Explored the effects of two variables in the picture-word interference paradigm: semantic relatedness and the level of categorization of distracts relative to pictures' names. Results suggest that the effect of semantically related distractors depends on the level of categorization at which the response has to be given. Semantically unrelated distractors at the same level of categorization as that of the response interfere more than unrelated distractors at different levels.(VWL)
