Repeated naming affects the accessibility of nonselected words: Evidence from picture-word interference experiments

This study traced different types of distractor effects in the picture-word interference (PWI) task across repeated naming. Starting point was a PWI study by Kurtz et al. (2018). It reported that naming a picture (e.g., of a duck) was slowed down by a distractor word phonologically related to an alternative picture name from a different taxonomic level ("birch" related to "bird") when compared to an unrelated control, indicating that the alternative name was (phonologically) coactivated. Importantly, the effect was stable across repeated naming. The authors argued that this stability challenges adaptive models of word production according to which coactivated but nonselected words become less accessible for future retrieval; such a change in lexical accessibility should have been reflected in reduced interference. Using a similar experimental protocol as Kurtz et al., our study looked at the stability of different distractor effects in PWI. Interference from a distractor word phonologically related to an alternative name was stable across repeated naming, replicating Kurtz et al. In contrast, interference from a distractor word denoting a semantic category coordinate ("stork") was reduced across repeated naming. A similar pattern was found for a distractor word corresponding to an alternative name ("bird"). Facilitation from a distractor word phonologically related to the target name ("dust"), in contrast, was stable across repeated naming. We discuss the implications of these findings with respect to the issue of changes in the accessibility of lexical representations, the use of the PWI task in this context, and the use of this task in general.
