Interviewing Witnesses- recreating
faces by e-fit
- an e-fit is a picture of the suspect created by a
witness by identifying internal (eyes, nose, mouth)
and external (hair, face shape, ears) features
- in Bruces experiment, participants had to match
the celeb faces to their efit. They either had to
identify a full composite, an internal composite or an
external composite
- Bruce found that it was easier to identify external
features than internal…read more

Interviewing Witnesses- recreating
faces by e-fit
Evaluation of Bruce
E.V.- they were identifying faces of celebrities who
hadn't committed crimes, they had also probably
never seen the celeb in real life; and in real life
they wouldn't be matching a photo to a
composite, they'd be creating it from memory
Had a wide range of ages, so it proved that if it
was a familiar face (as it would be for younger pps) it
would be easier to identify than an unfamiliar face…read more

Interviewing Witnesses- factors
influencing accurate identification
- weapon focus refers to the witnesses attention on a
weapon which makes it more difficult for them to recall

they saw a man give the cashier a cheque, and in the
other they saw the man pull out a gun. They were then
asked to identify the man and rate their confidence
- she found that the pps in the cheque condition made
more correct identifications than the gun group
- eye fixation tech. showed that they stared at the gun
longer than the cheque…read more

Interviewing Witnesses- factors
influencing accurate identification
Evaluation of Loftus
reliability- standardised procedure, controlled
what they saw, used scientific eye fixation
machinery which cant be tampered with
Only saw slides of a taco restaurant, so they
showed less emotion than real life
Useful to for police to know that witnesses
may not be reliable if there was a weapon
because people look at the weapon more…read more

Interviewing Witnesses- cognitive
- 4 stages of C.I: 1. Report everything; 2. visualise the
crime scene; 3. go through it in reverse order; 4.
look at it from another perspective
- Fisher tested C.I. in the field, used interviews with
real witnesses- 16 detectives, 7 trained in C.I.- blind
assessors counted up amount of info taken from
- 63% more info was collected from cognitive
