Long term memory Flashcards
What is long term memory/what does it do?
- Holds an enormous amount of information - eg who we are, how we walk, use grammar etc
- Normally very efficient
- Has different components eg semantic/episodic
What are the 3 logical stages of LTM?
- encoding
- storage
- retrieval
Who developed the Levels of Processing model?
Craik and Lockhart (1972).
What is the general theory of LOP?
That the more levels a stimulus went through, the more likely it was to be remembered.
Different types of rehearsal lead to different types of encoding.
What are the 2 types of rehearsal within LOP? Which then lead to different levels of encoding.
- Maintenance rehearsal
- Elaborative rehearsal
What is maintenance rehearsal?
- Simply repetition
- It prevents forgetting but does not lead to LTM storage.
What did Craik and Watkins find about the relationship between maintenance rehearsal time and the level of learning?
There is no relationship between the two.
What is elaborative rehearsal?
- encoding information in more meaningful ways
- leads to long term learning due to deeper encoding.
What are the 3 levels of processing?
- shallow
- phonemic/auditory
- semantic processing
Describe shallow (visual) processing.
What a word LOOKS like. eg is it in capital or lower case letters?
Describe phonemic/auditory processing.
Making a judgement about the sound of each word - eg does it rhyme with x?
Describe semantic processing.
Making a judgment about the words meaning. eg Does the word fit into the sentence - The man ate his _____?
From their study on levels of processing (recall of words through different methods of processing) what did Craik and Tulvig (1975) find?
Words that had been processed at the deepest level (semantic) which are based on meaning, were remembered BEST.
What did Kapur et al (1994) find about brain regions and processing?
Semantic processing activated more brain regions than shallow processing. This greater brain activity is associated with better memory.
What view did Morris, Bransford and Franks (1977) introduce with regards to LOP?
That retrieval is just as important as encoding.
