Richter's EEG study establishes a single, continuous, magnitude relationship:
prediction-error (PE) size at encoding — indexed by the P3 event-related
potential — predicts *how much* a consolidated long-term memory schema
updates after a 24-hour delay, with the effect concentrated when the material
is schema-*inconsistent*. In her own abstract: "PEs predicted the updating of
a schema after a 24-hour delay, especially when participants were faced with
inconsistent compared to consistent material," and "the P3 amplitude tracked
both the PE at the time of learning as well as the updating of the memory
schema in the inconsistent condition." Her framing: "similar neural
mechanisms underlie the updating of consolidated long-term memory schemas and
short-term belief structures."

**The premise correction the promotion carries.** The harvested topic asked
whether this paper marks P3 as distinguishing "schema tuning" from "schema
restructuring." It does not — that binary appears nowhere in the abstract or
in two independent secondary summaries. "Tuning/restructuring" belongs to the
separate [[entity-david-rumelhart|Rumelhart]]-Norman taxonomy ([[claim-schema-change-four-mode-taxonomy]]),
four decades older and EEG-free. This is the same artifact the vault caught in
the Linnainmaa-"Annales" venue error: a real citation fused to a
plausible-but-unsourced elaboration upstream. P3 measures PE *magnitude*, not
a *mode* of change.

Why the vault keeps it: PE-as-update-trigger is the mechanism under
[[claim-schema-change-four-mode-taxonomy]] ("each triggered by prediction
error") and the neural echo of the vault's own contradiction discipline —
inconsistent input is what drives schema change
([[claim-cognitive-conflict-prerequisite-for-restructuring]]). The
consistent/inconsistent asymmetry is the same shape as
[[question-consolidation-pass-vs-revisit-protocol]]'s reconciliation problem.
