0 spans located by searching the stored text for the quote's exact words, allowing any whitespace between them existence Quotation withheld because this record is not cleared for redistribution. cross-modal semantic priming (picture-word) Quotation withheld because this record is not cleared for redistribution. fmri fmri Quotation withheld because this record is not cleared for redistribution. mechanisms Presentation of a prime activates its concept, and that activation spreads automatically along associative pathways in the semantic network to related concepts, so the related target is already pre-activated when it appears. Quotation withheld because this record is not cleared for redistribution. mechanisms The haemodynamic decrease for related pairs arises because pre-activation lowers the demand on semantic memory retrieval and selection, so less neural work is needed than for unrelated pairs. Quotation withheld because this record is not cleared for redistribution. mechanisms The shared right fronto-temporal deactivation is attributed to the easier semantic processing of associatively related concepts, an ease that does not depend on which modality delivered the prime. Quotation withheld because this record is not cleared for redistribution. The sample was restricted to male subjects, so gender effects on the reported lateralisation and language processing are untested here. Quotation withheld because this record is not cleared for redistribution. Only artifact (man-made object) concepts were used, so the findings may not extend to natural/living concepts or to manipulable versus non-manipulable relations. Quotation withheld because this record is not cleared for redistribution. a PRE-TEST established that the word pairs really were strongly related eliminates: that a null or weak priming effect is a failure of the materials rather than of the hypothesis · outcome (stated by the tagger, no quotation): held Quotation withheld because this record is not cleared for redistribution. four pseudo-randomised versions of the experiment counterbalanced across subjects eliminates: that the conditions systematically influence one another through their order · outcome (stated by the tagger, no quotation): held Quotation withheld because this record is not cleared for redistribution. semantic priming semantic priming Quotation withheld because this record is not cleared for redistribution. cross‐modal cross‐modal Quotation withheld because this record is not cleared for redistribution. response suppression response suppression Quotation withheld because this record is not cleared for redistribution. lexical decision lexical decision Quotation withheld because this record is not cleared for redistribution. unimodal unimodal Quotation withheld because this record is not cleared for redistribution. A NULL WHERE THE DESIGN EXPECTED A DIFFERENCE: `Quotation withheld` A picture priming a word behaves like a word priming a word. Set beside Chen2018, tagged earlier tonight - which separated two cross-modal primes by their time courses - this says the modality BOUNDARY itself costs nothing, while what crosses it still can Quotation withheld because this record is not cleared for redistribution. THE SHORT SOA IS A CONTROL AND THE ALTERNATIVE IS NAMED: `In order to avoid strategic influence or expectancy which can affect priming‐specific patterns of activation ... we wanted to use fast, automatic, implicit processing, i.e., semantic priming with an short stimulus onset asynchrony.` The SOA is not a parameter, it is a fence - it makes strategy impossible rather than unlikely. Eighth record this sitting where a time course is load-bearing, and the first where it is used as a CONTROL rather than reported as a result Quotation withheld because this record is not cleared for redistribution. `response suppression` DEFINED BY SCOPE rather than by mechanism: it is `a special form of BOLD response deactivation, response enhancement a special form of BOLD activation in the context of semantic priming experiments in an fMRI SETTING`. The definition carries its own boundary - the same neural word means this only here - which is exactly the move this corpus exists to record Quotation withheld because this record is not cleared for redistribution. A SAMPLING DECISION WITH ITS REASON, AND ITS COST: `Quotation withheld` The rationale is stated and is statistical rather than theoretical - homogeneity bought at the price of generalising to half the population. Worth a row because the trade is made explicit rather than left to be noticed by a reader Quotation withheld because this record is not cleared for redistribution. builds-on → Caramazza et al. [1990] (Organized Unitary Conceptual Hypothesis) Quotation withheld because this record is not cleared for redistribution. contradicts → Paivio, 1991 (multiple semantic systems) Quotation withheld because this record is not cleared for redistribution. replicates → Caramazza et al., 1990; Vandenberghe et al., 1996 Quotation withheld because this record is not cleared for redistribution. cross‐modal —distinct-from→ unimodal cross‐modal unimodal differs in: WHERE IN THE BRAIN, NOT HOW MUCH - both produce a behavioural priming effect and the comparison of the two revealed NO behavioural difference, while the neural suppression sits in bilateral fronto-parietal regions for unimodal and in the right inferior frontal gyrus for cross-modal · strength of the relation: 0.85 · note: Weighted 0.85 rather than higher because the distinction is NEUROANATOMICAL ONLY - behaviourally the paper reports no difference at all, and an edge read without that qualifier would overstate the separation. The null has its own sense row. Audit 2026-09-28: DOUBTFUL - read against its span and kept, but the span reports priming for both cross-modal and unimodal pairs; distinct-from is loose.

A significant behavioural priming effect was obtained in both the picture-word and the word-word conditions. Quotation withheld because this record is not cleared for redistribution. The size of the cross-modal priming effect was statistically indistinguishable from the unimodal one. Quotation withheld because this record is not cleared for redistribution. Unimodal word-word priming produced response suppression across bilateral fronto-parietal cortex. Quotation withheld because this record is not cleared for redistribution. Cross-modal picture-word priming produced response suppression confined to the right inferior frontal gyrus. Quotation withheld because this record is not cleared for redistribution. The direct contrast between the two modalities yielded no significant modality-specific clusters. Quotation withheld because this record is not cleared for redistribution. The authors conclude their data support an amodal semantic system rather than multiple semantic systems.
