Summary: The study found that individuals with a higher sense of ownership displayed greater moral identity, while high agency was associated with increased moral identity particularly when sense of power is high. Results regarding deception were less clear and may be related to the impact of COVID-19. The findings on moral identity could potentially inspire policies relying on changes in corporeal awareness to combat immorality.

Summary: The mental experience of our body has been extensively studied in various research fields. It is challenging to navigate and comprehend the relationships between different dimensions of bodily experiences due to the diversity of research approaches and conceptual frameworks. This narrative review proposes an integrative framework grounded in studies on consciousness and self-consciousness, providing a basis for evaluating findings on different aspects of bodily experiences.

Summary: The author suggests that people represent themselves in the same way as they represent other individuals, events, and objects, by binding codes representing the sensory consequences of being oneself into a Me-File. This concept could provide a useful basis for more specific and theoretically productive experiments.

Summary: The neurophysiological processes reflecting body illusions such as the rubber hand remain debated. This study recorded EEG responses in human participants and used multivariate classification to identify temporal markers that reliably differentiate the illusory state from non-illusion epochs after approximately 125 and 275 ms following stimulus onset.

Summary: Providing VR users with a 3D representation of their body enhances their sense of involvement. Previous research has shown that embodiment improves task performance, motivation, and motor learning. This study investigates the impact of joint limitations on reaching movements and finds that mismatched movements disrupt the sense of embodiment.

Summary: The study found that increasing the duration of tactile stimulation only affected proprioceptive drift (PD) and not subjective questionnaires, indicating that PD and questionnaires are not proxies for one another, but reflect separate underlying processes of the somatic Rubber Hand Illusion (RHI).

Summary: The term embodiment is widely used in prosthetics research but often lacks clear definition. This hinders the comparison of studies using embodiment as a metric and impedes the advancement of prosthetics research. By systematically reviewing the definitions of embodiment, we found that it is often conceptualized based on body representations or experimental phenomenology. Treating prosthetic embodiment as the combination of ownership and agency allows for quantifiable measurement. Recommendations on metrics for outcome comparisons were provided for further discussions in prosthetics research.

Summary: The concept of embodiment is popular in prosthetics research, but consensus on its exact definition and usage in an experimental framework is lacking. This article proposes a multi-dimensional framework for prosthetic embodiment based on the integration of volition and multi-sensory information, and suggests that the embodiment of prosthetic devices should be assessed in environments as close to daily life as possible.

Summary: This study explored the impact of sensory manipulation on robotic embodiment related to social cognition, showing that tactile induction has more generalized effects on ownership, location, and agency. Interestingly, the strength of positive social feelings towards the robot does not seem to be directly linked to the intensity of embodiment sensations.

Summary: The study explored the mediating role of pornography use between attachment insecurities and body image self-consciousness in a large sample of women. Results indicated a direct effect of anxious and avoidant attachment on body image self-consciousness in women, with only anxious attachment showing a mediating role of pornography use when in a romantic relationship.

Summary: The experience of the self as an embodied agent in the world is crucial for human consciousness, and it involves the Sense of Agency and Body Ownership. This study used the Moving Rubber Hand Illusion and MRI scanner to explore the relationship between Body Ownership and Sense of Agency in the human brain. By combining visuomotor and visuotactile stimulations and measuring online trial-by-trial fluctuations, the researchers were able to distinguish brain systems related to sensory stimulation and subjective judgments. The results showed strong interconnections between Body Ownership and Sense of Agency at both behavioral and neural levels, with convergence of multisensory processing in specific neural systems.

Summary: This study investigates whether humans can experience supernumerary limbs beyond their own body, and developed a paradigm for supernumerary hand illusion to address this question. The results demonstrate that a genuine illusion of owning two rubber hands can be elicited, and this supernumerary hand illusion can be isolated from the sense of ownership of a single rubber hand.

Summary: Studies have shown that sensory attenuation triggered by the own hand and by the embodied fake hand have similar behavioral and neurophysiological signatures, indicating that body ownership plays a crucial role in distinguishing the source of perceived sensations.

Summary: A growing body of research has shown that altering the sense of limb ownership is associated with changes in limb temperature. However, recent contradictory results suggest that the relationship between this physiological reaction and body ownership may not be as clear-cut as previously thought. This study investigated whether the lateralization of hand dominance affects the cooling of skin temperature during an ownership alteration illusion. The results showed that the cooling effect was stronger when the illusion was applied to the left hand compared to the right hand in right-handed individuals, providing evidence for a specific laterality effect in the physiological response to body ownership alteration.
