- Pain is an unpleasant feeling often caused by intense or damaging stimuli, such as stubbing a toe, burning a finger, putting alcohol on a cut, and bumping the "funny bone."The International Association for the Study of Pain's widely used definition states, "Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage".
Pain motivates the individual to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future.  Most pain resolves promptly once the painful stimulus is removed and the body has healed, but sometimes pain persists despite removal of the stimulus and apparent healing of the body; and sometimes pain arises in the absence of any detectable stimulus, damage or disease.
Pain is the most common reason for physician consultation in the United States. It is a major symptom in many medical conditions, and can significantly interfere with a person's quality of life and general functioning. Psychological factors such as social support, hypnotic suggestion, excitement, or distraction can significantly modulate pain's intensity or unpleasantness.
- Fear is a distressing negative sensation induced by a perceived threat. It is a basic survival mechanism occurring in response to a specific stimulus, such as pain or the threat of danger. In short, fear is the ability to recognize danger leading to an urge to confront it or flee from it (also known as the fight-or-flight response) but in extreme cases of fear (terror) a freeze or paralysis response is possible. Some psychologists such as John B. Watson, Robert Plutchik, and Paul Ekman have suggested that fear belongs to a small set of basic or innate emotions. This set also includes such emotions as joy, sadness, and anger. Fear should be distinguished from the related emotional state of anxiety, which typically occurs without any certain or immediate external threat.
Additionally, fear is frequently related to the specific behaviors of escape and avoidance, whereas anxiety is the result of threats which are perceived to be uncontrollable or unavoidable. It is worth noting that fear almost always relates to future events, such as worsening of a situation, or continuation of a situation that is unacceptable. Fear can also be an instant reaction to something presently happening. All people have an instinctual response to potential danger. This emotion is described as fear and it is pre-programmed into all people. Fear, whatever its source, can become a controlling factor in a person’s life. Fear can channel one’s energies away from areas of perceived threats and into directions that seem safe.
- Regret is a negative conscious and emotional reaction to personal past acts and behaviors. Regret is often expressed by the term "sorry." Regret is often felt when someone feels sadness, shame, embarrassment, depression, annoyance or guilt after committing an action or actions that the person later wishes that s/he had not done or having not committed. Regret is distinct from guilt, which is a deeply emotional form of regret — one which may be difficult to comprehend in an objective or conceptual way. In this regard, the concept of regret is subordinate to guilt in terms of its emotional intensity. By comparison, shame typically refers to the social (rather than personal) aspect of guilt or (in minor context) regret as imposed by the society or culture (enforcement of ethics, morality), which has substantial bearing in matters of (personal and social) honor.
It is also distinct from remorse, which is a more direct and emotional form of regret over a past action that is considered by society to be hurtful, shameful, or violent. Unlike regret, it includes a strong element of desire for apology to others rather than an internal reflection on one's actions, and may be expressed (sincerely or not) in order to reduce the punishment one receives.
Regret can describe not only the dislike for an action that has been committed, but also, importantly, regret of inaction. Many people find themselves wishing that they had done something in a past situation.
- Desire is a sense of longing for a person or object or hoping for an outcome. Desire is the fire that sets action aflame. The same sense is expressed by emotions such as "craving" or "hankering". When a person desires something or someone, their sense of longing is excited by the enjoyment or the thought of the item or person, and they want to take actions to obtain their goal. The motivational aspect of desire has long been noted by philosophers; Hobbes (1588–1679) asserted that human desire is the fundamental motivation of all human action.
In Buddhism, for an individual to effect his or her liberation, the flow of sense-desire must be cut completely; however, while training, he or she must work with motivational processes based on skilfully applied desire. The Buddha stated, according to the early Buddhist scriptures, that monks should "generate desire" for the sake of fostering skillful qualities and abandoning unskillful ones.
While desires are often classified as emotions by laypersons, psychologists often describe desires as different from emotions; psychologists tend to argue that desires arise from bodily structures, such as the stomach's need for food, whereas emotions arise from a person's mental state. Marketing and advertising companies have used psychological research on how desire is stimulated to find more effective ways to induce consumers to buy a given product or service. While some advertising attempts to give buyers a sense of lack or wanting, other types of advertising create desire associating the product with desirable attributes, either by showing a celebrity or model with the product.
The theme of desire is at the core of the romance novel, which often create drama by showing cases where human desire is impeded by social conventions, class, or cultural barriers.
- Love is an emotion of strong affection and personal attachment. Love is also a virtue representing all of human kindness, compassion, and affection; and "the unselfish loyal and benevolent concern for the good of another". Love may also be described as actions towards others (or oneself) based on compassion, or as actions towards others based on affection.
In English, love refers to a variety of different feelings, states, and attitudes, ranging from pleasure ("I loved that meal") to interpersonal attraction ("I love my partner"). "Love" may refer specifically to the passionate desire and intimacy of romantic love, to the sexual love of eros, to the emotional closeness of familial love, or the platonic love that defines friendship, to the profound oneness or devotion of religious love. This diversity of uses and meanings, combined with the complexity of the feelings involved, makes love unusually difficult to consistently define, even compared to other emotional states.
Love in its various forms acts as a major facilitator of interpersonal relationships and, owing to its central psychological importance, is one of the most common themes in the creative arts.
Love may be understood as part of the survival instinct, a function to keep human beings together against menaces and to facilitate the continuation of the species. People with developmental disorders may have a limited or minimal capability of experiencing love.
