Cognitive Flashcards
Schema theory
Multi store model of memory atkison and shiffrin 1968
Information - encoding - sensory memory - short term - long term - retrieval , capacity -duration * draw on paper
They working memory model baddeley and hitch 1974
Phonological loop, central executive , visual - spatial sketch pad,episodic buffer *draw on paper
Train image barlett
Showed participants a drawing of a subway train - asked to describe - proves that our memories are not ideal and could be influenced by leading questions
Henry molaison brain damage HM
Lost all short term memory - still has some long term - yet has procedural memory =muscle memory
Schmolck 2002
Contemporary study
Semantic memory -involving emotion
And how it relates to long term memory and damage to the medial temporal lobe
Sacchi et al 2007
Investigate doctored photographs of well know events
187 participants -31 male and 156 female mean age 22.2
Shown a Beijing photo standing on tainanmen square adding a crowed and police and a photo in rome with violence
Results -beijing seen the photo before 44%
Beijing seen the doctored photo 45%
Rome seen the photo before 45%
Rome doctored seen the photo before 24%
Schmolck procedure
Procedure-14 participants 3- had brain damage to the hippocampuso = medial temporal lobe
3-viral infections
8 participants were the control group - matched with patients with age and education
Schmolck accrual expirament
9 tests on long term memory tests with 6 sets of pictures with living things and man made
Schmolck results
Similar pictures -controls got all the answers right
HM scared 98%for living things and 100% for objects
Medial temporal lobe 85% living and 90% objects
Over all- 78%
Schmolck weakness and strength
Participants with brain damage can be expiramented on and not get bored
Small sample
High standardization
Some participants of different age might have poor memory
Ethical = not a disstressful task
Bartlett war of the ghosts grave
13 women and 7 men = around the same age - UK students and not reflective because in 1932 women
were rarely in universities = proves of reconstructive memory
Low population validity
Extraneous variables as the students could discuss what they heard
Participants excluded the part of the story they did not believe in
