Wirkung intermittierender akustischer Reize auf mentale Prozesse

In a Sternberg experiment, the influence of rhythmic acoustic stimuli on the scanning rate of short-term memory was studied. During the experiment, 60 subjects heard rhythmic or arrhythmic impulse noises with different rates of repetition. Results showed that the scanning rate of short-term memory is lowest if the impulses are arrhythmic. With rhythmic impulses at high rate of repetition, an accelerated scanning rate was obtained. The results can be interpreted as consequences of interference processes and as adaptational effects of internal processing rhythms.
