Face Perception

Question 1

inferences we might be able to make from faces

Answer 1

-expression
-age
-gender
-race
-attractiveness
-trust
-competence
-intelligence
-political affiliation

Question 2

face recognition unit (FRU)

Answer 2

system/ model designed specifically to perform face recognition tasks

Question 3

how do FRUs work

Answer 3

they process faces into feature vectors (embeddings) which are representations of unique facial characteristics
stable identity characteristics are extracted which reduces noise

Question 4

pros of lab tests for face perception

Answer 4

-highly controlled
-systematic manipulation of experimental variables
-can establish cause and effect

Question 5

cons of lab tests for face perception

Answer 5

-highly simplified displays
-impoverished context
-does it adequately portray the real world?

Question 6

cons of field studies for face perception

Answer 6

-limited control
-cause and effect not clear
-‘one shot’ studies that are practically impossible to replicate
-for face matching, this requires access to security-sensitive environments - not possible for passport control

Question 7

pros of virtual reality for face perception

Answer 7

-can provide complex and increasingly realisticand immersive environments
-retains experimental control and allows basic and sophisticated measurements
-clear potential to bridge lab and field studies

Question 8

why is unfamiliar face identification difficult

Answer 8

within-person variability
