Flashcards in Bruce + Young's Theory of Face Recognition - Perception Deck (19):
According to Bruce and Young what is face recognition?
A quite holistic system, involving the inter-relationships between different features
- A series of modules that work sequentially and in parallel
What is the first step in facial recognition?
Identifies human face
- Structural encoding + mental representation of the face is produced
- Basic processing e.g. male or female
What is the second step in facial recognition?
Face compared to face recognition units
- Includes every face stored in memory
What is the third step in facial recognition?
If theres a match = access person identity notes - personal info of those stored
What is the fourth step in facial recognition?
Retrive persons name
What is expression analysis?
Makes inferences about someones emotional state from facial features
What is Facial speech analysis?
Uses visual info from the face when interpreting speech
What is Direct Visual Processing?
Allows recognition of features of the faces without identifying the person
How is the Cognitive System used?
Additional info that may aid recognition
How does N/N relate to Bruce and Young's theory?
Theory suggests facial recognition is an innate system but we develop whats needed for it through life e.g. person identity notes (nurture)
What did Young et al do?
Studied face perception in ex-servicemen:
- Men had missile wounds to the back of the head
What did Young et al find?
- Some poor at familiar face recognition (face recognition units not working)
- Some poor at matching unfamiliar faces (structural encoding not working)
- Others couldn't recognise facial expressions (expression analysis not working)
What does Young et al's study show?
Supports the theory as shows there are independent systems for different aspects of face recognition.
How does N/N relate to Young et al's study?
Nurture = caused prosopagnosia, nurture can have a big effect
How does PAS relate to Bruce and Young's study?
Scientific research carried out under controlled conditions. But also valid as genuine cases of brain damage.
What did Young, Hey and Ellis do?
Asked participants to keep a diary of problems with facial recognition
What did Young, Hey and Ellis find?
- 1008 incidents BUT not one involved putting a face to a name without recalling some details about the person
- 109 occasions where details not names were remembered
What does Young, Hey and Ellis' study show?
Supports the theory as every time people generated a name they first came out with a fact
