Q

Describe the Face Recognition Unit (FRU)

A

Face recognition units (FRUs) contain information about the faces you know. If the encoded information has a reasonable match with this information then the FRU is activated and triggers the next node, the person identity node.

Q

Describe the Person Identity Node (PIN)

A

PINs contain information about a person;s identity, such as their occupation, their interests and so on. Once a person’s indentity is established, then a person’s name can be retrieved (name retrieval unit NRU)

Describe the Name Retrieval Unit (NRU)

A

The NRU is the unit which can retrieve a person’s name once they have been identified.

Q

Describe Young et al’s findings

A

Young et al. conducted a diary study where they asked 22 participants to keep a record of the mistakes they made when recognising people over an eight-week period. they found that many errors involving recalling information baout a person but no recalling a name without some relecant personal identity information. the pattern of these errors is explained by the serial nature of the model (PIN comes before NRU).

Q

Describe Youn et al.’s other findings

A

Young et al.’s found that pas predicted participants were faster at identifying whether a particular face was that of a politician than they were at identfying the politician’s name.

Q

Explain the strengths and limitations of Bruce and Young’s Theory

A

The main strength of the model is that it generates precise predictions that can be tested, and that further our knowledge of face recognition. The model also spells out the differences in the way familiar and unfamiliar faces are processed. However, the details of unfamiliar face processing are vague and other components of the model, such as the cognitive sustem are also not clearly specified.

Q

AID: Real World Application

A

The study of face recognition has important applications, for instance in the production of machines that will recognise faces for security and in assisting police to produce accurate eyewitness records. Such systems have been developed in conjunction with psychological research on how people recognise faces.

Q

Explain how the Thatcher effect supports Bruce and Young’s Theory

A

The Thatcher effect is that when a face is upside down, configural processing cannot take place (processing where features viewed are related to each other rather than feature-by-feature detection). This means that minor feature differences are more difficult to detect and supports the notion of a unique face processor.
