face recognition Flashcards

1
Q

Bruce and Young’s model of face recognition properties

A
  • modular: different activities processed independently
  • distinct pathways for recognising familiar faces vs recognising expression, etc
  • parallel pathways: dealing with facial expression, facial speech, visually derived semantic information (e.g. sex, age, race)

Q

Bruce and Young’s model of face recognition components

A

familiar faces activate: the facial recognition unit (FRU)
FRUs are linked to person identity nodes –> gateways to semantic information about the person
PINs are linked to name generation

Q

semantic priming

A

a face is responded to faster if it follows a closely related face (e.g. Charles –> Diana
no means to account for this using the Bruce & Young model

Q

IAC model

A

concept and category learning
semantic info is ‘pooled’
knowledge is represented in pools
relationships are represented by connections between pools
within pools: mutually inhibitory
between pools: mutually facilitatory

Q

apperceptive agnosia

A
  • able to move around and negotiate obstacles without difficulty
  • grasp reveals knowledge about size and shape
  • unable to carry out basic copying and matching
  • failure occurs at stage 2 ‘shape representation’

Q

associative agnosia

A
  • copying and matching skills are intact
  • unable to NAME object despite intact knowledge
  • failure to access knowledge about the objects
  • damage at stage 3 ‘object representation’

Q

prosopagnosia

A
  • inability to recognise faces
  • usually right inferotemporal lesion
  • unable to recognise faces through visual input but recognition by other modalities remains intact –> iduviduals can be recognised by their voices
