Sensory memory holds information received immediately from a person's senses into the human brain. The information is stored for just an instant and is relatively unprocessed. The duration of sensory memory depends on what type of memory is being taken in. Iconic memory, visual memory, lasts less than one second. Echoic memory, auditory memory, lasts less than four seconds. After receiving the information, the brain quickly decides if it will be processed enough to remain in short term memory or if it will be discarded.
