Valence (psychology)
Valence, also known as hedonic tone, is a characteristic of emotions that determines their emotional affect (intrinsic appeal or repulsion). Positive valence corresponds to the "goodness" or attractiveness of an object, event, or situation, making it appealing or desirable. Conversely, negative valence relates to "badness" or averseness, rendering something unappealing or undesirable. This concept is not only used to describe the intrinsic qualities of objects and events but also categorizes emotions based on their inherent attractiveness or averseness. History The use of the term in psychology entered English with the translation from German ("Valenz") in 1935 of works of Kurt Lewin. The original German word suggests "binding", and is commonly used in a grammatical context to describe the ability of one word to semantically and syntactically link another, especially the ability of a verb to require a number of additional terms (e.g. subject and object) to form a complete ...

Affect (psychology)
Affect, in psychology, is the underlying experience of feeling, emotion, attachment theory, attachment, or Mood (psychology), mood. It encompasses a wide range of emotional states and can be positive (e.g., happiness, joy, excitement) or negative (e.g., sadness, anger, fear, disgust). 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 (enduring, less intense emotional states that are not necessarily tied to a specific event), and affectivity (an individual's overall disposition or temperament, which can be characterized as having a generally positive or negative affect). 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, a ...

Surprise (emotion)
Surprise () is a rapid, fleeting, mental and physiological state. It is related to the startle response experienced by animals and humans as the result of an unexpected event. Surprise can have any Valence (psychology), valence. That is, it can be pleasant/positive, unpleasant/negative, or neutral/moderate. Surprise can occur in varying levels of intensity ranging from very surprised, which may induce the fight-or-flight response, or slightly surprised, which elicits a less intense response to the stimulus. Surprise is included as a primary or basic emotion in the taxonomies of Carroll Izard and Paul Ekman. According to these perspectives, surprise is evolutionarily adaptive, and also innate and universal across human cultures. Causes Surprise is intimately connected to the idea of acting in accordance with a set of rules. When the rules of reality generating events of daily life separate from the rule-of-thumb expectations, surprise is the outcome. Surprise represents the ...

Feeling
According to the '' APA Dictionary of Psychology'', a feeling is "a self-contained phenomenal experience"; feelings are "subjective, evaluative, and independent of the sensations, thoughts, or images evoking them". The term ''feeling'' is closely related to, but not the same as, emotion. ''Feeling'' may, for instance, refer to the conscious subjective experience of emotions.VandenBos, Gary (2006) ''APA Dictionary of Psychology''. Washington, DC: American Psychological Association The study of subjective experiences is called ''phenomenology''. Psychotherapy generally involves a therapist helping a client understand, articulate, and learn to effectively regulate the client's own feelings, and ultimately to take responsibility for the client's experience of the world. Feelings are sometimes held to be characteristic of embodied consciousness. The English noun ''feelings'' may generally refer to any degree of subjectivity in perception or sensation. However, feelings often refer to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fear
Fear is an unpleasant emotion that arises in response to perception, perceived dangers or threats. Fear causes physiological and psychological changes. It may produce behavioral reactions such as mounting an aggressive response or fleeing the threat, commonly known as the fight-or-flight response. Extreme cases of fear can trigger an immobilized freeze response. Fear in humans can occur in response to a present stimulus (physiology), stimulus or anticipation of a future threat. Fear is involved in some mental disorders, particularly anxiety disorders. In humans and other animals, fear is modulated by cognition and learning. Thus, fear is judged as rational and appropriate, or irrational and inappropriate. Irrational fears are phobias. Fear is closely related to the emotion anxiety, which occurs as the result of often future threats that are perceived to be uncontrollable or unavoidable. The fear response serves survival and has been preserved throughout evolution. Even simple ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anger
Anger, also known as wrath ( ; ) or rage (emotion), rage, is an intense emotional state involving a strong, uncomfortable and non-cooperative response to a perceived provocation, hurt, or threat. A person experiencing anger will often experience physical effects, such as increased heart rate, elevated blood pressure, and increased levels of epinephrine, adrenaline and norepinephrine, noradrenaline. Some view anger as an emotion that triggers part of the fight-or-flight response, fight or flight response. Anger becomes the predominant feeling behavior, behaviorally, cognition, cognitively, and physiology, physiologically when a person makes the conscious choice to take action to immediately stop the threatening behavior of another outside force. Anger can have many physical and mental consequences. The external expression of anger can be found in facial expressions, body language, physiological responses, and at times public acts of aggression. Facial expressions can range from ...

Prefrontal Cortex
In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. It is the association cortex in the frontal lobe. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47. This brain region is involved in a wide range of higher-order cognitive functions, including speech formation (Broca's area), gaze ( frontal eye fields), working memory ( dorsolateral prefrontal cortex), and risk processing (e.g. ventromedial prefrontal cortex). The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals. Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex. This brain region has been implicated in executive functions, such as planning, decision making, working memory, personality expression, moderating ...

Superior Temporal Sulcus
The superior temporal sulcus (STS) is the sulcus separating the superior temporal gyrus from the middle temporal gyrus, in the temporal lobe of the mammalian brain. A sulcus (plural sulci) is a deep groove that curves into the largest part of the brain, the cerebrum, and a gyrus (plural gyri) is a ridge that curves outward of the cerebrum. The STS is located under the lateral fissure, which is the fissure that separates the temporal lobe, parietal lobe, and frontal lobe. The STS has an asymmetric structure between the left and right hemisphere, with the STS being longer in the left hemisphere, but deeper in the right hemisphere. This asymmetrical structural organization between hemispheres has only been found to occur in the STS of the human brain. The STS has been shown to produce strong responses when subjects perceive stimuli in research areas that include theory of mind, biological motion, faces, voices, and language.

Facial Expression
Facial expression is the motion and positioning of the muscles beneath the skin of the face. These movements convey the emotional state of an individual to observers and are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species. Humans can adopt a facial expression voluntarily or involuntarily, and the neural mechanisms responsible for controlling the expression differ in each case. Voluntary facial expressions are often socially conditioned and follow a cortical route in the brain. Conversely, involuntary facial expressions are believed to be innate and follow a subcortical route in the brain. Facial recognition can be an emotional experience for the brain and the amygdala is highly involved in the recognition process. Beyond the accessory nature of facial expressions in spoken communication between people, they play a significant role in communication ...

Brain Imaging
Neuroimaging is the use of quantitative (computational) techniques to study the structure and function of the central nervous system, developed as an objective way of scientifically studying the healthy human brain in a non-invasive manner. Increasingly it is also being used for quantitative research studies of brain disease and psychiatric illness. Neuroimaging is highly multidisciplinary involving neuroscience, computer science, psychology and statistics, and is not a medical specialty. Neuroimaging is sometimes confused with neuroradiology. Neuroradiology is a medical specialty that uses non-statistical brain imaging in a clinical setting, practiced by radiologists who are medical practitioners. Neuroradiology primarily focuses on recognizing brain lesions, such as vascular diseases, strokes, tumors, and inflammatory diseases. In contrast to neuroimaging, neuroradiology is qualitative (based on subjective impressions and extensive clinical training) but sometimes uses basic q ...

Facial Electromyography
Facial electromyography (fEMG) refers to an electromyography (EMG) technique that measures muscle activity by detecting and amplifying the tiny electrical impulses that are generated by muscle fibers when they contract. It primarily focuses on two major muscle groups in the face, the corrugator supercilii group which is associated with frowning and the zygomaticus major muscle group which is associated with smiling. Uses Facial EMG has been studied to assess its utility as a tool for measuring emotional reaction. Studies have found that activity of the corrugator muscle, which lowers the eyebrow and is involved in producing frowns, varies inversely with the emotional valence of presented stimuli and reports of mood state. Activity of the zygomatic major muscle, which controls smiling, is said to be positively associated with positive emotional stimuli and positive mood state. Facial EMG has been used as a technique to distinguish and track positive and negative emotional rea ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Paul Ekman
Paul Ekman (born February 15, 1934) is an American psychologist and professor emeritus at the University of California, San Francisco who is a pioneer in the study of emotions and their relation to facial expressions. He was ranked 59th out of the 100 most eminent psychologists of the twentieth century in 2002 by the ''Review of General Psychology''. His empirical and theoretical work helped to restart the study of emotion and non-verbal communication in the field of psychology, and introduced new quantitative frameworks which researchers could use to do so. He also carried out important early work on the physiology of emotions. Biography Childhood Paul Ekman was born in 1934 in Washington, D.C., and grew up in a Jewish family in New Jersey, Washington, Oregon, and California. His father was a pediatrician and his mother was an attorney. His sister, Joyce Steinhart, is a psychoanalytic psychologist who, before her retirement, practiced in New York City.

Microexpressions
A microexpression is a facial expression that only lasts for a short moment. It is the innate result of a voluntary and an involuntary emotional response occurring simultaneously and conflicting with one another, and occurs when the amygdala responds appropriately to the stimuli that the individual experiences and the individual wishes to conceal this specific emotion. This results in the individual very briefly displaying their true emotions followed by a false emotional reaction. Human emotions are an unconscious biopsychosocial reaction that derives from the amygdala and they typically last 0.5–4.0 seconds, although a microexpression will typically last less than 1/2 of a second. Unlike regular facial expressions it is either very difficult or virtually impossible to hide microexpression reactions. Microexpressions cannot be controlled as they happen in a fraction of a second, but it is possible to capture someone's expressions with a high speed camera and replay them at much ...
