  1. Infancy and Childhood • Developmental Psychology - study of changes that occur as individuals mature. • Beginning of Life • Reflexes • Grasping reflex - an infant’s clinging response to a touch on the palm of their hand. • Stepping reflex - infant’s held upright with feet touching the ground will attempt to walk. • Rooting reflex - infant’s response in turning toward the source of touching that occurs anywhere around the mouth. • Moro (startle) reflex - loud bangs or falling cause the infant to spread arms and legs. • Babinski(plantar) reflex - when a pointy object is run up the center of the foot.

  2. Infancy and Childhood • Intellectual Development • Developmental biologist - Jean Piaget • 4 stages of cognitive development: • Sensorimotor- birth to 2 years. Everything is based on senses (sensori-) and body movement (-motor). Thinking and action are directly connected. • 0-2 months - reflex stage • 2-4 months - primary circular reaction • 4-8 months - secondary circular reaction • 8-12 months - coordination of secondary reactions • 12-18 months - tertiary secondary reactions • 18-24 months - invention of new means through mental combinations

  3. Infancy and Childhood • Intellectual Development • Developmental biologist - Jean Piaget • 4 stages of cognitive development: • Sensorimotor- birth to 2 years. Everything is based on senses (sensori-) and body movement (-motor). Thinking and action are directly connected. • Preoperational - 2 to 7 years. Begin using mental images and symbols to understand. Language. Draw pictures. Can assign emotion to inanimate objects. Little moral sense (other than authority saying “don’t do that”) • 2-4 years - preconceptualstage • 4-6 years - intuitive stage

Language. Draw pictures. Can assign emotion to inanimate objects. Little moral sense (other than authority saying “don’t do that”) • Concrete Operational - 6-12 years. Organized, logical thought applied to concrete objects. Principle of conservation (the amount of an object remains the same though the shape changes). Concrete problem solving. Reversibility. Multiple classifications. Ability to view things from another person’s perspective. • Formal Operational - 12 to adulthood. Abstract problem solving. Algebra. Alternate solutions to complex problems. Can think of causes of an event without ever experiencing the event. Conservation
