IB PSYCHOLOGY CASE STUDIES
1. Brewer and Treyens (1981)
*Answer√√ A: To investigate whether people's memory for objects in a room (oflce) is influenced by
existing schemas about what to expect in an oflce.
P: 30 university students who arrived individually to the lab.
Asked to wait in an oflce containing objects (eg, desk, typewriter, cottee- pot, calenders)
There were other incongruous items like skull and toy tops that did not go along with schemas.
After waiting for some time, participants were called into a room and and asked to write down what they could
remember.
R: Most participants recalled the schematic objects (eg, desks, typewriters)
Some participants reported things that should be there but weren't
The very unusual items were recalled.
2. Glanzer and Cunitz (1966)
*Answer√√ A: Tested the hypothesis that short term memory and long term memory are two separate
,stores in a free recall experiment.
P: 240 army enlisted men presented with a list of 15 words to memorise, IFR condition and DFR with counting down
activity.
R: P's recalled primacy and recency of list better,- serial reproduction curve.
3. Baddeley and Hitch (1974)*Answer√√ Working memory model: model of short term memory, active
store used to hold and manipulate information; has phonological loop, episodic butter, and Visio-spatial sketchpad
all controlled by the central executive
4. Loftus and Palmer (1974)*Answer√√ A: Find out if questions asked subsequent to an event can cause
a
reconstruction in one's memory.
P: 7 films showed, P's filled out questionnaire after each and gave an account of each. 1 Q. asked about the vehicle's
speed using one of these words: hit, smashed, collided, bumped, contacted.
R: Smashed had an avg. speed estimate of 40.8 and contacted 31.8 (lowest).
5. Rozenweig and Bennet and Diamond (1972)
,*Answer√√ A: Investigate role of environment on brain P: Rats in enriched and impoverished
environments
R
: Enriched rats had better developed cerebral cortex
6. Bremner (2003)
*Answer√√ A: Measure hippocampal volume based on stress P: MRI
scans and tests of veterans and sexual abuse victims
R: In these people, hippocampus was smaller and short-term memory loss demonstrated
7. Atkinson and Shiffrin
*Answer√√ multi-store model of memory
-serial position ettect
-amnesiacs
, 8. Wei (2015)
*Answer√√ A: To see whether lateralization was linked to post stroke disorder.
P:5507 patients brains were looked at using a CAT scan.
Large scale meta analysis of previous studies to identify a correlation between stroke location and risk of depression.
R:Relationship between right hemisphere and strokes/depression
Relationship NOT APPARENT in left hemisphere stroke patients
9. Clive Wearing
*Answer√√ Was a great conductor but got a virus and lost his hippocampus. can't make new long term
memories and his short term lasts between 7-30 seconds. procedural memory was not attected (he could still play
piano) but episodic was. hippocampus must control memory transfer from short to long term memory.
10. HM
*Answer√√ 27 years old and suttered severe epilepsy. cut out hippocampus. episodic and semantic memory
damaged.
