Synopsis: This peer-reviewed research, printed in Frontiers in Psychology, explores how top-down interpretation – our prior experiences, expectations, and biases – impacts physique possession in digital actuality. Performed by researchers at Hiroshima College, the research used a full-body phantasm (FBI) in VR to check whether or not imagining a digital physique in ache would disrupt the sense of possession. Findings point out that individuals with increased depersonalization tendencies struggled extra with feeling linked to the digital physique, particularly when instructed to understand it as experiencing ache. This analysis presents precious insights into situations like depersonalization-derealization dysfunction, which impacts physique notion, and will contribute to scientific interventions for these experiencing a disconnection from their bodily selves, together with people with disabilities and seniors who might have altered sensory processing – Disabled World (DW).
Introduction
The manipulation of top-down interpretation as one’s symptomatic physique reduces the sense of physique possession.
A research from Hiroshima College discovered that when folks have been instructed to think about their digital our bodies in ache, their brains resisted the phantasm of possession. Their findings might present insights into why some folks might wrestle with feeling linked to their very own our bodies, significantly in contexts involving depersonalization or unfavorable bodily states.
Focus
The sense of physique possession – the sensation that our physique belongs to us – is essential in distinguishing ourselves from objects and responding to threats. Researchers research it utilizing methods just like the rubber hand phantasm (RHI) and full-body phantasm (FBI), by which a person is in some way influenced to establish with possession of a faux or digital physique. To discover how physique possession will be disrupted, researchers take a look at whether or not top-down elements – the place earlier information, recollections, and beliefs form how we understand and interpret new info or stimuli – weaken the phantasm when individuals are requested to establish with a digital physique in a unfavorable bodily state.
Researchers printed their leads to Frontiers in Psychology in December 2024.
“Utilizing the full-body phantasm in digital actuality – the place folks start to really feel a digital physique as their very own – we investigated how decoding the digital physique as one’s personal physique, whereas in a unfavorable bodily state, impacts this phantasm. This analysis can presumably relate to depersonalization, a situation the place folks wrestle to really feel their physique as their very own,” mentioned Kazuki Yamamoto, researcher and writer of the research.
Contributors have been instructed to view a digital physique from the again utilizing a digital actuality (VR) headset and picture it as their very own. Contributors would watch the digital physique have their again stroked whereas their very own bodily physique was stroked additionally which efficiently illicited the phantasm. It is a technique of utilizing bottom-up elements, which begins with an exterior stimulus to combine visual-tactile info, and is a well-tested strategy to efficiently affect the FBI.

To check the impact of top-down elements, the identical plan of action was instructed with the addition of figuring out with the digital physique as their very own in a unfavorable bodily state (feeling stomach ache). After the participant watches their digital physique being stroked alongside their again, a worry stimulus is offered within the type of a knife driving into the digital physique’s again. The worry response is measured utilizing a skin-conductance response and the diploma of conductance measures is then associated to how strongly the participant is figuring out with their digital physique.
One of many details of this research is utilizing top-down elements, that are expectation or biases on what one thing ought to really feel like primarily based on prior expertise or interactions, to find out if these also can affect a way of physique possession.
Outcomes indicated that the full-body phantasm was inhibited when requested to view the digital physique as their very own with stomach ache, and the upper the diploma of depersonalization tendencies inside the individuals resulted in a decrease diploma of FBI.
Researchers recommend this could possibly be because of a number of elements, one in all which being the manipulation of utilizing top-down elements. One other suggestion is that the individuals might need had issue perceiving the unfavorable bodily signs, subsequently that they had issue totally establishing the connection of “the digital physique is my physique” which is vital for the phantasm to happen.
Given the findings of the research, extra analysis will be carried out to completely perceive why an inhibition of the phantasm occurred.
“Whereas we noticed this inhibitory impact, additional analysis is required to find out whether or not it was particularly because of the unfavorable interpretation or to variations between precise and digital physique states,” mentioned Takashi Nakao, researcher and writer of the research.
The inspiration supplied by this research and subsequent research can help in scientific intervention for these affected by disturbed physique possession, akin to people with depersonalization-derealization dysfunction. This work can enhance these people’ sense of physique possession, which might drastically enhance lives, not just for security functions but additionally sensory and notion functions.

Since its basis in 1949, Hiroshima College has striven to develop into one of the vital distinguished and complete universities in Japan for the promotion and growth of scholarship and schooling. Consisting of 12 faculties for undergraduate stage and 5 graduate faculties, starting from pure sciences to humanities and social sciences, the college has grown into one of the vital distinguished complete analysis universities in Japan.
Editorial Word: By demonstrating how cognitive interpretation can weaken physique possession illusions, this research opens new pathways for understanding and treating situations that have an effect on bodily self-awareness. Future analysis can refine these findings to higher assist people with depersonalization signs, power ache, or sensory integration challenges. The implications prolong past psychology, with potential purposes in VR remedy, rehabilitation, and assistive applied sciences that improve bodily notion for these with neurological or sensory impairments – Disabled World (DW).
