Jean Piaget
He studied how kids think and learn
* Believed children’s thinking develops in stages
* Main stages:
Babies learn through touching and doing
Toddlers start using imagination
School kids start using logic
Teenagers can think about big ideas
Sigmund Freud
Sigmund Freud (Personality Development) ๐๏ธ
* Thought our childhood experiences shape our personality
* Believed we have three parts of our mind:
ID (wants instant fun)
EGO (tries to balance fun and rules)
SUPEREGO (our moral conscience)
* Talked about different stages of growing up based on pleasure
Erik Erikson
Erik Erikson (Social-Emotional Development) ๐
* Focused on how we develop emotionally throughout life
* Created stages from baby to old age
* Each stage has a challenge to overcome
* Example stages:
Babies need to feel safe and loved
Kids learn to be independent
Teenagers figure out who they are
Adults learn to care for others
Behavioral Theory
Behavioral Theory Basics ๐ง
* Focuses on how we learn through consequences
* Believes behavior can be changed by what happens after it
Behavioral Theory types of reinforcement
Positive Reinforcement (+) ๐
* Adding something good to INCREASE a behavior
* Example: Getting a sticker for cleaning your room
* Makes you want to clean more!
Negative Reinforcement (-) ๐ก๏ธ
* Removing something unpleasant to INCREASE a behavior
* Example: Taking pain medicine to stop a headache
* Makes you more likely to take medicine next time
Punishment ๐ซ
* Adding something unpleasant to DECREASE a behavior
* Example: Losing video game time for not doing homework
* Tries to stop a behavior from happening again
Extinction ๐ณ๏ธ
* Stopping a reward completely
* Example: Ignoring a child’s tantrum
* Behavior eventually stops because it gets no attention
Fun Fact: B.F. Skinner was the main scientist who developed these ideas! ๐๐ฌ
Piagetโs four stages of cognitive development
Sensorimotor
Preoperational
Concrete
Formal
Sensorimotor
Sensorimotor Stage (Birth - 2 years) ๐ถ
* Babies learn through touching, moving, and exploring
* Big discovery: Objects still exist even when they can’t see them
* Example: Peek-a-boo becomes fun!
* Key skill: Object permanence
Preoperational
Preoperational Stage (2 - 7 years) ๐ง
* Kids start using imagination and language
* Magical thinking is SUPER real
* Can’t see things from other people’s perspectives
* Love pretend play
* Example: Talking to stuffed animals like they’re real
Concrete
Concrete Operational Stage (7 - 11 years) ๐
* Start using logical thinking
* Can do math and understand rules
* Understand that things can change shape but still be the same
* Example: Knowing water in different shaped glasses is still the same amount
Formal
Formal Operational Stage (11 years - Adult) ๐ค
* Can think about abstract ideas
* Use logic for complex problems
* Can imagine hypothetical situations
* Think about big concepts like love, justice
* Example: Solving math problems without physical objects
Eriksonโs stages of Psychosocial Development
-Ego Integrity vs. Despair (Older Adult) ๐

* First period (menarche) around 12-13
* Hips widen
* Body fat increases
* Growth spurt earlier (10-12 years)
Hormonal Changes:
* Estrogen increases
* Ovaries start releasing eggs
* Emotional changes more intense
male puberty changes
MALE CHANGES ๐ฆ
Physical Changes:
* Testicle growth starts around 11-12
* Voice deepens
* Muscle mass increases
* Penis grows
* Facial/body hair appears
* Growth spurt later (12-14 years)

puberty SHARED CHANGES FOR BOTH

TYPES OF PLAY ๐ฎ
Functional Play ๐ถ
Symbolic Play ๐งธ
Constructive Play ๐งฉ
Games with Rules ๐
OBJECT PERMANENCE ๐
Understanding that objects exist even when you can’t see them
Piaget’s Stages of Object Permanence:
0-2 months: No understanding
2-4 months: Starts tracking moving objects
4-8 months: Partial understanding
8-12 months: Full object permanence
Peek-a-boo becomes super fun! ๐
EARLY LANGUAGE STAGES ๐ถ
Cooing (2 months)
* First vowel-like sounds
* Happy baby noises!
Babbling (6-9 months)
* Consonant + vowel sounds
* “Dada”, “Baba”
First Words (12-18 months)
* Simple words like “mama”, “dog”
* Receptive vocabulary > Expressive vocabulary
LANGUAGE DEVELOPMENT THEORIES ๐ง
mitation Theory (Social Cognitive) ๐ฆ
* Children learn by copying others
* Repeat words and sounds they hear
* Parents are the first language teachers!
Reinforcement Theory (B.F. Skinner) ๐
* Kids get rewarded for correct language
* Smiles, claps encourage more talking
* Incorrect words get less attention
Sensitive Period Theory ๐ฐ๏ธ
* Best time to learn language: 18-24 months
* Brain is super flexible
* Easier to learn multiple languages
