Integrating Perception and Movement
finish this quote by Robert Kiyosaki
“sight is what you see with your eyes, vision ……….
“sight is what you see with your eyes, vision is what you see with your mind”
around half of the cerebral cortex is devoted to what
visual processing
if optical information is ambiguous what will humans do
humans rewight other sensory inputs
where are the cones concentrated in for our vision
concentrated in central retina
where are rods found for vision
peripheral retina
what are rods very sensitive to
light
where is the retina found in the eye
lining of the back of the eyeball
what is the primary sensory organ of the visual system
the retina
what is transduction (visual system)
light waves are converted to electrical impulses
when are cone cells more stimulated
high levels of day vision
when are rod cells more sensitive
more sensitive to low levels of resolution (movement in dark)
what are the 6 extraocular muscles
- superior rectus muscle
- inferior rectus muscle
- medial rectus muscle
- lateral rectus muscle
- superior oblique muscle
- inferior oblique muscle
5 types of eye movements
- vestibular-ocular reflex
- optokinetic reflex (responsible for large movements around)
- smooth pursuit
- saccades
- vergence
what are the skilled eye movements that need to be practiced
- smooth pursuit
- saccades
- vergence
what is monocular vision
seeing with only one eye at a time
