In recent years, Janssen, Schirm, Mahon, and Caramazza (2008) observed a significant semantic interference effect in the task-switching version of the picture-word delayed naming paradigm. They argued that the semantic effect originates from the post-lexical level of speech processing. The present study conducted two experiments to test the reliability of such a finding using the picture- word delayed naming paradigm. In Experiment 1, a standard delayed naming task was used where participants engaged in the delayed naming of the picture regardless of the distractor word that appeared after the picture. In Experiment 2, a task-switching version of the same task was used where participants engaged in the delayed naming according to the color of the distractor word. The results of both Experiment 1 and 2 revealed no significant semantic interference effect, which supports the claim that the semantic effect originates from lexical competition rather than post-lexical level processing during speech production.
