1. Sensory Memory
Sensory Memory is a kind of memory involves storage of brief events, such as sights, sounds, and taste.
Sensory memory is a relatively automatic form of memory.
Stimuli from the environment are processed first in Sensory Memory: storage of brief sensory events, such as sights, sounds, and tastes. It is very brief storage—up to a couple of seconds.
Sensory information about sights, sounds, smells, and even textures, which we do not view as valuable information, we discard. If we view something as valuable, the information will move into our short-term memory system.
