The body and mind has multiple ways of responding to emotions. 

Emotions, aggression and stress in the brain

An emotion is a subjective state of being, often described as a feeling. It is typically an intense, affective state that occurs consciously and intentionally in response to a specific experience. Emotions arise from the interplay of four key components: a subjective experience, an outward expression, a cognitive appraisal of the situation, and physiological responses.

Subjects in emotions, aggression and stress in the brain

- Fear is one of Paul Ekman's 6 basic emotions that he believes are universal and genetically predisposed.
- Charles Darwin's theory of serviceable habits suggests that there is something adaptive in the form of the expression itself. Hence for example, the facial expression for fear is adaptive because you have to take as much information as possible to assess the environment and situation. 

Fear

Chronic pain is pain that is experienced for many days during a week for three months or more, and can either be a primary or secondary symptom. 

Chronic Pain

Cognitive reappraisal is an emotional regulation strategy that encourages the reinterpretation of an emotional stimulus in order to change the meaning of the stimulus.

Cognitive Reappraisal

The predictions of what emotions people think they will feel after making some decision. This affects the decision people make.

Expected emotions

Emotional response to the task at hand. This is usually in response to needs being met or ignored while interacting with the task. Responses to varying levels of emotional engagement can be:
- Happiness
- Anxiety
- Boredom

Emotional Engagement

“the outward expression of emotion, affect, and feeling by individuals and among individuals in a Community of Inquiry, as they relate to and interact with the learning technology, course content, learners, and the instructor”

Emotional Presence 

Emotions not caused by a decision. They are often associated with a person's predisposition, the setting of an environment or something that happened earlier in the day.

Incidental emotions

Focuses on the role of emotion in motivation, judgement, behavior, and health across the life span and across cultures. While predominantly studied in social psychology, related studies incorporate concepts and methods from other fields such as cognitive psychology and biology.

Studies on Emotion

Emotions are episodic and short term patterns of perceptions, communication, and action; these are responses (which are tied to biological and physiological aspects) that occur to perceived social and physical stressors.

What is an Emotion? ( deeper explanation)

Stress and anger negatively impact health, leading to higher risk of chronic diseases.

Emotion | Effect on Health

Functions of emotion for our survival pertain to: 
- Support adaptive action
- Regulate our pursuit of goals
- Promote selective responses
- Function of Facial Expressions

Functions of Emotions

- Basic Emotions
- Self-Conscious Emotions

Types of Emotions

Basic Emotions are innate bodily and neural states that are elicited by signal stimuli. Basic emotions come from a range of stimuli and are often associated with specific adaptive functions. 
There are 6 basic emotions: 
- Anger 
- Disgust
- Fear
- Sadness
- Joy
- Surprise 

Basic Emotions

Stages of emotion processing can occur in different orders and various steps can occur simultaneously. The stages of emotion processing include:
-  Appraisal: when a stimulus is deemed emotion-inflicting
-  Physical Response: changes in pulse, blood pressure, etc.
-  Facial expressions & nonverbal behavior: smiling, jumping, etc.
-  Motives: desire to spread one's emotion to others. 

Stages of Emotion Processing

Sources of emotions include:
-  Immediate Stimuli (someone does something that causes an emotional reaction)
-  Classically Conditioned (place or event is associated with a given emotion)
-  Memories/thoughts (emotions return when thinking about a particular event)

Sources of Emotions

Rather than focusing on the first emotion elicited by a message, the emotional flow hypothesis stresses the importance of the progression through multiple emotional states that a person experiences while interacting with a message.

Emotional Flow Hypothesis

The body maps show regions whose activation increased (warm colors) or decreased (cool colors) when the subject was feeling the indicated emotion.

Bodily Maps of Emotions

The feeling of psychological strain and uneasiness produced by situations of danger, threat, and loss of personal security or by internal conflicts, frustrations, loss of self-esteem, and grief. Also called emotional tension.

Emotional Stress

Emotion regulation is the process by which individuals manage their emotional responses to various situations and experiences. This involves altering their emotional experiences and how they are expressed.

Emotional granularity refers to the interoceptive resolution in perceiving internal emotional states and the capacity to transcribe them into descriptive and specified language.

Emotional Granularity / Emotion Differentiation

Emotion complexity represents a burgeoning sub-field within the study of emotion. It diverges from traditional views that categorize emotions discretely, instead emphasizing the intricate and multifaceted nature of emotional experiences.

Emotion Complexity

Meta-emotion lacks a unified definition, though it is commonly understood as one's feelings about experiencing specific emotions. However, broadly speaking, it encompasses an individual's awareness, knowledge, attitudes, and control regarding emotions.

Meta-Emotion / Metaemotion

Theories of emotions attempt to explain the origin and functions of affective states.
- Schachter-Singer Two-Factor Theory
- Evolutionary Theories
- Appraisal Theories
  * Cognitive-mediational theory
- Psychological Constructionism 
- Physiological Theories
  * James-Lange theory
  * Cannon-Bard theory

Emotional states are complex experiences that result from the combination of several key elements: physiological arousal, psychological appraisal, and subjective feelings. These elements, along with outward emotional expression, are collectively known as the components of emotion.

Components of Emotion

Which of the following best describes the concept of emotion?

Which of the following components are involved in the experience of emotion?

How does the specific stimulus experienced by an individual influence their emotion?

Which of the following statements accurately reflects the role of cognitive processes in emotion?

This area of study explores the physiological and neurological foundations of emotional experiences, examining the biological mechanisms that give rise to and regulate emotions.

Biological Underpinnings of Emotion

A mood is a prolonged, less intense affective state that, unlike an emotion, typically does not arise in response to a specific experience and lacks intentionality. In psychological research, a mood is considered an intangible variable or abstract construct; while it cannot be directly observed, researchers can measure it to evaluate its relationship with other phenomena, such as behavioral intentions.

Mood

Emotions and moods are distinct affective states that differ in several key aspects. Emotions are typically intense, brief, and are a direct response to a specific event or experience; they are also generally conscious and intentional. In contrast, moods are less intense, more prolonged states that are not linked to a specific trigger, may exist without conscious awareness, and lack intentionality.

Comparison of Emotion and Mood

The methodology for measuring emotions is a subject of debate within psychology. While researchers like Mauss have identified potential problems with how emotions are typically measured, they also contend that many of the commonly used measurements are still valuable and useful for understanding emotional processes.

Challenges in Measuring Emotion

Despite cultural display rules that dictate how emotions should be expressed, the fundamental ability to produce and recognize facial expressions of emotion is considered universal across all human cultures. This concept is supported by evidence from cross-cultural research, such as studies with isolated, preliterate societies, and the observation that congenitally blind individuals produce the same facial expressions as sighted people, suggesting these expressions are innate.
