Lesson 4: DEVELOPMENT AND LEARNING

🌱 DEVELOPMENT vs GROWTH vs MATURATION

🔄 TERM	💡 MEANING	📘 SITUATIONAL EXAMPLE
Development 🌈	Overall changes across the lifespan — includes physical, cognitive, emotional, and social aspects.	A child learns to walk (physical), speak (cognitive), play with others (social), and manage frustration (emotional). 👣🗣🤝💭
Growth 📏	Refers to physical, measurable changes in size, height, or weight.	A child grows 5 inches taller between ages 5 and 6. 📈👧
Maturation 🌿	The natural unfolding of biological potential, guided by genetics.	A baby starts walking around 12 months — not from teaching, but because their muscles and brain are ready. 👶🚶‍♀

💔 6 STAGES OF GRIEF (Kübler-Ross + Kessler Model)

💭 STAGE	📘 SITUATIONAL EXAMPLE
Denial 🙈	A person says, “This can’t be happening,” right after a breakup. 💬
Anger 😡	They lash out: “Why would they leave me? I didn’t deserve this!” 💢
Bargaining 🤝	“If I had just called them more, maybe we’d still be together.” 💔
Depression 😞	They avoid friends, lose interest in hobbies, and feel deep sadness. 🌧
Acceptance 🌤	“It still hurts, but I understand it’s over and I’m learning to move on.” 🌱
Finding Meaning ✨	They start volunteering for mental health causes in memory of the experience. 💖

📚 TYPES OF LEARNING

1⃣ Classical Conditioning (Pavlovian Conditioning) 🐶🔔

“Learning by Association” — Discovered by Ivan Pavlov. Occurs when a neutral stimulus becomes associated with a meaningful stimulus, eventually eliciting the same response.

📖 Example: A dog 🐶 learns to salivate at the sound of a bell 🔔 after the bell has been repeatedly paired with food 🍖.

💬 Term	🧩 Meaning	📘 Example
Unconditioned Stimulus (UCS)	Naturally occurring stimulus that leads to an involuntary (reflex) response.	Food that makes a dog salivate 🍖
Unconditioned Response (UCR)	The involuntary response to the UCS.	Dog salivates naturally when it sees food 🐶💧
Neutral Stimulus (NS)	A stimulus that initially has no effect on the response.	The sound of a bell 🔔 before conditioning
Conditioned Stimulus (CS)	A previously neutral stimulus that, after being paired with the UCS, triggers a learned response.	The bell sound after being associated with food 🔔🍖
Conditioned Response (CR)	The learned reflex response to the CS.	Dog salivates at the sound of the bell 🔔💧

🎯 Human Example: You start to feel hungry every time you hear the sound of a microwave because it’s often followed by food 🍕.

2⃣ Operant Conditioning (Skinnerian Conditioning) 🐭🎯

“Learning through Rewards and Punishments” — Developed by B.F. Skinner, it’s based on how consequences shape behavior.

✅ Behaviors followed by reinforcement are likely to be repeated.
❌ Behaviors followed by punishment are less likely to occur.

⚖ Concept	💡 Definition	📘 Example
Law of Effect (Thorndike)	Behaviors followed by pleasant outcomes are repeated; unpleasant ones are avoided.	A cat in a puzzle box learns to press a lever 🐱🔲 faster when it leads to food.
Positive Reinforcement	Adding a pleasant stimulus to encourage behavior.	You get ₱100 💵 for cleaning your room — you’ll clean again next time.
Negative Reinforcement	Removing an unpleasant stimulus to encourage behavior.	You wear your seatbelt to stop the car’s beeping sound 🚗🔕.
Positive Punishment	Adding something unpleasant to reduce behavior.	You talk back → get extra chores 🧹.
Negative Punishment	Taking away something pleasant to reduce behavior.	You talk back → your phone gets taken away 📱.

🕒 Schedules of Reinforcement

⏰ Schedule Type	💬 Description	📘 Example
Fixed Interval	Reinforcement after a fixed time period.	You get paid every 2 weeks 💰.
Variable Interval	Reinforcement after varying time intervals.	Checking your email 📩 — sometimes a message is there, sometimes not.
Fixed Ratio	Reinforcement after a fixed number of responses.	A factory worker gets paid after sewing 10 shirts 👕.
Variable Ratio	Reinforcement after an unpredictable number of responses.	Slot machines 🎰 — you never know when you’ll win.

🎯 Human Example: You study harder when you know there’s a pop quiz coming, because you’re rewarded with good grades 🏅.

3⃣ Observational Learning (Social Learning / Modeling) 👀🧍‍♀🧍‍♂

Proposed by Albert Bandura. Learning occurs by watching and imitating others instead of through direct experience.

🧩 Process	💡 Description	📘 Example
Attention	The observer must notice the model’s behavior.	A child watches their older sibling cook 🍳.
Retention	The observer must remember the behavior.	The child remembers how to crack an egg 🥚.
Reproduction	The observer must be capable of doing it.	The child tries cooking the same meal 👩‍🍳.
Motivation	The observer needs a reason to imitate.	The child gets praised for helping, so they do it again 🌟.

🧸 Bobo Doll Experiment (1961) — Children who watched adults act aggressively toward a Bobo doll later imitated that same aggression. 😡➡👶

4⃣ Cognitive Learning 🧩📚

Focuses on mental processes such as thinking, understanding, and remembering — not just visible behaviors.

🧠 Theory	💬 Description	📘 Example
Piaget’s Theory of Cognitive Development	Children actively construct knowledge through experience and interaction 🌍.	A child learns that pressing buttons on a remote changes TV channels 📺.
Vygotsky’s Theory of Cognitive Development	Emphasizes social interaction and the Zone of Proximal Development (ZPD) — learning happens best with guidance 🤝.	A student learns math faster when a teacher or peer helps explain it step-by-step ➕📚.

🎯 Human Example: Solving puzzles 🧩 or learning a new skill by understanding the process, not just copying actions.
