Where this record's text came from. faceted 2026-08 by reading the locally held text (pdftext); every evidence string verified as an exact substring of that text before merging. Replication status is 'untested' in the sense of independent external replication; the paper does report internal replication twice, verbatim: "Experiment 2 replicates the dissociation between the priming and matching tasks observed in Experiment 1." claim type 'mechanism' was chosen over 'existence' because the causal statement (local flanker-to-background contrast drives priming) is the paper's substantive claim; the abstract also frames it as a demonstrated dissociation. Source is pdftext with heavy OCR/ligature damage (e.g. "(cid:120)(cid:129)", "Par-rr adiso", stray duplicated letters); all quotes reproduce these artifacts exactly so the substring check passes. 2026-08-16, 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.
Some quotes on this page contain (cid:NN). The PDF this text was extracted from encodes 10 characters in a way that names no letter, so the extractor could not say what they were. The quotes keep them because a quote is reproduced exactly or it proves nothing — the marks are the source’s, not the tagging’s.

phenomenonresponse priming by luminance flankers— “Response priming by luminance flankers depends neither on the actual physical luminances of the flankers nor on their subjective brightness, as assessed in a psychophysical matching task; instead, it seems to depend exclusively on the local luminance contrast of the flankers to their immediate background.”
claim-typemechanism— “Indeed, the experiment clearly shows that priming effects reverse in exactly those conditions in which the flankers’ local contrast to the background reverses, indicating that it is, indeed, local flanker-to-background contrast that drove the priming effect.”
method — evidence— “They were instructed to keep their eyes on the fixation point and to respond as quickly and correctly as possible, pressing the key on the side where the brighter target was presented.”
mechanismThe feedforward sweeps triggered in turn by flankers and targets still carry only local contrast information, so motor activation is driven by raw local contrast while conscious brightness is settled later by recurrent interactions.— “this view suggests that the feedforward sweeps successively triggered by the flankers and targets are still dominated by local contrast signals.”mechanisms[0]
mechanismConscious lightness and brightness are computed later, by recurrent processing that trails the initial feedforward wave.— “The conscious perception of lightness and brightness will be determined later in processing, probably as the result of recurrent interactions trailing behind the initial processing wave”mechanisms[1]
mechanismResponse priming accesses a stimulus representation that precedes lightness constancy, i.e. one that has not yet discounted illumination.— “We adopt the less radical view that response priming reflects a stimulus representation that is earlier and less elaborate than the one underlying conscious vision and, consequently, deficient in lightness constancy.”mechanisms[2]
mechanismPlacing the high-luminance flanker on the lighted segment turns it into a local decrement (and the low-luminance flanker on the shadowed segment into a local increment), which is what inverts the priming sign.— “In the attenuation condition, however, the high-luminance flanker was a local decrement because it appeared on an even more luminant background”mechanisms[3]
builds-on Moore and Brown (2001), visual search under a dark transparent filter— “Our conclusions are in agreement with a study by Moore and Brown (2001), in which visual search for highluminance and low-luminance targets was performed under conditions in which parts of the display seemed to be watched through a dark transparent filter.”claim_relations[0]
contradicts physiological studies reporting that subjective lightness is signalled early in the hierarchy (MacEvoy & Paradiso, 2001; Rossi & Paradiso, 1999; Rossi, Rittenhouse, & Paradiso, 1996)— “This conclusion might seem to conflict with some physiological studies showing that subjective lightness is signaled early in the processing hierarchy, such that the responses of many cells in the primary visual cortex (V1) and even some in the lateral geniculate nucleus are modulated by a simultaneous contrast illusion (MacEvoy & Par-rr…claim_relations[1]
contradicts Breitmeyer, Ro, and Singhal (2004), the proposal that response priming is based on raw physical stimulus characteristics rather than perceived color; the authors explicitly adopt a "less radical view" in the next sentence— “Breitmeyer, Ro, and Singhal (2004; Breitmeyer, Ö(cid:120)(cid:129) men, & Chen, 2004) have proposed that response priming is based on raw physical stimulus characteristics, such as the distribution of wavelength information, instead of perceived color. We adopt the less radical view that response priming reflects a stimulus representation…claim_relations[2]
builds-on the rapid-chase model of response priming (Schmidt et al., 2006; Schmidt & Schmidt, 2009)— “In the framework of the rapid-chase model of response priming (Schmidt et al., 2006; Schmidt & Schmidt, 2009), this view suggests that the feedforward sweeps successively triggered by the flankers and targets are still dominated by local contrast signals.”claim_relations[3]
senseA QUALITATIVE DISSOCIATION, AND IT IS A REVERSAL RATHER THAN AN ATTENUATION: `These findings indicate a qualitative dissociation between the subjective brightness of the stimuli and their propensity for priming a motor response: Even though one stimulus can appear brighter than another, it can trigger responses as if it were darker.` Not a smaller effect in one condition - the sign flips, while the observer's own brightness match goes the other way. A quantitative dissociation can be argued about with a power analysis; a reversal cannot— “These findings indicate a qualitative dissociation between the subjective brightness of the stimuli and their propensity for priming a motor response: Even though one stimulus can appear brighter than another, it can trigger responses as if it were darker”senses[0]
senseAND THE CONTROL THAT MAKES THIS DIFFERENT IN KIND FROM EVERY OTHER DISSOCIATION IN THIS CORPUS: `Note that this dissociation makes no use of visual masking or brief stimulus presentations of any kind: It is obtained even though the presented stimuli are all in plain view, and it relies solely on characteristic differences in processing dynamics between the priming and matching tasks.` dehaene1998 flashes a numeral for 43 ms between masks; marcel1983, holcomb2005 and Finkbeiner2011 all argue about whether the prime was seen. This paper lets the observer look straight at it. So the gap is not between seen and unseen but between two live representations of one visible stimulus - which is a different claim, needing none of the machinery the awareness literature spends its credibility on— “Note that this dissociation makes no use of visual masking or brief stimulus presentations of any kind: It is obtained even though the presented stimuli are all in plain view, and it relies solely on characteristic differences in processing dynamics”senses[1]
senseTHE CLAIM IS A TRIPLE NEGATIVE THAT NAMES ITS WINNER: `Response priming by luminance flankers depends neither on the actual physical luminances of the flankers nor on their subjective brightness, as assessed in a psychophysical matching task; instead, it seems to depend exclusively on the local luminance contrast of the flankers to their immediate background.` The two excluded candidates are the physical variable and the perceptual variable - between them, everything anyone would have guessed - and each was excluded by a measurement rather than by an argument. The third is named, and it is a property of the stimulus's relation to its own neighbourhood— “Response priming by luminance flankers depends neither on the actual physical luminances of the flankers nor on their subjective brightness, as assessed in a psychophysical matching task; instead, it seems to depend exclusively on the local luminance contrast of the flankers to their immediate background”senses[2]
senseAND THE INFERENCE IS CAREFULLY PARTIAL: `If priming effects are in systematic disagreement with the flankers' perceived brightness values, this suggests that at least some aspects of lightness constancy are absent from the response activation process.` `at least some aspects` and `suggests` are both in the quote, and they are the difference between this and a claim that the motor pathway is pre-constancy. The illusion used here IS a consequence of lightness constancy - the authors say so - so its failure to reach the response is evidence about one pathway, not a map of the visual system— “If priming effects are in systematic disagreement with the flankers’ perceived brightness values, this suggests that at least some aspects of lightness constancy are absent from the response activation process”senses[3]
controla whole experiment (Experiment 3) built to test the local-contrast-sign account — held — rules out that responses are driven by the local contrast sign of the target rather than by the primed response— “Experiment 3 was designed to rule out responses to the target on the basis of local contrast sign.”controls[0]
evidence status noteBreitmeyer, Ro, and Singhal (2004), the proposal that response priming is based on raw physical stimulus characteristics rather than perceived color; the authors explicitly adopt a "less radical view" in the next sentence — 2026-08-16: FAILED GLYPH INSIDE THIS QUOTE. Two failed glyphs inside a surname: the staged text reads "Breitmeyer, Ö(cid:120)(cid:129) men, & Chen, 2004". The author is Haluk Ogmen (O-with-diaeresis, g-with-breve), and the extraction lost both diacritic characters and left the raw font codes with a stray space. This affects only the CITED NAME, not the claim: the sentence's assertion about response priming and raw physical stimulus characteristics is intact. The quote is an exact substring of the staged file; the file is incomplete here, not the tag.— “Breitmeyer, Ro, and Singhal (2004; Breitmeyer, Ö(cid:120)(cid:129) men, & Chen, 2004) have proposed that response priming is based on raw physical stimulus characteristics, such as the distribution of wavelength information, instead of perceived color. We adopt the less radical view that response priming reflects a stimulus representation…claim_relations[2]

notelocal luminance contrast —causes→ response priming — 'EXCLUSIVELY' IS IN THE QUOTE AND IT IS THE WHOLE CLAIM. Two rival causes are named and excluded in the same sentence - physical luminance and subjective brightness - so this is not 'X is associated with Y' but 'X and not the two things you would have guessed'. Weight 0.95: the general discussion's opening sentence, resting on a systematic variation of the illusion rather than on one contrast. 'increases' means more local contrast in the priming direction yields more priming, and the reversal condition is the same relation with the contrast sign flipped.concept_edges[0]

noteresponse priming —distinct-from→ subjective brightness — A REVERSAL, NOT AN ATTENUATION, AND THAT IS WHY THIS EARNS 0.95. 'distinct-from' usually records that two concepts are not the same thing; here the quote shows them moving in OPPOSITE directions on the same stimulus - one flanker appears brighter and primes as if darker. And the second sense is what makes it valuable: no masking, no brief presentation, the stimuli in plain view. Every other dissociation in this corpus separates a seen thing from an unseen thing; this separates two representations of a thing the observer is looking at.

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.
