Continue talking about memory and talking about something new Alzheimer’s Disease.
Probably not on the test, bur very interesting. 1 out of 2 people above 85 get Alzheimer’s, the other person
is most likely to get cancer.
Changes in personality.
Can enhance longterm memory encoding by expanding short term memory abilities. Other tricks you can
do to enhance performance of shortterm memory.
Maintenance rehearsal: you can keep things in your shortterm memory by rehearsal. Repeating
sentences. Pegs are more helpful though, assign a meaning to something and helps you remember it
Mnemonic devices: ex. Trying to remember James Watson Skinner:
Clustering and chunking: phone numbers, years.
Narrative: Make up a story. Darwin used a boat, Skinner used a box, Watson..
Acrostics: Just Who’s Seminal?
Longterm memory: testing and type.
Recall – fill in the blank
Recognition – multiple choice
Relearning – how much faster the second time? How longer does it last if you learned it a second time? Overlearning – how much longer it lasts if done over? Redo something over and over again. Ex. Typing.
Explicit – available by conscious effort.
Implicit – not available through conscious effort.
