Mental representations are one of the most advanced aspects of human cognition and can affect the mental experience of ownership of each person's body. Based on this, the present study, which is a two-stage mixed research, after inducing three levels of social-cognitive factors (equivalent to the individual, higher level, lower level), explained and predicted the mental ownership of the body. Is. The statistical population of the research included the students of Payam Noor University in Tehran, from which 61 women and 47 men were selected by convenience sampling. The research tools included the artificial hand error test of Cohen and Botvinik (1998), the subjective report questionnaire of the experience of owning an artificial hand by Longo et al. (2008) and the 12-block computer program of Tamir and Thornton's three-dimensional mental model for implicit and explicit association of social cognition representations. Data analysis with Pearson's correlation test showed that only the correlation of hand error scores and social cognition components at the third (lower) level was significant. Also, the standard multiple regression analysis showed that in explaining hand error at the third (lower) level, based on obvious association; Disgust only (Beta = -1.52), and based on implicit association; Friendship (Beta = 0.63), disgust (Beta = -0.55), and satisfaction (Beta = 0.26) were able to predict artificial hand error, respectively. The obtained results indicate that the identification of people with those who get a lower social status in the subjective evaluations of the person can occur less often.

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.

Mental representations are to be considered as the most advanced aspects of human cognition and in addition to their own physical representations, representations of social cognition of others can also affect the mental experience of each person's ownership of their body. Accordingly, the present research as a quasi-experimental study based on repeated measures, was conducted in order to investigate the effect of social cognitive representation on the mental property of the body. The population of the study consisted of all Students of Payame Noor University of Tehran from which 61 females and 47 males were selected by convenience sampling. The research instruments included Cohen and Botvinick's (1998) Rubber Hand Illusion Test, and Longo, et al.'s (2008) Rubber Hand Ownership Experience Mental Report Questionnaire. Induction of representations of social cognition was based on the three-dimensional mental model of social cognition by Tamir and Thornton (2020). The collected data were analyzed by repeated measures analysis of variance using SPSS-22 software. According to the findings, the error score of the rubber hand was higher than the rubber hand with the color close to the body and green, which was defined in terms of the factors of the levels of the three-dimensional model of social cognition at the extreme level, and lower than the blue rubber hand, which was at extremely low levels of the mental three-dimensional model. The results indicated that in social relations, the identification of individuals with those who have gained a higher social status in mental evaluations can be more than those who have gained a lower social status in mental representations.

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.

Mind: An Introduction to Cognitive Sciences by Paul Thagard is a book in the field of cognitive science that covers almost all areas of this knowledge.Thagardsapproach in this book is to describe and evaluate the main theories of mental representation such as logic, rules, concepts, analogies, images, and connections. This book is translated by RāminGolshāie; and Samt Press published it in 1391. The author of the present paper intends to write a review on this translation. Regarding this, he firstly mentions its positive points, and then talks about the book problems along with some examples form the translation. He categorizes these problems in two groups of the content and structural problems.
