Alright, let’s talk about sodas in AP Psychology. Yeah, sodas, like Coca-Cola and stuff. You might be thinking, “What does sugary fizz have to do with psychology?” Well, buckle up, because I’m gonna walk you through how I used them to understand some key concepts.

It all started when I was reviewing the chapter on classical conditioning. You know, Pavlov’s dogs and all that. I was struggling to really grasp how a neutral stimulus becomes a conditioned stimulus. So, I thought, “Hey, why not make it relatable?”
First, I grabbed a can of my favorite soda – let’s say it was Sprite. This was my unconditioned stimulus (UCS). The taste of Sprite naturally elicits happiness and refreshment – that’s my unconditioned response (UCR). Simple enough, right?
Then, I picked something totally neutral: a specific song on my phone. Like, some random elevator music type stuff. This was my neutral stimulus (NS). It didn’t make me feel anything in particular.
Here’s where the fun started. For a week, every single time I cracked open that can of Sprite, I played that song. EVERY. SINGLE. TIME. I paired the NS (the song) with the UCS (the Sprite).

After a few days, I started to notice something. I played the song WITHOUT drinking Sprite, and guess what? I started to feel a little bit of that same happiness and refreshment, even though I wasn’t actually drinking the soda! The song, which was originally neutral, had become a conditioned stimulus (CS). It was now triggering a conditioned response (CR) – a feeling similar to the one I got from the Sprite itself.
I pushed it further. I wanted to see about extinction. I kept playing the song repeatedly, but WITHOUT the Sprite. Slowly, over time, the association faded. The song stopped triggering that feeling of happiness. The conditioned response was extinguished.
And then, just to be extra sure, a few days later I played the song again… bam! Spontaneous recovery! The feeling came back, though not as strongly as before. It was wild to experience it firsthand.
What I Learned

- Classical conditioning isn’t just about dogs salivating. You can see it in everyday life, even with soda.
- Experimenting is way more effective than just reading. Actually doing it made the concepts stick.
- It’s a pretty good excuse to drink soda. (Just kidding… mostly.)
I tried this with different sodas and different stimuli. I even tried aversion therapy by pairing a soda I liked with watching a really boring documentary, aiming to reduce my desire for that soda. It kind of worked, but mostly just made me hate the documentary.
So, there you have it. Sodas, psychology, and a little bit of weird personal experimentation. It definitely helped me understand classical conditioning, and maybe it’ll help you too! Give it a shot (with parental permission if you’re underage, of course). Just remember to brush your teeth afterwards.
