Schrödinger's cat and mouse: An adapted thought experiment for the context of consciousness

Consciousness, at its simplest, represents awareness of self in relation to the outside world. This can be divided further into the reasoning and rationality of Access consciousness (A-C) versus the experiential and 'what it's like' of Phenomenal consciousness (P-C). A-C is directly measurable, using standard tests of cognition and memory. However, owing to the subjective nature of P-C, its direct testability remains problematic. We have previously derived indirect measures of P-C that incorporates a combination of subjective questions that are informed by objective dimensions of A-C. This battery of questions have shown sound proof of principle but have not yet been fully tested in the clinical space. As a bridge to clinical validation and in the challenge of a quantification gap, a thought experiment (TE) provides supporting evidence from the philosophy of science. We propose testing the foundational principles upon which operationalization of P-C questions has been designed through the prism of such a TE. We identified that a late-stage theory confirmation type of TE was appropriate for context. In the absence of suitable candidate TEs from cognitive science, we explored adaptation of a classical thought experiment from quantum physics. The 'Schrödinger's cat' TE was refined for purpose into a novel 'Schrödinger's cat and mouse' TE. Using this novel TE, our stated theories on consciousness, specifically P-C, and means of testing resonate with disorders of consciousness, not least delirium.
