  • Face Recognition- Holistic Theory
    • Young et al
      • Supports the sequential nature of facial recognition
      • Participants kept a diary to note when they struggled to recognise a face
      • There were no reports of naming people if the participant was given no other information but there were 190 cases people gave a description without a name
      • Better than Shepard et al
        • Took place in the real world= more ecologically valid
        • More longitudinal
    • Walton et al
      • 12 faces of new mothers and 12 strangers
        • Matched on hair and eye colour, hairstyle and complexion
      • Babies as young as 1 day kept their mothers on screen longer
      • Children controlled how long the image appeared by increased sucking on a dummy
    • Evaluation
      • Lots of empirical evidence
      • Flude et al- Participants with brain damage could name a persons occupation 85% of the time but name them only 15%
      • Although prosopagno-sia patients do not conciously recognise faces, use of GSR shows they do subconsciously recognise faces
        • Both FRU and PIN's were activated
      • Lacks detail for unfamiliar face recognition
    • Key Points
      • Face recognition develops in infancy
      • Lighting & motion can effect recognition
      • Good lighting and motion can improve recognition which creates problems for face recognition software
      • Specialist neurons deal with face recognition
    • Bruce et al
      • A familiar face is structurally encoded. This means that a description/ representation of the face is produced
        • This activates Face Recognition Units (FRU's). Each face known to the viewer has a FRU. Each FRU contains structural information about the face
          • This activates Person Identity Nodes (PIN's). This contains semantic information about the person such as normal context, occupation, interests etc
            • This activates Name Generation. Information about a person's name is stored separately from other information and so is accessed last
