- Busigny (2010), 52 year old woman, PS. damage to occipito and temporaral lobes, inability to recognise faces, but with help of peripheral cues she could.
- Delvenne (2004) NS aged 40, damage in occipito temporal junction. inability to recognise faces and objects.
- Bruyer (1983) reported the case of Mr W a farmer who could recongise indivudal sheeps and cows but not people.
- explanations
- acquired vs developmental: Duchaine. 2% of the population is affected by developmental pp.
- damage to a face processing unit: PS had damage to the FFA and OFA which indicated that's where pp underlies.
- holistic processing failure. farah suggested a continuum. pp results with a failure at the end of the continuum
- methodological issues- case studies look at unique individuals - cant generalise findings. association doesn't mean cause. difficult to reliably test. however case studies are rich in data
- ethical issues- privacy and harm to participants
- IDA- real world application- offers support knowing other people have prosopagnosia.
- ethical issues- privacy and harm to participants
- support for a unique face processor- Garrido et al. evidence challenging: Humphrey and riddoch. hollistic processing failure is not universal in prosopagnosics. supports B&Y model.
