PSYC 230 Exam 3 REVIEW UPDATED
ACTUAL Questions and CORRECT
Answers
object perception - CORRECT ANSWER -Allows us to identify things out in the world
and make sense of it
object agnosia - CORRECT ANSWER -Cannot label objects to identify them
EX: red roses Someone with this can detect visual features (say it is red circles), but cannot
actually put everything together and say it is red roses
EX: two pictures of remotes one straight on, one turned to the side
*But can still recognize both pictures as a remote control
If shown a complex/unknown object, hard to answer simple questions on the object... -
CORRECT ANSWER -What is it? How big? What does it do?
But once you know it is a flower, you have PRIOR KNOWLEDGE ABT FLOWERS WE CAN
BRING IN TO MAKE SENSE OF THIS
bottom up processing - CORRECT ANSWER -Process whereby physical stimuli influence
how we perceive them
Light hits eyes, goes into ganglion cells and visual cortex, so on
REFER TO THE SIGNALS THAT COME FROM THE STIMULI IN THE WORLD AND GO
UP THE VISUAL SYSTEM TO HIGHER LEVELS OF INTERPRETATION
PERCEPTION THAT ARISE DIRECTLY FROM PHYSICAL PROERTIES
, top down processing - CORRECT ANSWER -A process whereby our existing knowledge
of objects influences how we perceive them
EX: pull out car, understand that it is a car from prior knowledge, prior knowledge makes it
easier to understand that it is a car even if hand is blocking part of it
recognition - CORRECT ANSWER -Ability to match a presented item with an item in
memory (already there in memory)
EX: pets --> go beyond recognizing that's a dog, recognize that's MY DOG or that's my
FRIENDS DOG (name and emotion associated with the pet)
representation - CORRECT ANSWER -The storage and/or reconstruction of information
in memory
Way the brain can have a concept of something
EX: know the sun is hot and bright
Accepting the idea that we have memories and that these memories are concepts of our world
top-down processing is
A. A process whereby physical stimuli influence how we perceive them
B. A process whereby our existing knowledge of objects influences how we perceive them
C. A process in which the top if objects is more salient than the bottom of objects
D. Processing that occurs first in the higher cortical areas and then is sent directly to the sensory
organs - CORRECT ANSWER -B -- EXISTING KNOWLEDGE
perceptual organization 2 parts - CORRECT ANSWER -1. grouping
2. Segregation
