It enables us to combine a series of touch sensations and to play a role in identifying objects we can’t see. These memories tend to last for about two seconds. Haptic memory involves tactile sensory memories procured via the sense of touch through the sensory receptors which can detect manifold sensations such as pain, pressure, pleasure or itching (Dubrowski, 2009). Moreover, a study of language acquisition indicates that children who start speaking late are likely to have an abridged echoic memory (Grossheinrich, Kademann, Bruder, Bartling & Suchodoletz, 2010).įurthermore, lesions on or damage to the parietal lobe, the hippocampus or the frontal lobe too, would likely shorten echoic memory or/and slow down its reaction time (Alain, Woods & Knight, 1998). Additionally, a study on echoic sensory alterations suggests that a presentation of a sound to a participant is sufficient to shape a trace of echoic memory which can be compared with a different sound (Inui, Urakawa, Yamashiro, Otsuru, Takeshima, Nishihara & Kakigi, 2010). The recent use of the Mismatch Negativity (MMN) paradigm which employs MEG and EEG recordings, has unveiled many characteristics of echoic memory (Sabri, Kareken, Dzemidzic, Lowe & Melara, 2003).Ĭonsequently, language acquisition and change detection have been identified as some crucial functions of echoic memory. Hearing the whistle of a police officer.
The processing of echoic memories generally takes 2 to 3 seconds (Darwin, Turvey & Crowder, 1972).Ĭlap your hands together once and see how the sound remains for a brief time and then fades away. These are sensed by the ears’ hair cells and processed afterwards in the temporal lobe. The information which we hear enters our organism as sound waves. Sensory memory can be divided into subsystems called the sensory registers: such as iconic, echoic, haptic, olfactory, and gustatory.Įchoic memory is the sensory memory for incoming auditory information (sounds). Since it is impossible to permanently register each and every impression we have captured via these senses, as we momentarily focus on a pertinent detail in our environment, our sensory memory registers a brief snapshot of our environment, lasting for several hundred milliseconds.Īttention is the first step in remembering something, if a person’s attention is focused on one of the sensory stores then the data is transferred Throughout our lives, we absorb a tremendous amount of information via our visual, auditory, tactile, gustatory, and olfactory senses (Coltheart, 1980). Sensory memory allows for the retention of sensory impressions following the cessation of the original stimulus (Coltheart, 1980). Sensory memory is a brief storage of information in humans wherein information is momentarily registered until it is recognized, and perhaps transferred to short-term memory (Tripathy & Öǧmen, 2018).
Sensory memory is a very short-term memory store for information being processing by the sense organs.
