Human has always been interested in thinking about nature of self, and knowing its dimensions. In fact, different information is forming psychological and embodied representations through cognitive processes. The result of these representations is two types of mental sense of self: body self-awareness, and psychological self-awareness. Sometimes, the real representation makes mistake and, under certain circumstances, experiences an artificial hand as a real one. This study was designed and conducted to predicting rubber hand illusion based on embodied and psychological self-awareness. The statistical population consisted of all male and female students living in Tehran. A sample of 167 people (96 females and 71 males) were selected by convenience sampling method. Research instruments included the self-consciousness scale (Fenigstein et al., 1975), and embodied sense of self scale (Asai et al., 2016) as well as performing Rubber hand illusion testing. Data were analyzed by using SPSS and AMOS software. The results of path analysis showed that the dimensions of psychological and embodied self-awareness have a negative and significant direct relationship with rubber hand illusion. Also private self-awareness mediated by embodied ownership and agency awareness; and public self-awareness mediated by embodied ownership awareness are negatively and indirectly related to rubber hand illusion. These results indicate the role of different dimensions of consciousness in body representations and have created new insights into the boundaries of knowledge related to these concepts.

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.
