AB The contribution of two different training contexts to online, gradual lexical acquisitionwas investigated by event-related potentials (ERPs) elicited by new, word-like stimuli.Pseudowords were repeatedly preceded by a picture representing a well-knownobject (semantic-associative training context) or by a hash mark (non-associativetraining context). The two training styles revealed differential effects of repetition inboth behavioral and ERPs data. Repetition of pseudowords not associated with anystimulus gradually enhanced the late positive component (LPC) as well as speededlexical categorization of these stimuli, suggesting the formation of episodic memorytraces. However, repetition under the semantic-associative context caused higherreduction in N400 component and categorization latencies. This result suggests thefacilitation in the lexico-semantic processing of pseudowords as a consequence of theirprogressive associations to picture-concepts, going beyond the visual memory tracethat is generated under the non-associative context.
