Measure Human Perception Science Projects (16 results)

Measure human perception, the ability of people to use their senses and remember what they've experienced. Collect data about the score volunteers get on a test, the time it takes them to do a task, or percentage of volunteers who have certain characteristics.

Are Your Eyes Playing Tricks on You? Discover the Science Behind Afterimages!
Science Fair Project Idea
Scientific Method
Yogi Berra said "You can observe a lot by just watching." In this human biology science fair project, you will observe how your eyes perceive color by watching afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. You will also learn how different cone cells in your retina respond to different colors.

What Conflicting Mental Tasks Reveal About Thinking: The Stroop Effect
Science Fair Project Idea
Scientific Method
Can you pat your head with one hand while you rub your stomach with the other? This science project idea is kind of like doing that, but this project can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough, but see what happens when color words get in the way. Read more
Mixing Light to Make Colors
Science Fair Project Idea
Scientific Method
You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more
Now You See It, Now You Don't: A Chromatic Adaptation Project
Science Fair Project Idea
Scientific Method
This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! Read more
Warped Words and the Stroop Effect
Science Fair Project Idea
Scientific Method
The Stroop effect describes an experiment about the time it takes to name the color of printed words. When you try to name the color in which color words are printed, it takes longer when the color word differs from the ink color than when the color word is the same as the ink color. This project is an interesting variation: what happens if you 'warp' the words into a curved shape that is harder to recognize as a word? Will the Stroop effect still happen? How 'warped' do the words have to be in… Read more
Apparent Motion & Animation
Science Fair Project Idea
Scientific Method
Have you ever heard the phrase, "Seeing is believing"? Well, it is more accurate than you might think! In this science project, you can investigate the phenomenon of apparent motion by making your own flip-book animations Read more
How Many Numbers Can You Remember?
Science Fair Project Idea
Scientific Method
Are you good at remembering addresses and phone numbers? How many numbers do you think you can remember? Try this experiment to test your digit span, the maximum number of digits that you can remember. Read more
The Brains Behind 'Where's Waldo?'
Science Fair Project Idea
Scientific Method
What makes you notice someone in a crowd? Why do some things stand out, while others melt into the background? In this science project you can investigate the psychology of how things get noticed, by studying how our brains perform a visual search. Have you ever looked and looked desperately for something? It is so frustrating! The classic example is when I lose my keys. You would think that by now (knowing that I am the kind of person who often loses my keys) I would have a huge, bright red… Read more
Shaping Your Thoughts?
Science Fair Project Idea
Scientific Method
This is an interesting experiment that explores certain aspects of how your brain pays attention. In this project, you'll have to recruit a bunch of volunteers to take a simple test: naming a list of printed shapes. What makes the test tricky is that words will be printed on top of the shapes. The word/shape combination creates the potential for the brain to get conflicting information. Which information is more likely to grab your attention: the shape you are supposed to name or the word just… Read more
I See a Full Moon Rising...and Shrinking...or Do I?
Science Fair Project Idea
Scientific Method
Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this human biology science fair project, you will investigate Emmert's law, which explains the full moon illusion. You will estimate the size of the perceived increase in the size of the moon at the horizon. Read more
