[2] A common demonstration of SM is a child's ability to write letters and make circles by twirling a sparkler at night.
For example, children have been shown to remember specific "sweet" tastes during incidental learning trials but the nature of this gustatory store is still unclear.
[3] However, sensory memories might be related to a region of the thalamus, which serves as a source of signals encoding past experiences in the neocortex.
The information represented in SM is the "raw data" which provides a snapshot of a person's overall sensory experience.
He calculated that the glowing coal needed to make a complete circle in under 100ms to achieve this effect, which he determined was the duration of this visual memory store.
[13] Today, characteristics of echoic memory have been found mainly using a mismatch negativity (MMN) paradigm which utilizes EEG and MEG recordings.
[15] With regards to language, a characteristic of children who begin speaking late in development is reduced duration of echoic memory.
Information from receptors travel through afferent neurons in the spinal cord to the postcentral gyrus of the parietal lobe in the brain.
Evidence for haptic memory has only recently been identified resulting in a small body of research regarding its role, capacity, and duration.
[20] Patients undergoing regional anesthesia can have incorrect, "phantom" perception of their limb positions during a procedure.
A longstanding neurological explanation of this effect was that, without incoming signals from proprioceptive neurons, the limb perception system presented to consciousness a default, slightly flexed position, considered to be a universal, inborn "body schema".
[21] However, more deliberate experimentation, varying patient limb position prior to anesthesia, has established that there is a proprioceptive memory store, which informs these perceptions.
[25] The hypothesis states that we remember limb positions which are used in common tasks, such driving, riding a bike, eating with a fork, etc.
