rapid-eye movement sleep
electrical brainwave activity, measured with the EEG, is remarkably similar to that of the waking state.
Non-rapid movement sleep
the body is almost motionless, and heart rate, breathing, and brain-wave activity are slow and regular.
Sudden Infant Death syndrome
the unexpected death, usually during the night, of an infant younger than 1 year of age that remains unexplained after thorough investigation.
Neonatal Behavioral Assessment Scale
evaluates the baby's reflexes, muscle tone, state changes, responsiveness to physical and social stimuli, and other reactions
possible in the young infant. in this form of learning, a neutral stimulus is paired with a stimulus that leads to a reflexive response. Once the baby's nervous system make the connection between the two stimuli, the new stimulus will produce the behavioral itself.
infants act on the environment, and stimuli that follow their behavior change the probability that the behavior will occur again.
removing a desirable stimulus or presenting an unpleasant one to decrease the occurrence or a response.
refers to a gradual reduction in the strength of a response due to repetitive stimulation
a new stimulus- a change in the environment-causes the habituated response to return to a high level.
Fire identically when a primate hears or sees an action and when it carries out that action on its own.
head to tail sequence, is evident: Motor control of the head comes before control of the arms and trunk, which comes before control of the legs.
Meaning from the center of the body outward: Head, trunk, and arm control precedes coordination of the hands and fingers.
Dynamic Systems of Motor Development
mastery of motor skills involves acquiring increasingly complex systems of action. when motor skills works a system, separate abilities blend together, each cooperating with other to produce more effective ways of exploring and controlling the environment.
Statistical learning capacity
Analyzing the speech stream for patterns-regularly occurring sequences of sounds-they acquire a stock of speech structures for which they will later learn meanings, long before they start to talk around are 12 months.
Designed by Eleanor Gibson and Richard Walk and used in the earliest studies of depth perception. It consists of Plexiglas-covered table with a platform at the center, a shallow side with a checkerboard pattern just under the glass, and a deep side with a checkerboard several ft below the glass.
Explains early pattern preferences. If babies are sensitive to the contrast in two or more patterns they prefer the one with more contrast.
Perception of an object's size as stable, despite changes in the size of its retinal image
Perception of an object's shape as stable, despite changes int eh shape projected on the retina
We make sense of these running streams of light, sound, tactile, odor, and taste information by perceiving them as integrated wholes.
Amodal Sensory properties
information that is not specific to a single modality but that overlaps two or more sensory systems, such as rate, rhythm, duration, intensity, temporal synchrony, and texture and shape.
Infants actively search for invariant features of the environment- those that remain stable- in a constantly changing perceptual world.
