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 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 purpose of the present study was to examine the effects of self – control modeling , that is presenting moded to learner whenever they asked for it, on learning a timing task.twenty four right handed subjects (12 males, 12 females, aged 19-20) voluntarily participated in the study and were assigned randomly to two groups of self – control and yoked.the task was pressing the keys number 1, 4...

The effects of observing a model and of providing a response rule on the-leran-ing,/itransfer, and retention of a dial-reading, numerical concept were studied in 144 third-graders. Different experimenters conducted the immediate learning procedures versus the measurements of retention. No extrinsic reinforcers were promised or dispensed. The children profited both from modeling and from rule-pr...

this study aims to better understand the effect of practice schedule and feedback providing types. in two separate experiments the contextual interference effect in bandwidth and self-control feedback conditions on relative and absolute timing learning was examined. in experiment i, the effect of contextual interference using bandwidth and self-control feedback on absolute timing learning (para...

the aim of the present study was to investigate the effects of various scheduled practices (self-regulated and non-self-regulated) on the acquisition, retention and transfer of simple and complex tracking tasks. 96 right-handed undergraduate students (age rang: 18-24 years old) volunteered to participate in this study (48 females, 48 males). these students participated in physical education cla...

the purpose of the present study was to investigate the effect of self-controlled (sc) and instructor-controlled (ic) feedbacks on the acquisition of dart motor skill using videotape feedback. for this purpose, 200 female volunteer students of university of tehran participated in this research. after the questioners had been filled out, 36 individuals were randomly selected from 152 qualified p...
