Darwin, Turvey & Crowder (1972) extended the partial report procedure to the auditory domain by playing letters simultaneously in the left ear, the right ear and both ears (preceived as originating in the middle of the subject's head). They found:

A. A partial report advantage of smaller magnitude in echoic memory than in iconic memory.
B. A partial report advantage of larger magnitude in echoic memory than in iconic memory.
C. No partial report advantage in echoic memory.

Ans: A. A partial report advantage of smaller magnitude in echoic memory than in iconic memory.
