Do Part–Whole Relations Produce Facilitation in the Picture–Word Interference Task?

Abstract

Three experiments used the picture–word interference task to evaluate competing models of lexical access in spoken word production. Both the presence of a part–whole relation and association between the target and the interfering word were manipulated. Part terms associated with targets produced facilitation at early stimulus onset asynchronies (SOAs; –300 ms in Experiment 1, –300 and –150 ms in Experiment 3), but not at SOA 0 ms. Otherwise, part terms tended to produce interference, with unassociated part terms producing a significant semantic interference effect (SIE) at SOA of 0 ms in Experiment 1, and a similar trend in Experiment 3. Experiment 2 replicated the materials and procedure of Costa, Alario, and Caramazza (2005, Experiment 2. On the categorical nature of the semantic interference effect in the picture–word interference paradigm. Psychonomic Bulletin & Review, 12(1), 125–131), yet failed to find any semantic facilitation at SOA 0 ms. We propose that these findings are consistent with lexical competition accounts of SIE but difficult to explain in terms of the plausibility of the interfering words as responses to the target.
