Motor imagery is one of the cognitive aspects of the tasks which is investigated as a factor affecting performance in many situations. Also, another cognitive dimension of tasks that researchers believe to play an important role in motor control and performance is mental representation. This study aimed to determine the relationship between motor imagery ability and mental representation structure in basketball free throw.

The design of this research was correlational and a convenient method of sampling was used. In this study, the Motor Imagery Questionnaire-Revised and Mental Representation Software were used as tools. The motor imagery ability of 60 female basketball players was measured and 10 participants with the highest (mean age: 16.3±2.05 years) and 10 participants with the lowest (mean age: 20.3±4.9 years) imagery ability were selected. Then, their mental representation was measured using mental representation software. The relationship between motor imagery ability and mental representation was analyzed using correlational analysis.

The results showed that the group with the highest motor imagery ability had a more structured mental representation which was more similar to that of criterion mental representation. Also, the results showed that there was a positive relationship between imagery and mental representation structure scores in both groups.

These results were interpreted using the perceptual-cognitive approach. Also, these results were considered a piece of evidence for the top-down process of imagery. Achieving these results indicate that psychological skills training accompanied by technical skills training will have a critical contribution for the athletes to success in sports.

This study was aimed to address the effect of motor imagery and action observation on the mental representation and accuracy of basketball free throw. For this purpose, 40 participants were divided into four groups including: imagery, observation, mixed, and control. Participants practiced the basketball free throw for one week (100 trials per day) according to their grouping. One week after the last session of training, a retention test was performed. Movement accuracy and the structure of mental representation were measured. Results of movement accuracy showed that the mixed group had a higher accuracy than other groups. Also, the observation group performed more accurate than imagery group. In the mental representation measure, the mixed group had a more structured mental representation than other groups. In addition, the mental representation of imagery group was more structured than observation group. These findings were interpreted according to the different underlying of these practice types

This study was aimed to compare the effect of practice with high, low, and increasing interference on accuracy and mental representation of basketball free throw. For this purpose, 30 novice participants were randomly divided into random, blocked, and increasing groups. The participants practiced the basketball free throw from different distances (3/96, 4/57, and 5.18 meter) for three consecutive days-three blocks each day and each block included 30 trials- according to the given grouping and practice order. Three days after the last training session retention and transfer tests were performed. Results showed that the increasing group had higher accuracy than the other two groups. The results during the transfer test were similar to the retention test. The results for the mental representation measure showed that the increasing group had a more structured mental representation that two other groups and this mental representation were more similar to the mental representation of the skilled participants. These results were interpreted according to the efficient processing of the information and also according to the challenge point framework

The purpose of this study was to investigate changes in mental representation in golf putting task due to random and blocked practice. Thirty participants were divided into random, blocked and control groups. First, the initial mental representation level of participants was measured and they performed 18 trials as retention. Then, they practiced the intended task for six consecutive days. A week after the last practice session their final mental representation level was measured and performed 18 trials as retention test. Results showed that random group had more errors than blocked group during acquisition, but performed more accurate than this group during retention. In addition, it was showed that random group has a more structured mental representation than the blocked group and this representation is more like the skilled participants.

The purpose of this study was to investigate the effect of routine introduction, imagery and mixed methods on performance and mental representation of volleyball overhand float-serve. To this purpose, 40 girls were randomly divided into routine introduction, imagery, mixed and control groups. After a pre- test, participants practiced the task for seven consecutive days (each day 5 blocks 10 trials each) according to their grouping. One week after the last practice session, participants performed the post- test. Results showed that mixed group performed better than two other experimental groups. Also, routine introduction group outperformed than imagery group. However, in mental representation measure, the imagery group had a more structured mental representation than two other groups. In addition, the mixed group had a more structured mental representation than routine introduction group. These results were discussed in relation to the underlying mechanisms of these methods of practice.
