,bottom-up processing Takes the basic sensory components of an object and adds them to identity
what it is
top-down processing information processing guided by higher-level mental processes, as when we
construct perceptions drawing on our experience, expectations, and memories
Akinetopsia Disorder in which patient is unable to see objects in motion - as if they're
lagging in time.
what patient had akinetopsia? LM-could not tell when cars were moving or parked. Could not tell when
coffee cup was full
Cornea the transparent layer forming the front of the eye.
-involved in focusing light waves that enter the eye.
puplil small opening in the eye through which light passes
-pupils dilate (expand) in low light
Iris the colored part of the eye, there are muscles that control the size of the pupil
, Lens curved Structure in the eye that focuses light rays on the retina, along with the
cornea. Changes shape to aid in focusing light that is reflected near or far
objects
Surrounded by a band of muscle. When muscle tightens, lens buldges (nearby
objects). When muscle relaxes, lens flattens (far objects).
Fovea lens focuses images perfectly on this small indention in back of the eye
Retina Light sensitive tissue that lines the back of the eyeball
Photoreceptors Specialized neural cells that respond directly to incoming light. 2 types: rods
and cones
Rods -basic shapes/forms
Photoreceptors that are sensitive to low levels of light and play an essential
role for moving in semidarkness. Can distinguish between intensities of light,
but not colour. None in fovea, mostly periphery
