150 uni students saw a video of a car crash.
Condition 1: asked about a barn. Condition 2: weren't
asked about a barn. 13 condition 1 said they saw a
barn 1 week later, 2 condition 2 said they saw a barn
Loftus and Zanni
100 students ere shown a video of a car crash. Condition 1: 'Did
you see the broken headlight?' Condition 2: 'Did you see a broken
headlight?' 15% of condition 1 said yes, 7% of condition 2 said yes
List
Developed 8 events that were likely to show up in a shoplifting
scenario and then asked people to rate the likelihood of them
happening. New participants watched a video of a shoplifter and
a week later they were asked what they saw. They recalled the
most likely events whether they had occurred or not.
schemas
Anxiety
Loftus
Condition 1: heard talking and a man with a pen and oil in his hands.
Condition 2: heard arguing and a man with a knife and blood on his
hands. 49% of condition 1 could identify the man, 33% of condition 2
could identify the man
weapon focus
Loftus and Burns
Participants were shown a video of a bank robbery. Condition 1: a boy
is shot in the face. Condition 2: boy runs across the screen. 4% of
condition 1 remember the number on the boys shirt, 27.9% of condition
remember the number.
Yuille and Cutshall
Real life. Gun shop robbery in Canada, witnesses
were interviewed five months later and their testimony
was found to be very accurate.
Age
Poole and Lindsay
Children aged 3-8 took part in a science
demonstration and were then read a story.
Only the older children were able to distinguish
between the experiment and the story
Flin
Children and adults were asked questions about an
incident 1 day and 5 months after if happened. Children
weren't able to remember much after 5 months.
Anastasi and Rhodes
Tested 3 age groups. Each participant was shown photographs of a mixture of age
groups. They were later shown 48 photos, half of which they had already seen. They
were asked to identify these photos.The participants were better at recognising
photographs of their own age groups.
Cognitive Interview
Context restatement
recall the scene, the weather,
what you were think and feeling
recalling how you felt and the context enhance
recall (these details act as cues to recall)
Report everything
report every detail you can even
if they seem irrelevant or trivial
witnesses don't always realise how
important some details are
Changed perspectives
describe the event as it would have
been seen from different viewpoints
encourages many retrieval paths
Reverse order
describe the event in
reverse order
when events are recalled in forward order,
witnesses reconstruct based on their schemas. if
the order is changed they are more accurate
Memory Aids
Method of loci
where material to be remembered is placed mentally
in familiar locations. it can be recollected by
revisiting the locations mentally when it is required
Acrostics
using the first letter of each word
to create a new sentence
Narrative stories
remembering information by linking
together all the items that need to
be remembered through a story
Working
Memory Model
Phonological loop
Articulatory loop
Inner mouth
Phonological store
Inner ear
Responsible for encoding acoustic data.
Holds verbal information
Central execuive

allocates attention to it's two slave systems
limited capacity
Visuo Spatial Sketchpad
Inner scribe
acts as a rehearsal mechanism
Visual Cache
responsible for visual encoding.
acts as an inner eye
Multi-Store Model
Clive Wearing
he was brain damaged and can no longer make
new memories. he is unable to rehearse information
so it can't be transferred from STM to LTM.
