Color or colour is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra and interference. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelength, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain.
Aggression is a behavior aimed at opposing or attacking something or someone. Though often done with the intent to cause harm, it can be channeled into creative and practical outlets for some. It may occur either reactively or without provocation. In humans, aggression can be caused by various triggers. For example, built-up frustration due to blocked goals or perceived disrespect. Human aggression can be classified into direct and indirect aggression; whilst the former is characterized by physical or verbal behavior intended to cause harm to someone, the latter is characterized by behavior intended to harm the social relations of an individual or group.
Color theory, or more specifically traditional color theory, is the historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. Modern color theory is generally referred to as Color science. While there is no clear distinction in scope, traditional color theory tends to be more subjective and have artistic applications, while color science tends to be more objective and have functional applications, such as in chemistry, astronomy or color reproduction. Color theory dates back at least as far as Aristotle's treatise On Colors. A formalization of "color theory" began in the 18th century, initially within a partisan controversy over Isaac Newton's theory of color and the nature of primary colors. By the end of the 19th century, a schism had formed between traditional color theory and color science.
The McCollough effect is a phenomenon of human visual perception in which colorless gratings appear colored contingent on the orientation of the gratings. It is an aftereffect requiring a period of induction to produce it. For example, if someone alternately looks at a red horizontal grating and a green vertical grating for a few minutes, a black-and-white horizontal grating will then look greenish and a black-and-white vertical grating will then look pinkish. The effect is remarkable because, although it diminishes rapidly with repeated testing, it has been reported to last up to 2.8 months when exposure to testing is limited.
Abram Hoffer was a Canadian biochemist, physician, and psychiatrist known for his "adrenochrome hypothesis" of schizoaffective disorders. According to Hoffer, megavitamin therapy and other nutritional interventions are potentially effective treatments for cancer and schizophrenia. Hoffer was also involved in studies of LSD as an experimental therapy for alcoholism and the discovery that high-dose niacin can be used to treat high cholesterol and other dyslipidemias. Hoffer's ideas about megavitamin therapy to treat mental illness are not accepted by the medical community.
The studies of violence in radio analyzes the degree of correlation between themes of violence in media sources with real-world aggression and violence over time. Many social scientists support the correlation, however, some scholars argue that media research has methodological problems and that findings are exaggerated. Other scholars have suggested that the correlation exists, but can be unconventional to the current public belief.
Alcohol myopia is a cognitive-physiological theory on alcohol use disorder in which many of alcohol's social and stress-reducing effects, which may underlie its addictive capacity, are explained as a consequence of alcohol's narrowing of perceptual and cognitive functioning. The alcohol myopia model posits that rather than disinhibit, alcohol produces a myopia effect that causes users to pay more attention to salient environmental cues and less attention to less salient cues. Therefore, alcohol's myopic effects cause intoxicated people to respond almost exclusively to their immediate environment. This "nearsightedness" limits their ability to consider future consequences of their actions as well as regulate their reactive impulses.
Pink colors are usually light or desaturated shades of reds, roses, and magentas which are created on computer and television screens using the RGB color model and in printing with the CMYK color model. As such, it is an arbitrary classification of color.
Color symbolism in art, literature, and anthropology refers to the use of color as a symbol in various cultures and in storytelling. There is great diversity in the use of colors and their associations between cultures and even within the same culture in different time periods. The same color may have very different associations within the same culture at any time. Diversity in color symbolism occurs because color meanings and symbolism occur on an individual, cultural and universal basis. Color symbolism is also context-dependent and influenced by changes over time. Symbolic representations of religious concepts or articles may include a specific color with which the concept or object is associated.
Color psychology is the study of hues as a determinant of human behavior. Color influences perceptions that are not obvious, such as the taste of food. Colors have qualities that can cause certain emotions in people. How color influences individuals may differ depending on age, gender, and culture. Although color associations can vary contextually between cultures, color preference is thought to be relatively uniform across gender and race.
Biosocial criminology is an interdisciplinary field that aims to explain crime and antisocial behavior by exploring biocultural factors. While contemporary criminology has been dominated by sociological theories, biosocial criminology also recognizes the potential contributions of fields such as behavioral genetics, neuropsychology, and evolutionary psychology.
Cartoon violence is the representation of violent actions involving animated characters and situations. This may include violence where a character is unharmed after the action has been inflicted. Animated violence is sometimes partitioned into comedic and non-comedic cartoon violence. Popular television programs with cartoon violence include Rick and Morty, Tom and Jerry, Looney Tunes, The Simpsons, and Family Guy.
In the psychology of color, color preferences are the tendency for an individual or a group to prefer some colors over others, such as having a favorite color or a traditional color.
Image editing encompasses the processes of altering images, whether they are digital photographs, traditional photo-chemical photographs, or illustrations. Traditional analog image editing is known as photo retouching, using tools such as an airbrush to modify photographs or editing illustrations with any traditional art medium. Graphic software programs, which can be broadly grouped into vector graphics editors, raster graphics editors, and 3D modelers, are the primary tools with which a user may manipulate, enhance, and transform images. Many image editing programs are also used to render or create computer art from scratch. The term "image editing" usually refers only to the editing of 2D images, not 3D ones.
The correlates of crime explore the associations of specific non-criminal factors with specific crimes.
The Great Pheromone Myth is a book on pheromones and their application to chemosensation in mammals by Richard L. Doty, director of the University of Pennsylvania's Smell and Taste Center in Philadelphia. Doty argues that the concept of pheromone introduced by Karlson and Lüscher is too simple for mammalian chemonsensory systems, failing to take into account learning and the context-dependence of chemosensation. In this book, he is especially critical of human pheromones, arguing that not only are there no definitive studies finding human pheromones, but that humans lack a functional vomeronasal organ to detect pheromones. Its publication received coverage in the news media, especially concerning its arguments that human pheromones do not exist.
Since their inception in the 1970s, video games have often been criticized by some for violent content. Politicians, parents, and other activists have claimed that violence in video games can be tied to violent behavior, particularly in children, and have sought ways to regulate the sale of video games. Studies have shown no connection between video games and violent behavior. The American Psychological Association states that while there is a well-established link between violent video games and aggressive behaviors, attributing acts of violence to violent video gaming "is not scientifically sound."
Female intrasexual competition is competition between women over a potential mate. Such competition might include self-promotion, derogation of other women, and direct and indirect aggression toward other women. Factors that influence female intrasexual competition include the genetic quality of available mates, hormone levels, and interpersonal dynamics.
After decades of increasing crime across the industrialised world, crime rates started to decline sharply in the 1990s, a trend that continued into the new millennium. Many explanations have been proposed, including situational crime prevention and interactions between many other factors complex, multifactorial causation.
