Sensory memory, short-term memory, and long-term memory differ from each other, when it comes to the duration, capacity, and function. Sensory memory has a large capacity for information, but it has a brief duration. The short-term memory and long-term memory have limited and unlimited capacity respectively. While the duration of sensory memory ranges up to 4 seconds, the duration of the short-term memory is about 20-30 seconds. The information can be stored in long-term memory indefinitely. An important function of sensory memory is to briefly [url=http://www.stressfreebrains.com/neurovarium/]Neurovarium[/url] store sensory impressions or the exact copies of the sensory inputs (visual, auditory, gustatory, olfactory, and haptic), as a buffer memory till it is transferred into the short-term memory. The element of attention is extremely important in case of sensory memory. Out of all the sensory inputs, only the information that we pay attention to gets transferred to the short-term memory. The rest of the information is discarded or forgotten. The sensory information that is received vanishes in a few seconds, which in turn prevents us from getting overwhelmed by multiple sensory stimuli.
