The functions of Vision Flashcards
What’s needed to enable recognition
Internal representation
In terms of visual pathways, where does light go after it passes the retina
To the primary visual cortex
In terms of visual pathways where does light go after passing the primary visual cortex
The parietal cortex and then the temporal cortex
Define Optic Ataxia
A condition in which there are problems with making visually guided movements in spite of reasonably intact visual perception.
What is the Ventral stream
The party of the visual processing system involved in object perception and recognition and the formation of perceptual representations.
What is the dorsal stream
The part of the visual processing system most involved in visually guided action
What is allocentric coding
Visual coding that is independent of the observers perspective
What is egocentric coding
Visual coding that is dependent on the observer’s perspective
What is visual form agnosia
A condition in which there are severe problems in shape perception but has a reasonable ability to produce accurate visually guided actions
Where does someone have damage to have visual agnosia
Damage to the occipital-temporal cortex
What is Optic ataxia
A condition in which there are problems with making visually guided movements in spite of reasonably intact perception
Where does one have to have damage to have optic ataxia
Damage of the posterior parietal cortex
