Iconic Memory Module Map | |||||
|
Purpose To demonstrate some aspects of sensory register. Summary The module describes Sperling's classic experiments and allows students to demonstrate some of his findings. Nine random letters are displayed in a 3 x 3 matrix using simulated tachistoscopic projection, and students attempt to recall the letters under three different conditions: free recall; cued recall, with the cue appearing at the same time as the letters; and delayed cued recall, with the cue appearing 500 msec after the letters disappear. After each condition, the student's performance is graphed and interpreted. In most cases, students will be able to demonstrate the existence of a visual "icon" or sensory register by showing that more information is available to them than they can reproduce in a free recall task, but that this information decays sharply during a 500 msec delay.
