Evidence 1:
Eyewitness testimonies are not reliable
Loftfus and palmers research suggested
post
event
information gets
incorporated
into the initial memory
Eg:
leading
questions lead to
memory
bias
and
verbs
used alter perception (
speed
estimates) essentially altering memory representation
THEREFORE: highlights that questions and
verbs
used alters
memory
which may led to an inaccurate
eye
witness
testimony resulting in false-imprisonment
Evidence
2:
Legal system: when a witness is
questioned
by an authorative figure, recollections of actual event memory is
distorted
Leading to retruals costing
£124
billion annually and
£44
,
000-£52
,
000
+ to keep someone in
prison
THEREFORE: the results of eye witness testimonies can have an
economic
backlash
due to money spent on possible wrongful convictions
Evidence 3:
Loftus and Zanni
“Did you see A broken headlight?” :
7%
reported yes
“Did you see
THE
broken headlight?” :
17
% said yes
THEREFORE: demonstrating subtle changes of wording can influence
memory
representation
