The study of lexical ambiguity has played an important role in characterizing hemispheric lexical retrieval mechanisms (Burgess & Simpson, 1988). However, two factors that may affect lexical retrieval are potentially confounded when studying subordinate word meanings: a weaker association strength and incompatibility with the dominant meaning of the word. These two factors are empirically manipulated in single word priming study using unabmbiguous nouns as the primes and targets which represent their semantic features. At the 750 ms SOA, in the left hemisphere, there is priming for both the dominant and subordinate/compatible features and no priming for the subordinate/incompatible features.
