The minimal self refers to the self as an actor and owner of sensations, feelings and actions and hence to an embodied self whose sensory and motor experiences provide the basis for bodily self-awareness and for the sense of agency and body ownership. Crucially, perceiving, sensing and acting as a minimal but embodied self has been closely associated with sensorimotor and somatosensory information processing, i.e., processes operating primarily at a prereflective and prelinguistic level. However, this does not mean that in humans, processes associated with the bodily minimal self and processes associated with language and cognition would be unrelated. Behavioral and neuroscientific research in healthy adults accumulated empirical evidence against the disembodiment of human language and cognition. In line with this evidence, the present project proposal will investigate (1) how perceiving, feeling and acting as a bodily minimal self interact with the processing of linguistic representations of the self and (2) how the processing of linguistic self-representations addressing the self as an agent (“I”) and owner (“my”) of subjective experience influences feelings, judgements and illusions of agency and ownership during somatosensory tactile stimulation, during voluntary motor control and during the rubber hand and enfacement illusions. Pronouns will include personal and possessive first person pronouns referring to the self as subject and agent (“I”, “you” vs. “he”/”she”) or as object and owner (“my”, “yours” vs. (“his”/”her”) of experience. Pronouns will be presented visually and acoustically to explore effects between linguistic and bodily somatosensory and sensorimotor processing across modalities. Methodologically, EEG-ERP measures, peripheral-physiological (e.g., startle-reflex modulation, heart rate, finger-/hand temperature, skin conductance) as well as behavioral and self-report measures of agency and ownership will be used to investigate how and at which stages of information processing self-referential processing of linguistic cues interacts with bodily somatosensory and sensorimotor experience, with feelings and judgements of agency and body ownership and with the experience of body ownership illusions including hand and face. The primary focus is on healthy adults because in healthy adults a stable sense of self - both with regard to language and bodily experience - is already developed. Individuals from individualistic and collectivistic societies will be investigated to prove the dependence/independence from cultural and linguistic norms. Individual differences in body ownership illusion and in self-other overlap will be additionally controlled by baseline measurements. The project will close important explanatory gaps in the scientific understanding of the relationship between bodily processes, linguistic representations of the self and the subjective experience of agency and body ownership.

最小自我指的是作为演员和感觉、感觉和行动的所有者的自我，因此是一个具身的自我，其感觉和运动经验为身体的自我意识、代理感和身体所有权提供了基础。至关重要的是，感知、感知和行动作为一个最小但具体化的自我，与感觉运动和体感信息处理密切相关，即主要在前反思和前语言水平上运作的过程。然而，这并不意味着在人类中，与身体最小自我相关的过程与与语言和认知相关的过程是不相关的。对健康成人的行为和神经科学研究积累了反对人类语言和认知分离的经验证据。根据这一证据，本项目提案将研究(1)作为身体最小自我的感知、感觉和行动如何与自我的语言表征的处理相互作用；(2)在体感触觉刺激期间，将自我作为主观经验的代理人（“我”）和所有者（“我的”）的语言自我表征的处理如何影响代理和所有权的感觉、判断和幻觉。在自主运动控制期间，在橡胶手和表演幻觉期间。代词将包括人称和所有格第一人称代词，指的是自我作为主体和代理人（“我”，“你”对“他”/“她”）或作为客体和所有者(“我的”，“你的”对（“他的”/“她”）的经验。代词将在视觉和听觉上呈现，以探索语言和身体的躯体感觉和感觉运动处理之间的影响。方法上，脑电图- erp测量、外周生理测量（例如，惊吓反射调节、心率、手指/手温度、皮肤电导）以及代理和所有权的行为和自我报告测量将被用于研究信息处理的自我参照处理语言线索如何以及在哪些阶段与身体体感和感觉运动经验相互作用。对代理和身体所有权的感觉和判断以及对身体所有权的体验包括手和脸的幻觉。主要的重点是健康的成年人，因为健康的成年人在语言和身体经验方面已经形成了稳定的自我意识。将调查来自个人主义和集体主义社会的个人，以证明对文化和语言规范的依赖/独立。身体所有权错觉和自我-他人重叠的个体差异将由基线测量额外控制。该项目将填补对身体过程、自我的语言表征、代理和身体所有权的主观经验之间关系的科学理解中的重要解释空白。
