Emotions can be powerful expressions of your state of mind. Affect psychology is the study of how emotions and feelings are experienced, expressed, and regulated, and how they influence human behavior and mental processes. You might feel a wide variety of emotions consciously and unconsciously, and emotions might come and go, feeling fleeting or lasting for hours. The experiences that you have in your daily life may also affect your emotions, and your emotions may impact your relationships and interactions with others. Additionally, you might notice that you feel a certain level of control over your feelings at times and struggle to control them at others.

What is affect?

Affect is a psychological term used in a clinical sense to describe the experience of emotions. Affect display is a related term that refers to facial expressions, voice expressions, or gestures that indicate affect.

Modern psychology describes three affective domains including:

  • Affective
  • Behavioral
  • Cognitive

These domains are often referred to as the ABCs of psychology.

Are emotions and mood the same thing?

Individuals may use the words emotion and mood interchangeably. In the field of psychology, they have two different meanings. 

Emotion 

Emotion can be a subjective, affective state that projects a relatively intense physical or mental feeling. Often, emotions occur in response to an external or internal experience. We may experience emotions on a conscious level intentionally. For example, people may consciously choose to partake in behaviors that promote feelings of happiness, sadness, or other emotions. 

Mood 

Mood refers to a prolonged effective state that may be less intense than emotion. Moods might not surface in response to external or internal stimuli and are not intentional. Unless you're aware and in tune with yourself, you might not consciously recognize your moods. The main difference between the two is that moods last longer than emotions. 

Theories of emotion and affect in psychology

Research on the issue of emotions dates back to the 1800s with Charles Darwin's book The Expression Of The Emotions In Man And Animals. Affect and emotion are often complex areas of psychology, and researchers continue to learn more about them.

Evolutionary theory of emotion and affect

Charles Darwin was an early naturalist who suggested that emotions evolved because they were adaptive. Darwin philosophized that emotions allow humans and animals to survive and reproduce. For example, he felt that love and affection prompted people to look for and be attracted to mates so they could reproduce. He also suggested that fearful feelings caused people to react by fighting a source of danger or fleeing from it. 

Darwin's emotional theory of emotion indicated that humans might respond quickly to environmental stimuli to help us improve our chances of success and survival. If we encounter an animal hissing, barking, spitting, and clawing, we might notice that it could attack us, and we may back up or leave the area. The outward signs help us decide to leave the upset animal alone so that we might remain safe.

Cognitive appraisal theory or Lazarus’ theory of emotion in psychology

One of the early pioneers in emotional research was Richard Lazarus. Lazarus theorized that people might have a conscious thought before having an emotional or physiological response. He suggested a sequence of events that consists of a stimulus followed by a thought, which leads to one or more emotions.

For example, imagine it is late at night, and you have gone to bed. You hear a noise that sounds like a door opening, and you suddenly remember that you forgot to check all the doors to ensure they were locked before you went to bed. You might feel afraid that a stranger is entering your home. When you go to check the door, you notice it was your dog. In this scenario, a series of events led you to feel fear and ease after checking the door. 

The Cannon-Bird theory of emotion 

According to the Cannon-Bird theory of emotion, physiological responses and emotional experiences happen independently of one another simultaneously. For example, if you see a rabid dog running in your direction with teeth bared and a foaming mouth, the Cannon-Bird theory of emotion indicates that you might feel fear while your body goes into the fight or flight response. The emotion occurs separately but at the same time as a physiological reaction.

The James-Lange theory of emotion

The James-Lange theory of emotion may be similar to the Cannon-Bird theory, except that the James-Lange theory promotes the idea that emotions occur as a response to physiological arousal. Using the same example as above, the sight of the rabid dog racing directly towards you would signal immediate physiological arousal causing your heart to race and your breathing to speed up. The James-Lange theory asserts that feelings of fear and trepidation would only appear after the physiological response occurred. This theory may also suggest that different arousal patterns create different feelings.

The Schachter-Singer two-factor theory of emotion

The Schacter-Singer two-factor theory of emotion offers a slightly different thought process that includes emotion and physiological arousal. These researchers surmised that emotions are part physiological and part cognitive. According to this theory, physiological arousal occurs first. Our brains interpret it, and the emotion follows. In keeping with the example of the rabid dog, the sight of the dog might produce a sense of physiological arousal. The brain could interpret arousal as fear and produce the emotion of fear through this theory. 

The facial-feedback theory of emotion

The facial-feedback theory of emotion connects facial expressions to emotions, a concept that Charles Darwin and William James pointed to as a possibility. As the theory goes, physiological responses may sometimes impact emotion rather than be a result of the emotion. There is some consideration for the notion that emotions may be tied to changes in our facial muscles. 

If you force a smile at a meeting with a stranger, you may feel more inclined to carry on a discussion and get to know the person better. However, if you project a neutral facial expression, you may feel inclined to move along to someone more familiar.

What do we know about various types of emotions?

People can feel many emotions, sometimes on the same day. Our emotions may influence how we live and relate to others. During times of high emotion, we might feel our emotions control us. Our emotions can have a direct impact on how we make decisions and how we react and respond in various situations.

In addition to developing theories about how emotions present, researchers have also studied the different types of emotions people experience and created theories on how to explain them.

A psychologist named Paul Eckman labeled six basic emotions that he believed all human cultures experience universally. He identified the following emotions:

  1. Happiness
  2. Sadness
  3. Disgust
  4. Fear
  5. Surprise
  6. Anger

Later in his work, he revised his list to include pride, shame, embarrassment, and excitement.

Happiness

Of the six basic emotions, happiness is often considered a positive emotion. Throughout history, researchers have taken an interest in the discipline of positive psychology. Society and media may connect a state of happiness with attaining a particular lifestyle or acquiring material things. Regardless of what happiness means to someone, it may have a positive impact on health. 

Sadness

Sadness may be considered a transient emotion. Sad feelings may be characterized by disappointment, grief, hopelessness, disinterest, and a dampened mood. People could express their sadness through crying, acting dejected remaining quiet, withdrawing from others, or having a general lack of energy. Prolonged or severe periods of sadness may indicate depressive symptoms.

Fear

Fear is an emotion that may play a role in survival. Fear may invoke a fight, flight, or freeze response which can produce physiological arousal that helps people deal with real or perceived threats of harm. Fear is closely related to anxiety. Anxiety may be common in those who experience anxiety disorders.

Disgust

Disgust might be described as a repulsion to an appalling taste, sight, or smell. Some people may believe that disgust evolved as a reaction to harm. Disgust can be a reaction to a physical trigger such as poor hygiene, infection, or gruesome scenes. People might also experience disgust toward moral issues such as criminal behaviors, distasteful behavior, and immoral acts.  

Anger

Anger can be a powerful emotion characterized by hostility, agitation, frustration, or antagonism. Anger, like fear, can be part of a fight or flight reaction. Anger could be positive when it motivates someone to problem-solve but could cause problems if it motivates unhealthy behaviors. Often, psychologists consider anger a secondary emotion.

Surprise

Surprise may be a brief emotion. Feelings of surprise can emerge when a startling physiological response follows an unexpected event. Surprise can be positive, negative, or neutral.

Counseling to work through emotions 

Many people experience emotions. Understanding how to control behaviors motivated by emotions can be more complicated than labeling what you're feeling. In these cases, reaching out for support from a psychologist could be beneficial. 

Takeaway

If you face barriers to treatment, such as finances, distance, or availability, you can also reach out to a counselor online. Through online therapy, you may be able to utilize a matching system to be matched with a therapist who meets your preferences and specializes in your concerns. Additionally, studies show that online counseling can be more effective than traditional in-person counseling for many topics. One study found that 71% of the participants who utilized internet-based therapy found it preferable and more beneficial.
