the effect of individuals’ perception of type of task on determination of contextual interference levels

the aim of this research was to determine the effect of contextual interference derived from self-regulation practice with regard to type of task on acquisition and retention of tracking tasks with an emphasis on meta-cognition hypotheses (cognition and meta-cognition phenomena). for this purpose, 24 right handed male and female students of yazd university (mean age: 22± 1.7) were selected via self-regulation questionnaire as high self-regulated subjects. they were randomly assigned to two different groups: simple tracking (n=12) or complex tracking (n=12). the method was quasi-experimental. the tracking tasks used in this study were designed by software whose aim was tracking with highest speed and lowest error. the movement time and movement error (click) as well as the number of pattern switches were assigned as scores in different groups. the subjects practiced 8 blocks of 16 trails per session; then, they participated one block of 16 trials in the immediate and delayed (after 72 hours) retention phases. the data were analyzed by anova with repeated measures and t test in acquisition phase and retention tests. results showed no significant difference between the two groups in two types of tasks in acquisition and immediate and delayed retention phases of movement time. a significant difference was observed in movement error in the acquisition phase (p
