Echoic Memory and Its Relation to Other Types of Memory

Close

Echoic memory, also known as auditory sensory memory, involves the short-term recall of sounds you’ve just heard. The memory of a sound might linger in your mind very briefly after the actual auditory stimulus has ended. It is a bit like an echo of a sound that exists only in your mind.

The brain utilizes severaldifferent types of memory, and echoic memory serves an essential purpose. While it is very short, lasting around four seconds, it allows us to temporarily store the sound until it can be processed.

tl;drWe’ve all heard a sound before that seems to stick out in our minds. Maybe it’s a ringing noise or a honking noise. Perhaps it’s the sound of your cat’s meow or dog’s bark. Whatever the noise, it seems to linger in your brain long after the sound has stopped. This is what’s known as echoic memory.Unlike images that you can repeatedly go back and look at, you cannot do that with sound (unless it’s recorded of course). This is where echoic memory comes in because it allows us to recall sounds even when we’re no longer in earshot of them.There are a few factors that can influence your auditory sensory memory and it may be possible to even improve our echoic memory.

Echoic memory is defined as a type of sensory memory that temporarily stores auditory information. This serves an essential purpose: it allows a sound to be stored just long enough to be processed and understood.

During the 1970s, researchers discovered that auditory information will disappear from memory after about five seconds—unless you pay attention to it.By focusing yourattentional spotlighton the sounds, the information will more likely make its way intoshort-term memory.

What makes echoic memory so important? Unlike visual information, which the viewer can look at often for as long as they want and be reviewed when needed, sounds are fleeting. They are presented once and usually cannot be re-experienced unless an audio recording exists.

By having echoic memory, people are able to briefly hold on to that sound so that it can then be processed and transformed into meaning.

According to one model, sensory memory is the firststage of memory. At any given moment, you are taking in sensory information about the world around you. Because there is no way to focus on all of the different details of every sensation you experience, yourbraincreates a snapshot of your sensory experience. This allows you to then focus on details that you might have missed.

Echoic memory is automatic, meaning it happens without having to make a conscious effort.

Once the sound reaches the brain, an echoic memory is formed. The brain processes this information and then stores it in the primary auditory cortex (PAC) on the opposite side of the brain that receives the sound.

The brief storage in echoic memory gives the brain time to interpret the sound and determine its characteristics. The sound may be transferred into working memory for further interpretation.

Information also cannot be retained in echoic memory through rehearsal. Subsequent sounds are also continually displacing the previously heard information. This ever-updating nature enables echoic memory and other types of sensory memory to act as real-time monitors for new information in the environment.

Echoic memory is an important part of your experience of the world, allowing you to store auditory information long enough that you can process and understand it.

Echoic memories are very brief, lasting in the auditory storage system for approximately two to four seconds.

Brain imaging technology has also allowed researchers to learn more about how auditory sensory memory works. In one study, researchers found that after a sound stimulus, activity occurs in a portion of the auditory cortex and lasts around two to five seconds after the sound.

Echoic Memory vs. Iconic Memory

However, echoic memory lasts longer thaniconic memory, which is the ultra-short memory of visual imagery. Where a sound might linger in your echoic memory for up to four seconds, your ability to store visual information lasts for just a few hundred milliseconds.

While iconic memory is incredibly short, visual imagery is more enduring. In most cases, you can spend time looking at visual stimuli for longer periods, or you may even be able to view it repeatedly.

A sound, on the other hand, is often only produced once. Depending on the source of the sound, you may never be able to experience it again. This is why echoic memory is so important.

Echoic memory allows you to briefly hold on to this aural information to fully understand it, even after the original source is gone.

Examples of Echoic Memory

Some examples of how echoic memory is used include:

There are certain factors or conditions that can impact echoic memory and cause impairment in the ability to temporarily store auditory memories. Factors that can affect this type of memory include:

Evidence indicates that echoic memory improves between the ages of two and six and plays an important role in cognitive development.Auditory sensory memory continues to improve into adulthood but eventually decreases as people enter old age.

When people experience impairments in echoic memory, they experience problems with auditory processing and communication. This can cause poor understanding, difficulty with speech,and problems in learning. Kids who have problems with echoic memory also havedevelopmental language disorders.

If you think you or your child might have an echoic memory impairment, talk to your doctor. They can perform tests to look for problems and recommend treatments to help with your specific diagnosis.

The answer is: maybe. While the typical duration of echoic memory is less than four seconds, some people appear to have better auditory sensory memory than others. In one older study, for example, one participant demonstrated echoic memory duration lasting as long as 9.7 seconds.

Such abilities are not typical, but they suggest that this capacity varies from person to person and that it may be possible to improve your memory for sounds.

Another way to maximize your ability to remember sounds is to pair spoken words with visual information. Presenting the information so it is represented in both echoic and iconic memory can increase the likelihood of being remembered.

Memoriesare generally classified into different types of stages. Generally speaking, the four different kinds of memory are sensory memory, short-term memory, working memory, and long-term memory.

Sensory Memory

Echoic memory is a type ofsensory memory. In addition to echoic and iconic memory, there is also the memory for touch which is known as haptic memory.

Short-Term Memory

When a sensory memory occurs frequently, when you attend to it, or you attach it to other memories, it can then move from sensory memory into short-term memory. This type of memory is longer-lasting than sensory memory but still relatively short.

Research suggests that information can be retained in short-term memory for about 30 seconds.

Working Memory

Working memory is sometimes described as another type of memory, but others suggest it is a type of short-term memory. It involves the small amount of information and memories that a person uses at any given moment to perform cognitive tasks.

For example, auditory information transferred from echoic memory into short-term memory might become active in working memory, such as a musician performing a note after they hear it.

Long-Term Memory

If the information in short-term memory is repeated or rehearsed enough, it becomes more likely to enterlong-term memory. For example, a song you hear repeatedly might be stored in your long-term memory so that you can perfectly recall the exact sound.

Long-term memories are usually divided into two categories:explicit and implicit long-term memory. Explicit long-term memories involve information that is consciously and effortfully learned and recalled. Implicit long-term memories are those that form unconsciously.

Certain health conditions can affect a person’s ability to access long-term memories. For example, echoic memories that have been transferred into long-term memory may be lost or become inaccessible if a person has a medication condition such as Alzheimer’s disease.

What This Means For YouSounds that you experience are perceived and enter echoic memory one at a time. This storage for sensory memory allows you to piece together and make sense of the information that you are hearing, even after the original auditory stimulus has ended.Echoic memory can also transfer information into short-term memory, where it can be further interpreted.Echoic memory is very brief and certain factors may impair it, including age, certain medical conditions, and hearing loss. Utilizing strategies to improve your memory and take care of your help can ensure that your memory for sounds remains strong.
