Because cognitive linguists assert that primary and complex conceptual metaphors are theoretical constructs with a plausible yet uncertain psychological reality, we investigated if and how EEG coherence would differ between these two categories during comprehension. We formalized an algorithm of conceptual metaphor processing for the purpose of hypothesis testing, before collecting EEG data from 50 normal adults, looking for condition-specific EEG coherence patterns. Results confirm the
