face vs name for naming fam occuapt
face= fame fastest, name slowest
name= name fastest, occupation slowest - Brennan 90
-
TOTT state :
rpt quest who last US president
show pic
give initials - most resolved
Supports Bruce and Young prediction - Hanley 98
-
face and voice
fam only
unfam
named
fam and occup (not name) - voice recog
-
more fam only
VRU harder to activate?
Give fave and voice = more recog
More routes to PIN activation - Hanley & Turner 2000
-
Faces recog easier or pref access PIN/NPU/SIU
blurred faces = voices
faces easier to recog not pref access - Moore & valentine 98
-
Tinme to name famous face= affected by fam and A0A and frequency (not D or name length
(poor method) rated fam so may be biased by currency of fame - Lewis 99
-
soap faces
Ctrld freq
AoA & Currency
Current, f and A0A early = faster did soap from
AOA + freq = familiarity - Burton Bruce and Johnson 96
- IAC
- Burton, Johnston & ellis
- IAC accounts for prosopagnosia
- FRU
- match stored reps to fam faces
- PIN
- detect familiarity
- SIU
- semantic units containing info
- Links
- can be inhibited or excitatory
- Threshold
- If threshold reached= activation
- Prosopagnosia
- face neither familiar or has semantic info
- Morrison 2001
- attention prompted by expter; not spontaeous - must be due to attention!
- POR
- must be an increase in activation in PIN; results in right face being recognised
- Pins to SIU
- multiple pins (8 faces); increased threshold for SIUs to activate
- attention
- not ususally specified in IAC model
- SIU-PINS
- if enough stim in SIUS from individual pins, - reaction should increase the threshold of the PINS (reactivation) therefore SIUs increase threshold and name retrieved
- Stone & Valentine 2003
- if SIU activated proso would act spontaneously state name
- Sergent & Signoret 92
- in these studies prosos may have may have recog individual faces as occupation links were made;
- Valentine and stone
- attention only in context of POR - they find it incomprehendable; impact on other components not considered
- Diamond 94
- patientnot allowed to be spontaneous - problem w method
- dehann 91
- study-spontaneous w prosopag and face recog
- Valentine & Stone 2003
- If Threshold reached and feedback to pins ; pins inhibit within PINS -not activated before - presentation of each face - one by one increased activation of pins; therefore PINS activated by one face
- Prosos able to face recog
- generating shared occupation provides sufficient activation to raise the SIUs above threshold
- Learning new faces
- Jets and sharks
- McClelland and Rumelhart 98
- IAC-I (interactive)
- NOU
- name output units
- NOU explains
- time taken for familiarity, occupation, name, decisions, tot, covert recognition, semantic repetition priming
- Associative and repetition priming in IAC
- charles and diana
- SIU linked to Diana's PIN
- Therefore quicker to recog w associative priming (latent activation
- Bruce & Valentine
- Face primes for face, name primes for name, no cross priming with later recog
- Burton 90
- repetition priming like synapitic plasticity
- Hebbian IAC
- Inhibition proportionate to activation - eventually reaches full inhibitioin -1
- Stevenage and lewis 2002
- recognition task acquisition data over time of new faces - twins lizzie or rosie - compared w computerised IAC ; was able to aquire twin names sigmoidal curve
- Bredart 95
- names and semantic in sep pools
- Burton 94
- indicated that hebian synapse should be used for learning
- see pic
- Ellis, Burton, Young & Flude 97
- Strengthening at FIU and FRU and FRU - PINS = help face recognition priming
- Present all features
- prime whole face
- Rumelhart Hilton Williams 86
- Golbal modification of weights in network therefore unale to recog error
- Lewis 2002
- golbal modification of weights in network difficult to apply to ICA
- Sergent & Poncet 90
- didn't name occupation unprompted - delay btw recall & time to recall , but shared occupation activations; may have increased SIU above threshold=recog
