Summary: It is important to understand how the body representation can be modified, and this study used the Rubber Hand Illusion (RHI) to investigate its temporal dynamics. The feeling of Ownership is established within the first 19 seconds of stimulation and continues to grow, but at a slower pace. The feeling of Ownership disappears within 66 seconds after the stimulation ends, highlighting the malleability of body self-consciousness.

Summary: Virtual reality allows for fast and controllable experimental body image settings, with EEG oscillatory activities providing insights into human multisensory integration processes. However, EEG data recorded in VR environments may be vulnerable to noise, posing challenges for measurement and analysis. The study highlights differences in brain activities between real and VR settings, emphasizing the need to consider these differences in investigating bodily self-perception using VR.

Summary: The impact of altered gravitational conditions on the sense of body ownership is a significant area of research. Through the study of unconventional gravity conditions, it has been found that the relative weights of visual, proprioceptive, and vestibular inputs change, favoring vision and increasing susceptibility to the rubber hand illusion.

Summary: The rubber hand illusion is a perceptual illusion that can also occur with delayed visual feedback, causing proprioceptive drift. The study found that hand ownership and localization are caused by distinct multisensory integration processes.

Summary: The study found that the experience of the Rubber Hand Illusion is directly related to empathy and self-esteem, while disembodiment and physical sensation are unrelated to individual personality traits. The study provides substantial evidence to use the embodiment scale as a standard questionnaire for future Rubber Hand Illusion studies, and the correlations with personality traits suggest that the embodiment induced by the illusion deeply integrates with the complexity of the individuals and their differences.

Summary: This study explains the subjective experience during rubber hand illusions using integrated information theory (IIT). The study found that the integrity of the whole system decreases during the illusion, while the integrity of its subsystems increases. The results suggest that IIT can explain the general tendency of ownership illusions and individual differences in subjective experience during the illusions.

Summary: This study suggests that the subjective intensity of tactile stimulation experienced across different conditions modulates the strength of proprioceptive drift during the Rubber Hand Illusion, indicating that different types of tactile stimulation influence the illusion of body ownership perception.

Summary: In this study, the researchers attempted to replicate the reduction in MEP amplitude associated with the rubber hand illusion (RHI) and identify the components of the illusion that might explain these changes. Despite participants reporting the presence of the illusion and shifts in perceived real hand position towards the fake limb, no reduction in MEP amplitude was observed.

Summary: The study showed that manipulating body ownership through the rubber hand illusion has little impact on basic motor control, as subjective sensations of rubber hand ownership did not convincingly correlate with kinematic variables according to experimental results.

Summary: This study analyzes a research on the rubber hand illusion, suggesting that hypnotic suggestibility and expectations have some influence on the illusion, but the main factor is multisensory stimulation. Synchronous stimulation results in a stronger illusion and greater proprioceptive drift compared to asynchronous stimulation. Expectations have a very small effect on the illusion ratings.

Summary: Enabling sensory feedback in limb prostheses may not be effective for all amputees, as evidenced by the failure to induce the rubber hand illusion in participants with transhumeral amputation; in a study with 30 able-bodied subjects, tapping and stroking were found to equally induce ownership sensations in two-thirds of the participants; participants immune to the rubber hand illusion were still able to experience ownership over prosthetic limbs in daily life, highlighting a significant limitation of the RHI paradigm.

Summary: The study found that in the rubber hand illusion, participants who reported feeling ownership also tended to report touch referral, showing a moderately strong positive relationship between the two. Touch referral was often reported more strongly and frequently than ownership, indicating implications for the experimental paradigm.

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: Research shows that people can experience an illusion that a mechanical grabber, which looks scarcely like a hand, is part of their body. This indicates that artificial objects can become embodied even though they bear little visual resemblance to the hand.

Summary: This study aimed to induce the third-person perspective full body illusion (3PP-FBI) in stroke patients using virtual reality. The results showed that synchronous visual-tactile stimulation of a single body part was sufficient to elicit 3PP-FBI in stroke patients, forming a sense of ownership over the entire virtual body. Furthermore, the intensity of 3PP-FBI was stronger when the back was stimulated compared to stimulating the impaired upper limb.

Summary: A new method was proposed to evaluate participant choices in virtual reality applications, using a reinforcement learning agent to suggest possible factor changes and converging on a consistent factor configuration. The experiment showed that participants preferred using teleportation for navigation, full-body representation, responsiveness of virtual human characters, and realistic rendering.

Summary: In virtual reality, the Golden Rule can be considered a paradigm for promoting prosocial behavior by creating an illusion of ownership over a virtual body. This phenomenon, known as the Golden Rule Embodiment Paradigm (GREP), has been utilized to influence implicit attitudes and enhance helping behavior in studies conducted within VR environments.

Summary: Domestic violence has long-term negative consequences on children. In this study, men with a history of partner aggression and a control group were placed in virtual reality as a child's perspective to witness a scene of domestic violence. The study found that the experience mainly affected the recognition of angry facial expressions and physiological responses during explicit violent events. This research demonstrates the potential of virtual reality in the rehabilitation and neuropsychological assessment of males with a history of domestic violence.

Summary: This study created a virtual reality version of a 1983 performance by Dire Straits and carried out two studies to understand participants' responses. The findings revealed that the presence and behavior of the virtual audience elicited negative sentiment, which dominated the overall sentiment over the virtual band. These results underscore the importance of achieving plausibility in virtual reality and highlight the significance of co-design and sentiment analysis in VR scenarios.

Summary: Change blindness refers to the phenomenon where people fail to notice dramatic changes in their visual environment. In virtual reality, there are differences in the perception of changes in one's own virtual body compared to the body of another person. A study conducted in virtual reality showed that a majority of participants did not notice changes in their own face or the face of the virtual instructor. This suggests that people tend to make inferences about their visual surroundings without paying attention to details, and changes in one's own body may impact self-representation.
