Duration of the aftereffects of verbal stimulation to one ear was measured under conditions where Ss concurrently shadowed another message to the other ear. Immediate recall did not approach 100% in any situation. Recall of a single letter was substantial over an interval of 6 sec. Recall of 2 letters was poor. Recall of a cued word was not appreciable unless no other words intervened. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
