The visual cliff is a test given to infants to see
if they have developed depth perception
. … If it stops when it gets to the edge of the platform, looks down, and either is reluctant to cross or refuses to cross, then the child has depth perception.
What did the visual cliff experiment determine about infants quizlet?
What did the visual cliff experiment determine about infants?
They can perceive depth by the time they are old enough to crawl.
What did the visual cliff experiment demonstrate?
We use the angle of our eyes for depth while a blind person determines depth with the angle of the stick in his hands. Visual cliff experiments in humans show that
human infants: avoid the deep side from ~1 month after learning to crawl
. … When babies are first learning to crawl, they don't seem to notice the cliff.
What were the findings of the visual cliff experiment quizlet?
By the time infants were tested on the visual cliff, they
had been crawling for enough time that they had learned to avoid such situations
. Because of this critique a later study placed babies aged from 2 to 5 months and the study showed a decrease in heart rate, showing a sign of interest not fear.
Which visual process is the visual cliff designed to measure or assess?
Visual Cliff test is a simple and inexpensive apparatus to test
visual acuity and depth perception
. The apparatus can be easily adapted for other animals. Visual Cliff test utilizes the fear of heights using the illusion of a cliff drop.
Which animal was most afraid of the visual cliff?
Before Gibson and Walk conducted their study with human infants, multiple experiments were conducted using
rats
, one-day-old chicks, newborn kids, kittens, pigs, adult chickens, dogs, lambs, and monkeys. Overall, most species would avoid the deep side of the visual cliff, some right after being born.
What does the visual cliff experiment tell us about depth perception?
As the infants were able to detect the danger from the ‘cliff' side, Gibson and Walk concluded that their
depth perception might be innate
– it was at least present as soon as they could crawl. … Together, the findings suggest that depth perception is an innate process.
What is the importance of the visual cliff experiment?
In 1960, researchers conducted a “visual cliff” experiment and concluded that depth perception is innate, and
it keeps babies safe from dangerous, height-related obstacles
.
Why do infants crawl over the edge of a real or a visual cliff How do you know?
Visual Cliff Infant Test
Gibson and walk concluded that
the ability to perceive depth emerges sometime around the age that an infant begins to crawl
. The fear of heights, they suggested, is something learned later in infancy as gain experience with bumps, scrapes, and falls.
What infant response did Gibson and Walk 1960 measure in the visual cliff research quizlet?
-found that 2-day-old infants look longer at patterned stimuli than at single-colored discs. -Gibson and Walk conducted the classic “visual cliff” experiment in 1960 to
assess how early infants could perceive depth
. -They placed a piece of glass over a drop-off patterned the same as the table next to it.
What is the visual cliff and what does it teach us quizlet?
A visual cliff is
created by connecting a transparent glass surface to an opaque patterned surface
. The floor below has the same pattern as the opaque surface. This apparatus creates the visual illusion of a cliff, while protecting the subject from injury.
When two objects cast a retinal image of the same size the one that is perceived as being?
Relative Size
: If we assume two objects are about the same size, the one that casts the smaller retinal image is perceived as being farther away.
Which two principles describe the order in which a child develops motor skills?
Gross motor skills development is governed by two principles that also control physical growth. Head to toe development refers to the way the upper parts of the body develop, beginning with the head, before the lower ones. The second principle of development is
trunk to extremities
.
Is the visual cliff experiment nature or nurture?
Lesson Summary
nurture
debate. One famous experiment done on nature vs. nurture in development is the Visual Cliff Experiment, which looked at whether infants only a few months old have depth perception or not.
Do animals experience depth perception?
Depth sensation is the corresponding term for animals, since although it is known that animals can sense the distance of an object (because of the ability to move accurately, or to respond consistently, according to that distance),
it is not known whether they perceive it
in the same subjective way that humans do.
