CRAIK AND LOCKHART 1972

1. Why do we remember some things and not others? When we see a stimulus in the environment we automatically process it. The way we process it depends on the type of information and how relevant it is.

2. TYPES OF REHEARSAL-MAINTENANCE REHEARSAL rehearsing information to preserve it for a short amount of time, but is unlike to result in a strong memory being established.

   • ELABORATIVE REHEARSAL-Deeper consideration of the informatioften by giving it more meaning, and is likely to result in a more durable memory being made

3. Memory is a by-product of the way information is processed

4. AIM

   • To determine whether recall is affected by the way information is processed

5. METHOD

   • P's were required to answer yes or no to a question about a word shown
     • There were 3 types of questions asked that determined how deeply a word was processed. 1. structural (physical e.g upper or lower case) 2. Phonetic (sound e.g does cat rhyme with rat) 3.Semantic (meaning)

6. RESULTS

   • 70% Semantic, 36% Phonetic, 15% Structural

7. CONCLUSION

   • Word processed at a semantic level were more likely to be recalled due to deeper processing
