Document Summary
Chapter five: physical development in infancy and toddlerhood. Affection is as vital as food for healthy physical growth. Weight, height, and head circumference are substantially below age-related growth norms. Unhappy marriage and parental psychological disturbance are often involved. Newborns have primitive ability to learn by copying another person"s behavior. Neural mirroring systems may underlie early imitative capacities. View of newborn imitation as a flexible, voluntary capacity remains controversial. Capacity to imitate expands greatly over first two years. Each new skill is a joint product of four factors: central nervous system development. Home environment and infant rearing practices affect motor development. Some cultures discourage rapid motor progress; others actively encourage it. Western practice of having babies sleep on their backs to protect them from sids delays motor milestones. 6-8 months: screen out sounds from nonnative language. 7-9 months: divide the speech stream into word-like units. 10 months: detect words that start with weak syllables.
