What is haptic memory?

Haptic memory was coined by Ulric Neisser in 1967. It is the aspect of human cognitive processing that deals with touch stimuli from the outside world.

Haptic memory is from of sensory memory that refers to the recollection of data acquired by touch after a stimulus has been presented.

Once the touch is perceived and enters the sensory memory haptic memory information then moves from short-memory to long term memory.

Haptic memory, also known as tactile memory, which can hold up to five tactile stimuli at a time.

It is used regularly when assessing the necessary forces for gripping and interacting with familiar objects.

Haptic object identification is made possible by combining vision and cognition. The use of visual imagery and verbalization helps improve haptic memory and discrimination.

Visual memory of iconic memory

There are three types of sensory memory:
*Iconic memory
*Echoic memory
*Haptic memory

Iconic memory is the sensory memory for visual stimuli. A very common example for iconic memory is the light beam that for example a pocket lamp leaves behind when it is moved rapidly through the dark night.

The apparently real light beam is only created by the images one retrieves and stores in the sensory memory while the pocket lamp moves.

Icons do not last long, As soon as human see the object, an icon is formed and it last for only about half a second before it decays.

The iconic image of the image registered on the retina just before a movement may persist long enough to enable human to see the events in their visual environment without interruption.

Without iconic memory, human visions would perhaps consist of s series of flashes.

Iconic memory is the initial stage in an information-processing model. Although highly transient, it has a large capacity.
