Psych 210: chapter 3 midterm 2 notes
3.1:
Helmholtz: recognized that perception requires unconscious inferencing which actively
constructs an interpretation
Vision that come from the retina is two dimensional and can have countless interpretations for
3d images
o Unspecified information: vision that comes from the retina and some something the
brain has to cope with ****
o Poverty of stimulus: the eye does’t take i eough light fro the ojet to for a 3d
image
Brain uses unconscious knowledge is domain specific to the visual cortex
Generic view: we assume that the image we are seeing is the generic view (what
the object usually looks like)
Accidental view: the view of an object that appears different from all other
views
o Y-junction and arrow junctions: are where two flat surfaces meet, so the visual system
can identify that an object has corners
The Helmholtz sign theory: an object does not have to be physically seen but can be inferred by
the visual system*******
o Contrast can be inferred by the visual system (ie: dark circle with light background will
appear different then the same dark circle with a darker background)
Both language and vision require unconscious inferencing
o Sign theory: there id no simple resemblance between the neural events that give rise to
sensations and physical objects. The corresondance is symbolic and created within the
mind
Descartes and Helmholtz had a similar view points when analyzing the
relationship between neural events and the physical world.
Helmholtz argued however that our visual constructions from neural
signals is learned and that nothing is innate
3.2
A human reaction cannot happen any faster than 110ms the brain needs time to process and
make descions
Chronometry: influenced by Wundt, it is a method for timing the reaction speed of the brain
FC Donders: worked with Wundt and proposed the Subtractive method
o Subtractive method: the idea to designate a number to each mental task for some
activity that will overall add together to produce the overall reaction time. Stages can
therefore be isolated by subtracting one specific tasks reaction time from another (This
theory is INCORRECT)
o A simple reaction to donders would be a sprinter starting to run at the sound of a gun
(responding to only one stimuli)
The tasks according to Donders were split us as follows
o Task A: Response execution
o Task B: a Choice reaction ( ie: identifying a shape) which involves stimulus identification
and response selection

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!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
