We encode information in our brain on different levels. The deeper level of analysis has been proven to be more effective to retain information. The level-of-processing was introduced by Fergus I. M. Craik and Robert S. Lockhart in the 70’s. They explain that the deeper level of processing is long-lasting and more elaborate than the shallow one. It creates a stronger memory trace. Shallow processing level leads to a fragile memory. The studies suggest that mere repetition or rehearsal doesn’t improve long-term memory as much as meaningful and elaborate analysis. There are three levels of verbal processing data. 1) structure 2) phonetic 3) semantic. Structure is about the general organization, phonetic is about the sounds, and semantic is about the meaning.
For example, when you meet someone for the first time and you try to learn the person’s name. It’ll be easier to remember if you associate the name with an emotion, an image that has a meaning to you to which you can relate. In the case you’re meeting someone named Samantha it will be easier if you try to remember that she is blonde like your best friend hair.
