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 intraoersonal and extrapersonal space? |
Intrapersonal: Body space and that within relatively near or reaching distance Extrapersonal: Space beyond 5 meters |
|
What disorders are related with intrapersonal and extrapersonal space? |
I: Distortions of body size, autotopagnosia, anosognosia E: Reduplicative paramnesia, topographical amnesia, and topographical agnosia |
|
What are Distortions of body size thought to be associated with? |
Temporal lobes Macrosomatognosia: Perception of enlarged body parts Microsomatognosia: Perception of smaller body size |
|
What is autotopagnosia? |
Impaired knowledge of body part locations (self and others) But can name, recognize, and describe functions of body parts |
|
What is gerstmann syndrome? |
Tetrad of symptoms associated with l angular g. dysfunction Finger agnosia, left right confusion of self and others |
|
What is anosognosia? |
Denial of unilateral neurological deficit |
|
What is reduplicative amnesia? |
Delusion of a replicated place May thought to exist in parallel worlds, or that it has been moved to another location Remains in the face of contrary evidence |
|
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.) |
|
What are the disorders of attention and consciousness? |
Blindsight, spatial neglect, and ballint Holmes syndrome |
|
What is blindsight? |
Lack of conscious awareness regarding visual perception |
|
What is spatial neglect? |
Refers to lack of awareness of one hemifield of space Fail to attend, report, or respond to info on neglected side |
|
What is ballint Holmes syndrome? |
Comprises of a set of visual spatial deficits due to bilateral lesion at the Parietal occiptal junction Optic ataxia, gaze apraxia, extreme narrowing of attention, impaired distance estimation |
