N2 - There is a body of research reporting an increase in N400 amplitude while processing semantically incongruent verbal stimuli.However, there is no evidence to suggest that ERPs during semantic incongruence might be associated with certain psychologicalparameters, such as IQ. We tested whether ERPs during responses to perceptions of verbal antilogies differed in participants withvarious IQ levels. We expected to find differences in the N400 and P600 components.MethodWe assessed the participants’ (N=155) IQ with Raven’s "Standard Progressive Matrices" and ranked them according to the scores theyachieved. Out of the initial pool of participants, we composed 3 groups (N=15 each): HighIQ (120–130 scores), ModerateIQ (102–116scores), LowIQ (83–100 scores). The groups were presented with 3 types of visual stimuli: verbal antilogies (to bereave generously),normal (to gift generously) and meaningless (to sink generously) phrases while ERPs were recorded.ResultsDifferences in ERPs during responses for the 3 types of stimuli were found between the groups. HighIQ: N400 was more pronouncedin response to antilogies and meaningless phrases vs. normal phrases; P600 was more pronounced in response to antilogies andnormal phrases vs. meaningless phrases. ModerateIQ: N400 was more pronounced in response to normal phrases vs. antilogies andmeaningless phrases; differences in P600 were the same as HighIQ. LowIQ: N400 was more pronounced in response to meaninglessphrases vs. antilogies and normal phrases; no differences in P600 were found between the 3 types of stimuli.ConclusionsWe interpret these findings as support for the idea that participants with higher IQ (unlike those with low or moderate IQ) use moresufficient cognitive schemes for processing semantic incongruence, which allow them to take antilogies as similar to normal phrasesand opposite to meaningless ones.Supported by the President of the Russian Federation grant № МК-7507.2016.6.
