Physiological Evidence That a Masked Unrelated Intervening Item Disrupts Semantic Priming: Implications for Theories of Semantic Representation and Retrieval Models of Semantic Priming

Event-related potentials were recorded in a paradigm where an unrelated word was interposed between two related words. In one condition, the intervening item was masked and in another condition it was not. The N400 component indicated that priming of the related word was disrupted by the intervening item whether it was masked or not. The data are interpreted to be inconsistent with retrieval models of priming.
