- Bodamer 47
- people w anomia - same only for faces - prosopagnosia
- De Renzi 86
- are faces harder?
- De Renzi 87
- Prosopagnostic patient - could disting dogs, coins, breeds - used colour and featural info?
- Bruyer 83
- Mr W - recog cows but not faces
- Assal 84
- MR X could recognt cows or faces
- McNeil & Warrington 93
- WJ - prosopagnosic, could recog sheep, learn sheep not faces
- Young 93
- 32 ex-servicemen w brain lesions ; face id; fam decision; simultaneous face matching; sequential face matching; expression matching; expression recog
- RH lesion
- unfam faces only deficit
- 5 LH lesion
- expression deficit
- Bruce and Young
- Valerie - right temp lobe prob - prosopagnosic
- Young Hellawell & Dehann 88
- DH : forced face to name matching ; associative priming- fam judge RT to name following face prime
- FU- PIN = disrupted so only ltd activation but enough to prime
- Bauer 84
- famous and non famous but no capgras
- Ellis & Young 90
- Proso - ventral damage, Capgras- dorsal damage
- Capgras
- replaced by imposters
- Fregoli
- person diguising self
- Intermetamorphosis
- rapid appearance change - look like someone else; occur through epilepsy
- Ellis 97
- SCR to fam face- amy, SCR to tones cingulate
- Ellis 2000
- capgras do show associative priming
- Covert recog
- autonomic recog
- Hirstein & Ramachandran 97
- Patient imposter- not when phoned
- Lewis 2001
- patient HL : capgras for faces only
- Prob w capgras-
- prob to prior PIN level
- Capgras 23
- Don't normally show SCR response
- David 93
- capgras allows us to see probs w cog models
- Ellis and de pau 94
- capgras result from neuro, toxic, other organic
- De Pau 94
- Traditional explanations of capgras - hard to explain
- Ellis 96
- Object capgras
- Haxby 2000
- Prosopagnosia- face recog after loss of right inferotemporal region
- Tranel 95
- failed to respond to other emotional stim
- Renault 89
- CNS measures
- Proso
- Intact overt & absence covert
- Ellis and Young
- 9SCRs 2 low tone - capgras normal response: therefore not CNS
- Ramachandran
- Telephone OK
- Routes to recog
- ventral- lontitudinal fasciculus btw visual cortex and limbic system
- Ventral
- Obj perception- shape and colour
- Dorsal
- Spatial location/ place
- Breen 2000
- if saw familiar chair vs chair!
- Coltheart 97
- Breen doesn't describe how to fail to receive confirmation; delusion
- Farah 93
- info reintergrated: data identified by comparing joint info
- James 50
- When know person have automatic "glow"
- Stone & Young 97
- Bias in favour of observational adequacy
- Young 99
- Delusion manifest after abnormality- attribution stage therefore change in SCR
- Bruce and Young model
- see pic
- Young and Burton 99
- Lesions lead to graded degredation of info processing
- Critchley 2000
- SCR correl w amy
- Tranel 85
- SCR after faces
- Ellis 93
- Covert recog= SCR - prosopag
- Visual imparement
- see pic
- Tasks to learn proso capg
- name learning, face interference, name face pairing
- Bauer 86 - evidence for dual route
- autonomic recognition not found in apperceptive patients - unable to activate stored visual info for face
- Tranel &b Demasio
- Covert recog in prosopag w SCR
- Damasion & Damasio 95
- unsure if diff btw appercept due to anatomical localisation or extent of lesion
- Bauer, Verfaellie 88
- 80% accurate of face match - face perception intact-
- Tranel & Damasio 98
- Associative prosopag- normal SCRs
- Baron cohen 2000
- not only pathway for autonomic response - SCR can come from frontal lobe lesions
- Ungerlider *& Mishkin 82
- Visual pathways: lesion studies, ventral and dorsal p-ways, lesion inferior temp lobe, visual deficit, 2d vs 3D, parietal lobe lesions - no deficit, landmark lesions
- Breen, Coltheart & Caine 1999
- Pins or affective come from FRU
- Bauer
- 2 routes to face recog
- Milner & goodale 95
- amy holds emotion info
- Milner 91
- DF: visual agnosia : could reach for stuff : hand slot etc : not able to say where put hand in slot - unable to percieve orientating
- Goodale 94
- RV: couldn't describe obj shape - motor function ok
- Tranel & demasio
- Show patient, had SCr from familiar objects
- Match face
- Ventral temporal lobe
- Prosopag
- Ventral pathway prob
- Herstin & Ramachandran 97
- spoke to parents on phone
- Farah 90
- Prosopags- weak SCR- long rctn time, covert recog - not normal recog - tested covertly
- (Burton et al., 1991
- published, a key question has been whether overt and covert face recognition are
- Bobes(2003)
- same impairment that causes prosopagnosia may explain an impairment in sequential (but not simultaneous) matching of unfamiliar faces
- Schweinberger& Burton 2002
- Bobes used no time delay between the sequentially presented faces
- Schweinberger& Burton 2003
- Bobes- critisism, still don't know whether unfamiliar andfamiliar faces are processed by the same mechanisms.
- Schweinberger& Burton 2004
- Bobes-it would have been interesting to see whether ERP findings would support a normal timing of familiar face perception in FE
