How we change what others think, feel, believe and do
When you are storing memories there are a number of factors that increase the likelihood of later recall of the memories.
The depth of a memory trace depends on the extent of meaning that you extracted from it. If something is particularly meaningful then it is more significant to you and you are more likely to be able to bring it back to mind.
Depth is extended by the amount of processing performed on an item. If you think harder about it before you commit it to long-term memory, then you will be able to recall it more easily.
A memory that is different or unique in some way from other memories is also easier to recall.
Craik and Lockhart (1972) identified the notion of depth. Craik and Tulving (1975) showed how elaboration with experiments such as getting subjects to fit words into blanks in complex sentences.
Eysenck (1979) added the notion of distinctiveness. Memories that are similar can overlap, making it necessary to distinguish them by finer criteria. If the whole thing is different then it needs a different memory trace through the brain.
