Dear fellows,

I'm currently planning a study about the impact of social interaction (rejection and inclusion) on the cognitive processing of emotional stimuli (negative, positive and neutral). I hypothesize that on a rejection condition, participants would have an impaired performance on a cognitive inhibition task if the stimuli presented is negative. Thus, I expect an interaction between the social interaction and the emotional valence of the stimuli on the inhibition task. 

I'm, also, exploring the possibility to test my hypothesis with the EEG. More precisely, I'm interested on the P3 component. I was wondering if it was reasonable to expect a larger amplitude of the P3 exclusively on the rejection condition when negative words have to be processed? In other words, is the P3 affected by this kind of interaction?

Thank you so much and please accept my best regards,
