What is evidence for the Dorsal and Ventral stream?
If you remove the temporal cortex or produce a lesion on the ventral stream of a monkey it cannot recognise the object, if you do it to the parietal/dorsal stream they cannot recognised where something is and cannot solve a spatial test

What does the fact damage to the dorsal stream doesn't affect the ventral stream mean?
That there could be a double dissociation

What is the purpose of the dorsal stream?
To support action, we need to know where objects and how to plan movements, gives us an egocentric frame of reference and short-lived representations.

What is affordance?
What the environment offers to acting organisms. Can you have a relationship between yourself and an object, can we interact with it

What do affordances represent?

Space around your body
23 of 27
What is extrapersonal space?
Space around the peripersonal space, space which is not near you

What is the difference between reachable and non reachable space and congurent and incongruent?
You are faster at something when it is congruent and reachable than incongruent and reachable but it is the same when it is congruent and incongruent and non-reachable
25 of 27
What is the role of the body in perceiving affordance?
A distinction can be made between perceived reach-ability and actual reach-ability . A common finding is that individuals exhibit a general tendency to perceive that they can reach objects that are out of reach
