Semantic interference across word classes during lexical selection in Dutch

Abstract

Using a novel version of the picture-word interference paradigm, Momma, Buffinton, Slevc, and Phillips (2020, Cognition) showed that word class constrained which words competed with each other for lexical selection. Specifically, in speakers of American English, action verbs (as in she’s singing) competed with semantically related action verbs (as in she’s whistling), but not with semantically related action nouns (as in her whistling). Similarly, action nouns only competed with semantically related action nouns, but not with action verbs. As this pattern has important implications for models of lexical access and sentence generation, we conducted a conceptual replication in Dutch. We found a semantic interference effect, however, contrary to the original study, no evidence for a word class constraint. Together, the results of the two studies argue for graded rather than categorical word class constraints on lexical selection.
