The main aim of presented study was to investigate the influence of distraction on working memory functioning (mainly articulatory loop). It was expected that the results of the experiment would allow us to resolve between two competing models of articulatory loop ('storage' model and 'tape' model). Working memory search task based on Sternberg paradigm was used. Subjects were asked to memorize sets of three-letter words or trigrams that did not have any meaning. In the experimental conditions distractor (either a song or a melody) was introduced. Distraction was effective only in the most difficult conditions of the memory task. There were no differences between two kinds of distraction. Results suggest that both 'storage' and 'tape' models of articulatory loop could be hold, depending on type of material to be memorized.
