Context influences the FN400 recognition event-related potential

Task context dissociates the FN400 and the N400

“…Moreover, the recognition FN400 effect was not only topographically dissociable from the N400 effect in the pleasantness task but also from the (only marginally significant) N400 effect in the study phase, corroborating the dependency of the FN400 on episodic fluency attributions. Hence, our study adds to the existing evidence that the FN400 and the N400 can be topographically and functionally dissociated as has been shown by studies that contrasted recognition tests with priming manipulations (Bader & Mecklinger, 2017;Bridger et al, 2012;Woollams et al, 2008) or life-time familiarity judgments (Leynes & Mok, 2020). Importantly, we showed that this dissociation holds also for two situations in which exactly the same stimulus materials with the same old/new status are presented but only the tasks differ.…”

“…In line with this idea, the FN400 old/new effect is greater for rare than frequent stimuli (Bridger et al, 2014; Stenberg et al, 2009). Moreover, Leynes and Mok (2020) found a centro‐parietal N400 attenuation for (well‐known) name‐brand products compared to (unknown) off‐brand products in a life‐time familiarity test, in line with higher absolute familiarity for the former compared to the latter. A topographically distinct FN400, however, was found when the same name‐brand products had to be distinguished from new name‐brand products in a subsequent recognition test (see also Bridger et al, 2014, for a similar dissociation within a recognition test).…”

The default‐interventionist model underlies premise typicality weakening the premise diversity effect during category‐based induction: Event‐related potentials evidence

“…Familiarity results from a surprising difference between perceived and expected fluency. These models consistently suggested that top‐down processes impact FN400, indexing familiarity perception, which results from a discrepancy among task‐related previous expectations and stimuli‐related processing, with greater FN400 amplitudes for increased processing discrepancies (Leynes & Mok, 2020; Mecklinger & Bader, 2020). Diverse premises meet smaller processing discrepancies than non‐diverse premises because diverse premises support CBI more than non‐diverse premises (Feeney & Heit, 2011; Foster‐Hanson et al ., 2020; Heit et al ., 2005; Kalkstein et al ., 2020).…”

Using Event-Related Potentials to Evidence the Visual and Semantic Impact: A Pilot Study with N400 Effect and Food Packaging

“…Examples can be found of how product exposure or brand-relatedness [ 79 , 80 , 81 ] modulate the N400 effect and also how a product and its attributes such as color, material, or lighting paired with descriptive information such as attributes or descriptors trigger congruence or incongruence effects [ 82 , 83 , 84 , 85 ]. These examples have also shown emotional elements implied by the use of priming or visual targets that show products [ 86 , 87 , 88 ]. Furthermore, recent reference research has evidenced potency as a catalyst of the congruence effect, mainly incongruence, in the relationship between a product, brand, and object characteristics or tributes [ 81 , 82 , 88 ].…”

This relationship was found for the N400 effect where color, materials, or similar can provide a significant incongruence effect in poorly designed or poorly displayed items [ 47 , 84 , 85 ].…”
