Beyond the N400: Complementary access to early neural correlates of novel metaphor comprehension using combined electrophysiological and haemodynamic measurements

The temporal dynamics underlying the comprehension of scientific metaphors and poetic metaphors

“…Consistent with our predictions of the N400, although there was a graded effect of the four experimental conditions on the N400 amplitude with both novel metaphors resulting in the most negative waveform as reported by several other studies Lai et al, 2009;Rutter et al, 2012;Schneider et al, 2014), scientific metaphors and poetic metaphors did not differ significantly from each other. Taken together with the claim that the N400 component indexes higher-level integrative processes in priming studies (Brown et al, 2000;Tzuyin Lai and Curran, 2013), similar N400 amplitudes for scientific metaphors and poetic metaphors in the current study can be seen as similar efforts to establish a connection between the two semantically distant concepts conveyed through the stimuli.…”

Brain processing of visual metaphors: An electrophysiological study

“…Other experiments replicate these results (cf. (De Grauwe, Swain, Holcomb, Ditman, & Kuperberg, 2010;Lai, Curran, & Menn, 2009;Schneider et al, 2014;Tartter, Gomes, Dubrovsk, & Molholm, 2002) so this graded N400 metaphor effect seems to be further confirmed.…”

Emotions and BIS/BAS components affect brain activity (ERPs and fNIRS) in observing intra-species and inter-species interactions

“…Specifically, the use of NIRS in a topographic approach for measuring responses to emotions allows to investigate regional cortical activation changes that are related to emotional manipulations in general, and to link certain EEG effects to the regional hemodynamic changes Herrmann et al 2008). The latter strategy enabled us to investigate whether and how specific emotion-related electrophysiological effects are associated with distinct cortical activation patterns within the emotion perception network (Schneider et al 2014). Some adjunctive speculations could also be added to underline that the resemblance of ERP and O2Hb measures may confirm the strength relationship existing between electrophysiological changes and hemodynamic modulations within the prefrontal areas when emotional cues are processed.…”
