Chapter 4 Flashcards
States of Arousal
Degrees if sleep or wakefulness
Reflex
Is an inborn, automatic response to a particular form the of stimulation
Rapid eye movement sleep
Brainwave activity, measured with EEG is remarkably similar to that of the waking state. The eyes dart beneath the lids, heart rate, blood pressure, and breathing are uneven, slight body movements occur
Non-rapid-eye movement
The body is almost motionless, and heart rate, breathing, and brain wave activity are slow and even
Sudden infant death syndrome (SIDS)
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, responsive to physical and social stimuli,and other reactions
Habituation
Refers to a gradual reduction in the strength of a response due to repetitive stimulation
Recovery
A new stimulus- change in the environment–causes the habituated response to return to a high level
Imitation
By copying the behavior of another person
Mirror neurons
In the cerebral cortex, that underlie these capacities. Mirror neurons fire identically when a private hears or sees an action and when it carries out that action on its own.
Dynamic systems theory of motor development
Mastery of motor skills involves acquiring increasingly complex systems of action. When motor skills work as a system, separate abilities Belen together, each cooperating with others to produce more effective ways of exploring and controlling the environment
Prereaching
Newborns making poorly coordinated swipes
Ulnar grasp
A clumsy motion in which the babies fingers close against the palm
Pincer grasp
Infants use the well coordinated thumb and index finger
Statistical learnings capacity
By analyzing the speech stream for patterns–repeatedly 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 age 12 months
