Emotion

You have many feelings.

These feelings happen in your mind and body. They can be big or small. Some feelings last a long time. Others happen very fast.

Your body changes when you feel things. You might change your face or your voice. This helps show others how you feel. People around the world feel many of the same things. It is a special part of being human.

What are emotions? They are ways our minds and bodies react to the world.

Emotions can be big or small. Some feelings last a long time. Others happen very fast.

Emotions have many parts. One part is how we think about a situation. This is called cognitive appraisal. Another part is how our bodies change. For example, your heart might beat fast. You might also change your face or voice. This helps show others how you feel.

Some scientists study basic emotions. Paul Ekman found that some emotions are the same for everyone. He studied six basic ones: anger, disgust, fear, happiness, sadness, and surprise. Other researchers found even more. They found feelings like awe, pride, and shame.

Robert Plutchik made a special tool. He called it the wheel of emotions.

He thought some emotions could blend together. Just like colors, they can make new feelings. This helps us understand the many ways we feel every day.

Emotions are the ways our minds and bodies react to the world. They are physical and mental states caused by changes in our bodies. These changes happen because of our thoughts and feelings. They can bring us pleasure or displeasure. Emotions are often linked to our moods and our personalities. They can even be linked to how creative we are. Scientists study emotions to understand how they work in our daily lives.

An emotion is not just one thing. It is a group of many parts working together. One part is cognitive appraisal, which means how we judge what is happening. Another part is bodily symptoms, like your heart beating faster. We also have action tendencies, which prepare our bodies to move. Our faces and voices change to show others our feelings. This is called expression. Finally, we have the subjective feeling, which is the private experience in our own minds.

People have wondered about emotions for a very long time. Famous thinkers like Aristotle and Plato studied them. In 1773, David Hume wrote about how fears and desires move us to act. He believed reason follows our passions. The word emotion comes from the French word "émotion." This word means "to stir up." In the early 1800s, Thomas Brown used the word in academic talks. By the 1830s, the modern idea of emotion became common in English.

Many scientists have tried to group emotions into lists. Paul Ekman studied six basic emotions: anger, disgust, fear, happiness, sadness, and surprise. He found these are recognized by people in many different cultures. Later, researchers found even more, like awe, pride, and shame. Robert Plutchik created a "wheel of emotions" to show how they work. He thought primary emotions could blend together like colors. For example, anger and disgust might blend to form contempt.

It is helpful to know how emotions differ from other feelings. A mood is a state that lasts longer but is less intense. An emotion is often a quick reaction to a specific event. Some people have a disposition, which is a personality trait. This means they might feel certain emotions more easily than others. Some people even have alexithymia, which is when they cannot express or perceive emotions well. Understanding these differences helps us see how complex our inner lives are.

Emotions are complex physical and mental states. They are triggered by neurophysiological changes in the body. These changes are often linked to thoughts, feelings, and behavioral responses. An emotion can result in a sense of pleasure or displeasure. While there is no single scientific consensus on a definition, emotions are closely tied to mood, temperament, and personality. They can even influence a person's creativity. Today, many different fields study them. These include psychology, medicine, history, sociology, computer science, and philosophy.

To understand how an emotion happens, we can look at the Component Process Model (CPM). This model suggests that an emotional episode requires several parts to work together. First, there is cognitive appraisal. This is the process where a person evaluates an event or an object. This evaluation then triggers bodily symptoms, which are the physical changes in the body. Next, action tendencies develop. These are motivations that prepare the body for specific movements. Almost always, expression occurs through facial and vocal changes to communicate with others. Finally, the person has a feeling, which is the private, subjective experience of the emotion.

Scientists categorize emotions in different ways depending on their discipline. In psychology and philosophy, an emotion is usually seen as a conscious experience. This experience includes biological reactions and mental states. Sociologists like Peggy Thoits have described emotions as involving cultural labels, such as "anger" or "surprise." These labels help people understand their own physiological components and body actions. Some researchers also study emotion dynamics. This means they look at how the intensity and stability of emotions change in daily life. They also study how different emotions might augment or blunt one another over time.

Humanity has studied the mind and bodily sensations for a very long time. Many Western philosophers, including Aristotle, Plato, and Descartes, proposed theories about what motivates human action. During the Age of Enlightenment, the Scottish thinker David Hume offered a famous perspective. In his 1773 book, *A Treatise of Human Nature*, he argued that passions drive human conduct. Hume suggested that reason is often the "slave" of the passions. This means that our desires and experiences often direct our actions more than pure logic does. The word "emotion" itself comes from the French word *émotion*, meaning "to stir up." The modern concept of emotion emerged in the English language around the 1830s.

Researchers have tried to classify emotions into specific groups. For over 40 years, Paul Ekman has argued that certain emotions are universal. His research identified six basic emotions: anger, disgust, fear, happiness, sadness, and surprise. He found that these are recognized across many different cultures. Later, researchers Daniel Cordaro and Dacher Keltner expanded this list. They found evidence for emotions like awe, contentment, and sympathy. Robert Plutchik took a different approach with his "wheel of emotions." He proposed eight primary emotions, such as joy versus sadness or trust versus disgust. He suggested that these primary emotions can blend together like colors to create complex emotions.

It is important to distinguish emotions from other mental states. An emotion is often a rapid response to a specific stimulus. In contrast, a mood is an enduring state that is less intense. Moods often lack a specific context or trigger. There is also the concept of an emotional disposition. This is a character trait where a person is more likely to feel certain emotions quickly. For example, an irritable person has a disposition toward irritation. Some people may also experience alexithymia. This is a term used in psychiatry for the inability to perceive or express emotions.

Emotions are deeply connected to the broader study of human biology and society. Modern research uses advanced tools like PET and fMRI scans. These tools allow neuroscientists to study the affective processes happening in the brain. By looking at these physical processes, scientists can better understand the link between the mind and the body. This research helps us understand how emotions affect our well-being throughout our entire lifespan. Understanding these systems helps us see how our internal states interact with the external world.
