 "central_reading": "Filter theory (Trika kañcuka model) posits a categorical distinction between agency-limitation (kalā-kañcuka: limited creativity/power-to-effect) and knowledge-limitation (vidyā-kañcuka: limited knowledge/access-to-structure), mapping them as distinct limitation dimensions. Predictive processing treats both as variations in a single precision-weighting parameter — agency beliefs correspond to precision of action-outcome predictions, and knowledge beliefs to precision of sensory or perceptual predictions. A protocol that independently manipulates agency and knowledge while measuring a shared behavioural readout can distinguish categorical from graded accounts by testing whether the two manipulations produce qualitatively different signatures that cannot be reduced to a single precision continuum. This protocol is designed as a differential test between the filter/contraction candidate and the generative-model/interface candidate.",

   "text": "A within-subjects factorial experiment can distinguish the categorical-distinction prediction (filter theory) from the graded-continuum prediction (predictive processing) at the agency/knowledge boundary. Factor 1 (Agency): high vs low sense of agency over action outcomes, operationalised via intentional binding in a temporal estimation task under varying degrees of action-outcome contingency (75% vs 25% congruent feedback). Factor 2 (Knowledge): high vs low perceptual precision, operationalised via visual cue validity in a metacognitive confidence task (80% vs 55% valid cues). The shared behavioural readout is the coupling strength between objective performance and subjective confidence (metacognitive efficiency, meta-d′). Filter theory predicts an interaction: agency manipulation will shift the baseline sense-of-causality independently of metacognitive coupling, producing a main effect of Agency on intentional binding magnitude with no corresponding modulation of meta-d′, while Knowledge manipulation will primarily shift metacognitive efficiency. Predictive processing predicts that both manipulations modulate a unified precision parameter, producing additive effects on whichever readout indexes precision most sensitively (both should shift meta-d′ in the same direction), with no residual interaction requiring qualitatively distinct agency and knowledge dimensions.",

   "hetu": "The filter theory maps kalā-kañcuka (agency-limitation) and vidyā-kañcuka (knowledge-limitation) to categorically distinct limitation dimensions, predicting dissociable effects of agency and precision manipulations on intentional binding and metacognitive efficiency respectively, whereas PP predicts both resolve to a single precision parameter with additive effects.",
