the present research examined the effect of different feedbacks such as blocked, random and specialized to the most difficult part of a task on acquisition and retention of badminton high service. at first, 10 expert badminton players performed 10 trial high service and 10 with probe technique to determine the most difficult part of the high service. the difference between the two scores define...

Age may limit the effect of contextual interference, but the accurate effect of age on contextual interference is not completely identified. Therefore, the purpose of the study was the effect of contextual interference practice orders on acquisition and learning of badminton skills of 45 female students aged from 10 to 12. Participants were randomly assigned to one of the three groups of bloc...

the aim of this study was to compare the effects of random and blocked practices with respect to the changes in generalized motor program (gmp) and parameter on acquisition, retention and transfer of table tennis service. for this purpose, 32 subjects were randomly assigned to four groups (8 subjects each group). in the first two groups, gmp changed with blocked and random arrangements while in...

this research was performed to compare the effect of various levels of contextual interference (blocked, random and increasing practice schedules) on acquisition, retention and transfer of movement time error and cursor error in a complex motor – perceptual task. for this purpose, 30 female students (age range of 11 – 13 years) participated in a pretest (3 parts of 12 trials) and based on their...

this research was performed to monitor the effects of different practice schedules on learning and transfer of generalized motor program and timing parameter in a serial task. for this purpose, 80 participants (age: 19-23 years) voluntarily participated in this research and then they were divided randomly into 4 groups: blocked, random, blocked-random and random-blocked. this test included perf...

contextual interference is defined as interference in performance and learning that arise from practicing one task in the context of other tasks. transitional practice is a kind of practice sequence that starts out with trials of large blocks; then moves to smaller random blocks, and eventually finishes with complete randomization. the aim of this study was to investigate the effect of ‘transit...

this study aimed at investigating the effect of blocked, incremental systematic and random contextual interferences on acquisition, retention and transfer of volleyball skills based on changes in a generalized motor program. in fact, this study was conducted to answer this question that whether regular increment of contextual interference level is more effective on learning volleyball service s...

the aim of the present study was to investigate the effect of contextual interference on balance of mentally retarded people. for this purpose, 40 educable and mentally retarded boys in qazvin city (mean age 24.45 ± 3.120) were randomly divided into two groups: blocked and random practice. after the pretest, given their practice arrangement, subjects in each group performed their workout for 4 ...

BACKGROUND When learning multiple tasks, blocked or random training schedules may be used. We assessed the effects of blocked and random schedules on the acquisition and retention of laparoscopic skills. METHODS Thirty-six laparoscopic novices were randomized to practice laparoscopic tasks using blocked, random, or no additional training. Participants performed immediate post-tests, followed ...
