Which Levels of processing theory suggests that longer lasting memory codes are the result of level of processing?

Levels of processing theory suggests tha there are three levels of processing

1. Shallow Processsing - Structural Encoding: where you emphasize the physical structure of the stimulus (i.e. caapitalization)
2. Intermediate Processing - Phonemic Encoding: where you emphasize what the Word sounds like (i.e. rhymes)
3. Deep Processing - Semantic Encoding: where you understand the meaning of the stimulus (i.e. definition of)

According to the levels of processing theory, the longer lasting memory codes are a result of Semandtic Encoding which is the deepst processing level and where you are required to understand the stimulus.
