What is the Sperling experiment?
Sperling’s Experiments on Iconic Memory In 1960, George Sperling performed experiments designed to demonstrate the existence of visual sensory memory. The results of these experiments suggested that the human visual system is capable of retaining information even if the exposure is very brief.
What was the importance of the partial-report condition in Sperling’s 1960 experiment on iconic memory?
However, in Sperling’s partial-report experiment, participants could recall the portion of numbers they were asked to report back relatively accurately, compared to the whole-report approach. This gave Sperling the indication that we can perceive more than just a few images.
What was the purpose of Sperling’s 1960 study why did he need to use a partial-report format to study iconic memory What does it tell us about iconic memory?
In 1960, George Sperling began his classic partial-report experiments to confirm the existence of visual sensory memory and some of its characteristics including capacity and duration.

What is iconic memory Sperling?
Iconic memory is a component of sensory memory that involves a fast-decaying visual information store (Sperling, 1960). It provides a coherent yet fleeting representation of our visual perception (Pratte, 2018).
What was the importance of the partial report method used by Sperling quizlet?
Explain Sperling’s delayed partial report method. Used to determine the time course of fading. The letters were flashed on and off then the cue tone was presented after a short delay. When the cue tones were delayed for one second after the flash, subjects were able to report only slightly more than 1 letter in a row.
What is Sperling partial report?
Instead of a string, an array of letters (3 x 3 or 4 x 4 are common) and after the letters are presented, a signal is given to indicate which row the person is to recall. So the participant is asked to recall only some of the items but they cannot know which items before hand. Thus, Sperling called this partial report.
What did Atkinson and Shiffrin find?
The multi-store model of memory (also known as the modal model) was proposed by Richard Atkinson and Richard Shiffrin (1968) and is a structural model. They proposed that memory consisted of three stores: a sensory register, short-term memory (STM) and long-term memory (LTM).
Sperling’s Experiments. In 1960, the cognitive psychologist George Sperling conducted an experiment using a tachistoscope to briefly present participants with sets of 12 letters arranged in a matrix which had three rows of letters (Schacter, Gilbert & Wegner, 2011).
What did George Sperling discover in the 1960s?
In 1960 George Sperling demonstrated that, for a brief period following the termination of a 50-millisecond display of letters, more information was actually available than an observer could normally report.
What is Sperling’s theory of memory?
Sperling hypothesized that the participants had forgotten this information while attempting to recall it. In other words, Sperling held that all of the nine letters were in fact stored in the participants’ memory for a very short time, but that this memory had faded away. Hence, the participants could recall only 4 or 5 of the 9 letters.
