Unit 2 Modules 2.1a-2.2b Flashcards
The focusing of conscious awareness on a particular stimulus.
Selective attention
Ability to focus on one voice, while filtering out other distractions.

Failing to see visible objects when our attention is directed elsewhere.
Inattentional Blindness
Failing to notice changes in the environment.

Through experience, we come to expect certain results. Those expectations may give us a perceptual set also known as ____-_____ ____________
top-down processing
A predisposition to perceive things a certain way based on our expectations
Ex. We often tend to notice only certain aspects of an object or situation while ignoring other details
Perceptual set
Motivation, culture, expectation, emotion, stereotypes, and context all influence our _________.
perception
An organized whole
Looks at the human mind and behavior as a ______ rather than simply the sum of its parts
the whole may _______ the sum of its parts
gestalt
whole
exceed
is our mind filling in the gaps
Ex. Assuming the road you are driving on will continue even though it disappears over a hill
perceptual Inference
The Necker Cube is a good example of ___________ principle of _________.
Gestalt
closure
The way our mind distinguishes an object from the background
can be represented as a visual perception but can apply to non-visual fields as well (at crowded party you are focused on what your friends is saying rather than the conversations around you)
figure-ground relationship
Organizing stimuli into coherent groups
proximity
continuity
closure
similarity
grouping
How we see depth and judge distance
Depth perception
What are the 2 types of depth cues
Binocular cues (2 eyes)
Monocular cues (1 eye)
________ cues are better for judging depth of close objects
binocular
Retinal Disparity
Closer objects=larger ______ or noticeable difference
Your eyes compare two images to determine ________
disparity
distance
Muscular tension that occurs when the eyes turn inward to provide depth cues
Closer objects=more __________
Convergence
convergence
_______ cues are better for judging far off distances
monocular
Relative size/height=higher and smaller objects seem to be _____
further
Two parallel lines coming together in the distance
linear perspective
further objects appear more smooth with less texture
texture gradient
Items blocking other things appear closer
Interpositional cues
We see hazy, blurry and unclear as farther away
Relative clarity
When we are moving (in the car) stable objects seem to be moving
relative motion
Occurs when the brain perceives movement when varied images are viewed rapidly (flip book)
stroboscopic movement
Perceiving a series of still images in rapid succession as moving (Gestalt) illustrates stroboscopic movements
can also illustrate afterimage
Phi phenomenon
