Smile
A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a Duchenne smile. Among humans, a smile expresses delight, sociability, happiness, joy, or amusement. It is distinct from a similar but usually involuntary expression of anxiety known as a grimace. Although cross-cultural studies have shown that smiling is a means of communication throughout the world, there are large differences among different cultures, religions, and societies, with some using smiles to convey confusion or embarrassment. Evolutionary background Primatologist Signe Preuschoft traces the smile back over 30 million years of evolution to a "fear grin" stemming from monkeys and apes, who often used barely clenched teeth to portray to predators that they were harmless or to signal submission to more dominant group members. The smile may have evolved differently among s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimple
A dimple, also called a gelasin (, ) is a small natural indentation in the flesh on a part of the human body, most notably in the cheek. Numerous cultures believe that cheek dimples are a good luck charm that entices people who perceive them as physically attractive, but they are also associated with heroism and innocence, which has been included in literature for many centuries. Medical research debates whether cheek dimples can be inherited or which type of allele they are, but it is certain that humans with cheek dimples are more likely to have them in both cheeks. Depth and length appearances are affected by the shape of the skull and dimples can appear and disappear due to age. There are four types of facial dimples, including cheek, and the cleft chin (sometimes nicknamed a "chin dimple"). Overview Cheek dimples when present, show up when a person makes a facial expression, such as smiling, whereas a chin dimple is a small line on the chin that stays on the chin without ...

Mona Lisa
The ''Mona Lisa'' ( ; it, Gioconda or ; french: Joconde ) is a half-length portrait painting by Italian artist Leonardo da Vinci. Considered an archetypal masterpiece of the Italian Renaissance, it has been described as "the best known, the most visited, the most written about, the most sung about, the most parodied work of art in the world". The painting's novel qualities include the subject's enigmatic expression, the monumentality of the composition, the subtle modelling of forms, and the atmospheric illusionism. The painting has been definitively identified to depict Italian noblewoman Lisa Gherardini, the wife of Francesco del Giocondo. It is painted in oil on a white Lombardy poplar panel. Leonardo never gave the painting to the Giocondo family, and later it is believed he left it in his will to his favored apprentice Salaì. It had been believed to have been painted between 1503 and 1506; however, Leonardo may have continued working on it as late as 1517. It ...

Positive Reinforcement
In behavioral psychology, reinforcement is a consequence applied that will strengthen an organism's future behavior whenever that behavior is preceded by a specific antecedent stimulus. This strengthening effect may be measured as a higher frequency of behavior (e.g., pulling a lever more frequently), longer duration (e.g., pulling a lever for longer periods of time), greater magnitude (e.g., pulling a lever with greater force), or shorter latency (e.g., pulling a lever more quickly following the antecedent stimulus). The model of self-regulation has three main aspects of human behavior, which are self-awareness, self-reflection, and self-regulation. Reinforcements traditionally align with self-regulation. The behavior can be influenced by the consequence but behavior also needs antecedents. There are four types of reinforcement: positive reinforcement, negative reinforcement, extinction, and punishment. Positive reinforcement is the application of a positive reinforcer. Nega ...

Laughter
Laughter is a pleasant physical reaction and emotion consisting usually of rhythmical, often audible contractions of the diaphragm and other parts of the respiratory system. It is a response to certain external or internal stimuli. Laughter can rise from such activities as being tickled, or from humorous stories or thoughts. Most commonly, it is considered an auditory expression of a number of positive emotional states, such as joy, mirth, happiness, or relief. On some occasions, however, it may be caused by contrary emotional states such as embarrassment, surprise, or confusion such as nervous laughter or courtesy laugh. Age, gender, education, language, and culture are all indicators as to whether a person will experience laughter in a given situation. Some other species of primate (chimpanzees, gorillas and orangutans) show laughter-like vocalizations in response to physical contact such as wrestling, play chasing or tickling. Laughter is a part of human behavior regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zygomaticus Major Muscle
The zygomaticus major muscle is a muscle of the human body. It extends from each zygomatic arch (cheekbone) to the corners of the mouth. It is a muscle of facial expression which draws the angle of the mouth superiorly and posteriorly to allow one to smile. Bifid zygomaticus major muscle is a notable variant, and may cause cheek dimples. Structure The zygomaticus major muscle originates from the upper margin of the temporal process, part of the lateral surface of the zygomatic bone. It inserts into tissue at the corner of the mouth. Nerve supply The zygomaticus major muscle is supplied by a buccal branch and a zygomatic branch of the facial nerve (VII). Variation The zygomaticus major muscle may occur in a bifid form, with two fascicles that are partially or completely separate from each other but adjacent. Usually a single unit, dimples are caused by variations in form. It is thought that cheek dimples are caused by bifid zygomaticus major muscle. Function The zygo ...

Psychological Manipulation
Manipulation in psychology is a behavior designed to exploit, control, or otherwise influence others to one’s advantage. Definitions for the term vary in which behavior is specifically included, influenced by both culture and whether referring to the general population or used in clinical contexts. Manipulation is generally considered a dishonest form of social influence as it is used at the expense of others. Manipulative tendencies may derive from personality disorders such as borderline personality disorder, narcissistic personality disorder, or antisocial personality disorder. Manipulation is also correlated with higher levels of emotional intelligence, and is a chief component of the personality construct dubbed Machiavellianism. Manipulation differs from general influence and persuasion. Influence is generally perceived to be harmless and it is not seen as unduly coercive to the individual's right of acceptance or rejection of influence. Persuasion is the ability to mov ...

Human Mouth
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, in humans the mouth also plays a significant role in communication. While primary aspects of the voice are produced in the throat, the tongue, lips, and jaw are also needed to produce the range of sounds included in speech. The mouth consists of two regions, the vestibule and the oral cavity proper. The mouth, normally moist, is lined with a mucous membrane, and contains the teeth. The lips mark the transition from mucous membrane to skin, which covers most of the body. Structure Oral cavity The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral cavity is bounded at the sides and in front by the alveolar proc ...

Amusement
Amusement is the state of experiencing humorous and entertaining events or situations while the person or animal actively maintains the experience, and is associated with enjoyment, happiness, laughter and pleasure. It is an emotion with positive valence and high physiological arousal. Amusement is considered an "epistemological" emotion because humor occurs when one experiences a cognitive shift from one knowledge structure about a target to another, such as hearing the punchline of a joke. The pleasant surprise that happens from learning this new information leads to a state of amusement which people often express through smiling, laughter or chuckling. Current studies have not yet reached consensus on the exact purpose of amusement, though theories have been advanced in the fields of psychology, psychiatry, and sociology. In addition, the precise mechanism that causes a given element (image, sound, behavior, etc.) to be perceived as more or less 'amusing' than another si ...

Human
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus '' Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Ana ...

Élisabeth Vigée Le Brun
Élisabeth Louise Vigée Le Brun (; 16 April 1755 – 30 March 1842), also known as Madame Le Brun, was a French portrait painter, especially of women, in the late 18th and early 19th centuries. Her artistic style is generally considered part of the aftermath of Rococo with elements of an adopted Neoclassical style. Her subject matter and color palette can be classified as Rococo, but her style is aligned with the emergence of Neoclassicism. Vigée Le Brun created a name for herself in Ancien Régime society by serving as the portrait painter to Marie Antoinette. She enjoyed the patronage of European aristocrats, actors, and writers, and was elected to art academies in ten cities. Vigée Le Brun created 660 portraits and 200 landscapes. In addition to many works in private collections, her paintings are owned by major museums, such as the Louvre Paris, Uffizi Florence, Hermitage Museum Saint Petersburg, National Gallery in London, Metropolitan Museum of Art in New York and man ...

Dishonesty
Dishonesty is to act without honesty. It is used to describe a lack of probity, cheating, lying, or deliberately withholding information, or being deliberately deceptive or a lack in integrity, knavishness, perfidiosity, corruption or treacherousness. Dishonesty is the fundamental component of a majority of offences relating to the acquisition, conversion and disposal of property (tangible or intangible) defined in criminal law such as fraud. English law Dishonesty has had a number of definitions. For many years, there were two views of what constituted dishonesty in English law. The first contention was that the definitions of dishonesty (such as those within the Theft Act 1968) described a course of action, whereas the second contention was that the definition described a state of mind. A clear test within the criminal law emerged from '' R v Ghosh'' (1982) 75 CR App. R. 154. The Court of Appeal held that dishonesty is an element of '' mens rea'', clearly referring to a s ...
