As any student can tell you, sometimes it takes a lot of work and effort to commit information to memory. When you are studying for a big exam, it might take hours of rehearsal in order to remember what you studied. However, some other events, details, and experiences enter our memory with little or no effort. For example, on the way to class you might hear an annoying pop song on the radio and days later you find yourself still humming the tune. Why does it seem like some things are so difficult to remember, and other things so easy? What's the difference?
Information that you have to consciously work to remember is known as explicit memory, while information that you remember unconsciously and effortlessly is known as implicit memory. While most of the information you find tends to focus specifically on explicit memory, researchers are becoming increasingly interested in how implicit memory works and how it influences our knowledge and behavior.
When you are trying to intentionally remember something (like a formula for your statistics class or a list of dates for your history class), this information is stored in your explicit memory. We use these memories every day, from remembering information for a test to recalling the date and time of a doctor's appointment. This type of memory is also known as declarative memory, since you can consciously recall and explain the information.
Some tasks that require the use of explicit memory include remembering what you learned in your psychology class, recalling your phone number, identifying who the current President is, writing a research paper, and remember what time you are meeting a friend to go to a movie.
There are two major types of explicit memory:
Episodic memory: These are your long-term memories of specific events, such as what you did yesterday or your high school graduation.
- Semantic memory: These memories of facts, concepts, names and other general knowledge information.
Things that we don't purposely try to remember are stored in implicit memory. This kind of memory is both unconscious and unintentional. This type of memory is also known as nondeclarative memory, since you are not able to consciously bring it into awareness. Procedural memories, such as how to perform a specific task like swinging a baseball bat or making toast, are one type of implicit memory since you don't have to consciously recall how to perform these tasks. While implicit memories are not consciously recalled, they still have an influence on how you behave as well as your knowledge of different tasks.
Some examples of implicit memory include singing a familiar song, typing on your computer keyboard, daily habits, and driving a car. Riding a bicycle is another great example. Even after going years without riding one, most people are able to hop on a bike and ride it effortlessly.
Here's a quick demonstration that you can try to show how implicit memory works. Type the following sentence without looking down at your hands: "Every red pepper is tantalizing." Now, without looking at your keyboard, try naming the ten letters that appear in the top row of your keyboard.
Since most students are good typists, you probably found it quite easy to type the above sentence without having to consciously think about where each letter appears on the keyboard. That task requires implicit memory. Having to recall which letters appear in the top row of your keyboard, however, is something that would require explicit memory. Since you have probably never sat down and intentionally committed the order of those keys to memory, it is not something that you are able to easily recall.
