Let’s go step by step through each scenario. We’ll identify:

- NS (Neutral Stimulus) – something that doesn’t cause a response at first.
- UCS (Unconditioned Stimulus) – something that naturally causes a response (no learning needed).
- UCR (Unconditioned Response) – the natural, automatic reaction to the UCS.
- CS (Conditioned Stimulus) – originally neutral, but after pairing with UCS, it starts causing a response.
- CR (Conditioned Response) – the learned response to the CS.

Also remember:
> If it has a ‘U’ in front, it must be natural (not learned).
> The NS and CS should be the same thing — just before and after learning.
> The UCR and CR are usually similar responses.

Scenario 1: John and the red balloon

What happened?
- John loves balloons → no fear at first.
- One day, red balloon pops → loud noise → he cries (natural reaction).
- Now, just seeing a red balloon makes him cry.

So:

→ Before conditioning:
- NS: Red balloon (didn’t scare him before)
- UCS: Loud pop (naturally scary)
- UCR: Crying (natural reaction to loud noise)

→ After conditioning:
- CS: Red balloon (now triggers crying because it was paired with the pop)
- CR: Crying (learned response to red balloon)

Note: The worksheet says “Balloon burst = crying” under UCS=UCR — that’s correct for the unconditioned part. But we need to fill in all boxes properly.

First box: NS = ? , UCS = ?
→ NS = Red balloon (before learning, it meant nothing scary)
→ UCS = Loud pop (causes crying naturally)

Second box: NS + UCS = UCR
→ Red balloon + Loud pop = Crying

Third box: CS = CR
→ CS = Red balloon (now triggers crying)
→ CR = Crying

✔ So final answers for #1:
- NS = Red balloon
- UCS = Loud pop
- UCR = Crying
- CS = Red balloon
- CR = Crying

*(Note: The worksheet already wrote “Balloon burst=crying” under UCS=UCR — that’s acceptable if they mean the pop is the stimulus and crying is the response. But technically, “balloon burst” includes both the visual and sound — better to separate them. However, since the problem says “the loud noise upset him”, we’ll use “loud pop” as UCS.)*

But looking at how the worksheet is set up, they may expect:

In first box:
NS = Red balloon
UCS = Loud noise (or balloon popping)
UCR = Crying

Then second box: NS+UCS=UCR → Red balloon + Loud noise = Crying

Third box: CS=CR → Red balloon = Crying

That works.

Scenario 2: Rastus the dog and motorbike keys

What happened?
- Rastus loves riding on tractor → wags tail when owner walks toward motorbike (because that means ride!).
- Now, just picking up motorbike keys makes him wag tail.

So:

→ Before conditioning:
- NS: Motorbike keys (didn’t mean anything special at first)
- UCS: Walking toward motorbike / getting ready for ride (naturally exciting → tail wag)
- UCR: Tail wagging (happy/excited response)

→ After conditioning:
- CS: Motorbike keys (now triggers tail wagging)
- CR: Tail wagging (learned response to keys)

Fill in boxes:

First box:
NS = Motorbike keys
UCS = Owner walking toward motorbike (or preparing for ride)
UCR = Tail wagging

Second box: NS + UCS = UCR → Keys + Walk to motorbike = Tail wagging

Third box: CS = CR → Keys = Tail wagging

✔ Final for #2:
- NS = Motorbike keys
- UCS = Owner walking toward motorbike (or starting ride)
- UCR = Tail wagging
- CS = Motorbike keys
- CR = Tail wagging

*(Note: Some might say “tractor ride” is the UCS — but the trigger is the owner walking toward the motorbike, which signals the ride. Since the key pickup now triggers it, the original signal was the walk toward motorbike.)*

Scenario 3: Nadine and Oprah theme song

What happened?
- Nadine watches Oprah during holidays → eats snack → salivates (natural response to food).
- Now, just hearing the theme song makes her salivate.

So:

→ Before conditioning:
- NS: Oprah theme song (just music — didn’t make her salivate at first)
- UCS: Snack/food (naturally causes salivation)
- UCR: Salivating (automatic response to food)

→ After conditioning:
- CS: Oprah theme song (now triggers salivation)
- CR: Salivating (learned response to the song)

Fill in boxes:

First box:
NS = Oprah theme song
UCS = Snack (or food)
UCR = Salivating

Second box: NS + UCS = UCR → Theme song + Snack = Salivating

Third box: CS = CR → Theme song = Salivating

✔ Final for #3:
- NS = Oprah theme song
- UCS = Snack (or food)
- UCR = Salivating
- CS = Oprah theme song
- CR = Salivating

---

Now let’s write the final answers clearly for each scenario as required by the worksheet format.

The worksheet has three scenarios, each with three boxes:

Box 1: NS = ?, UCS = ?
Box 2: NS + UCS = UCR
Box 3: CS = CR

We’ll fill them accordingly.

---

Final Answer:

Scenario 1:
- Box 1: NS = Red balloon, UCS = Loud pop
- Box 2: Red balloon + Loud pop = Crying
- Box 3: CS = Red balloon, CR = Crying

Scenario 2:
- Box 1: NS = Motorbike keys, UCS = Owner walking toward motorbike
- Box 2: Motorbike keys + Owner walking toward motorbike = Tail wagging
- Box 3: CS = Motorbike keys, CR = Tail wagging

Scenario 3:
- Box 1: NS = Oprah theme song, UCS = Snack
- Box 2: Oprah theme song + Snack = Salivating
- Box 3: CS = Oprah theme song, CR = Salivating

*(Note: For simplicity and matching common textbook examples, you can also write “Food” instead of “Snack” in #3, and “Loud noise” instead of “Loud pop” in #1 — both are acceptable.)*
