Sensory Memory| Sensory memory is deeply connected with the term called Perception. It is referred to as a record of the person. Sensory memory Psychology is the shortest element of memory. It is the unique ability of the memory to retrieve impression from the sensory information. It brief about the initial look of the sensory data. This sort of sensory information is required to retrieve back the information after a quick glance of a second.
Look at the situation you are walking in the street and what you see a rash driver passed in front of you in just a second. The Bike was very high in speed. You could capture just a couple of pictures or images of the bike and the biker who is sitting on it. This is a phenomenon which help us to understand the sensory memory. When you see an image of the slide feeding away very fast. This perception or particular feeling where you look at images feeding very fast is what is called Sensory memory.
Sensory memory acts as a buffer for stimulus through five senses of human body hearing, sight, touch, taste and smell. It is the memory which holds a very brief period holds the lot of information. But, the information gathered by Sensory memory is in unprocessed format, hence cannot be processed. Attention and perception decide the further process of information to the brain.
Sensory memory acts like ultra short memory who decays very early. You can hold images in your mind upto 1/5th-1/2th of a second after the perception of an item.
We have five senses in our body. Although five sensory memory is there for perception to occur.
1. Iconic Memory
Iconic memory is a sensory memory for the image. It is the visual sensory memory. It is pointed out by the Neisser in 1967 which is a very brief visual memory. Iconic memory holds the memory for visual information upto one second. Sensory memories have very very less time availability. Information in sensory memory is available for a very brief period. But Iconic memory is able to hold a huge set of information for the perception.
The available information quite high but the availability of time is quite less. So, you can not be able to perceive for a longer duration.
2. Echoic memory
Echoic Memory is for the auditory material. Echoic memory is also discovered by the psychologist Neisser in the year 1965.
Darwin, Turvey and Crowder in the year 1972 replicate the difference between Echoic memory and the Iconic memory.
- Echoic Memory has a larger capacity than iconic memory.
- Echo can last upto 20 seconds while Icon is able to hold information for upto 1 second only.
3. Haptic Memory
Haptic memory represents for the touch. There are sensory receptors all around the body to detect various sensations like pain, pressure and itching. Information travels through the neurons to the brain.
