Three stages of memory The three stages of memory consist of sensory memory, short term memory, and long term memory. Each stage has specific functions in how its stores memory, for how long, and when that memory is called upon. Sensory memory lasts about 1 - 2 seconds and is the immediate perception of stimuli in the environment. You can either dismiss that perception, or transfer it to short-term memory or perhaps long-term memory. Sensory memory is often divided into iconic (visual input) and echoic (sound) memory. It refers specifically to memory of sensory input for the first second or two. Anything longer is either short-term or long-term memory. An example of this would be if I feel a nut on a bolt and I know it needs an 8mm wrench. Short term memory, also known as active memory, is the information we are currently aware of or thinking about. Freudian psychology, calls this the conscious mind. Some sensory memory is turned into short term memory if enough attention is given to the thought. Short term memory usually last about 20 – 30 seconds. An example would be: I look up a part number and remember it long enough to order one. Many of your short term memories are forgotten, but if enough attention is given some of these memories can be taken to the next stage. Long term memory is the continuous storage of information. Freudian psychology, calls this the preconscious and unconscious. Most of the time you are not aware of what memories are being stored, but can be called upon at a later time. An example would be: I check the tire pressure and remember that it should always be 40 psi.
