Abstract

Objective: The embodied self refers to the sense of self intertwined with the physical body and its experiences, which is impaired in schizophrenia. Comprehension of metaphors that are cognitive tools to help the comprehension of abstract ideas is also impaired in patients with schizophrenia. The Conceptual Metaphor Theory (CMT) links embodied experiences and metaphors to boundaries, indicating that these disruptions may lead to difficulties in understanding boundaries in schizophrenia. This study explores the role of embodied self and metaphor comprehension in predicting boundary concept comprehension in patients with schizophrenia.

Method: This study employed a cross-sectional correlational design to examine the relationships among variables. The current study recruited 85 Male patients who were diagnosed with schizophrenia (mean age = 47.84 years, SD = 7.58) through a convenience sampling method. All participants completed the Embodied Sense of Self scale, the Montreal Evaluation of Communication (MEC) Metaphor subtest, and a researcher-developed questionnaire assessing comprehension of the boundary concept. Multiple linear regression analyses were applied to assess the associations between the embodied self, metaphor comprehension, and understanding of the boundary concept.

Results: The suggested Model predicts 50% of the total variance (P < 0.01, R2 = 0.50). Metaphor comprehension predicts boundary concept understanding (β = 0.67, P ≤ 0.01, R2 = 0.50), while the embodied self (β = -0.13, P = 0.1, R2 = 0.50) does not.

Conclusion: Our findings indicate that impairments in metaphor comprehension are significantly related to the understanding of boundary concepts in schizophrenia, while no such relationship was observed with the embodied self. These results highlight the role of metaphorical cognitions in boundary perception, potentially extending to issues with the self-other boundary and representing relations of self-other boundary disturbances and Metaphorical cognition.
