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. Source is OCR'd PDF text with words broken across line ends (e.g. 'com parisons', 'Mar cel', 'unequivo cally'). Every quote above was chosen to avoid those splits and was machine-checked as an exact substring; several otherwise apt sentences were passed over solely because transcribing an OCR break exactly is error-prone. The paper's critique of Holender (1986) and Marcel (1983) is a substantial part of the argument but was NOT recorded as a claim_relation, because the cleanly quotable sentences describe those positions rather than stating this paper's own relation to them, and the ones that do state it are OCR-broken. Replication status is 'contested' because the paper reports its familiarity/duration direction agreeing with one body of work and directly opposing another. Claim type is 'method' (the proposed relative-sensitivity framework) even though Experiments 3-4 also deliver a null/critique result against Avant and Thieman. 2026-08-14 and 2026-08-15 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 WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below.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 6 concept tags on this paper, all 6 are grounded in a quoted sentence.
dissociation paradigm measure of awareness direct measures exhaustiveness assumption null sensitivity indirect measure Instructing an observer to respond on a given stimulus dimension makes them exploit whatever conscious information about that dimension exists, which is why a direct task can never be beaten by an indirect one on conscious information. Apparent direct/indirect dissociations can be manufactured by measuring the two indexes on different stimulus states and displays, so the gap reflects unequal discrimination difficulty rather than unconscious perception. indirect measure of perception exclusiveness assumption filled-duration illusion exposure duration stimulus familiarity (word vs. nonword) proportion of "longer" responses t-test ANOVA p-value mean mean propor tions 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/10.3758/bf03207490. 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 2 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.

what this limits: any claim that a direct discrimination reflects intentional responding: the paper states an observer's intentions cannot be directly observed or measured
limitations[5]1.0the tagger's words
limitationsThe paper's own diagnosis is that decades of experimental work could not settle the question because the field had no agreed measure of the thing being denied. An empirical programme is stalled by a definitional gap, and the remedy offered is not a better definition but a weaker assumption - an ordering between two sensitivities rather than a claim that either instrument is complete.

differs in: WHETHER THE EXHAUSTIVENESS ASSUMPTION IS MADE. Reading a null on a direct measure as an absence of awareness 'can be true ONLY IF it is also assumed that direct measures provide AN EXHAUSTIVE MEASURE of conscious perceptual experience. Quotation withheld, given conscious perceptual experience' · strength of the relation: 0.9 · note: A NULL MEASUREMENT MEANS ABSENCE ONLY IF THE INSTRUMENT IS EXHAUSTIVE, and the assumption is usually implicit - the paper calls it 'another IMPLICIT assumption underlying many recent…'. This is the 1988 psychology statement of the problem that a verifier cannot report absence. Audit 2026-09-28: DOUBTFUL - read against its full span and kept, but the span discusses the ASSUMPTION that direct measures are exhaustive measures of awareness; operationalised-as is loose.

differs in: WHETHER THE TWO ARE MEASURED UNDER COMPARABLE CONDITIONS. Avant and Thieman (1985) claimed an indirect measure was MORE sensitive than a direct one; 'CONTRARY TO THIS CLAIM, WHEN DIRECT AND INDIRECT INDEXES ARE MEASURED UNDER COMPARABLE CONDITIONS', the indirect measure is LESS sensitive. The ordering of the two instruments reverses on the comparability of the conditions, not on the instruments · strength of the relation: 0.85 · note: THE PUBLISHED CLAIM AND ITS REVERSAL USE THE SAME TWO MEASURES. What changed is that they were put on comparable footing - the same lesson as measuring candidates within one run rather than across runs.
