First a quick look at the levels of processing approach to memory:
This theory is more so about processing information than simply storing it as is common with the short term / long term memory. With the levels of processing, there are three:
1. Structural Processing - the way information appears or looks physically
2. Phonemic Processing - the way it sounds
3. Semantic Processing - how we encode the meaning of a word and relate it to similar words
#1 and #2 are seen as "shallow processing" while #3 is "deep processing" which is said to be better for long term memorization.
So now, we need to look at study strategies which would use the three processes above.
1. Structural processing - looking at the words, remembering how they looked, the type face, bold, italics, capitals or lower case
2. Phonemic processing - would be to take information and try to rhyme certain keywords with others to remember via the sound of the word.
3. Semantic processing - take the word and place it in a sentence or story to remember the meaning, associating it with other synonyms (similar) or perhaps even antonyms (opposites).
