Question 1

Intro

Answer 1

• Reject previous research
• Yin, demassi, Perrett
• Epilepsy
• Powerful but anatomically limited- doesn’t prove regions that are specific
• Contributes…

Question 2

para 1

Answer 2

facial recognition

• Occipitotemporal lobes role
• Anatomical localisation- unlike others
• Nasrs study- collateral sulcus
• Ffa->at->pfl= model for cognitive processing in facial processing
• Eliminate other areas and can build on structure- orbitofrontal cortex

Question 3

para 2

Answer 3

autism

• Diagnosis and assessment
• Model of disorder, molecular genetics and neurobio processes
• Schultz 2001- FFA= hypoactive= social disability
• Schultz 2003- FFA and ToM= important to pathobiology
• Autistics rely on areas that process objects- stumps social interaction and ToM
• fMRIs= ability to see which areas of the brain activate= clearer cognitive model and understanding

Question 4

para 3

Answer 4

prosopagnosia

• neurological disorder
• dysfunction or disruption in perceptual and memory processes on a variety of levels
• relate to FFA
• anatomic network of facial processing= right hemisphere (core system in facial recognition)
• fahr et al- developmental, early onsent or congenital proso= no activity
• counter evidence= normal activity
• more research but there is a link

Question 5

para 4

Answer 5

semantic memory

• semantic memory is…
• extensive research but no consensus
• binder et al 1992= meta analysis= memory is left lateralised and FFA involved
• Haxby et al 2000= significant peaks in FFA as LAT is responsible for semantic info for people
• Aid semantic dementia and suggest origins of SM= not localised

Question 6

nasrs

Answer 6

2012

collateral sulcus activated during facial perception tasks

Question 7

Schultz (1)

Answer 7

2001

FFA= hypoactive which leads to social disability

Question 8

Schultz (2)

Answer 8

2003

FFA involved in ToM which is important to pathobiology

Question 9

processing objects instead of faces =

Answer 9

issues with social interaction

ToM

Question 10

fMRI scans

Answer 10

create clearer cognitive model and understanding

Question 11

Fahr

Answer 11

developmental,early onset and congenital proso= no activity

Question 12

counterarguement for Fahr

Answer 12

normal activity

Question 13

binder et al

Answer 13

1992= meta analysis of semantic tasks= left lateralisation of semantic memory and FFA involved

Question 14

Haxby et al

Answer 14

2000

significant peaks in ffa and lat- responsible for semantic info on people
