National Memory Day on March 21 is a day celebrating the brain as a function of the human body that helps us to recall events and retrieve experiences from the past.


Most people think of memory as something that is used to remember past events. However, there are actually three functions of memory. The first function of memory is to acquire information. The second and third functions of memory involve the ability to retain and retrieve information.

Test Taking Tips

  1. Acquire the information by reading, listening, and organizing your notes from class.
  2. Retain the information by using repetition. Find a quiet place away from distractions. Read and re-read your information.
  3. Test yourself or have a friend test you on the information.
  4. Take your test. Your brain will retrieve the information from your memory once you begin to recognize the information on the test.

When the time comes to take the test, your brain will retrieve the information from your memory necessary to take the test.

What are the 4 different categories of memory?

  1. Sensory Memory. This type of memory helps to remember sensory information after a certain stimulation has ended. Sensory memory is obtained by sight (iconic), auditory (echoic), and touch (haptic).
  2. Short-term Memory. This type of memory helps recall information for a brief period of time. Short-term memories only last for about 30 seconds.
  3. Working Memory. This type of memory involves immediate information that is necessary for completing cognitive tasks.
  4. Long-term Memory. This type of memory is any kind of information that can still be recalled after 30 seconds. Long-term memory is further broken down into explicit, which is information we deliberately want to remember (such as a friend’s birthday) and implicit, which are memories that we pick up subconsciously.

Uncommon Facts About Memory

Memory affects every stage of life, including the time before we were born. According to recent research, short-term memory begins to form in the womb at about 30 weeks gestation. When babies are born, memory helps babies bond with their mother. For instance, babies remember what their mother’s voice sounds like which helps them recognize their parents voices once they are born. Young children also use memory to learn how to navigate the world. No matter what their stage of life, all humans rely on memory to accomplish a variety of tasks. From pre-school through college, memory is necessary for learning new skills and advancing to the next level.

Memory Loss

Memory is involved in a large part of the human experience. Sadly, though, memory is one thing that people can lose. This is especially true of aging adults. As aging adults age, the brain changes with them. These age-related changes are usually a result of lower executive function in the brain. While older people can still learn new things and retain information, it might be more difficult to do so.
