Memory is an organism's ability to store, retain, and recall information and experience. Individual attention is necessary to store memory in the first place. Failure to retain the information can result failure to retrieve the information later. The content of the information can also determine the individual's ability to recall the information. As we know the information which is exciting is more remembered than the information which is ordinary. Psychologists divide memory in to three categories based on their capacity and the length of time each memory is expected to last, even if the distinction among these three memories are not always clear. These three memories are: sensory memory is the shortest memory which stays only a few second but it contains detailed information. The perceptual information in sensory memory appears in different forms like as iconic, echoic, and other forms of memory. Short term memory stay for 10-15 seconds little bit longer than sensory memory and has limited capacity like seven plus or minus two, however it is possible to remember more digit by using the system " chunk" that means by organizing information in to meaningful groupings. It is also possible to extend the duration of information in short term memory by "rehearsal" that is repeating the information over and over again like a phone numbers until we dialed. It is also called working memory because it contains the information that lets us remember that we are on the process of working. Its process takes place in hippocampus. Long term memory is memory that last for years or even longer. It contains a lot of information about something we know since from our child hood age. The long term memory is so fascinating because it reminds me about neurons long -term potentiation that we learned in unit three. According to Hbb's rule "cells that fire together, wire together", this means the activity of one neuron will tend to produce the activity of the other neuron. This is the reason why Taxi drivers developed the large hippocampus. The process of long term memory starts in hippocampus and stored permanently in the brain cortex. The reason I chose this topic is memory is very essential to our daily life in order to survive.
