A higher liklihood that that action is occurring
1 of 25
Which is most likely?
Population coding
2 of 25
Do STS cells respond to action as a function of low level perceptual qualities e.g lighting size and position?
No
3 of 25
What is egocentric coding?
View-dependent
4 of 25
What is allocentric coding?
View independent
5 of 25
Which is the correct order?
Low level input -> View dependent -> View independent

(Pitcher et al, 2009) In a study using TMS and an object discrimination task, what resulted from disruption to LOA?
Object processing but not face or body processing

(Pitcher et al, 2009) In a study using TMS and an object discrimination task, what resulted from disruption to EBA?
Body processing but not face or object processing
13 of 25
What does observation of hand actions result in (Rizzolatti et al, 1996)
PET activity in STS and IFG
14 of 25
EBA and FBA respond best to?
Static bodies and body parts
15 of 25
STS best responds to?
Dynamic action
16 of 25
What do intentions imply?

In order to understand how other peoples mental representations differ from the reality of the world, what do you need to differentiate between?
Object of the mental state (what the mental state is about, goal of the action) and content of the mental state (how the mental state is represented)
21 of 25
What does the temporoparietal junction encode?
Representation of specific contents of mental states e.g TOM
