Echoic memory
The echoic memory ( echoic sensory memory ) is understood to mean the maintenance of auditory perception for four to 18 seconds. The hypothetical term goes back to Ulric Neisser , who referred to previous studies by George Sperling , and was later taken up again mainly by Nelson Cowan .
It can therefore be assumed that one has a sensory memory for every sensory unit , i.e. H. Stimulus perceptions are subconsciously maintained for a short time after they have ended. Research has so far focused on the visual (iconic) and auditory (echoic) areas. The echoic memory is comparable to the iconic memory . It stores more than can normally be reported and semantically understood. One assumes 5 (4.4–6.2) chunks . However, this briefly stored information is quickly displaced by new stimuli.
The echoic memory becomes clear, for example, when one is absorbed in reading and something is asked. Often people are asked “What did you say?” Before the sentence is finished, however, you remember the question and can answer it without having to ask it again.
