PSYC 2301 Exam 2 Latest Questions And Answers
With Real Quizzes
difference between sensation and perception ANS Sensation concerns the collection of sensory while
perception concerns the organization and interpretation of this sensory information
transduction ANS The process which external stimuli is translated into something that our sensory
neurons understand
Smell sensory cells ANS Olfactory Receptors
Auditory sensory cells ANS Hair Cells
Taste sensory cells ANS Taste Buds
What five characteristics are coded by our taste buds? ANS Sour, Sweet, Salty, Bitter and umami (i.e.
savory)
Why do we have a blind spot in each eye and Why don't we notice it? ANS There is no retina thus no
photoreceptors at the optic disk in each eye, we don't notice it because of the lack of photoreceptors
What explains red-green color blindness ANS Individuals with this only have 2 cones, they have blue
cones but lack either red or green cones.
difference between bottom-up vs. top-down processing ANS Bottom-up gives meaning to our stimuli
by basing it mostly on the "pure sensory" experience of it while top-down is our stimuli based on past
experiences and knowledge
When things are ambiguous, what kind of processing do we rely on? ANS We rely on bottom-up
processing
, figure-ground principle ANS When we tend to break up our visual world into figures and the
background they rest upon
difference between the absolute threshold and the difference threshold ANS The absolute is a measure
of how far we can push our sensory detection capabilities while the difference threshold is the smallest
possible difference between two stimuli that can be detected
How do "after images" help explain color processing? ANS when you first look at a static image you
eventually adapt to the color that is being activated, eventually the activated color turns off and its
opponent turns on
Trichromatic Theory ANS The combined activation of Red, Green and Blue leads to perception of
different colors
opponent-process theory ANS the theory that opposing retinal processes (red-green, yellow-blue,
white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red;
others are stimulated by red and inhibited by green
What are the 4 gestalt guidelines of perception discussed in class ANS Law of Closure, Law of
Similarity, Law of Proximity and Law of Good Continuation
What are the 6 monocular cues used to process depth ANS Relative size, Overlap, Texture gradient,
Aerial perspective, Linear perspective and Motion parallax
the 2 binocular cues used to process depth ANS Convergence and Binocular Disparity
What is shape and size constancy ANS Size Constancy: Just because closer objects look bigger that
does not mean they are bigger.
Shape Constancy: Just because the retina image changes this does not mean the shape of the object
changes
Define attention and understand the limits of attention ANS the ability to selectively focus awareness;
we can't pay attention to everything
