In the experiment replicated here, participants hear two sets of digits simultaneously, one in each ear. They tend to report all of the digits from one ear first, and then the digits from the other ear.

In this classic experiment, Broadbent asked subject to listen to two recorded strings of digits, one played to each ear, simultaneously.  Thus, subjects heard two digits (one in each ear), then another two, and then another two, and then reported what they heard.  Broadbent found that there was a strong tendency for subjects to report the three digits heard in one ear, and then the three heard in the other ear.  This was evidence in favor of his early, blocking filter model of auditory attention, which suggested that we can attend to only a single attentional “channel” (here, one ear) at a time, blocking input from the other channel.  In this interpretation, the subject reports the digits heard in one ear and then switches attention to the auditory memory of the information in the other ear in order to report it.
