HOLISTIC THEORY

FRU'S - REMEMBERING STRUCTURE OF THE FACE

PIN'S - REMEMBERING INFORMATION ABOUT THE PERSON

Prosopragnosia - can't recognise familiar faces

Capgras syndrome - people think they've been replacede by doubles

SCRAMBLED FACES -PUTTING FEATURES IN DIFFERENT AREAS OF FACE

PAIRING HALVES OF FACES - HALF OF EACH

INVERTED FACES - UPSIDE DOWN

COMPOSITE SYSTEMS

PHOTO-FIT = JIGSAW LIKE PIECES SLOTTED TOGETHER INTO A TEMPLATE

E-FIT = A COMPUTERISED VERSION OF PHOTO FIT

EVOFIT = COMPLETE FACES ARE GENERATED THEN 18 FACES ARE GENERATED

''ABSOLUTE JUDGEMENTS''

simultaneous line up: all suspects are lined up and the witness must compare them to make an absolute judgement of who they think is the criminal

sequential line up: witness is shown suspects one at a time so that they can see which one has the most likeness, however it can be difficult because they never know if the next person will look even more alike

ESTIMATOR VARIABLES

WEATHER CONDITIONS - if it is a foggy day, it will be more difficult for the witness to see the criminal which will then cause difficulty in later identification for them to make an absolute judgement. however if it was a sunny or clear day, then it will be easier for the witness to get a good description of them

WEAPON FOCUS - if a witness is so shocked by a weapon and that is all they can focus on, it means they can miss other parts of the crime which will later be needed as evidence. this gives them a weaker account of what happened therefore may be less likely to capture the criminal.

COGNITIVE INTERVIEW

GOES MORE IN-DEPTH THAN A NORMAL INTERVIEW

  • recreating the context of the crime
  • report everything even if it seems irrelevant
  • recall the incident in different orders
  • report from other perspectives (what others may have percieved)

+ reduces post event contamination

+ takes place asap after the crime

- the increase of incorrect information as well as correct is a concern

FLASHBULB MEMORY

  • INFORMATION ABOUT THE PEOPLE AND PLACE
  • EMOTIONS FELT BY SELF AND OTHERS
  • PERSONAL CONSEQUENCES OF EVENT

A flashbulb memory leaves a vivid memory of an event, even if it was public or personal, for example 9/11. That was a tragedy that shocked the world, therefore it is likely that many people have a flashbulb memory of when they discovered it had happened.
