## Key Concepts

Part 2 of 7 — Key Concepts

1. UCS (unconditioned stimulus)

naturally triggers response (food)

2. UCR (unconditioned response)

natural response to UCS (salivation)

3. CS (conditioned stimulus)

neutral stimulus paired with UCS (bell)

4. CR (conditioned response)

learned response to CS (salivation to bell)

Concept Check 🎯

### Key Points

• UCS (unconditioned stimulus): naturally triggers response (food)
• UCR (unconditioned response): natural response to UCS (salivation)
• CS (conditioned stimulus): neutral stimulus paired with UCS (bell)
• CR (conditioned response): learned response to CS (salivation to bell)

## Acquisition & Extinction

Part 3 of 7 — Acquisition & Extinction

1. Acquisition

CS-UCS pairing builds the association

2. Extinction

CS presented alone → CR weakens

3. Spontaneous recovery

CR reappears after rest period

4. Higher-order conditioning

CS1 paired with CS2

Concept Check 🎯

### Key Points

• Acquisition: CS-UCS pairing builds the association
• Extinction: CS presented alone → CR weakens
• Spontaneous recovery: CR reappears after rest period
• Higher-order conditioning: CS1 paired with CS2

## Generalization & Discrimination

Part 4 of 7 — Generalization & Discrimination

1. Generalization

responding to similar stimuli

2. Discrimination

responding only to the specific CS

3. Little Albert experiment

Watson conditioned fear of white rat

4. Fear generalized to other furry objects

Fear generalized to other furry objects

Concept Check 🎯

### Key Points

• Generalization: responding to similar stimuli
• Discrimination: responding only to the specific CS
• Little Albert experiment: Watson conditioned fear of white rat
• Fear generalized to other furry objects
