People might be curious about the inner workings of echoic memory. When we encounter auditory stimuli, we engage directly with the sound and send the sound signals to our brain. Our brain then works to repeat and interpret the specified sound for a short time span. There are times when you feel as though you have not heard a single word that the person in front of you has said, but when you actually ask them to repeat themselves you realize that you did indeed hear what they were talking about because your brain involuntarily already stored that information for you via the echoic memory.
Over time, echoic memory can slowly deteriorate as the brain may have trouble maintaining the echoic memory if there are problems such as language development deficits or speech impairment. Sudden medical ailments can also lead to an impaired echoic memory, such as strokes. However, research indicates that echoic memory can be improved even in stroke victims by encouraging them to listen to various types of audiobooks or music on a daily basis. Echoic memory makes sense of the world of sound that we are surrounded by. Make sure you take care of it as best as you can.
