The N400 has been seen to be larger for concrete thanabstract words, and for pseudowords than real words. Using a word vectoranalysis to calculate semantic associates (SA), as well as ratings foremotional arousal (EA), and a measure of orthographic neighbourhood (ON), thepresent study investigated the relation between these factors and N400 amplitudes during a lexical decision task usingSwedish word stimuli. Four noun categories differing in concreteness: specific(squirrel), general (animal) emotional (happiness) and abstract (tendency) werecompared with pseudowords (danalod). Results showed that N400 amplitudes increased in the order emotional < abstract < general < specific < pseudoword. A regression analysis showed that the amplitude ofthe N400 decreased the more semanticassociates a word had and the higher the rating for emotional arousal it had.The N400 also increased the moreorthographic neighbours a word had. Results provide support for thehierarchical organisation of concrete words assumed in lexical semantics. They also demonstrate how affectiveinformation facilitates meaning processing.
