Constraints on the range of context-independent priming from ambiguous words

The semantic priming technique was used to explore the semantic information activated by the contextually irrelevant meanings of ambiguous words in sentence contexts. The nature of the relationship between prime and target was systematically manipulated. Evidence of priming was obtained when the target was an approximate synonym of the prime (e.g., coach-bus), and when the target was a category coordinate of low similarity, but high category typicality (e.g., raincoat jumper, in Italian). No priming was obtained when the target was event related to the prime (coach-driver), nor when it was a highly similar category co-ordinate (raincoat overcoat, in Italian). However, in these latter cases, robust priming effects were obtained when the prime was presented out of context. The results are discussed in terms of the different kinds of semantic-retrieval operations that may be performed, depending upon whether or not the subjects attend to the meaning of the prime.
