Where this record's text came from. faceted 2026-08 by reading the locally held text (xml); every evidence string verified as an exact substring of that text before merging. Replication status set to untested because the paper reports no external test of its own null claim; note the paper is itself a failed replication of Brodbeck (1997) and internally failed to replicate its own Experiment 5 effect in Experiment 6. The key dissociation is anchored by: 'These results indicate that the monkeys did remember the primed images at the time they were classifying the masked version of those images, but that remembering the image did not facilitate classification.' Claim_type is null-result rather than critique because the paper's own data, not argument, carry the contribution. 2026-08-17 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.
How to read this page. The article itself is not reproduced here — this paper is not cleared for redistribution, so what follows is the tag layer alone. The evidence sentences are withheld with the article. The table at the foot lists every tag the record carries; each row names the facet it belongs to, and the whose words column says whether the tag records the paper's own wording or the tagger's sentence about the paper. Every tag links to each other paper in the corpus carrying it. The machine-readable edition of the same thing is the TEI file beside this one, where the tags live in standOff, and the article is at its publisher via the link below. 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 WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below.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 An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason.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.

Tags on this paper

Every tag the record carries, each linking to every other paper in the corpus that carries it. A tag appears here whether or not its words occur in the article — the spans below are only the ones a sentence in this paper licenses. Of the 7 concept tags on this paper, all 7 are grounded in a quoted sentence. All carry the tagger's gloss of what the term means in this paper, which is not something the article can license.
perceptual priming priming explicit memory recognition classification repetition suppression search image The visual processing that supports recognition is encapsulated from the processing that supports classification, so remembering an image cannot feed forward to help classify a degraded version of it. Pigeons and monkeys classify by different routes — local features versus global shape — which is offered as the explanation for why priming appeared in pigeons but not here. specific searching image perceptual closure accuracy latency classification accuracy image quality (color, grayscale, line drawings) category control images t-test Paired t-tests ... one-sample t-tests arcsine transformation arcsine transformed significance level (alpha), two-tailed testing effect size (Cohen's d) p-value median the median time from onset of the sample Type I error a Type I error behavioural-experiment

The paper

The full text is not reproduced here. This article is not cleared for redistribution, so the page carries the tag layer only. Its evidence sentences are withheld; the grounding status remains with each tag, and the article itself is at https://doi.org/10.1016/j.beproc.2012.08.005. The reading view exists for the papers whose licence permits it.

Relations on this page carry a quotation for the claim. Where a relation was separately evidenced — and so tested against the vocabulary for its type — the row says so; none of 4 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.

sensespriming as IMPLICIT - named by the paper as the critical feature of the theories it is testing, and stated as a double requirement: subjects identify primed material better AND cannot explicitly remember it. The effect is defined partly by a FAILURE that has to accompany it, which is why a study finding memory for the primes is testing something the definition cares about

sensespriming defined by a PROPERTY LIST rather than by a mechanism - automatic, effortless, unconscious, neuroanatomically separate from sophisticated forms of memory such as episodic memory. Every item is a contrast with something else, and it is precisely this shape of definition that licenses the leap to evolutionary age: a capacity that needs none of the expensive machinery is assumed to have come first

sensesthe PHYLOGENETIC ASSUMPTION, named as an assumption in the abstract: priming is `commonly thought, with little evidence, to be widely distributed phylogenetically`. The paper's target is not a finding but a belief its field holds without having tested it - and the only prior nonhuman evidence it can find is one study in pigeons

senses[2]0.95the tagger's words
sensessearch image versus perceptual priming - a neighbouring concept separated by two stated measurements rather than by definition: the search image is SHORT LIVED and is DIMINISHED BY DIVIDED ATTENTION, so it is classed as short-term ATTENTIONAL priming rather than the long-term PERCEPTUAL priming seen in humans. Two literatures using one word, told apart by duration and by whether attention matters

senses`priming` and `perceptual priming` are used at DIFFERENT GRAIN in different parts of the argument, and the split is systematic rather than casual: where the paper reasons about memory SYSTEMS - dissociation from explicit memory, survival in amnesia, evolutionary age - it writes bare `priming`; where it describes the visual effect it measures, and where it fences that effect off from the search image, it writes `perceptual priming`. The general term carries the theory and the specific term carries the experiment

sensesa null defended rather than reported - the paper argues its own absence of evidence is not absence of power, on three separate grounds: priming is routinely seen in SINGLE human subjects, the pigeon result that motivated the study used FEWER subjects than this one, and the same animals demonstrably remembered the primes. The last is the one that matters, because it rules out the animals not having encoded the images at all

differs in: DURATION AND ATTENTIONAL DEPENDENCE - the search image is short lived and is diminished by divided attention, which is why the paper files it as short-term attentional priming rather than long-term perceptual priming · strength of the relation: 0.9 · note: The paper's own phrase is 'similar to, but distinct from', and it does not leave the distinction as an assertion: both differentiating properties are cited to experiments.

differs in: WHETHER IT SURVIVES AMNESIA AND WHICH NEURAL SYSTEM CARRIES IT - the separation is the definition rather than a finding about it, which is what makes this record's null result awkward for the theory · strength of the relation: 0.9 · note: Recorded because the dissociation is doing definitional work: priming is IDENTIFIED by being separable from explicit memory. A monkey that recognises the primes but shows no priming is a dissociation running the other way.

strength of the relation: 0.7 · note: Weight 0.7 - the LOWEST on this record, and deliberately. The paper reports this as a theorised mechanism it is about to find fault with: the neural signature is present in monkeys and the behavioural effect is not. Recorded as the literature's claim, not as this paper's.

The paper's last word on it is 'presents a puzzle', and the weight says so.
