How can we interact with space? |
By using position (body centered) , cued (guided by particular cues) , and place (environment based) responses |
|
|
What do species and individual differences indicate? |
Plasticity in spatial abilities and the hippocampus Eg. Taxi driver studies, food catching birds, hormone fluctuations in humans |

What Brain regions are implicated in the place, cued, and positional responses? |
Place: Hippocampus Cued and positional: Parietal, caudate, and frontal regions |
|
|

|
|
What is topographical amnesia? |
Refers to a deficit in navigating previously familiar environments Deficient cognitive mapping |
|
|
What is topographical agnosia? |
Deficit in associating landmark features with orienting value Claim that places are new to them, but they do recognize type of location (Building, etc.) |
|
