The findings hold only for the early (under 100 ms) time range studied; priming in other time ranges appears to follow different laws. about this quote: QUOTE RECOVERED FROM THE PAPER'S OWN CHARACTERS. The recorded quote was LETTERS-ONLY IDENTICAL to this stretch of the staged text but not an exact substring of it - spaces, hyphens, ligature glyphs or mathematical operators differed, so it could never anchor. This is the file's own text between the same two letters: not produced by a rule about the damage, copied out of the file. Round-trip checked (the recovered span is letters-only equal to the original) and length-checked. The text as originally recorded is kept in evidence as extracted. Quotation withheld because this record is not cleared for redistribution. The proposed accumulator model is not the only account compatible with the data; other saturating or leaky models might also fit. about this quote: QUOTE RECOVERED FROM THE PAPER'S OWN CHARACTERS.

Quotation withheld because this record is not cleared for redistribution. the slope prediction from the mean-process approximation was re-derived by MONTE CARLO SIMULATION of the stochastic process eliminates: that the analytic result is an artefact of the mean-process approximation and does not hold for the stochastic process it approximates · outcome (stated by the tagger, no quotation): held Quotation withheld because this record is not cleared for redistribution. priming time courses were compared under two different masking types eliminates: that masking and priming reflect the SAME underlying process - a dissociation between the two time courses cannot be produced by a single mechanism · outcome (stated by the tagger, no quotation): held Quotation withheld because this record is not cleared for redistribution. response priming response priming Quotation withheld because this record is not cleared for redistribution. metacontrast masking metacontrast masking Quotation withheld because this record is not cleared for redistribution. action priming action priming Quotation withheld because this record is not cleared for redistribution. visual awareness visual awareness Quotation withheld because this record is not cleared for redistribution. SOA SOA Quotation withheld because this record is not cleared for redistribution. priming priming Quotation withheld because this record is not cleared for redistribution. recognition accuracy recognition accuracy Quotation withheld because this record is not cleared for redistribution. THE DOUBLE DISSOCIATION ITSELF, and it is two CURVES rather than two conditions: `within the SOA range from 42 to 98 ms: the amount of priming INCREASED, but recognition accuracy DETERIORATED with SOA`. No level of invisibility is asserted anywhere - the argument is carried entirely by the opposite slopes, which is the criterion Schmidt2011 later proposed as a replacement for requiring zero sensitivity Quotation withheld because this record is not cleared for redistribution. `different temporal laws` - the general form of the claim, and it is a statement about SHAPES rather than about magnitudes: conscious perception and unconscious behavioural effects of the same masked stimuli do not merely differ in size, they are governed by different functions of time. Seventh record this sitting where a time course is the load-bearing variable, and the first where two time courses ARE the finding Quotation withheld because this record is not cleared for redistribution. SUBLIMINAL IN WHICH RESPECT - a precision most records in this corpus do not make: `prime stimuli were not subliminal in the sense that their presence or absence could not be detected, but the critical prime feature remained perfectly invisible`. Something was plainly there to be seen; the attribute that did the priming was not. `Subliminal` is a predicate of a FEATURE here, not of a stimulus, and the difference decides what the effect is evidence for Quotation withheld because this record is not cleared for redistribution. the priming time course is INDIFFERENT to whether the prime could be reported: `Quotation withheld` The masking function changes shape - type A to type B - and the priming function does not follow it. That is a stronger result than a difference in size at one delay, because it survives a change in the shape of the other curve Quotation withheld because this record is not cleared for redistribution. extends → the neural accumulator model of Hanes and Schall about this quote: QUOTE RECOVERED FROM THE PAPER'S OWN CHARACTERS.

Quotation withheld because this record is not cleared for redistribution. action priming —distinct-from→ visual awareness action priming visual awareness differs in: THEIR TIME COURSES - measured under the same conditions, on the same stimuli, and found to obey different temporal laws. Over 42 to 98 ms priming rises while recognition falls, so neither can be a noisier reading of the other · strength of the relation: 0.95 · note: THE PAPER'S RESULT, and the empirical basis for the criterion Schmidt2011 proposes eight years later. Confidence 0.95 - the contrast is the study's design, stated in its own summary of what it did. Quotation withheld because this record is not cleared for redistribution. SOA —causes→ priming SOA priming direction on the measure: increases · strength of the relation: 0.9 · note: Half of the dissociation. Recorded separately from the visibility half so that the two directions are queryable independently - a corpus that stored only 'there was a double dissociation' could not answer which way each curve went. Quotation withheld because this record is not cleared for redistribution. SOA —causes→ recognition accuracy SOA recognition accuracy direction on the measure: reduces · strength of the relation: 0.9 · note: The other half, and the reason the pair is a dissociation rather than a correlation: the SAME manipulation moves the two measures in OPPOSITE directions over the same interval. Quotation withheld because this record is not cleared for redistribution. masked response priming increased with SOA from 42 to 98 ms while prime recognition fell Quotation withheld because this record is not cleared for redistribution. priming can occur without the prime being consciously seen Quotation withheld because this record is not cleared for redistribution. ANOVA ANOVA Quotation withheld because this record is not cleared for redistribution. standard-error standard-error Quotation withheld because this record is not cleared for redistribution.
