1

What are the two approaches of face recognition?

Bruce and Young's theory which suggest face recognition is different to the recognition of objects and requires specific parts of the brain
Or
That we recognise faces like we recognise any other objects and no specific areas of the brain are used

2

What type of system is used in Bruce and Young's theory?

A holistic system involving interrelationships between different features

3

How does Bruce and Young's model work?

With a series of modules working sequentially and in parallel.

4

In detail, what is Bruce and Young's model?

Structural encoding stage begins when the brain identifies something that looks like a human face, then a mental representation of the face is produced. Alongside this basic processing takes place to decide if you're male, female, old, young ect
The face is then compared to the face recognition units which include every face we have stored. If we match the face we feel a sense of recognition
If there's a match we access the person identity nodes which store personal information about the persons name
We then retrieve the persons name

5

What happens in the structural encoding stage?

A mental representation of the face you are looking at is produced. Alongside this basic processing takes place to decide if the face is male, female, old or young

6

What is the first stage of Bruce and Young's theory of recognition?

Structural encoding takes place when we recognise something that looks like a human face and a mental representation of that face is produced. Basic processing takes place at the same time to determine if the face is old, young, make or female ect

7

What is the role of the face recognition units?

They hold every face we have ever stored in memory

8

What is the second stage of Bruce and Young's theory of recognition?

The face is then compared to the face recognition units which store every face we have ever stored in memory. If there's a match we feel a sense of recognition

9

What is the role of the person identity nodes?

To store personal information about the people of the faces we have stored

10

What is the third stage of Bruce and Young's theory of recognition?

If there is a match we then access the person identity nodes which are stores of personal identity about the people we have stored faces for

11

What is the fourth stage of Bruce and Young's theory of recognition?

We can retrieve the persons name

12

What are some of the processing systems which work alongside Bruce and Young's model?

Expression analysis
Facial speech analysis
Directed visual processing

13

What is expression analysis?

This makes inferences about someone's emotional state from their facial features

14

What is facial speech analysis?

This used visual information from the face when interpreting speech

15

What is directed visual processing?

This allows recognition of features of the face without necessarily identifying the person i.e if they gave a beard, or are wearing glasses

16

What is the basic principle of Bruce and Young's theory of face recognition?

That face recognition is different to recognition of other objects and requires specific parts of the brain

17

Who made modifications to the Bruce and young model?

Burton et al

18

What did Burton et al do?

Made modifications to Bruce and Young's model

19

What modifications did burton et al make to Bruce and Young's model?

There is no separate store for names
The decision whether or not the face is familiar is made at the person identity nodes instead of the face recognition units
The model has been demonstrated in a computer simulation

20

What studies support Bruce and Young's theory of face recognition?

Young et al
Young, Hey and Ellis

21

What were Young et als findings?

He found in ex service men who had missile wounds to the back of the head some were poor at familiar face recognition, others were poor at matching unfamiliar faces and some couldn't recognise facial expressions.

22

What do young et als findings suggest?

It suggests that different systems for different aspects of face recognitions. The ex service mens head injuries varied affecting which parts of recognition they struggled with

23

What is good about young et als findings?

They have good validity a because it is based on genuine cases of brain damage

24

Why does young et als research have good validity?

Because it is based on genuine cases of brain damage

25

What were young, hey and Ellis' findings?

They asked people with neurological defects to keep a diary of daily problems of face recognition. 1008 incidents were reported, but none involved putting a face go a babe without recalling details about the person. On 190 occasions a participant could remember some details but couldn't name them

26

How do Young, Hey and Ellis' findings support Bruce and Young's theory?

Because it follows the process of the model

27

What is a criticism of Bruce and Young's theory of face recognition?

The cognitive system in the model isn't explained very clearly. Bruce and young admit it is a bit of a 'catch all' not explain parts of the processing which isn't accounted for by other parts of the model
