The Amazing Development of the Brain Brain develops rapidly before and after birth. Cerebrum's role: language, perception, and intelligence. Just before birth: newborns have most brain cells. Rapid development of neural connections.
Motor Development Movements governed by reflexes. Reflexes: automatic, built-in responses to stimuli. Examples: coughing, blinking, yawning. Reflexes are survival mechanisms and foundations for motor development.
Reflexes and Voluntary Control Reflexes disappear as brain matures. Voluntary control over behavior develops. Examples: - Coughing: reflex persists throughout life. - Rooting reflex: disappears as baby gains voluntary control over head movements.
Physical (Motor) Development Muscles and nervous system mature with growth. Development of finer skills. Basic motor skills: grasping, reaching, sitting, crawling, walking, running. Sequence of development is universal.
Sensory Abilities Newborns recognize mother's voice hours after birth. Preferences for stimuli (e.g., faces). Vision: lower than adults, improves by 6 months, 20/20 by first year. Color vision: distinguish red and white, full color vision by 3 months. Hearing, touch, smell, and taste present at birth.
Cognitive Development Jean Piaget: children actively construct understanding of the world. Series of stages from infancy to adolescence. Each stage characterized by distinct thinking, age-related. Infancy: experiencing the world through senses and interactions. Lack of object permanence (awareness that objects continue to exist when not perceived).
Object Permanence Example: hiding a toy. Young infants don't search for hidden toys. By 8 months: start pursuing partially covered objects. Basis of verbal communication in infants: babbling (3-6 months).
Socio-Emotional Development Babies are social creatures from birth. Prefer familiar faces, respond to parents. By 6-8 months: show preference for mother. Cry or show distress when separated from mother, reciprocate with smiles or hugs upon reunion.
Attachment Close emotional bond between infants and parents/caregivers. Harlow and Harlow's study: baby monkeys preferred cloth mother over wire mother. Contact-comfort important for attachment.
Erik Erikson's Theory First year of life: key for developing trust or mistrust. Trust: built on physical comfort and responsive, sensitive parenting. Secure attachment: positive response when picked up, move freely, and play. Insecure attachment: anxious when separated, cry, and get upset.
Summary Brain development before and after birth. Newborn abilities and reflexes. Physical, sensory, cognitive, and socio-emotional development. Importance of attachment and trust in early years.
