For this purpose, 60 right-handed older adults were randomly divided into six groups of blocked-similar, learner-adapted-similar, random-similar, blocked-dissimilar, learner-adapted-dissimilar, and random-dissimilar. Sequential timing was used as the task, and the intrinsic motivation questionnaire was used for measuring individuals' motivation. The learner-adapted practice was included performing the task in a combination of blocked, serial, and random orders according to error number in each block. The results showed that the learner-adapted practice significantly outperformed than other practice schedules in motivation and motor learning measures in similar and dissimilar conditions. Also, the random schedule resulted in superior performance than the blocked schedule in similar and dissimilar conditions. These findings were discussed according to the challenge point framework.
Utilizing the Variability of Practice in Physical Execution, Action Observation, and Motor Imagery: Similar or Dissimilar Mechanisms?

Accordingly, applying a high-level psychological variable (variability of practice) should have a similar effect on all three modes. To test this theory, a total of 90 right-handed students participated in this study and were randomly divided into variable versus constant groups in three practice conditions, including physical, observational, and imagery. After a pretest (10 random trials of the putting task), the participants completed 50 practice trials. The groups performed/observed/imagined the task in the variable (different distances to different goals) or constant (fixed distance and goal) practice conditions. Also, there was an extra variable group in the physical and observational conditions, deprived of watching the feedback from the action. The participants completed a retention test 24 hr after the training. The effect of practice variability was obs...

Thirty participants were randomly assigned to random practice, blocked practice, and no-practice groups. First, we measured novice golfers’ initial mental representation levels and required them to perform 18 putting trials as a pre-test. We then asked random and blocked groups to practice in accordance with their group assignment for six consecutive days (10 blocks each day, 18 trials each). A week after the last practice session, we re-measured all participants’ final mental representation levels and required them to perform 18 putting trials to evaluate learning retention through practice. While those engaged in the random practice method putted more poorly during acquisition (i.e., practice) than those in blocked practice, the random practice group experienced more accurate retention during the final putting trials, and they showed a ...

Twelve skilled basketball players and 12 novices (mean age = 25.4 years, SD = 4.3) were divided into four groups (skilled constant, skilled variable, novice constant, and novice variable). After a pretest, participants practiced free throw action. The variable groups threw the ball over an obstacle of varying heights on each trial in random order, whereas the obstacle’s height was fixed for the constant groups. After 7 and 14 consecutive days of practice, participants performed two posttests with constant and variable distances from the basket. The results showed that practicing different solutions of a task did not affect the performance of skilled players but had an immediate negative effect on the performance of novice players. Learning a complex task is the result of learning task-related parameters, and practice variability can create a ...

Participants practiced a sequenced timing task in random, algorithmic, or blocked schedules in both similar and dissimilar task difficulty conditions, with task difficulty defined by absolute timing goals (in ms) that were either close to each other (1350, 1500, 1650) or far from each other (1050, 1500, 1950), respectively. We assessed older participants’ timing accuracy in these conditions, during acquisition and delayed retention learning, using the frontal alpha asymmetry index, recorded during practice, to measure motivation. On the accuracy measure in delayed retention, the algorithm practice schedule (in both similar and dissimilar conditions) was associated with significantly more accurate performance than random and blocked practice schedules. Also during delayed retention and in both task difficulty conditions, ...
