What was done
This narrative review synthesized experimental literature regarding the spatial, temporal, and semantic principles of crossmodal stimuli used to induce body ownership illusions (BOIs). The authors reviewed theoretical explanations of underlying mechanisms and proposed a conceptual framework based on Bayesian causal inference to explain how the nervous system integrates multisensory, sensorimotor, and semantic signals to infer body ownership, highlighting neural network models for future computational implementation.
What was found
The abstract reports no quantitative results, effect sizes, or sample numbers. It qualitatively outlines that specific multisensory conditions reliably induce the perception of artificial body parts or fake bodies as one's own, and that a Bayesian causal inference model can conceptually account for these experimental observations.
Why it matters
The paper synthesizes the crossmodal stimulus rules governing body ownership illusions and provides a unified Bayesian causal inference model for own-body perception research.
Limits
This is a narrative review and conceptual proposal containing no new empirical data, meta-analytic pooling, or formal computational simulations. The abstract does not report the number of studies reviewed or systematic search criteria.
