Deep Processing
Deep processing refers to one of the extreme ends of the level of processing spectrum of mental recall through analysis of language used. Deep processing requires the use of semantic processing (how words work together to create meaning) which creates a much stronger memory trace.
On the other extreme of the continuum is shallow processing which requires only phonemic and orthographic analysis (how the sounds are connected to make words). An example of this might be the difference between reading new material where you are concentrating only on recognizing the words, rather than focusing on the meaning of the sentences and paragraphs.
