Cognitive Psychology - Levels of Processing

HideShow resource information

The Levels of Processing model of memory was put forward by Craik and Lockhart in 1972. Instead of concentrating on the stores / structures involved, this theory focuses on the processes involved in memory. They proposed that memory is just a by-product of the depth of processing of information and there is no clear distinction between short term memory and long term memory.

Depth: The meaningfulness extracted from the stimulus rather than in terms of the number of analyses performed on it.

Shallow Processing

Takes two forms

  • Structural processing: When we encode only the physical qualities of something.
  • Phonemic processing: When sound is encoded.

Shallow processing only involves maintenance rehearsal (repetition to help us hold something in STM) and leads to fairly short-term retention of information. This is the only type of rehearsal to take place within the multi-store model.

Deep Processing

  • Semantic processing: Happens when we encode the meaning of a word and relate it to words with similar meaning.

Deep processing involves elaboration rehearsal which involves a more meaningful analysis of information and leads to better recall.

Research Study: Craik and Tulving (1975)

Aim: To investigate how deep and shallow processing affects recall.

Method: Participants were presented with 60 words about which they had to answer one of three questions - some questions required deep processing (semantic), others required shallow processing (structural or phonemic). Participants were then given a list of 180 words. They had to pick out the original 60.

Results: Participants recalled more words that were semantically processed.

Conclusion: Semantically processed words involve elaboration rehearsal and deep processing which results in more accurate recall. Phonemic and structural processed words involved shallow processing and less accurate recall.
