Development In Infancy • Newborn infants recognize voices, (audition) faces (vision), taste and smell, and learn (imitation).
Development In Infancy • Infants are classically (Pavlov) and operantly conditioned (Skinner) • positive reinforcers, such as mother's voice (non-nutritive sucking)
Development In Infancy • biological development according to genes = maturation. • physical development right after birth is highest
Development In Infancy • precocious babies develop physical or cognitive abilities early; others slower to develop, but usually all catch up.
Newborn (neonate) Reflexes • Rooting Sucking • Moro Startle • Palmar/grasp Babinski • Tonic neckStepping • Crawling/swimming • Blinking, breathing, crying, yawning
Cortical behaviors • Head at 45* angle • Roll over • Sit up • Walk with help • Crawl • Walk without help
Cognitive Development In Childhood • Jean Piaget – cog. dev. relies on formation of schemas: • organized mental representations of the world
Cognitive Development In Childhood • Assimilation – adding new material or info to existing schema (folders) • Accommodation – changing existing schema to accommodate new experience
Cognitive Development In Childhood • Jean Piaget -- cognitive development progresses through a series of 4 overlapping qualitative stages: sensorimotor, preoperational, concrete operational and formal operational.
Sensorimotor stage (0-2 yrs) • During sensorimotor stage, infants and young children learn through their senses and acquire principle of object permanence, the recognition that objects still exist when not visible.
Sensorimotor stage (0-2 yrs) • Language ineffective • Learn by sensing (sensori) and doing (motor) • Learn causality – if A then B • Imitation (peek-a-boo, dancing)
Preoperational stage (2-6/7 yrs) During preoperational stage, child can use symbolic representations for objects and events not physically present. • This stage also characterized by egocentrism, the inability to see situations from another person's point of view. (me, mine)
Concrete operational (6-12 yrs) • Children continue to use mental representations and can think logically, but are not yet able to think abstractly during the concrete operational stage.
Concrete operational (6-12 yrs) • Concrete objects can be classified, ranked, ordered or separated into more than one category according to rules. • Can get to school but can’t abstractly draw or describe the route.
Principle of Conservation • recognition that changes in size or shape do not change the amount of a substance-is acquired during this stage.
Formal operational (12 yrs+) • Children can think abstractly and hypothetically during the formal operational stage. • Independent morals develop
