information that can be presented to different senses, such as duration, rate, and intensity
processes that determine which information will be processed further by an individual
the quietest sound that a person can hear
specialized neurons in the back of the eye that detect wavelength of light and, therefore, color.
distinguishing and mastering individual motions
dynamic systems theory
a theory that views development as involving many distinct skills that are organized and reorganized over time to meet demands of specific tasks.
motor skills associated with grasping, holding, and manipulating objects
becoming unresponsive to a stimulus that is presented repeatedly
linking individual motions into a coherent, coordinated whole
a perceptual cue to depth based on the fact that nearby objects partially obscure more distant objects.
intersensory redundancy theory
a view, proposed by Bahrick and Lickliter, that the infant's perceptual system is particularly attuned to amodal information that is presented to multiple sensory modes.
depth cues based on motion, such as visual expansion and motion parallax
a cue to depth perception based on the fact that parallel lines come together at a single point in the distance
the ability to move around in the world
a kinetic depth cue in which nearby moving objects move across a person's visual field faster than distant objects.
coordinated movements of the muscles and limbs.
the response to an unfamiliar or unusual stimulus in which a person startles, fixates the eyes on the stimulus, and shows changes in heart rate and brain-wave patterns.
depth cues like those used by artists to convey depth in drawings and paintings; examples include linear perspective and interposition
a perceptual cue to depth based on the fact that nearby objects look substantially larger than objects in the distance.
a perceptual cue to depth based on the fact that, when a person views an object, the retinal images in the left and right eyes differ.
sensory and perceptual processes
the means by which the nervous system receives, selects, modifies, and organizes stimulation from the world.
the realization that an object's actual size remains the same despite changes in the size of its retinal image.
a perceptual cue to depth based on the fact that the texture of objects changes from coarse but distinct for nearby objects to finer and less distinct for distant objects.
young children who have just learned to walk
the smallest pattern that one can distinguish reliably
a glass-covered platform that appears to have a "shallow" side and "deep" side; used to study infants' depth perception.
a kinetic depth cue in which approaching objects fill an ever-greater proportion of the retina
