Comparison the effect of increasing and decreasing contextual interference with the change of parameter on the anticipation timing coincidence task learning

The purpose of this study was comparison effect of increasing and decreasing contextual interference with the change parameter on the anticipation timing coincidence task learning and error detection capability. 40 boy students (23 – 25 years old) participated in this study (10 students in each group). Subjects don’t know any thing about respective task. Different levels of contextual interference (block, random, increasing and decreasing) were comared with same motor program and different parameter. Task includes anticipation timing coinsident whit different speeds (change parameter). After the training, subjects participated in retention and transfer tests and also their absolute error were assessed. One way Anova, repeated measurement and toky tests were used for data analysis (SPSS 16). There was different significant between absolut error block group and other groups in acquisition stage (p<0.05) but there was not different significant between groups in retention and transfer stages. Results support the hypothesis Magill and Hall (1990). They believed that contextual interferenc effect was not observed with change parameter.
