Chapter 7 Perception
Sensation vs. Perception
Sensation refers to raw energy, bottom up input
AB12 13 14 example tells perception kicks in with the context around the objects
Brain Regions and Visual Perception
Primary visual cortex is made up of a large number of “modules
which contain a large number of nerve cells that all respond to
different aspects of the same part of the retina … termed the
visual field of those nerve cells
The retina is not evenly represented but, instead, more primary
cortex is devoted to images at or near the fovea
Some nerve cells in a module respond only to lines of certain
orientations, others respond only to motion, others to colour, etc
Thus, primary cortex codes the basic features of the image it
receives

Secondary visual cortex regions (i.e., association cortex) is
responsible for higher level visual processes as revealed by
various types of brain injury:
Damage to primary visual cortex - often results in “blind spots
but no problems with object recognition
Damage to one part of association cortex can lead to an inability
to see colour altogether, a problem termed achromatopsia
Damage to a slightly different part of visual association cortex
can result in an inability to perceive motion
Visual Agnosia and Prosopagnosia
Visual agnosia – when person cannot tell the function of an object
Prosopagnosia – inability to recognize faces, even those of very familiar people
Basic Issues - Figure vs. Ground

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
