Abstract
Picture naming studies have shown that alternative picture names become phonologically coactivated even when they are eventually not produced (e.g., dog when poodle is produced and vice versa). The authors investigated whether this pattern is shaped by recent experience. Specifically, they tested whether the phonological coactivation of an alternative name is attenuated, when speakers consistently only use one particular name in a large number of naming episodes. In 3 picture-word interference experiments, the authors measured the phonological coactivation of basic-level alternative names during subordinate-level naming (Experiments 1 and 3) and of subordinate-level alternative names during basic-level naming (Experiment 2). They measured the coactivation of the alternative name at different points in time with distractor words that were phonologically related or unrelated to that name. If the pattern of lexical activation is shaped by previous naming episodes and the phonological coactivation of the nonproduced alternative name decreases, interference from related distractors should be reduced in the course of the experiment. Contrary to this prediction, the interference effect from distractors phonologically related to the alternative name remained stable. This was also true when participants were not familiarized with the pictures, more naming episodes were implemented, and a consolidation phase was introduced (Experiment 3). Overall, these results indicate some limitation of incremental learning in word production.
