Type of fusion that is alignment of eye
Motor fusion
The brains ability to fuse the images
This fusion matters more
Sensory fusion
Spatial representation of body in its environment that allows us to navigate in our world for example walking through chairs in crowded rooms know where body parts are and how they move
Body schema
The internal awareness and integration of the two sides of the body
Laterality
Ability to project the internal awareness of the two sides of the body into extra personal space the spatial world of the ind
Directionality
Visualization ability to imagine sense become aware of manipulate and expand the pic in minds eye and feelings or senses in your body thereby dev new perspectives and creativity
Visual thinking
Reading writting math make a movie in head look for clues look at options
Visualization for learning
1/2 vision a condition resulting from malfunction or damage to one side of the optic tract common causes of hemianopsia are stroke trauma and tumor hemianopsias may vary from an absolute loss of all vision on one side ( light form and color) to a relative loss where vision is reduced but not completely missing. May vary from light or motion detection only in impaired field to subtle decreases in sensitivity only demonstrated on careful visual field testing location of damage or lesion along pathway determines the type of field loss
Hemianopsia
Vision is missing in the inner half of both the right and left visual fields
Bi-nasal hemianopsia
Vision is missing in outer half of both left and right visual fields
Bitemporal hemianopia
A loss of vision in the same visual field of both eyes
Homonymous hemianopsia
Hemi spatial agnosia visual spatial neglect or hemi-imperception caused by injury from stroke or other trauma it is a passive unconscious decreased awareness of part of the field of view or other stim to one side of body it usually occurs w a visual field defect but may also occur in the absense of field loss a person with a visual field loss would be aware of the area of loss and likely make compensations. A person with both visual field loss and visual neglect would unconsciously neglect the area of the field loss and be less likely to compensate for defect . Damage to right side of brain may cause both visual field loss and visual neglect to the left side right side brain injury normally more severe than left most common sight for visual neglect is parietal lobe but damage to frontal lobe and even deeper structures thalamus and basal ganglia may cause it
Neglect
Hemi spatial agnosia visual spatial neglect or hemi-imperception caused by injury from stroke or other trauma it is a passive unconscious decreased awareness of part of the field of view or other stim to one side of body it usually occurs w a visual field defect but may also occur in the absense of field loss a person with a visual field loss would be aware of the area of loss and likely make compensations. A person with both visual field loss and visual neglect would unconsciously neglect the area of the field loss and be less likely to compensate for defect . Damage to right side of brain may cause both visual field loss and visual neglect to the left side right side brain injury normally more severe than left most common sight for visual neglect is parietal lobe but damage to frontal lobe and even deeper structures thalamus and basal ganglia may cause it
Neglect
Special filters which allow full transmission of light in one direction gradually reducing the amt of transmission to zero at a point 90 degrees away by using a pair of Polaroid glasses w 2 filters oriented in opposite directions from each other and a special set of Polaroid targets we control the info that is available to each eye designed to provide stereoscopic 3d effect 2 images slightly offset
