Memory- Accuracy of eyewitness
testimony: Misleading information
Stages of eyewitness memory :
Eyewitness testimony is the
information in which a witness of
an event provides evidence in
court
1:Witness encodes details of the event and people involved into their
LTM (Encoding may be partial & distorted, particularly if the event
happened quickly, at night or involved violence
The Witness retains information for a period of time (Memories may be lost or modified during
retention- most forgetting takes place within the first few minutes and other activities may
interfere with the memory between encoding & retrieval
The witness retrieves the memory from storage (the presence/absence of
retrieval cues, or nature of questioning may affect accuracy of recall)
Leading question is a question asked that suggests to
the witness what answer is desired or leads them to
the desired answer
Post-event discussion
Conversions between co-witnesses or interviewer and the eyewitness
after a crime which can potentially shape the witness' memory of the
event
Conformity effect : Is when co-witnesses of an event
discuss what has happened in the event and come to
an overall consensus on what happened in the event
Fiona Gabbert & Colleagues (2003) invested pt.s in pairs were each pt.s
watched a different video on a same event, viewing unique items. Pairs in 1
condition were encouraged to discuss the event. 71% of witnesses who
discussed the event went on to recall items from the discussion
Repeat Interviewing : Is information said from an
interviewer that shapes the witnesses recollection
of events .
La Rooy et al. (2005) Used leading questions in which
alters individuals memory for events especially when
children are involved
Loftus & Palmer (1974) carried out 2 studies (First whether a
car hit another car (verb manipulated) (Second whether a car
crash involved glass or not)
