Quiz 4: Sensory/Perceptual Develpment Flashcards
All of the following descriptions of newborn infants’ sensory and perceptual abilities are correct except
they perceive the full range of colors that older children/adults perceive
(Because of limitation in acuity and contrast sensitivity, infants have a limited range of color perception)
The smallest spacing that can be perceived between parts of a pattern is known as…
visual acuity
Recent studies of infants’ perception of objects suggest that they are able to use all of the following sources of information except…
still photos of objects taken from a single perspective
(Many scholars believe that the visual system evolved to favor dynamic information (movement) over stationary or static information (pgs. 168-69)
In one ingenious study of ___ perception, researchers first gave 1-month old infants a bumpy pacifier to feel in their mouth and only later allowed them to look at that pacifier - after they had placed it next to a smooth pacifier that they had not explored orally.
cross-modal
(cross-modal perception is when we take information from one sense (e.g. touch) and can then transfer that information to another sense, such as vision.
The first depth cue that infants use is called ___
kinematic
(The earliest depth cues are often carried by kinematic info., which often involves movement. This can also include elements of optical expansion and contraction as described on p. 169 and table 6.3)
Auditiory localization, the ability to detect the direction a sound is coming from…
appears to undergo a U-shaped developmental change from birth to about 6 months of age.
Hannah, a newborn infant, is coming home from the hospital for the first time. Her parents want her nursery to provide optimal visual stimulation. Research would support including all of the following features except…
pastel colors, especially light yellow and green.
(Because of limited contrast sensitivity and a lack of cones sensitive to certain wavelengths in the light spectrum, newborns may have a more difficult time distinguishing between light colors (p. 165).
According to the ___ theoretical view, the visual system perceives meaningful information directly, without any intermediate steps to interpret it.
ecological
(This view was advanced by scholars such as Jack Gibson and is built on the idea that the visual system receives direct info. from the environment without intermediary steps.
If infants took longer at a video display that shows another infant’s legs moving than at a video display that shows their own legs moving, researchers studying inter modal perception have concluded that…
infants younger than 8 months are sensitive to the absence of a contingency between the feeling of their own legs’ movements and the image of the other infant’s legs moving.
Which of the following would be the best way to test infants’ ability to perceive amodal properties of events?
displaying two different visual images that are accompanied by a soundtrack matching one of the images.
