Okay, so today I decided to mess around with the whole “light and shadow” thing in AP Psychology. I’ve always been kind of a visual learner, so I figured actually seeing it would help me understand it better.
Setting Up
First, I gathered my supplies. Basically, I just grabbed a lamp, some random objects from around my room (a book, a water bottle, a small toy dinosaur – you know, the essentials), and a blank wall. I made sure the room was pretty dark, so the lamp would be the main light source.
The Experiment (aka Playing Around)
I started by shining the lamp directly at the book. This created a really harsh shadow, super defined and dark. It was pretty obvious where the light was coming from, and the book looked almost two-dimensional.
- I noticed how the shadow got bigger or smaller depending on how close the book was to the lamp. Closer = bigger shadow, further away = smaller shadow. Makes sense, right?
Then, I tried moving the lamp around. When I put it off to the side, the shadow stretched out and got all distorted. It was way less clear where the light source was, and the book looked more three-dimensional. Kinda cool, actually.

I played with different angles. Lamp above the object? Short, stubby shadow. Lamp below? Long, creepy shadow that went up the wall.
Next, I switched out the book for the water bottle. Since it’s see-through, the light went through it in some places, creating lighter areas within the shadow. And the toy dinosaur? All those little bumps and ridges made for a really interesting, textured shadow.
What I Learned (aka The Psychology Part)
So, besides having some fun with shadows, I realized a few things that actually connect to AP Psych:
- Depth Perception: Seeing how the shadows changed with the light’s position really showed me how our brains use light and shadow to judge distance and depth. That harsh, direct light made things look flatter, while the angled light gave a better sense of 3D.
- Monocular Cues: This whole thing is basically a demonstration of monocular cues – the stuff we use to see depth with just one eye. Specifically, it’s about “light and shadow” as a cue.
- It is interesting.
Honestly, messing around with this stuff myself made it way easier to understand than just reading about it in the textbook. I recommend giving it a try if you’re also struggling with this concept. Plus, it’s an excuse to play with a lamp and a toy dinosaur. Win-win!
