<P> Echoic memory represents SM for the auditory sense of hearing . Auditory information travels as sound waves which are sensed by hair cells in the ears . Information is sent to and processed in the temporal lobe . The echoic sensory store holds information for 2 -- 3 seconds to allow for proper processing . The first studies of echoic memory came shortly after Sperling investigated iconic memory using an adapted partial report paradigm . Today , characteristics of echoic memory have been found mainly using a mismatch negativity ( MMN ) paradigm which utilizes EEG and MEG recordings . MMN has been used to identify some of the key roles of echoic memory such as change detection and language acquisition . Change detection , or the ability to detect an unusual or possibly dangerous change in the environment independent of attention , is key to the survival of an organism . One study focusing on echoic sensory changes suggested that when a sound is presented to a subject , it is enough to shape an echoic memory trace that can be compared to a physically different sound . Change - related cortical responses were detected in the superior temporal gyrus using EEG . With regards to language , a characteristic of children who begin speaking late in development is reduced duration of echoic memory . In short , `` Echoic memory is a fast - decaying store of auditory information . '' In the case of damage to or lesions developing on the frontal lobe , parietal lobe , or hippocampus , echoic memory will likely be shortened and / or have a slower reaction time . </P>
