The semantic interference effect in the picture-word interference paradigm: does the response set matter?

In three picture-word interference experiments we explore some properties of the semantic interference (SI) effect in the picture-word interference paradigm. In Experiments 1 and 2, we test whether SI may be obtained when the distracter words are not part of the response set and when only one picture per semantic category is included in the experiment. In Experiment 3, we explore if the magnitude of the SI effect depends on whether or not the distracter words are part of the response set. Reliable SI effects were obtained in all three experiments and the magnitude of the effect did not vary as a function of whether or not distracter words are part of the response set. These results are problematic for the selection mechanism in the WEAVER++ lexical access model (Levelt, W. J. M., Roelofs, A., & Meyer, A. S. (1999). A theory of lexical access in speech production.
