The experiment by Peterson and Peterson focused on the role of rehearsal in short-term memory. Subjects were given a series of numbers to remember and then asked to count backwards by threes for a certain amount of time (which prevented rehearsal). The results showed that without rehearsal, information was lost from short-term memory within a matter of seconds. Therefore, the experiment highlights the importance of rehearsal for maintaining information in short-term memory.
