    Study Notes

    Short-Term Memory and Sperling's Experiments

    • Sperling's delayed partial report experiments showed that participants were able to report only slightly more than 1 letter in a row after a 1-second delay
    • The graph in Figure 5.6 illustrates the decrease in performance due to the rapid decay of iconic memory
    • Sperling concluded that a short-lived sensory memory, iconic memory, registers all or most of the visual information but decays within less than a second
    • Echoic memory, the persistence of sound, lasts for a few seconds after the original stimulus presentation
    • Short-term memory (STM) is involved in storing small amounts of information for a brief period of time
    • Most information in STM is eventually lost, with only some reaching the more permanent store of long-term memory (LTM)
    • STM is responsible for a great deal of our mental life, as it is our window on the present
    • Early research on STM focused on determining its duration and capacity through recall experiments
    • Recall involves participants being presented with stimuli and then, after a delay, asked to report back as many of the stimuli as possible
    • One major misconception is that short-term memory lasts for a relatively long time, when in fact it is involved in storing information briefly
    • Short-term memory is not uncommonly referred to for events remembered from a few days or weeks ago, but its duration is actually brief
    • Recall is also involved in recollecting life events and facts learned, and can be analyzed to determine patterns in the way items are recalled
