Have you ever wondered why some days you remember things easily, while on others you keep forgetting? Or why certain songs make you super happy and others just…meh?
Our minds are like big, mysterious puzzles, and every day we’re finding new pieces to fit. One of the coolest ways to explore our brains and the way they work is through psychology experiments.
A psychology experiment is a special kind of test or activity researchers use to learn more about how our minds work and why we behave the way we do.
It’s like a detective game where scientists ask questions and try out different clues to find answers about our feelings, thoughts, and actions. These experiments aren’t just for scientists in white coats but can be fun activities we all try to discover more about ourselves and others.
Some of these experiments have become so famous, they’re like the celebrities of the science world! Like the Marshmallow Test, where kids had to wait to eat a yummy marshmallow, or Pavlov’s Dogs, where dogs learned to drool just hearing a bell.
Let’s look at a few examples of psychology experiments you can do at home.

The Marshmallow Test
The goal was simple but profound: to understand a child’s ability todelay gratificationand exercise self-control.
Children were placed in a room with a marshmallow and given a choice: eat the marshmallow now or wait 15 minutes and receive two as a reward. Many kids struggled with the wait, some devouring the treat immediately, while others demonstrated remarkable patience.
But the experiment didn’t end there. Years later, Mischel discovered something astonishing. The children who had waited for the second marshmallow were generally more successful in several areas of life, from school achievements to job satisfaction!
While this experiment highlighted the importance of teaching patience and self-control from a young age, it wasn’t without its criticisms. Some argued that a child’s background, upbringing, or immediate surroundings might play a significant role in their choices.
Moreover, there were concerns about the ethics of judging a child’s potential success based on a brief interaction with a marshmallow.
Pavlov’s Dogs
Pavlov came up with the termclassical conditioning, which is still used today. Other psychologists have developed more nuanced types of conditioning that help us understand how people learn to perform different behaviours.
Modern thinkers often critique Pavlov’s methods from an ethical standpoint. The dogs, crucial to his discovery, may not have been treated with today’s standards of care and respect in research.
Both these experiments, while enlightening, also underline the importance of conducting research with empathy and consideration, especially when it involves living beings.
The tales of Pavlov’s bells and Mischel’s marshmallows offer us not just insights into the human mind and behavior but also raise a significant question: At what cost do these discoveries come?
Ethical experimentation isn’t just a fancy term; it’s the backbone of good science. When we talk about ethics, we’re referring to the moral principles that guide a researcher’s decisions and actions. But why does it matter so much in the realm of psychological experimentation?
An example of an experiment that had major ethical issues isan experiment called the Monster Study. This study was conducted in 1936 and was interested in why children develop a stutter.
The major issue with it is that the psychologists treated some of the children poorly over a period of five months, telling them things like “You must try to stop yourself immediately. Don’t ever speak unless you can do it right.”
You can imagine how that made the children feel!
This study helped create guidelines for ethical treatment in experiments. The guidelines include:
Respect for Individuals:Whether it’s a dog in Pavlov’s lab or a child in Mischel’s study room, every participant—human or animal—deserves respect. They should never be subjected to harm or undue stress. For humans,informed consent(knowing what they’re signing up for) is a must. This means that if a child is participating, they, along with their guardians, should understand what the experiment entails and agree to it without being pressured.
Safety First:No discovery, no matter how groundbreaking, is worth harming a participant. The well-being and mental, emotional, and physical safety of participants is paramount. Experiments should be designed to minimize risks and discomfort.
Considering the Long-Term:Some experiments might have effects that aren’t immediately obvious. For example, while a child might seem fine after participating in an experiment, they could feel stressed or anxious later on. Ethical researchers consider and plan for these possibilities, offering support and follow-up if needed.
The Rights of Animals:Just because animals can’t voice their rights doesn’t mean they don’t have any. They should be treated with care, dignity, and respect. This means providing them with appropriate living conditions, not subjecting them to undue harm, and considering alternatives to animal testing when possible.
While the world of psychological experiments offers fascinating insights into behavior and the mind, it’s essential to tread with care and compassion. The golden rule?Treat every participant, human or animal, as you’d wish to be treated.After all, the true mark of a groundbreaking experiment isn’t just its findings but the ethical integrity with which it’s conducted.
So, even if you’re experimenting at home, please keep in mind the impact your experiments could have on the people and beings around you!
Let’s get into some ideas for experiments.
Our primary aim with this experiment is to explore the intriguing world of social influences, specifically focusing on how much sway a group has over an individual’s decisions. This social influence is calledgroupthink.
Humans, as social creatures, often find solace in numbers, seeking the approval and acceptance of those around them. But how deep does this need run? Does the desire to “fit in” overpower our trust in our own judgments?
This experiment not only provides insights into these questions but also touches upon the broader themes of peer pressure, societal norms, and individuality. Understanding this could shed light on various real-world situations, from why fashion trends catch on to more critical scenarios like how misinformation can spread.
Real-World Impacts of Groupthink
Groupthink is more than just a science term; we see it in our daily lives:
Decisions at Work or School:Imagine being in a group where everyone wants to do one thing, even if it’s not the best idea. People might not speak up because they’re worried about standing out or being the only one with a different opinion.
Wrong Information:Ever heard a rumor that turned out to be untrue? Sometimes, if many people believe and share something, others might believe it too, even if it’s not correct. This happens a lot on the internet.
Peer Pressure:Sometimes, friends might all want to do something that’s not safe or right. People might join in just because they don’t want to feel left out.
Missing Out on New Ideas:When everyone thinks the same way and agrees all the time, cool new ideas might never get heard. It’s like always coloring with the same crayon and missing out on all the other bright colors!

We all have favorite colors, right? But did you ever wonder if colors can make you feel a certain way?Color psychologyis the study of how colors can influence our feelings and actions.
For instance, does blue always calm us down? Does red make us feel excited or even a bit angry? By exploring this, we can learn how colors play a role in our daily lives, from the clothes we wear to the color of our bedroom walls.
Method:
Researchers have always been curious about this. Some studies have shown that colors like blue and green can make people feel calm, while colors like red might make them feel more alert or even hungry!
Real-World Impacts of Color Psychology
Ever noticed how different places use colors?
Hospitals and doctors' clinics often use soft blues and greens. This might be to help patients feel more relaxed and calm.
Many fast food restaurants use bright reds and yellows. These colors might make us feel hungry or want to eat quickly and leave.
Classrooms might use a mix of colors to help students feel both calm and energized.
Think about your favorite song. Do you feel smarter or more focused when you listen to it? This experiment seeks to understand the relationship between music and our brain’s ability to remember things. Some people believe that certain types of music, like classical tunes, can help us study or work better. Let’s find out if it’s true!
The “Mozart Effect” is a popular idea. Some studies in the past suggested that listening to Mozart’s music might make people smarter, at least for a little while. But other researchers think the effect might not be specific to Mozart; it could be that any music we enjoy boosts our mood and helps our brain work better.
Real-World Impacts of Music and Memory
Think about how we use music:
Ever had a really wild dream and wondered where it came from? Some say that eating certain foods before bedtime can make our dreams more vivid or even a bit strange.
This experiment is all about diving into the dreamy world of sleep to see if what we eat can really change our nighttime adventures. Can a piece of chocolate or a slice of cheese transport us to a land of wacky dreams? Let’s find out!
The link between food and dreams isn’t super clear, but some people have shared personal stories. For example, some say that spicy food can lead to bizarre dreams. Scientists aren’t completely sure why, but it could be related to how food affects our body temperature or brain activity during sleep.
A cool idea related to this experiment is that ofvivid dreams, which are very clear, detailed, and easy to remember dreams. Some people are even able to control their vivid dreams, or say that theyfeel as real as daily, waking life!
Real-World Impacts of Food and Dreams
Our discoveries might shed light on:
Stand in front of a mirror. How do you feel? Proud? Shy? Curious? Mirrors reflect more than just our appearance; they might influence how we think about ourselves.
This experiment delves into the mystery of self-perception. Do we feel more confident when we see our reflection? Or do we become more self-conscious? Let’s take a closer look.
Studies have shown that when people are in rooms with mirrors, they can become more aware of themselves. Some might stand straighter, fix their hair, or even change how they behave. The mirror acts like an audience, making us more conscious of our actions.
Real-World Impacts of Mirrors and Self-perception
Mirrors aren’t just for checking our hair. Ever wonder why clothing stores have so many mirrors? They might help shoppers visualize themselves in new outfits, encouraging them to buy.
Mirrors in gyms can motivate people to work out with correct form and posture. They also help us see progress in real-time!
And sometimes, looking in a mirror can be a reminder to take care of ourselves, both inside and out.
But remember, what we look like isn’t as important as how we act in the world or how healthy we are. Some people claim that having too many mirrors around can actually make us more self conscious and distract us from the good parts of ourselves.
Some studies are showing thatmirrors can actually increase self-compassion, amongst other things. As any tool, it seems like mirrors can be both good and bad, depending on how we use them!

Have you ever seen someone talking to their plants? It might sound silly, but some people believe that plants can “feel” our vibes and that talking to them might even help them grow better.
In this experiment, we’ll explore whether plants can indeed react to our voices and if they might grow taller, faster, or healthier when we chat with them.
The idea isn’t brand new. Some experiments from the past suggest plants might respond to sounds or vibrations. Some growers play music for their crops, thinking it helps them flourish.
Even if talking to our plants doesn’t have an impact on their growth, it can make us feel better! Sometimes, if we are lonely, talking to our plants can help us feel less alone. Remember, they are living too!
Real-World Impacts of Talking to Plants
If plants do react to our voices, gardeners and farmers might adopt new techniques, like playing music in greenhouses or regularly talking to plants.
Taking care of plants and talking to them could become a recommended activity for reducing stress and boosting mood.
And if plants react to sound, it gives us a whole new perspective onhow connected all living things might be.
Virtual reality (VR) seems like magic, doesn’t it? You put on a headset and suddenly, you’re in a different world! But how does this “new world” affect our senses? This experiment wants to find out how our brains react to VR compared to the real world. Do we feel, see, or hear things differently? Let’s get to the bottom of this digital mystery!
As VR becomes more popular, scientists have been curious about its effects. Some studies show that our brains can sometimes struggle to tell the difference between VR and reality. That’s why some people might feel like they’re really “falling” in a VR game even though they’re standing still.
Real-World Impacts of VR on Our Senses
Schools might use VR to teach lessons, like taking students on a virtual trip to ancient Egypt. Understanding how our senses react in VR can also help game designers create even more exciting and realistic games.
Doctors could use VR tohelp patients overcome fearsor to provide relaxation exercises. This is actually already a method therapists can use for helping patients who have serious phobias. This is calledexposure therapy, which basically means slowly exposing someone (or yourself) to the thing you fear, starting from very far away to becoming closer.
For instance, if someone is afraid of snakes. You might show them images of snakes first. Once they are comfortable with the picture, they can know there is one in the next room. Once they are okay with that, they might use a VR headset to see the snake in the same room with them, though of course there is not an actual snake there.
We all know that feeling of trying to study or work when we’re super tired. Our brains feel foggy, and it’s hard to remember stuff. But how exactly does sleep (or lack of it) influence our ability to learn and remember things?
With this experiment, we’ll uncover the mysteries of sleep and see how it can be our secret weapon for better learning.
Sleep and its relation to learning have been explored a lot. Scientists believe that during sleep, especially deep sleep, our brains sort and store new information. This is why sometimes, after a good night’s rest, we might understand something better or remember more.
Real-World Impacts of Sleep and Learning
Understanding the power of sleep can help:
Have you ever felt different after spending time on social media? Maybe happy after seeing a friend’s fun photos, or a bit sad after reading someone’s tough news.
Previous research has shown mixed results. Some studies suggest that seeing positive posts can make us feel good, while others say that too much time on social media can make us feel lonely or left out.
Real-World Impacts of Social Media on Mood
Understanding the emotional impact of social media can help users understand their feelings and take breaks if needed. Knowing is half the battle! Additionally, teachers and parents can guide young users on healthy social media habits, like limiting time or following positive accounts.
And if it’s shown that social media does impact mood, social media companies can design friendlier, less stressful user experiences.
But even if the social media companies don’t change things, we can stillchange our social media habitsto make ourselves feel better.
Think about the last time you took notes. Did you grab a pen and paper or did you type them out on a computer or tablet?
Both ways are popular, but there’s a big question: which method helps us remember and understand better? In this experiment, we’ll find out if the classic art of handwriting has an edge over speedy typing.
Studies have shown some interesting results. While typing can be faster and allows for more notes, handwriting might boost memory and comprehension because it engages the brain differently, making us process the information as we write.
Importantly, each person might find one or the other works better for them. This could be useful in understanding our learning habits and whatinstructional stylewould be best for us.
Real-World Impacts of Handwriting vs. Typing
Knowing the pros and cons of each method can:

We often hear the saying, “Money can’t buy happiness,” but is that really true? Many dream of winning the lottery or getting a big raise, believing it would solve all problems.
In this experiment, we dig deep to see if there’s a real connection between wealth and well-being.
Some studies have found money can boost happiness, especially when it helps people out of tough financial spots. But after reaching a certain income, extra dollars usually do not add much extra joy.
In fact, psychologists just realized that once people have an income that can comfortably support their needs (and some of their wants), theystop getting happier with more. That number is roughly $75,000, but of course that depends on the cost of living and how many members are in the family.
Real-World Impacts of Money and Happiness
If we can understand the link between money and joy, it might help folks choose jobs they love over jobs that just pay well. And instead of buying things, people might spend on experiences, like trips or classes, that make lasting memories.
Most importantly, we all might spend more time on hobbies, friends, and family, knowing they’re big parts of what makes life great.
Some people are hoping that with Artificial Intelligence being able to do a lot of the less well-paying jobs, people might be able to do work they enjoy more, all while making more money and having more time to do the things that make them happy.
Have you ever noticed how a cold classroom or office makes it harder to focus? Or how on hot days, all you want to do is relax? In this experiment, we’re going to find out if the temperature around us really does change how well we work.
Some studies have shown that people can work better when they’re in a room that feels just right, not too cold or hot. Being too chilly can make fingers slow, and being too warm can make minds wander.
What temperature is “just right”? It won’t be the same for everyone, but most people find it’s between 70-73 degrees Fahrenheit (21-23 Celsius).
Real-World Implications of Temperature and Productivity
If we can learn more about how temperature affects our work, teachers might set classroom temperatures to help students focus and learn better, offices might adjust temperatures to get the best work out of their teams, and at home, we might find the best temperature for doing homework or chores quickly and well.
Interestingly,temperature also has an impact on our sleepquality. Most people find slightly cooler rooms to be better for good sleep. While the daytime temperature between 70-73F is good for productivity, a nighttime temperature around 65F (18C) is ideal for most people’s sleep.
Psychology is like a treasure hunt, where the prize is understanding ourselves better. With every experiment, we learn a little more about why we think, feel, and act the way we do. Some of these experiments might seem simple, like seeing if colors change our mood or if being warm helps us work better. But even the simple questions can have big answers that help us in everyday life.
Remember, while doing experiments is fun, it’s also important to always be kind and think about how others feel. We should never make someone uncomfortable just for a test. Instead, let’s use these experiments to learn and grow, helping to make the world a brighter, more understanding place for everyone.
