Chapter 1: The Entrance to Psychology – A Map to Unravel the Wonders of the Mind
1.1 What is "the science of the mind"?
Psychology is a discipline that seeks to understand our "mind" and "behavior" properly, not just thinking vaguely, as if we were observing it in a laboratory. The "heart" here refers to our entire inner world, including our happy feelings, our sad feelings, our thoughts in our heads, and our unconscious thoughts that we feel at random moments. And "behavior" refers to the visible activities that we usually do, such as talking or walking. Psychology gently unravels the reasons why we feel the way we do and why we act the way we do.

There are two main paths to psychology. The first is the path of "basic psychology," which explores universal mental tendencies, as if unraveling the mechanism of the mind.
The other path is "applied psychology," which uses the knowledge of the mind to solve the worries and problems we face in our daily lives.
Basic psychology seeks to understand the mechanism of the mind from the ground up, while applied psychology seeks to use that knowledge to solve specific problems. Both are important signposts that will help us live better.
1.2 Basic Psychology – Let's Take a Look at the Mechanism of the Mind
Basic psychology is an adventure that explores the basic mechanisms of the mind. It's like finding the pieces of a puzzle one by one, unraveling the mechanisms of the mind.
- Physiological psychology (connection between mind and body) ・ We study how the mechanisms of the body, such as the brain, nerves, and hormones, affect our minds. It's as if you're peeking into the secrets of your mind from the inside of your body.
- Cognitive psychology (information processing of the mind) - We study the information processing process of the mind, how we understand, remember, think, and learn things. It's like magic that unravels the workings of the mind.
- Developmental psychology (the story of the growth of the mind) - We study how our minds and behaviors change from birth to adulthood. It's as if you're reliving the story of your heart's growth.
- Learning Psychology (Behavioral Change) - We study how our behavior changes through experience. It's like an adventure to explore the flexibility of the mind.
- Social psychology (the connection between the mind and society) - We study how people, society, and culture affect our minds. It's as if we understand the role of the mind in society.
1.3 Applied Psychology – The Magic of the Mind to Solve Life's Problems
Applied psychology is a field that uses the knowledge gained in basic psychology to solve problems in our lives, which is truly like the "magic of the mind."
- Clinical Psychology (Mental Care) ・ We help people who are traumatized or troubled to restore their mental health. It's like a gentle medicine that heals the pain in the heart.
- Educational Psychology (Learning Support) ・ We will explore how to make learning more fun and effective. It's like a guide who supports you on your learning journey.
- Industrial and Organizational Psychology (Mental Health of Workers) We will explore ways to improve the workplace environment and human relations so that workers can feel more comfortable and demonstrate their abilities. It's like magic that makes the workplace comfortable.
- Sports Psychology (Bringing Out the Power of the Mind): Unlocks the power of the mind of athletes and helps them perform at their best. It's like magic that boosts the energy of the mind.
- Disaster Psychology (Healing Emotional Wounds) ・ We take care of the minds of people who have suffered from disasters and accidents and help them heal their emotional wounds. It's like a compass to get you through the storm of your heart.
Chapter 2: The History of Psychology – A Journey in Search of the Mind
2.1 The Quest for the Heart, the Story of the Beginning
Psychology began as a scientific discipline in 1879. Wilhelm Wundt of Germany opened the world's first psychology laboratory. Until then, the mind had been thought of in the field of philosophy, but with the advent of Wundt, scientific exploration based on experiments and observations began. It's like the moment when a psychological adventure began.

Using a method called "introspection," Wundt asked people to put into words what was in their minds and searched for the basic elements of the mind. It was like putting the pieces of a mental puzzle together. This study was a major step forward in bringing psychology into the ranks of sciences.
2.2 The Quest for the Mind, Each Path
In response to Wundt's way of thinking, various schools of psychology were subsequently born. It's as if each of us is looking at our hearts through different lenses.
- Gestalt psychology (looking at the big picture) – is a way of thinking that values overall cohesion and patterns in perception and cognition. I tried to unravel the workings of the mind that tries to understand things as a whole, not just parts.
- Behaviorist psychology (focusing on behavior) - Objectively analyzed the relationship between stimuli and responses, focusing only on visible behaviors. It's an adventure that explores the secrets of the heart through visible actions.
- Psychoanalysis (exploring the unconscious) ・ I thought that the workings of the unconscious mind have a great influence on our behavior. Freud proposed that childhood experiences and suppressed feelings affect the mind. It's like an expedition searching for a treasure that lies deep in your heart.
2.3 Cognitive revolution and advances in modern psychology
In the 1950s, the "cognitive revolution" took place, and the information processing processes of the mind (perception, memory, thinking, etc.) became more important. It was as if the research was unraveling the information processing system of the mind. Modern psychology is trying to unravel the mechanisms of the mind in cooperation with various fields such as brain science, genetics, and information science. It's like a team play to solve the mystery of the mind.

3.2 Psychology of the Future – Convergence of Technology and Mind
Recently, advances in brain science have clarified the relationship between brain activity and the mind. It's as if the mechanism of the mind is being unraveled little by little. Technologies such as AI and VR are also beginning to be used in psychological research and treatment. It's as if the future of mental therapy is a warm hand in hand with technology and the heart.
3.3 The contemporary role of psychotherapy
Psychotherapy is an important activity to restore mental health. In modern society, there are many people who feel stressed and anxious. Psychotherapy plays an important role in healing the pain of such people's hearts. It's like a bandage that gently wraps around the wounds of your heart.
