Answer 1

A condition characterised by difficulty to recognise faces

Question 2

What are the two main types of prosopagnosia?

Answer 2

Congenital and Acquired

Question 3

What is another term for Congenital Prosopagnosia?

Answer 3

Developmental or Hereditary Prosopagnosia

Question 4

How is Congenital Prosopagnosia defined?

Answer 4

Failure to develop face recognition ability without neurological illness or brain injury

Question 5

What is the prevalence rate of Congenital Prosopagnosia according to Kennerknecht et al. (2006)?

Answer 5

2.5%

Question 6

What are the symptoms of Congenital Prosopagnosia?

Answer 6

Irritation/uncertainty in recognizing faces, failure to recognize familiar faces, wrongly recognizing unfamiliar faces

Question 7

What evidence suggests a genetic basis for Congenital Prosopagnosia?

Answer 7

All 14 participants who had CP had family members with CP

Question 8

When does Congenital Prosopagnosia typically onset?

Answer 8

In childhood

Question 9

What structural difference is associated with Congenital Prosopagnosia?

Answer 9

Differences in the Fusiform Face Area (FFA)

Question 10

Is Congenital Prosopagnosia associative or apperceptive?

Answer 10

Associative

Question 11

How is Acquired Prosopagnosia characterised?

Answer 11

A heterogeneous disorder with variability in symptoms and lesion sites

Question 12

What are the two types of Acquired Prosopagnosia?

Answer 12

Apperceptive and Associative

Question 13

Describe apperceptive and associative prosopagnosia.

Answer 13

Apperceptive - failure to perceive face structure. Associative - failure to link face with identity or semantic knowledge.

Question 14

What brain areas are linked to deficits in face processing in Acquired Prosopagnosia?

Answer 14

Occipital Face Area (OFA) and Fusiform Face Area (FFA)

Question 15

What is the primary treatment approach for Congenital Prosopagnosia?

Answer 15

Behavioural strategies

Question 16

What are some compensatory techniques for individuals with prosopagnosia?

Answer 16

Relying on non-facial cues like voice, clothing, or distinctive features

Question 17

What factor may influence the effectiveness of interventions.

Answer 17

Enhanced neural plasticity

Question 18

List three limitations of treatment for congenital prosopagnosia.

Answer 18

1. Not all individuals benefit equally from interventions.
2. Limited generalisation to everyday situations.
3. Children may have a greater capacity for improvement due to enhanced neural plasticity.

Question 19

What strategy did Powell et al. (2008) find most effective for improving face recognition in acquired prosopagnosia?

Answer 19

Attending to distinctive features

Question 20

Why might it be difficult to restore normal face processing in Acquired Prosopagnosia?

Answer 20

Face-selective mechanisms may not be easily replaced by general object processing mechanisms

Question 21

What is the key difference between Congenital and Acquired Prosopagnosia in terms of onset?

Answer 21

Congenital occurs from birth, while Acquired results from brain injury or illness
