Journal Of Experimental Psychology: Human Perception And Performance


In 3 experiments, 40 undergraduates practiced counting digits, a task subject to Stroop-type interference, and then were tested in a variety of transfer conditions. Results indicate that digits lose their ability to distract as a result of practice but that this loss is highly specific; practice in ignoring 1 pair of distractors (2 and 4) did not improve later performance when ignoring a different pair (1 and 3). However, this practice effect did transfer to distractor stimuli having the same meaning as the stimuli ignored in practice ({two} and {four}, but not {to} and {for}). The results can be explained either in terms of active learning to suppress distraction or in terms of habituation of competing responses.
