Abstract

The speed of naming the color of a colored square was examined with acoustic distraction to study the effects of the formation of a mental representation (neural model) of distractors. In Experiment 1, practice with the distractors (color words, noncolor words, and tones) was examined, and in Experiments 2 and 3 each color-naming trial was preceded by preexposures to sounds that could be dissimilar, similar, or identical to the upcoming auditory distractor. Consistency in the identity of ignored sounds, whether during color-naming practice or between preexposures and test, reduced interference with color naming. Consistency in voice played no role, and attended preexposures were ineffective in reducing interference. Given these results, the authors propose that mental representations of distractors include information about their task relevance, which modulates disruption of the primary task.
