Effect of word association on linguistic event-related potentials in moderately to mildly constraining sentences

Abstract The processing of word associations in sentence context depends on several factors. EEG studies have shown that when the expectation of the upcoming word is high (high semantic constraint), the within-sentence word association plays a negligible role, whereas in the opposite case, when ther...
