This explains why these words in white letters
stand out from the blue
3
What is the figure-ground principle?
4
This principle explains how we organize elements
into basic shapes. That was easy!
5
What is simplicity?
6
Dont stand so close to me, we might be grouped
together based upon this principle
7
What is proximity?
8
I couldnt seem to fill in what was missing, but
now its done Im glad I found this
9
What is closure?
10
When you see a fork in the road, take it. Oh
well, well probably stay on the same path,
despite interruptions, thanks to this principle
11
What is continuity?
12
Can you hear me now? If so, I must have passed
this level of stimulus intensity
13
What is the absolute threshold?
14
Theres only one p in pool, but Id watch out
for those warm spots by those kids. If you
sensed that the temperature has changed youve
reached this
15
What is a just noticeable difference?
16
Can you read the words after the colon Mr. Klein
is great!If you cant detect itcorrectly 50 of
the time, it counts as this
17
What is a subliminal stimulus?
18
This states that the magnitude of a sensory
experience is proportional to the number of JNDs
that the stimulus causing the experience is above
absolute threshold. There should be a law
against such long definitions.
19
What is Fechners law?
20
With so much noise in here, Im going to have a
lot of false alarms according to this theory
21
What is signal detection theory?
22
Who needs night vision goggles? Ill just look
slightly above or below the object in order to
stimulate these cells
23
What are rods?
24
Oh no, my lens is focusing the image too short to
reach the retina! I have this condition
25
What is nearsightedness?
26
I really need to read the fine details and
analyze the colors. Im going to make sure I use
this section of the retina that exclusively
contains cones
27
What is the fovea?
28
Love is blind, and so are we all at the blind
spot. Its located at this spot where the optic
nerve connects to the retina
29
What is the optic disc?
30
This is the point at which the optic nerves from
the inside half of each eye cross over and then
project to the opposite half of the brain (dont
jump off a cliff if you cant pronounce it)
31
What is the optic chiasm?
32
According to this theory, combining three primary
colors can yield a million different colorful
perceptions. A likely story.
33
What is trichromatic theory?
34
Stop being such a baby. Dont do the opposite of
what the cells next to you in the retina are
doing. Oh well, I guess its hard to avoid this
pattern of neural activity
35
What is lateral antagonism?
36
About 90 of the axons from the retinas synapse
here must be some nice nucleus see if you can
make a Lucky Guess
37
What is the lateral geniculate nucleus?
38
These two channels of the main visual pathway
engage in parallel processing they are
magnificent in their ability to parse through
complex images we all encounter
39
What are the magnocellular and parvocellular
channels?
40
Trying to see that bug on the tip of your nose is
making you cross-eyed. Your eyes are using too
much of this binocular depth cue
41
What is convergence?
42
Whoa! We must be going really fast, those
lampposts are a blur thanks to this monocular
depth cue
43
What is motion parallax?
44
I dont care if your uncle looks taller than
mine, its just because my uncle is farther away.
Besides thats not where this pictorial depth
cue gets its name
45
What is relative size?
46
I dont want to start an argument, but my left
eye is seeing a different image than my right.
Good thing my brain is using this information to
calculate depth
47
What is retinal disparity?
48
Wow! Look at the detail in this flower close to
me. I wish I could see as much detail in that
pretty yellow one in the distance. It must be
the work of this pictorial cue
49
What is texture gradient?
50
Our experience with room corners can help explain
this illusion found on many a cereal box
51
What is the Müller-Lyer illusion?
