perception vocab and practice
Perspective and texture gradients are examples of
monocular cues
retinal disparity
A binocular cue for perceiving depth based on the different locations of the two images on the right and left retina.
reversible figure
A drawing or picture that has two different interpretations often seen by adjusting visual perception.
stroboscopic motion
A visual illusion in which the perception of motion is generated by the presentation of a series of stationary images in rapid succession.
Retinal disparity is an example of a(n)
BINOCULAR CUES
List and explain two rules for perceptual organization.
Closure is the perception of a complete or whole figure when there are gaps in what the senses tell you. Figure-ground perception is how what we perceive as the background and the figure will influence our perception. Proximity is when we perceive things as being in pairs just because they are close to each other. Similarity is when people perceive similar objects as being together. Continuity is when people prefer to see smooth patterns. Common fate is when we perceive people who are walking in the same direction to be heading to the same place.
monocular cues
Cues for distance that may be available to either eye alone.
Explain the difference between bottom-up and top-down processing.
Responses may vary but should include some or all of the following information: Bottom-up processing is a process in feature analysis that occurs when individuals detect specific elements or features of a stimulus, combine the features into more complex forms, and then recognize the stimulus as a whole. Top-down processing occurs when individuals determine or recognize the stimulus as a whole, examine or analyze the features, and then recognize the individual elements.
continuity
The perceptual tendency to group stimuli into continuous patterns.
similarity
The perceptual tendency to group together elements that seem alike.
proximity
The perceptual tendency to group together visual and auditory events that are near each other.
closure
The tendency to perceive a complete or whole figure even when there are gaps in sensory information.
common fate
The tendency to perceive objects that are moving together as belonging together.
binocular cues
Visual cues for depth that require the use of both eyes.
According to perception of movement, in order to sense movement, humans need to see an object _____. a. change its position relative to other objects b. change its position, regardless of what's around it c. change its position relative only to other moving objects d. change its position while something else moves in the same way
a
According to the rule of continuity, people would prefer to see _____. a. continuing lines rather than shapes c. lines with many angles b. shapes rather than just lines d. random segments of lines Please select the best answer from the choices provided A B C D
a
Visual illusions occur when perceptual cues are distorted and our brains cannot correctly interpret ___ cues. a. size, shape, and color. c. texture, light, and depth. b. size, space, and depth. d. proximity, brightness, and color.
b
The convergence of two things as a result of retinal disparity is an example of which of the following? a. shape constancy c. a binocular cue b. brightness constancy d. stroboscopic motion
c
Perceptual preference for seeing smooth, continuous patterns
continuity
Which of the following is the term used to describe a process that occurs when still pictures are projected in rapid succession, creating the illusion of movement? A. feature analysis B. inattentional blindness C. retinal disparity D. phi phenomenon
d
An individual needs only one eye to function in order to interpret a binocular depth cue.
f
When we perceive a solid shape, even when the shape is broken, we are applying the rule of proximity.
f
We recognize that an object has only one shape—no matter what angle it is viewed from—because of
shape constancy
Movies, which are a series of still pictures, are perceived as moving images because of ________. shape constancy stroboscopic motion relative size retinal disparity
stroboscopic motion
Perception is the way we organize or make sense of our sensory impressions.
t
Perceptual constancies are created through experience.
