Key takeaways

From the reading, NOTE-1434.

  • Transparency, defined. A transparent representation is “not experienced as” a representation; an opaque one is, “for example in pseudo-hallucinations or lucid dreams”; there is “a graded spectrum between transparency and opacity” (p. 2, note 2).
  • Identification follows transparency. “Because our conscious body model is transparent, that is, because it cannot introspectively be recognized as a model, we fully identify with its representational content” (p. 3).
  • A narrower MPS. Since a robust sense of self is reported where body representation is reduced to a point, self-identification may reduce to self-location, giving MPS as “transparent self-location in a spatiotemporal frame of reference” (Windt’s formulation, p. 7).
  • The prediction, and the test. “Transparent spatiotemporal self-location is necessary and sufficient for bringing about a minimal, consciously experienced sense of selfhood” (p. 14). The test is a case of phenomenally opaque self-location; the paper asks whether any is known, and reports none.
  • Evidence is second-hand. Out-of-body prevalence figures (Alvarado 2000, Wolfradt) and one dream report; the paper itself says the categories in those surveys are ambiguous.

Standing in the record

Filed on 2026-10-30 for THEORY-064, the self-model account, whose promote_when names exactly the phenomenological test this paper turns into a research question. It narrows the test to self-location and makes lucid, bodiless dreaming the place to look, but it reports no case either way. It carries no instruction for machine-learning practice.
