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. Claim type is 'existence' because the paper's demonstrated result is a dissociation (the cost is eliminated, the benefit is not); the two-mechanism reading is stated as an inference ('The present findings indicate that priming-induced costs and benefits in a picture-naming priming task are the product of at least two distinct mechanisms, one that is attention-dependent and mediates the cost, and another that is independent of attention and mediates the benefit.') and the response-competition explanation is explicitly offered only as a suggestion, so 'mechanism' would over-read it. Note also that one component of the result is a null (no attentional effect on the benefit; no cost under divided attention), so 'null-result' is a partial fit for half the finding. Experiment 2's amnesia result does not obviously square with the paper's own cited Keane et al. (2000, 2009) findings that amnesics sometimes fail to show costs, but the paper never states that as a contradiction, so no relation is recorded for it. 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.

phenomenonpriming-induced performance costs and benefits in picture naming— “The present study examined the effect of divided attention on priming-induced performance costs and benefits in a speeded picture-naming task.”
claim-typeexistence— “Experiment 1 shows that the costs, but not the benefits, are eliminated by division of attention at encoding.”
method — evidence— “In the implicit memory task, attention at encoding (full vs. divided) was manipulated between groups, and study condition (old vs. new vs. lure) was manipulated within groups.”
mechanismA lure picture activates the perceptually similar studied item as a competing incorrect response alongside the correct one, so naming requires selection among alternatives.— “By contrast, the lure condition (which elicits the cost) resembles production priming tasks in that it entails response competition at test: Because participants have studied a picture that is perceptually similar to the test cue, it is likely that the test cue elicits activation of that (incorrect) response, as well as the correct (but…mechanisms[0]
mechanismBecause only the cost involves response competition at test, only the cost depends on attention at encoding, in line with the identification-production account.— “Thus, the absence of an attentional effect for the benefit, and the presence of such an effect for the cost, may be linked to the absence or presence of response competition at test, respectively, in accord with the identification-production account.”mechanisms[1]
contradicts unitary-source accounts of priming costs and benefits (Rouder, Ratcliff & McKoon, 2000; Marsolek, 2008)— “The present finding that costs and benefits in priming are differentially affected by divided attention therefore poses a challenge to both theories insofar as it suggests that the source of these two effects, or the process by which they are manifested, is not identical.”claim_relations[0]
replicates Gabrieli et al. (1999) on divided attention not reducing the picture-naming priming benefit— “This aspect of our results is consistent with prior findings in a picture-naming task ( Gabrieli, et al., 1999 ).”claim_relations[1]
replicates Cave & Squire (1992) and Verfaellie et al. (1996) on normal picture-naming priming benefits in amnesia— “Prior studies have shown that the priming-induced performance benefit in picture naming is normal in amnesia ( Cave & Squire, 1992 ; Verfaellie, Gabrieli, Vaidya, Croce, & Reminger, 1996 ), and we expected to replicate that finding in Experiment 2.”claim_relations[2]
sensePRIMING WITH THE SIGN REVERSED, and a field-level gap named in the abstract: the literature has focused EXCLUSIVELY on priming effects that are beneficial and has OVERLOOKED those that are costly, `wherein performance is harmed by prior exposure to task stimuli`. Nearly every other priming record in this corpus reports a facilitation. If `priming` is defined as an influence of prior exposure rather than as a benefit, then half the phenomenon has gone unstudied because of what the word suggests— “This work, however, has focused exclusively on priming effects that are beneficial in nature (wherein performance is enhanced by prior exposure to task stimuli), and has overlooked priming effects that are costly in nature (wherein performance is harmed by prior exposure to task stimuli)”senses[0]
sensecost and benefit as a SYMMETRIC PAIR of operationalisations - both are response times against the same NEW baseline, in the same task, from the same study phase: benefit = faster to OLD than to new, cost = slower to LURE than to new. Because the two share a baseline and differ only in the relation between studied and test item (identical versus merely similar), a dissociation between them cannot be explained by task or by measure— “The performance benefit in this task is manifested as faster response times in the test phase to old than to new pictures, and the cost as slower response times to lure than to new pictures”senses[1]
sensethe amnesia control, and it is chosen for the ALTERNATIVE IT KILLS. Dividing attention damages explicit memory as well, so eliminating the cost that way leaves open that the cost was explicit all along. Amnesic participants have no explicit memory to lose and the costs are INTACT - so the Experiment 1 result cannot be an artifact of reduced explicit memory. A population used as a control condition rather than as a subject of study— “Experiment 2 shows that the costs (as well as the benefits) in this task are intact in amnesic participants, demonstrating that the elimination of the cost in the divided attention condition in Experiment 1 was not an artifact of the reduced availability of explicit memory in that condition”senses[2]
senseattention required WHERE A SELECTION MUST BE MADE - the paper's account of why one effect needs attention and the other does not is not about strength or depth but about whether the test cue leaves a CHOICE. The lure activates a wrong response alongside the right one; the old item points at a single correct response. Offered as a suggestion (`We suggest`, `may be linked`), and weighted here as one— “Thus, the absence of an attentional effect for the benefit, and the presence of such an effect for the cost, may be linked to the absence or presence of response competition at test, respectively, in accord with the identification-production account”senses[3]
controlthree FILLER PICTURES resembling none of the critical stimuli placed at the beginning and end of the study list — held — rules out that memory for the critical items is inflated or depressed by primacy and recency— “Three filler items (pictures that did not resemble any of the critical stimuli) appeared at the beginning and end of the list to blunt any primacy and recency effects on later memory for the stimuli.”controls[0]
controlitems counterbalanced across participants so each pair appeared equally often in the old, lure and new conditions — held — rules out that a condition effect is an item effect - that the old, lure and new sets simply contain different pictures— “Across participants, items were counterbalanced across conditions such that each pair appeared equally often in the old, lure, and new conditions.”controls[1]
controlwhich member of each pair became the target and which the mate was decided at random — held — rules out that the target items are systematically more memorable than their mates— “(See sample stimuli in Figure 1 .) We randomly designated one member of each pair as the “target” item (which was the item that was always presented in the test phase) and the other member as the “mate.” The 30 pairs were divided into three lists of 10 for purposes of counterbalancing across the old, new and lure conditions.”controls[2]

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.
