1. Developmental Psychology Infancy and Childhood

2. So what will a healthy newborn do? Reflexes Rooting Reflex- a babies tendency, when touched on the cheek, to open mouth and search for a nipple. Turn towards human voices. Gaze longer at human face like images.

3. How do brain and motor skills develop? Good News While in the womb, you produce almost ¼ million brain cells per minute. Bad News That is basically all you are ever going to develop.

4. The Brain and Infancy Although the brain does not develop many new cells, the existing cells begin to work more efficiently- forming more complex neural networks.

5. Maturation Biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience. To a certain extent we all maturate similarly, but the time can vary depending on the person.

6. Motor Development Sequence is the same- but once again timing varies. First learn to roll over, sit up unsupported, crawl, walk etc…

7. Walking Walking- in US 25% learn by 11 months, 50% within a week of 1 st birthday, 90% by 15 months. Varies by culture- if the culture emphasizes walking then babies can walk at younger ages (NURTURE). But identical twins tend to learn to walk on the same day (NATURE).

8. Toilet Training NO MATTER WHAT, THE BABY NEEDS THE PHYSICAL MATURATION TO HOLD HIS OR HER BLADDER OR BOWEL MOVEMENTS BEFORE TOILET TRAINING. NO TRAINING WILL WORK IF THE CHILD IS NOT PHYSICALLY READY.

9. Cognition All mental activities associated with thinking, knowing and remembering.

10. Cognitive Development This field is Dominated by a man named Jean Piaget. He was developing IQ tests and noticed that many children got the same answers wrong. Thought to himself, “maybe these kids are not stupid, but instead think differently than adults.”

11. Piaget’s important concepts Children are active thinkers, always trying to make sense of the world. To make sense of the world, they develop schemas. Schema- a concept or framework that organizes and interprets information.

12. Piaget’s important concepts Assimilation- interpreting one’s new experiences into one’s existing schemas. Accommodation- adapting one’s current understandings (schemas) to incorporate new information.

13. Piaget’s Stages of Cognitive Development Sensorimotor Preoperational Concrete Operational Formal Operational

14. Sensorimotor Stage The Sensorimotor Stage is from approximately birth to 2 years of age. Babies take in the world purely through their senses- looking, hearing, touching, tasting and grasping.

15. Sensorimotor Stage At 4 to 8 months of age, your child will learn that she can make things move by banging them and shaking them. (Example--shaking a rattle, banging on toys, banging on tray of high chair)

16. Sensorimotor Stage Between 12 and 18 months your child will be able to represent hidden objects in her mind (Object Permanence). In other words, she will be able to “see” objects even when they are out of sight. Before Object Permanence- what is out of sight, is gone from the universe forever.

17. Sensorimotor Stage At 18 to 24 months of age, a child will begin to use images to stand for objects. In other words, a physical object can represent something else. Symbols represent objects or events in one’s own environment.

18. Preoperational Stage The Preoperational Stage is from approximately 2 to 7 years of age.

19. Preoperational Stage At the early part of this stage, a child will develop the ability to use symbols.

20. Preoperational Stage Between the ages of 3 and 4, your child will be able to apply this ability to symbolize with objects, to people (names represent people). habituation

21. Preoperational Stage By the end of this stage, the child will understand the concept of conservation.

22. Preoperational Stage Children in the preoperational stage are egocentric (the inability to take on another’s point of view).

23. Concrete Operational Stage 7-11 years old Understand concept of conservation. Can think logically, use analogies, and perform mathematical transformations (5+9 is the same as 9-5) also known as reversibility.
