Emotional Expression
An emotional expression is a behavior that communicates an emotional state or attitude. It can be verbal or nonverbal, and can occur with or without self-awareness. Emotional expressions include facial movements like smiling or scowling, simple behaviors like crying, laughing, or saying "thank you," and more complex behaviors like writing a letter or giving a gift. Individuals have some conscious control of their emotional expressions;Dorset Research & Development Support Unit, 2003"Emotional Expression." Retrieved on: July 23, 2007. however, they need not have conscious awareness of their emotional or affective state in order to express emotion. Researchers in psychology have proposed many different and often competing theoretical models to explain emotions and emotional expression, going as far back as Charles Darwin's discussion of emotion as an evolved capacity. Though there is no universally accepted theory of emotion, theorists in emotion agree that experience of emotion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonverbal Communication
Nonverbal communication (NVC) is the transmission of messages or signals through a nonverbal platform such as eye contact, facial expressions, gestures, posture, and body language. It includes the use of social cues, kinesics, distance ( proxemics) and physical environments/appearance, of voice ( paralanguage) and of touch ( haptics). A signal has three different parts to it, including the basic signal, what the signal is trying to convey, and how it is interpreted. These signals that are transmitted to the receiver depend highly on the knowledge and empathy that this individual has. It can also include the use of time ( chronemics) and eye contact and the actions of looking while talking and listening, frequency of glances, patterns of fixation, pupil dilation, and blink rate ( oculesics). The study of nonverbal communication started in 1872 with the publication of ''The Expression of the Emotions in Man and Animals'' by Charles Darwin. Darwin began to study nonverbal commu ...

Darwinism
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory, it originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance after Darwin published ''On the Origin of Species'' in 1859, including concepts which predated Darwin's theories. English biologist Thomas Henry Huxley coined the term ''Darwinism'' in April 1860. Terminology Darwinism subsequently referred to the specific concepts of natural selection, the Weismann barrier, or the central dogma of molecular biology. Though the term usually refers strictly to biological evolution, creationists have appropriated it to refer to the origin of life or to cosmic evolution, that ...

Cognitive Reappraisal
Cognitive appraisal (also called simply 'appraisal') is the subjective Interpretation (logic), interpretation made by an individual to Stimulus (physiology), stimuli in the environment. It is a component in a variety of theories relating to Psychological stress, stress, mental health, Coping (psychology), coping, and emotion. It is most notably used in the transactional model of stress and coping, introduced in a 1984 publication by Richard Lazarus and Susan Folkman. In this theory, cognitive appraisal is defined as the way in which an individual responds to and interprets stressors in life. A variety of mental disorders have been observed as having abnormal patterns of cognitive appraisal in those affected by the disorder. Other work has detailed how personality can influence the way in which individuals cognitively appraise a situation. The reframing of stimuli and experiences, called cognitive reappraisal, has been found "one of the most effective strategies for emotion regulation ...

Social Constructionism
Social constructionism is a theory in sociology, social ontology, and communication theory which proposes that certain ideas about physical reality arise from collaborative consensus, instead of pure observation of said reality. The theory centers on the notion that meanings are developed in coordination with others rather than separately by each individual. It has often been characterised as neo- Marxian or also as a neo- Kantian theory, in that social constructionism replaces the transcendental subject with a concept of society that is at the same time descriptive and normative. While some social constructs are obvious, for instance money or the concept of currency, in that people have agreed to give it importance/value, others are controversial and hotly debated, such as the concept of self/self-identity. This articulates the view that people in society construct ideas or concepts that may not exist without the existence of people or language to validate those concep ...

Western World
The Western world, also known as the West, primarily refers to the various nations and states in the regions of Europe, North America, and Oceania.Western Civilization Our Tradition; James Kurth; accessed 30 August 2011 The Western world is also known as the Occident (from the word ''occidēns'' "setting down, sunset, west") in contrast to the Eastern world known as the Orient (from the Latin word ''oriēns'' "origin, s ...

Executive Functions
In cognitive science and neuropsychology, executive functions (collectively referred to as executive function and cognitive control) are a set of cognitive processes that are necessary for the cognitive control of behavior: selecting and successfully monitoring behaviors that facilitate the attainment of chosen goals. Executive functions include basic cognitive processes such as attentional control, cognitive inhibition, inhibitory control, working memory, and cognitive flexibility. Higher-order executive functions require the simultaneous use of multiple basic executive functions and include planning and fluid intelligence (e.g., reasoning and problem-solving). Executive functions gradually develop and change across the lifespan of an individual and can be improved at any time over the course of a person's life. Similarly, these cognitive processes can be adversely affected by a variety of events which affect an individual. Both neuropsychological tests (e.g., the St ...

Affect (psychology)
Affect, in psychology, refers to the underlying experience of feeling, emotion or mood. History The modern conception of affect developed in the 19th century with Wilhelm Wundt. The word comes from the German ''Gefühl'', meaning "feeling." A number of experiments have been conducted in the study of social and psychological affective preferences (i.e., what people like or dislike). Specific research has been done on preferences, attitudes, impression formation, and decision-making. This research contrasts findings with recognition memory (old-new judgments), allowing researchers to demonstrate reliable distinctions between the two. Affect-based judgments and cognitive processes have been examined with noted differences indicated, and some argue affect and cognition are under the control of separate and partially independent systems that can influence each other in a variety of ways (Zajonc, 1980). Both affect and cognition may constitute independent sources of effects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antecedent (behavioral Psychology)
An antecedent is a stimulus that cues an organism to perform a learned behavior. When an organism perceives an antecedent stimulus, it behaves in a way that maximizes reinforcing consequences and minimizes punishing consequences. This might be part of complex, interpersonal communication. Antecedent stimuli (paired with reinforcing consequences) activate centers of the brain involved in motivation, while antecedent stimuli that have been paired with punishing consequences activate brain centers involved in fear. Antecedents play a different role while attempting to trigger positive and negative outcomes. There are some scientific papers that argue that there are two different types of antecedent variables. These two types of antecedent variables are referred to as discriminative stimuli and setting events. Setting events differ from discriminative stimuli as setting events are believed to have an effect on the stimulus-response relationship. It has been suggested that sett ...

Microexpression
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 s ...

Database
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facial Action Coding System
The Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö. It was later adopted by Paul Ekman and Wallace V. Friesen, and published in 1978. Ekman, Friesen, and Joseph C. Hager published a significant update to FACS in 2002. Movements of individual facial muscles are encoded by the FACS from slight different instant changes in facial appearance. It is a common standard to systematically categorize the physical expression of emotions, and it has proven useful to psychologists and to animators. Due to subjectivity and time consumption issues, the FACS has been established as a computed automated system that detects faces in videos, extracts the geometrical features of the faces, and then produces temporal profiles of each facial movement. Uses Using the FACS human coders can manually code nearly any anatomically possible facia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carroll Izard
Carroll Ellis Izard (October 8, 1923 – February 5, 2017) was an American research psychologist known for his contributions to differential emotions theory (DET), and the Maximally Discriminative Affect Coding System (MAX) on which he worked with Paul Ekman. Izard also undertook empirical studies into the facial feedback hypothesis according to which emotions which have different functions also cause facial expressions which in turn provide us with cues about what emotion a person is feeling. In addition, Izard constructed a multidimensional self-report measure – the '' Differential Emotions Scale'' – currently in its 4th edition (DES-IV). His later research focused on emotional development in young children and the development and testing of his Emotions Course for Young Children. Academic career Izard earned his PhD from Syracuse University in 1952 and served initially as a psychology professor at Vanderbilt University, where he carried out pioneering research into human ...
