Affective science is the scientific study of emotion or affect. This includes the study of emotion elicitation, emotional experience and the recognition of emotions in others. Of particular relevance are the nature of feeling, mood, emotionally-driven behaviour, decision-making, attention and self-regulation, as well as the underlying physiology and neuroscience of the emotions.
An increasing interest in emotion can be seen in the behavioral, biological and social sciences. Research over the last two decades suggests that many phenomena, ranging from individual cognitive processing to social and collective behavior, cannot be understood without taking into account affective determinants (i.e. motives, attitudes, moods, and emotions). [1] Just as the cognitive revolution of the 1960s spawned the cognitive sciences and linked the disciplines studying cognitive functioning from different vantage points, the emerging field of affective science seeks to bring together the disciplines which study the biological, psychological, and social dimensions of affect. In particular affective science includes psychology, affective neuroscience, sociology, psychiatry, anthropology, ethology, archaeology, economics, criminology, law, political science, history, geography, education and linguistics. Research is also informed by contemporary philosophical analysis and artistic explorations of emotions. Emotions developed in human history make organisms to react to environmental stimuli and challenges. [2]
The major challenge for this interdisciplinary domain is to integrate research focusing on the same phenomenon, emotion and similar affective processes, starting from different perspectives, theoretical backgrounds, and levels of analysis. As a result, one of the first challenges of affective science is to reach consensus on the definition of emotions. Discussion is ongoing as to whether emotions are primarily bodily responses or whether cognitive processing is central. Controversy also concerns the most effective ways to measure emotions and conceptualise how one emotion differs from another. Examples of this include the dimensional models of Russell and others, Plutchik's wheel of emotions, and the general distinction between basic and complex emotions.

Whether scientific method is at all suited for the study of the subjective aspect of emotion, feelings, is a question for philosophy of science and epistemology. In practice, the use of self-report (i.e. questionnaires) has been widely adopted by researchers. Additionally, web-based research is being used to conduct large-scale studies on the components of happiness for example. (www.authentichappiness.com is a website run by the University of Pennsylvania, where questionnaires are routinely taken by thousands of people all over the world based on a well-being criteria devised in the book 'Flourish.' by Martin Seligman. [3] ) Nevertheless, Seligman mentions in the book the poor reliability of using this method as it is often entirely subjective to how the individual is feeling at the time, as opposed to questionnaires which test for more long standing personal features that contribute to well-being such as meaning in life. Alongside this researchers also use functional magnetic resonance imaging, electroencephalography and physiological measures of skin conductance, muscle tension and hormone secretion. This hybrid approach should allow researchers to gradually pinpoint the affective phenomenon. There are also a few commercial systems available that claim to measure emotions, for instance using automated video analysis or skin conductance (affectiva).
A common way to measure the emotions of others is via their emotional expressions. These include facial expression, vocal expression and bodily posture. Much work has also gone into coding expressive behaviour computer programmes that can be used to read the subject's emotion more reliably. The model used for facial expression is the Facial Action Coding System or 'FACS'. An influential figure in the development of this system was Paul Ekman. For criticism, see the conceptual-act model of emotion.
These behavioural sources can be contrasted with language descriptive of emotions. In both respects one may observe the way that affective display differs from culture to culture.
The Stanford University Psychology Department has an Affective Science area. It emphasizes basic research on emotion, culture, and psychopathology using a broad range of experimental, psychophysiological, neural, and genetic methods to test theory about psychological mechanisms underlying human behavior. Topics include longevity, culture and emotion, reward processing, depression, social anxiety, risk for psychopathology, and emotion expression, suppression, and dysregulation. [4]
Emotions are physical and mental states brought on by neurophysiological changes, variously associated with thoughts, feelings, behavioral responses, and a degree of pleasure or displeasure. There is no scientific consensus on a definition. Emotions are often intertwined with mood, temperament, personality, disposition, or creativity.
Psychology is an academic and applied discipline involving the scientific study of human mental functions and behavior. Occasionally, in addition or opposition to employing the scientific method, it also relies on symbolic interpretation and critical analysis, although these traditions have tended to be less pronounced than in other social sciences, such as sociology. Psychologists study phenomena such as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Some, especially depth psychologists, also study the unconscious mind.
Empathy is generally described as the ability to take on another's perspective, to understand, feel, and possibly share and respond to their experience. There are more definitions of empathy that include but is not limited to social, cognitive, and emotional processes primarily concerned with understanding others. Often times, empathy is considered to be a broad term, and broken down into more specific concepts and types that include cognitive empathy, emotional empathy, somatic empathy, and spiritual empathy.
Sympathy is the perception of, understanding of, and reaction to the distress or need of another life form.
Affective neuroscience is the study of how the brain processes emotions. This field combines neuroscience with the psychological study of personality, emotion, and mood. The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
Emotional contagion is a form of social contagion that involves the spontaneous spread of emotions and related behaviors. Such emotional convergence can happen from one person to another, or in a larger group. Emotions can be shared across individuals in many ways, both implicitly or explicitly. For instance, conscious reasoning, analysis, and imagination have all been found to contribute to the phenomenon. The behaviour has been found in humans, other primates, dogs, and chickens.
Affect, in psychology, refers to the underlying experience of feeling, emotion, attachment, or mood. In psychology, "affect" refers to the experience of feeling or emotion. It encompasses a wide range of emotional states and can be positive or negative. Affect is a fundamental aspect of human experience and plays a central role in many psychological theories and studies. It can be understood as a combination of three components: emotion, mood, and affectivity. In psychology, the term "affect" is often used interchangeably with several related terms and concepts, though each term may have slightly different nuances. These terms encompass: emotion, feeling, mood, emotional state, sentiment, affective state, emotional response, affective reactivity, disposition. Researchers and psychologists may employ specific terms based on their focus and the context of their work.
Emotion is defined as any mental experience with high intensity and high hedonic content. The existence and nature of emotions in non-human animals are believed to be correlated with those of humans and to have evolved from the same mechanisms. Charles Darwin was one of the first scientists to write about the subject, and his observational approach has since developed into a more robust, hypothesis-driven, scientific approach. Cognitive bias tests and learned helplessness models have shown feelings of optimism and pessimism in a wide range of species, including rats, dogs, cats, rhesus macaques, sheep, chicks, starlings, pigs, and honeybees. Jaak Panksepp played a large role in the study of animal emotion, basing his research on the neurological aspect. Mentioning seven core emotional feelings reflected through a variety of neuro-dynamic limbic emotional action systems, including seeking, fear, rage, lust, care, panic and play. Through brain stimulation and pharmacological challenges, such emotional responses can be effectively monitored.
The facial feedback hypothesis, rooted in the conjectures of Charles Darwin and William James, is that one's facial expression directly affects their emotional experience. Specifically, physiological activation of the facial regions associated with certain emotions holds a direct effect on the elicitation of such emotional states, and the lack of or inhibition of facial activation will result in the suppression of corresponding emotional states.
According to some theories, emotions are universal phenomena, albeit affected by culture. Emotions are "internal phenomena that can, but do not always, make themselves observable through expression and behavior". While some emotions are universal and are experienced in similar ways as a reaction to similar events across all cultures, other emotions show considerable cultural differences in their antecedent events, the way they are experienced, the reactions they provoke and the way they are perceived by the surrounding society. According to other theories, termed social constructionist, emotions are more deeply culturally influenced. The components of emotions are universal, but the patterns are social constructions. Some also theorize that culture is affected by the emotions of the people.
Affect displays are the verbal and non-verbal displays of affect (emotion). These displays can be through facial expressions, gestures and body language, volume and tone of voice, laughing, crying, etc. Affect displays can be altered or faked so one may appear one way, when they feel another. Affect can be conscious or non-conscious and can be discreet or obvious. The display of positive emotions, such as smiling, laughing, etc., is termed "positive affect", while the displays of more negative emotions, such as crying and tense gestures, is respectively termed "negative affect".
Klaus Rainer Scherer is professor emeritus of psychology and director of the Swiss Center for Affective Sciences in Geneva. He is a specialist in the psychology of emotion. He is known for editing the Handbook of Affective Sciences and several other influential articles on emotions, expression, personality and music.
Emotional self-regulation or emotion regulation is the ability to respond to the ongoing demands of experience with the range of emotions in a manner that is socially tolerable and sufficiently flexible to permit spontaneous reactions as well as the ability to delay spontaneous reactions as needed. It can also be defined as extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. Emotional self-regulation belongs to the broader set of emotion regulation processes, which includes both the regulation of one's own feelings and the regulation of other people's feelings.
Paradoxical laughter is an exaggerated expression of humour which is unwarranted by external events. It may be uncontrollable laughter which may be recognised as inappropriate by the person involved. It is associated with mental illness, such as mania, hypomania or schizophrenia, schizotypal personality disorder and can have other causes. Paradoxical laughter is indicative of an unstable mood, often caused by the pseudobulbar affect, which can quickly change to anger and back again, on minor external cues.
Emotional responsivity is the ability to acknowledge an affective stimuli by exhibiting emotion. It is a sharp change of emotion according to a person's emotional state. Increased emotional responsivity refers to demonstrating more response to a stimulus. Reduced emotional responsivity refers to demonstrating less response to a stimulus. Any response exhibited after exposure to the stimulus, whether it is appropriate or not, would be considered as an emotional response. Although emotional responsivity applies to nonclinical populations, it is more typically associated with individuals with schizophrenia and autism.

Emotion perception refers to the capacities and abilities of recognizing and identifying emotions in others, in addition to biological and physiological processes involved. Emotions are typically viewed as having three components: subjective experience, physical changes, and cognitive appraisal; emotion perception is the ability to make accurate decisions about another's subjective experience by interpreting their physical changes through sensory systems responsible for converting these observed changes into mental representations. The ability to perceive emotion is believed to be both innate and subject to environmental influence and is also a critical component in social interactions. How emotion is experienced and interpreted depends on how it is perceived. Likewise, how emotion is perceived is dependent on past experiences and interpretations. Emotion can be accurately perceived in humans. Emotions can be perceived visually, audibly, through smell and also through bodily sensations and this process is believed to be different from the perception of non-emotional material.
Interpersonal emotion regulation is the process of changing the emotional experience of one's self or another person through social interaction. It encompasses both intrinsic emotion regulation, in which one attempts to alter their own feelings by recruiting social resources, as well as extrinsic emotion regulation, in which one deliberately attempts to alter the trajectory of other people's feelings.
Emotional intelligence (EI) involves using cognitive and emotional abilities to function in interpersonal relationships, social groups as well as manage one's emotional states. It consists of abilities such as social cognition, empathy and also reasoning about the emotions of others.
Emotions play a key role in overall mental health, and sleep plays a crucial role in maintaining the optimal homeostasis of emotional functioning. Deficient sleep, both in the form of sleep deprivation and restriction, adversely impacts emotion generation, emotion regulation, and emotional expression.
