equal to physical practice (P<0.05). Overall, the results indicated that combined observation and shadow practices resulted in learning equal to physical practice. These findings suggest that as this practice method can be applied anytime and anywhere with minimum requirements, it can reduce the educational time and costs and even it can be replaced by physical practice under specific circumstances.
