Sensory memory (SM) allows individuals to retain impressions of sensory information after the original stimulus has ceased.

SM is considered to be outside of cognitive control and is instead an automatic response. The information represented in SM is the “raw data” which provides a snapshot of a person’s overall sensory experience. The formation of a SM trace is independent of attention to the stimulus. Each SM store represents an immense amount of detail resulting in very high resolution of information.
