Echoic memory
Echoic memory refers to a specific type of sensory memory responsible for storing all the sound stimuli we are exposed to. It is a very brief sensory memory of some auditory stimuli. An example of usage of echoic memory in real life is when a person is listening to his friend’s story, but got distracted by his own thoughts and worries and did not concentrate on what his friend was saying. He was technically hearing the words his friend is saying, because he is capable of it physically, so the brain perceives sensory input. But since he is not concentrating on them actively to perceive the sense of the words, his brain treats them as another stimuli of the surroundings and judge it to be proceeded with echoic memory. For the question given above, Mr Silver’s experience most clearly illustrates echoic memory.
For a moment after hearing his dog's high-pitched bark, Mr. Silvers has a vivid auditory impression of the dog's yelp. His experience most clearly illustrates echoic memory.
There are two types of memory such as explicit memory and implicit memory, and then the three major memory stages such as: sensory, short-term, and long-term.
Echoic memory is the sensory memory that registered specific to auditory information or sounds. The sensory memory for sounds that people have just perceived is the form of echoic memory. Unlike visual memory, the auditory stimuli cannot be scanned over and over.
Echoic memory is ultra-short-term sensory memory, and it lasts a very brief time. It does last much longer than iconic memory. Echoic memory has been found to last between two and four seconds depending on the type of study. Sound definition is a particular auditory impression such as tone.
The differences between echoic and iconic memory is: Iconic refers to visual memory while echoic refers to auditory memory.
