Where this record's text came from. faceted 2026-08 by reading the locally held text (corpus-body); every evidence string verified as an exact substring of that text before merging. SOURCE-TEXT WARNING: the PDF-to-text extraction of this paper has lost most inter-word spaces, so the verbatim quotes are run-together strings (e.g. 'Primingisatypeofimplicit memory;...'). They are reproduced exactly as they appear in the file and all pass a substring check; they are NOT paraphrases and the spacing damage is the extractor's, not mine. The article body also opens with ~1,500 characters of stray reference-list text bled in from the preceding Science article on asbestos; I quoted nothing from that region. Claim type is 'mechanism' rather than 'existence' because the paper's contribution is the PRS account of WHY priming dissociates from explicit memory, not the demonstration that priming occurs. Replication status = 'contested' is grounded in the paper's own text: it explicitly reports that processing theorists dispute the memory-systems interpretation of the same data. FACETS WITHDRAWN: the text used was word spacing lost in extraction (mean token length 48); the quotes verified against that text but it is not this paper. Record left ungrounded rather than grounded in the wrong document. The extracted text begins with the tail of an unrelated preceding Science article (an asbestos reference list, lines 8-16) and contains a block of PDF-mangled watermark characters plus scrambled figure-caption fragments around Fig. 1; no quotes were taken from any of that material, only from the priming article's running prose. This is a theoretical review article, so 'method' is review even though it reports one previously unpublished-style summary of experiments (Yule's Q values around 0.90 for identical cues, dropping to zero for different cues) and a case study of patient K.C. Replication status is set to 'contested' because the paper itself describes an active dispute with processing theorists who deny that separate memory systems are needed, while simultaneously reporting that the dissociations themselves have been obtained across many labs, tasks and populations. Update, 18 September 2026: the three passages above were written in this order - the first faceting, the purge, and the re-faceting from a spaced copy. The purge's 'it is not this paper' was wrong: the copy it judged was this paper with its word spaces lost (the copy is kept in an internal file). Today's phenomenon and method, and the quotes for claim type, phenomenon and method, come from the re-faceting (claim type, 'mechanism', is the same in all three); research_question, contribution and replication status are older than both facetings, and neither replaced them - both facetings argued 'contested', and the record keeps 'replicated'. 2026-08-19 and 2026-08-25 schema-0.3 passes: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
The quality of the text these quotes were cut from. corrupt-text-layer (SECOND COPY ONLY): the web page we fetched has lost its inter-word spaces - space ratio 0.022 against 0.155 in an internal file, which is intact and is the copy every anchor resolves against. THE DAMAGE IS IN THE PUBLISHING ARTEFACT, NOT IN THE GROUNDING TEXT; a quality note that did not say so would accuse the wrong file. All 35 live quotes are cut from the grounding copy and are unaffected.
This record’s own method is review, and the tags below follow from that. A review’s findings, quantities and statistics are things stated IN this paper, and some of them report results obtained elsewhere. No tag on this page names a different author. Measured across every review in this corpus, 81% of a review’s tags carry no citation at all — most of them are the review speaking. The corpus does not adjudicate the rest: read an unmarked tag as a claim this paper makes, not necessarily one it made first.

phenomenonpriming (implicit memory)— “Priming is a nonconscious form of human memory, which is concerned with perceptual identification of words and objects and which has only recently been recognized as separate from other forms of memory or memory systems.”
claim-typemechanism— “We believe that priming and perceptual identification are expressions of a single perceptual representation system (PRS), which exists separately from but interacts closely with other memory systems (10, 11).”
method — evidence— “The evidence we have reviewed converges on the PRS hypothesis-that is, priming reflects the enhancement of the neural computations and correlated cognitive operations of the perceptual representation system, PRS.”
mechanismpriming reflects a distinct perceptual representation system (PRS) - a pre-semantic, implicit memory that operates without conscious recollection, separate from but interacting with episodic and semantic memory— “Priming is a type of implicit memory; it does not involve explicit or conscious recollection of any previous experiences”mechanisms[0]
extends the authors' own earlier priming article (reference 9), which conjectured an as yet little understood memory system— “In an early article on priming, we conjectured that the effects we had observed might "reflect the operation of some ... as yet little understood memory system" other than semantic or episodic memory [p. 341 in (9)].”claim_relations[0]
builds-on Warrington and Weiskrantz's experiments on learning in densely amnesic patients (reference 4)— “One of the triggers for the study of priming turned out to be experiments by Warrington and Weiskrantz (4) showing that densely amnesic patients, who were severely impaired in their ability to remember recently seen information, exhibited near-normal learning when they were tested by methods that tapped what we now know is priming.”claim_relations[1]
contradicts processing theories of priming that treat memory as a unitary cognitive system (reference 49)— “These processing theories are usually based on a limited domain of data, such as cognitive psychology experiments with normal subjects.”claim_relations[2]
senseTHE PAPER THAT MADE PRIMING A MEMORY SYSTEM, AND IT SAYS HOW RECENT THAT WAS: `Priming is a nonconscious form of human memory, which is concerned with perceptual identification of words and objects and which has only recently been recognized as separate from other forms of memory or memory systems.` Not an effect, not a task - a system. Most of this corpus inherits that framing without arguing for it; this is where it was argued, and the `only recently` is the authors dating their own claim— “Priming is a nonconscious form of human memory, which is concerned with perceptual identification of words and objects and which has only recently been recognized as separate from other forms of memory or memory systems”senses[0]
senseAND THE SPLIT INSIDE THE WORD, MADE IN 1990 BY THE PEOPLE WHO OWNED IT: `priming is an expression of a perceptual representation system that operates at a pre-semantic level ... Conceptual priming, however, seems to be based on the operations of semantic memory.` Two phenomena under one term, separated by naming the systems rather than the tasks. This is the one-name-many-concepts problem being SOLVED inside a discipline - and it is worth the corpus noting that the solution was to split the referent and keep the word, which is exactly what soil science and psychology have not done with `priming effect`— “Evidence is converging for the proposition that priming is an expression of a perceptual representation system that operates at a pre-semantic level; it emerges early in development, and access to it lacks the kind of flexibility characteristic of other cognitive memory systems. Conceptual priming, however, seems to be based on the operations…senses[1]
senseAND THE ARGUMENT FOR A NEW SYSTEM IS TAXONOMIC, NOT EXPERIMENTAL: `Priming resembles PROCEDURAL memory in that it enhances perceptual skills. It also resembles SEMANTIC memory in that it involves cognitive representations of the world.` A new system is established by showing it sits between two accepted ones and belongs to neither. That is why this paper is cited by records in this corpus that share no method with it - the claim is about how to carve the field, and a carving can be adopted by anyone— “Priming resembles procedural memory in that it enhances perceptual skills. It also resembles semantic memory in that it involves cognitive representations of the world”senses[2]
senseAND THE UNAWARENESS IS OF THE MEMORY, NOT OF THE STIMULUS - WHICH IS A DIFFERENT CLAIM FROM EVERY MASKED-PRIMING RECORD HERE: `A person perceiving a familiar object is not aware that what is perceived is as much an expression of memory as it is of perception.` dehaene1998, Finkbeiner2011 and hesselmann2016 all work to make the STIMULUS unavailable to report. Tulving and Schacter are saying the stimulus is seen perfectly well and its status as a memory is what goes unnoticed. Two senses of `nonconscious priming` that the corpus has been filing under one heading— “A person perceiving a familiar object is not aware that what is perceived is as much an expression of memory as it is of perception”senses[3]
controlthe materials built so that the target word could not be predicted either from the picture or from the first two words of the phrase — held — rules out the priming effect being ordinary predictability - if the target can be guessed from the context, a faster response measures guessing rather than implicit memory— “247 materials had been constructed in such a manner that the target was not predictable either from the picture or from the first two words of the phrase.”controls[0]
outcome (stated by the tagger, no quotation)control — heldcontrols[0]
replicationreplicated— “A large number of experiments showing such independence have been reported, involving different kinds of priming tasks and tests (16).”
limitationThe authors say the field's knowledge of priming is still slight because research is at an early stage.— “We still know relatively little about priming at this early stage of research.”limitations[0]
limitationThe neural substrates of priming are largely unknown, and the cited neuroimaging and lesion evidence supports only indirect inferences about the brain basis of priming; direct studies are missing.— “Although this evidence bears directly on the neural bases of perceptual identification of words and objects, it can support only indirect inferences concerning the anatomical or physiological underpinnings of priming.”limitations[1]
limitationDirect studies of the brain loci of priming have not been done.— “However, studies that examine the matter directly are currently lacking and badly needed.”limitations[2]
limitationThe prediction that patients with 'reading without semantics' should show robust word priming has not yet been tested directly; only indirect evidence from a single alexic patient is offered.limitations[3]
limitationThe authors concede that their PRS account does not explain conceptual (semantically driven) priming effects.limitations[4]
limitationLittle is known about the neural systems that mediate priming.

When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
