title: Semantic priming by irrelevant speech.
abstract: To-be-ignored, task-irrelevant speech disrupts serial recall performance relative to a quiet control condition. In most studies, the content of the auditory distractors had no effect on their disruptive potential, one's own name being one of the few exceptions. There are two possible explanations of this pattern: (1) Semantic features of the irrelevant speech are usually not processed, except for highly relevant auditory distractors, or (2) semantic processing of the irrelevant speech always occurs, but usually does not affect serial recall performance. To test these explanations, we presented to-be-ignored auditory distractor words drawn from different categories while participants memorized visual targets for serial recall. Afterwards, participants were invited to what they believed to be an unrelated norming study, in which they were required to spontaneously produce words from the categories from which the auditory distractor words were drawn. Previously ignored words were produced with a higher probability than words from a parallel, nonpresented set, demonstrating that features of to-be-ignored, task-irrelevant speech that do not interfere with immediate serial recall performance are nevertheless processed semantically and may have substantial effects on subsequent behavior.
