Emotions are 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.
Humour or humor is the tendency of experiences to provoke laughter and provide amusement. The term derives from the humoral medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as humours, controlled human health and emotion.
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.
Self-perception theory (SPT) is an account of attitude formation developed by psychologist Daryl Bem. It asserts that people develop their attitudes by observing their own behavior and concluding what attitudes must have caused it. The theory is counterintuitive in nature, as the conventional wisdom is that attitudes determine behaviors. Furthermore, the theory suggests that people induce attitudes without accessing internal cognition and mood states. The person interprets their own overt behaviors rationally in the same way they attempt to explain others' behaviors.
In psychoanalytic theory, a defence mechanism is an unconscious psychological operation that functions to protect a person from anxiety-producing thoughts and feelings related to internal conflicts and outer stressors.
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and reactivity.
The Yerkes–Dodson law is an empirical relationship between pressure and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases. The process is often illustrated graphically as a bell-shaped curve which increases and then decreases with higher levels of arousal. The original paper was only referenced ten times over the next half century, yet in four of the citing articles, these findings were described as a psychological "law".
Curiosity is a quality related to inquisitive thinking such as exploration, investigation, and learning, evident in humans and animals. Curiosity is associated with all aspects of human development, from which derives the process of learning and desire to acquire knowledge and skill.
The two-factor theory of emotion states that emotion is based on two factors: physiological arousal and cognitive label. The theory was created by researchers Stanley Schachter and Jerome E. Singer. According to the theory, when an emotion is felt, a physiological arousal occurs and the person uses the immediate environment to search for emotional cues to label the physiological arousal. This can sometimes cause misinterpretations of emotions based on the body's physiological state. When the brain does not know why it feels an emotion it relies on external stimulation for cues on how to label the emotion.
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.
Appraisal theory is the theory in psychology that emotions are extracted from our evaluations of events that cause specific reactions in different people. Essentially, our appraisal of a situation causes an emotional, or affective, response that is going to be based on that appraisal. An example of this is going on a first date. If the date is perceived as positive, one might feel happiness, joy, giddiness, excitement, and/or anticipation, because they have appraised this event as one that could have positive long-term effects, i.e. starting a new relationship, engagement, or even marriage. On the other hand, if the date is perceived negatively, then our emotions, as a result, might include dejection, sadness, emptiness, or fear. Reasoning and understanding of one's emotional reaction becomes important for future appraisals as well. The important aspect of the appraisal theory is that it accounts for individual variability in emotional reactions to the same event.
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.
The broaden-and-build theory in positive psychology suggests that positive emotions broaden one's awareness and encourage novel, exploratory thoughts and actions. Over time, this broadened behavioral repertoire builds useful skills and psychological resources. The theory was developed by Barbara Fredrickson around 1998.
Emotion classification, the means by which one may distinguish or contrast one emotion from another, is a contested issue in emotion research and in affective science. Researchers have approached the classification of emotions from one of two fundamental viewpoints:
- that emotions are discrete and fundamentally different constructs
- that emotions can be characterized on a dimensional basis in groupings
Negative affectivity (NA), or negative affect, is a personality variable that involves the experience of negative emotions and poor self-concept. Negative affectivity subsumes a variety of negative emotions, including anger, contempt, disgust, guilt, fear, and nervousness. Low negative affectivity is characterized by frequent states of calmness and serenity, along with states of confidence, activeness, and great enthusiasm.
The self-discrepancy theory states that individuals compare their "actual" self to internalized standards or the "ideal/ought self". Inconsistencies between "actual", "ideal" and "ought" are associated with emotional discomforts. Self-discrepancy is the gap between two of these self-representations that leads to negative emotions.
Sport psychology was defined by the European Federation of Sport Psychology (FEPSAC) in 1996, as the study of the psychological basis, processes, and effects of sport. Otherwise, sport is considered as any physical activity where the individuals engage for competition and health. Sport psychology is recognized as an interdisciplinary science that draws on knowledge from many related fields including biomechanics, physiology, kinesiology and psychology. It involves the study of how psychological factors affect performance and how participation in sport and exercise affect psychological and physical factors. Sport psychologists teach cognitive and behavioral strategies to athletes in order to improve their experience and performance in sports.
Clutch performance in sports refers to the phenomenon where athletes excel under pressure, commonly known as "in the clutch". These moments can occur at any point during the game, and involve plays that significantly impact the outcome of the game. Athletes are required to summon strength, concentration and any other qualities necessary to succeed and perform well. This phenomenon is observed in many sports including basketball, hockey, football, and esports, but the phrase is most commonly used in baseball.
The Differential Emotions Scale (DES) is a multidimensional self-report device for assessment of an individual's emotions. The DES helps measure mood based on Carroll Izard's differential emotions theory, The DES consists of thirty items, three for each of the ten fundamental emotions as visualized by Izard: interest, joy, surprise, sadness, anger, disgust, contempt, fear, shame/ shyness, and guilt, which are represented on 5-point Likert scale. There are currently four different versions of the scale. Despite the different versions, the basic idea of are very similar. Participants are asked to rate each of the emotions on a scale, and depending on the instructions given, they either rate their current feelings, feelings over the past week, or over long-term traits. The DES is similar to other scales such as the Multiple Affect Adjective Check List (MAACL) and the Multiple Affect Adjective Check List-Revised (MAACL-R) which are used to assess either the state or trait affect by varying the time of which instructions are given to the participants.
