Introduction

Sperling’s study of sensory memory was conducted in order to understand how much information the human brain can process at one time. The partial report method was used to test this. The key to the partial report method is that participants are only shown a brief glimpse of the information and are then asked to recall as much as they can.

What is the partial report method?


In the partial report method, subjects are shown a list of items and then, after a brief delay, are asked to report only on a specific subset of those items. This allows researchers to investigate how information is encoded and stored in sensory memory.

The key finding of Sperling’s study was that subjects were able to correctly report the majority of items in the subset, but they were less accurate in their reports when the list contained more items. This suggests that information in sensory memory is rapidly encoded and then quickly forgotten.

What is the significance of the partial report method?

The partial report method was significant to Sperling’s study of sensory memory because it allowed him to investigate how information is stored in the iconic memory. He found that people can only remember a limited amount of information at any one time, and that this information disappears very quickly unless it is rehearsed.

The Partial Report Method of Sperling’s Study of Sensory Memory

Sperling’s study of sensory memory was conducted in 1960. He found that the partial report method was the key to understanding how sensory memory works. This method involves showing subjects a list of items and then only allowing them to see a portion of the list. The subjects would then have to report back what they saw. This method allowed Sperling to understand how the brain processes information that is seen and how it is stored in sensory memory.

How was the partial report method used in Sperling’s study?


Sperling (1960) carried out an experiment to investigate iconic memory, or the visual sensory store. In his experiment, Sperling exposed participants to a grid of 12 letters for a very brief duration (50 milliseconds). He then asked them to report as many letters as possible. The results showed that participants were only able to report around four of the 12 letters on average.

Sperling realized that the reason for this was because participants were only able to encode a limited amount of information into their iconic memory. To overcome this, he devised the partial report method. In this method, participants were still shown the grid of 12 letters, but this time they were presented with a tone after the exposure. The tone indicated which row of letters they should report. This allowed participants to direct their attention to one particular row, and as a result, they were able to recall more letters.

The partial report method was key in demonstrating that iconic memory is indeed transient and limited in capacity. It also showed that information can be selectively encoded into iconic memory by directing attention to it.

What were the results of the partial report method?

The results of the partial report method showed that people were only able to remember 3-4 items at a time. The capacity of sensory memory is very limited and it only lasts for a brief period of time.

The Significance of the Partial Report Method

Sperling’s study of sensory memory utilized the partial report method in order to prove that sensory memory does in fact exist. Previous to this study, it was thought that people could only remember a handful of items at a time. However, Sperling’s study showed that people can actually remember a lot more than previously thought. The partial report method was key to proving this.

What does the partial report method tell us about sensory memory?

The key to the partial report method of Sperling’s study of sensory memory was to investigate the role of attention in storing and recalling information from sensory memory. Sperling found that if participants were asked to report only a specific type of information (e.g., the color of the words), they could recall more information than if they were asked to report all the information (e.g., both the color and the letter). This finding led to the conclusion that attention plays a critical role in determining what information is stored in sensory memory and, ultimately, what is remembered.

What are the implications of the partial report method?


The partial report method is a way to study sensory memory. It involves briefly presenting subjects with a stimulus, and then asking them to report on only part of what they saw.

The key to the partial report method is that it allows researchers to study how information is processed in sensory memory. This is because the subject has to remember the information long enough to report on it, but not so long that they can store it in long-term memory.

The partial report method has implications for our understanding of sensory processing. It shows that information in sensory memory is subject to decay, and that we cannot hold large amounts of information in our sensory systems at one time. Additionally, the partial report method suggests that we process information in our sensory memory in an serial, rather than parallel, fashion.

Conclusion

The key to the partial report method of sperlings study of sensory memory was to use a tachistoscope, or rapid visual scanner. This instrument allowed him to control the duration of the exposure to the list of items, and also the time at which each item was exposed. By using this method, sperling was able to determine that people can only hold about three or four items in their sensory memory at any one time.
