Define
dorsal simultagnosia
deficit in scene perception where the patient can only perceive ONE stimulus at a time (more severe than ventral type)
associative or amnesic type prosopagnosia
problems with recognizing familiar faces (they know it's a face, they just don't know who it belongs to)
are you racist
cancelled
blindsight
phenomenon where people who are perceptually blind demonstrate some response to visual stimuli
my back pain
all of the above
Akinetopsia
motion blindness; inability to perceive motion that arises from damage to the V5/MT (area of cortex responsible for visual motions)
apperceptive type prosopagnosia
problems with recognizing faces vs other objects (if presented with a a drawing of fruits that make a face, they can only recognize the fruits)
how many times are you breathing per minute
zero *bombs u*
associative visual agnosia
disorder in which visual object recognition is impaired but elementary visual perception is more or less preserved.
more common type
(they can't recognize name, categorize, or match the thing's function)
feliz
figment of imagination from ONE OF US
ventral simultagnosia
deficit in scene perception where patient can see multiple objects but cannot recognize them as a complete scene (can't put together the objects to say it's a kitchen for example)
central or cerebral achromatopia (2)
cortical color blindness; impairment of color vision in the entire visual field that arises from cortical lesions on the ventral surface of the temporal-occipital lobes.
(loss of color vision in the full visual field is rare and the lesions would need to affect color processing in both hemispheres)
hemiachromatopia and transient achromatopsia
do you think squids play basketball
what
visual object agnosia
disorder in which visual object recognition is impaired but elemntary visual perception is more or less preserved such as copying visually, drawing from objects from memory, and non-visual object recognition
Capgras syndrome
may arise from abnormal emotional response to faces which causes a disconnect between the temporal and limbic cortex
simultagnosia (2)
deficit in scene perception with normal visual fields and normal lower level visual perception
dorsal simultagnosia and ventral simultagnosia
hemiachromatopia (central or cerebral achromatopia)
loss of color vision restricted to one half of the visual field where the other has normal color vision
Capgras syndrome
ඞ, delusional belief that an acquaintance has been replaced by an identical looking imposter
apperceptive visual agnosia
disorder characterized by the inability to name, copy or recognize visually presented objects. shape perception and figure-ground segregation is impairs, but basic visual functions and object identification based on non-visual cues are preserved
(they can't name what it is visually but can if it's using their other senses such as smell)
Fregoli syndrome
damage to left frontal and right temporoparietal regions, possibly due to a disconnection between hemispheres that affects high-order face processing, objects, and events
transient achromatopsia (central or cerebral achromatopia)
temporary loss of color vision in any part of the visual field, usually from a TIA (transient ischemic attack)
prosopagnosia (2)
disorder in which faces cannot be recognized but other forms of object recognition are unimpaired
Fregoli syndrome
ඞ ; delusional belief that different people are the same person but they're just in different disguises (generally viewed with paranoia)
visual agnosia (2)
disorder in which the patient suffers from inability to recognize and identify objects, features of objects or scenes, faces or persons despite javing knowledge of the characteristics of aforementioned.
two types: apperceptive and associative
Akinetopsia
damage such as stroke, trauma and rarely from some antidepressants.
patients experience strobe-light effect of vision
