In a psychological study of short-term memory, irrelevant speech effects refer to the degree to which the memorization process is impaired by irrelevant background speech. An analysis of irrelevant speech effects was carried out and published. Subjects performed the memorization task under two conditions: (1) with irrelevant background speech and (2) in silence. The difference in the error rates for the two conditions-called the relative difference in error rate (RDER)-was computed for each subject. A histogram summarizing the RDER values for the subjects is displayed below.
