The world of psychology revealed by Professor Yoshihito Naito, a leading expert in practical psychology.
"A fun and easy-to-read dictionary of psychology with 67 topics."


Psychologist Yoshihito Naito, who captured the hearts of many adults with “Just Change Your Tone of Speaking,” has now published a psychology book for teenagers.
If you vaguely thought, “Isn’t psychology the study of reading other people’s minds?” this book will completely change your mind.
It is an interesting and friendly explanation of what psychology is and how it is deeply connected to our daily lives.
It is structured so that anyone from elementary school students to adults can easily read and understand it, making it a good introductory book to psychology.
Psychology, like biology or astronomy, is a discipline that aims to understand the world, but it is special in that its subject is 'ourselves'.

Anyone going through puberty has probably asked themselves these questions at least once - "Are looks everything when it comes to dating?", "Is it a disadvantage to have a quiet personality?", "Will I really be happy if I do what I love?", "What should I do if I'm a victim of cyberbullying?", "Can I tell if someone is successful through Instagram?" - This book provides clear and practical answers to these questions from a psychological perspective.
As you read, you will find yourself exclaiming, “I didn’t know psychology could be such a fun and useful subject?”

The book is divided into six themes: 'Family and Friends', 'Love and Sex', 'Study and Sports', 'Money and Career', 'Society and the Future', and 'Lies and Truth'.
For each topic, we provide easy and fun explanations of topics that teenagers might be curious about, based on the latest psychological research from around the world.
It introduces various psychological theories such as the six degrees of separation theory, the contagion effect, and the halo effect, so you can use it as a dictionary by selecting only the topics of interest.

Above all, what makes this book special is that it goes beyond simply imparting knowledge. It deeply empathizes with the real-world concerns of teenagers and offers solutions. Focusing on real-life issues faced by teenagers, such as social media, appearance concerns, school violence, and cyberbullying, it demonstrates how psychology can be a life-changing tool.

"Why Is My Heart Like This?" is an introductory psychology book that helps teenagers better understand themselves and develop perspectives on others just by reading it.
This book will serve as the first step toward helping young people grow into healthy members of society.
This is a must-read for teenagers, as well as their parents and teachers who want to understand their hearts.

Into the book
Unfortunately, bullying is common in schools, workplaces, and other communities where people gather.
If you see someone around you being bullied, don't hesitate, step forward and help.
Psychological research shows that when you hesitate and hesitate, thinking, "Should I start a conversation? What should I do?", most people end up choosing to just "stay still."
When helping, you should just reflexively jump in and say to the perpetrator, “Hey, don’t do that!”
Or, it would be good to listen to the victim and say, “If you’re having a hard time, I’ll give you some advice.”

Why do women want to be so thin? Perhaps the media has a big influence.
All models and celebrities are slim.
There are some chubby celebrities, but most of them are comedians.
If you come into contact with this kind of mass media every day, you will subconsciously start to think, 'I should become slim like model ○○.'
As I explained about 'mean and standard deviation' earlier, if you look at the data, there are many women who are not fat.
So don't try too hard to follow what you see in the media.
Celebrities and models are only 'exceptional' situations, and in reality, there is no need to lose that much weight as long as there are no health problems.

Sometimes, better results are achieved when players train and compete freely rather than under the supervision of a coach.
This may not be the case for all teams, but it is clear that it is easier to perform well when you approach the game with a relaxed and calm attitude.
Basically, you should follow what the coach and manager say, but if you really can't agree with something, just let it go.
Leaders are also human, so they sometimes make mistakes or misjudge things.
If the player does not understand and enjoy the game, good performance will not be achieved.

Since you won't know what's important without looking at past exam questions, you'll have no choice but to memorize every subject from the beginning.
Then, the amount of material you have to memorize increases significantly and learning efficiency decreases.
For efficient and smooth learning, please remember to start with solving past exam questions.

When studying, it is a good idea to divide the content into several chunks and memorize them.
For example, if there are 100 pieces of knowledge, similar or related ones are grouped together and made into five or ten categories.
This will also help you remember it.

Stuart McCann of Cape Breton University in Canada has published a surprising study showing that you can predict a person's success by looking at their X (formerly Twitter) account.
McCann analyzed the tweets of more than 140,000 people and also looked into the social status and financial income of those accounts.
As a result, we found that the more positive the tweets, the higher the position and income of the person in the company.
Rich and successful people don't complain or gossip about others.

Why do scary ghost stories make people want to share them? According to Heath, it's because they "have high survival value."
For example, if you hear something like, “It’s dangerous there, so you shouldn’t go near it,” you can be careful in advance and reduce the risk of your life being in danger.
We shouldn't incite unnecessary anxiety or fear, but psychologically, everyone wants to live in peace and safety, so rumors that are life-threatening tend to spread easily and be believed easily.

Publisher's Review
Psychology is now an elective subject taught in high schools.
This means that the importance of psychology and interest in it are growing.
The fact that the MBTI personality type test, which was created based on the psychological theory of Carl Gustav Jung, has become so popular in Korea also shows that the need to understand oneself through psychology is growing stronger.
