“…This N400 component also responded to norm violation, but it was observed only for Chinese. Previous work has shown that the frontal N400 might be functionally distinct from the central-parietal N400 (25). In particular, the frontal N400 is implicated in the evaluation of the appropriateness of different human actions, such as the meaning of hand postures (26), appropriateness of tool use (27), and semantic anticipation of action sequences (28).…”

Humans are unique among all species in their ability to develop and enforce social norms, but there is wide variation in the strength of social norms across human societies. Despite this fundamental aspect of human nature, there has been surprisingly little research on how social norm violations are detected at the neurobiological level. Building on the emerging field of cultural neuroscience, we combine noninvasive electroencephalography (EEG) with a new social norm violation paradigm to examine the neural mechanisms underlying the detection of norm violations and how they vary across cultures. EEG recordings from Chinese and US participants (n = 50) showed consistent negative deflection of event-related potential around 400 ms (N400) over the central and parietal regions that served as a culture-general neural marker of detecting norm violations. The N400 at the frontal and temporal regions, however, was only observed among Chinese but not US participants, illustrating culture-specific neural substrates of the detection of norm violations. Further, the frontal N400 predicted a variety of behavioral and attitudinal measurements related to the strength of social norms that have been found at the national and state levels, including higher culture superiority and self-control but lower creativity. There were no cultural differences in the N400 induced by semantic violation, suggesting a unique cultural influence on social norm violation detection. In all, these findings provided the first evidence, to our knowledge, for the neurobiological foundations of social norm violation detection and its variation across cultures.culture | social norms | N400 | electroencephalography | EEG

“…It is possible that the left IFG, as one of the possible generators of the mid-frontal old/new effect (see Bridger, Bader, Kriukova, Unger, & Mecklinger, 2012, for a discussion), is involved in assessing the increment in familiarity relative to a pre-experimental baseline as it was suggested for the mid-frontal old/new effect (Bridger et al, 2014;Stenberg et al, 2009). Consistent with this notion, studies relating this region to familiarity used pre-existing single items (Aly et al, 2011;Angel et al, 2013;Yonelinas et al, 2005).…”

“…The mid-frontal effect was more pronounced for recognized old items and falsely recognized lures than for correctly rejected lures. Assuming that the mid-frontal old/new effect reflects familiarity as opposed to recollection (for discussion see Bridger et al (2012) and Voss and Federmeier (2011)), this suggests that some lures were recognized on this basis. Poorer performers also showed larger mid-frontal effects for old hits than better performers.…”

There is keen interest in what enables rememberers to differentiate true from false memories and which strategies are likely to be the most effective. This study measured electrical brain activity while healthy young adults performed a mnemonic discrimination task, deciding whether color pictures had been studied, were similar to studied pictures (lures), or were new. Between 500 and 800 ms post-stimulus, event-related potentials (ERPs) for correctly recognized studied pictures and falsely recognized lures compared to those for correctly rejected novel items had a left centroparietal scalp distribution. This was typical of the parietal old/new effect associated with recollection, and in line with previous evidence that similar lures may elicit false or phantom recollection as opposed to just familiarity. There was no evidence of a parietal effect for correctly rejected lures as would be expected if recall-to-reject was used. The ERP old/new effects for lures also varied with individual differences in performance. Parietal effects for falsely recognized lures were larger in better performers, who successfully rejected a greater number of lures as "similar". The better performers also showed more pronounced right frontocentral old/new effects between 800 and 1100 ms for correctly rejected and falsely recognized similar lures. The enhancement of false recollection in better performers implies false recognition of lures occurred only when more specific information was recovered about the study episodic. Together, the findings suggest reliance on recollection to decide that items were studied, supported by post-retrieval processing.
