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.
The Bobo doll experiment is the collective name for a series of experiments performed by psychologist Albert Bandura to test his social learning theory. Between 1961 and 1963, he studied children's behaviour after watching an adult model act aggressively towards a Bobo doll. The most notable variation of the experiment measured the children's behavior after seeing the adult model rewarded, punished, or experience no consequence for physically abusing the Bobo doll.
School violence includes violence between school students as well as attacks by students on school staff and attacks by school staff on students. It encompasses physical violence, including student-on-student fighting, corporal punishment; psychological violence such as verbal abuse, and sexual violence, including rape and sexual harassment. It includes many forms of bullying and carrying weapons to school. The one or more perpetrators typically have more physical, social, and/or psychological power than the victim. It is a widely accepted serious societal problem in recent decades in many countries, especially where weapons such as guns or knives are involved.
Sex differences in crime are differences between men and women as the perpetrators or victims of crime. Such studies may belong to fields such as criminology, sociobiology, or feminist studies. Despite the difficulty of interpreting them, crime statistics may provide a way to investigate such a relationship from a gender differences perspective. An observable difference in crime rates between men and women might be due to social and cultural factors, crimes going unreported, or to biological factors. The nature or motive of the crime itself may also require consideration as a factor.
The study of violence in mass media 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.
The field of psychology has been greatly influenced by the study of genetics. Decades of research have demonstrated that both genetic and environmental factors play a role in a variety of behaviors in humans and animals. The genetic basis of aggression, however, remains poorly understood. Aggression is a multi-dimensional concept, but it can be generally defined as behavior that inflicts pain or harm on another.
Social cognitive theory (SCT), used in psychology, education, and communication, holds that portions of an individual's knowledge acquisition can be directly related to observing others within the context of social interactions, experiences, and outside media influences. This theory was advanced by Albert Bandura as an extension of his social learning theory. The theory states that when people observe a model performing a behavior and the consequences of that behavior, they remember the sequence of events and use this information to guide subsequent behaviors. Observing a model can also prompt the viewer to engage in behavior they already learned. Depending on whether people are rewarded or punished for their behavior and the outcome of the behavior, the observer may choose to replicate behavior modeled. Media provides models for a vast array of people in many different environmental settings.
Leonard David Eron was an American psychologist who conducted one of the longest spanning longitudinal studies on aggressive behavior in children to date. Based on Leonard Eron and Rowell Huesmann's second longitudinal study that they conducted between 1977 and 1995, lead to the conclusion that media violence causes aggressive behavior. Eron was an author of many books, articles and a constant public policy advocate on Capitol Hill. He also twice received Fulbright scholarship and the APA's Award for Distinguished Lifetime Contributions to Media Psychology.
Craig A. Anderson is an American professor and director at the Department of Psychology, Iowa State University in Ames. He obtained his PhD at Stanford University in 1980.
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 short films and television programs with cartoon violence include Rick and Morty, Tom and Jerry, Looney Tunes, The Simpsons, and Family Guy.
The effects of domestic violence on children have a tremendous impact on the well-being and developmental growth of children witnessing it. Children can be exposed to domestic violence in a multitude of ways and goes beyond witnessing or overhearing, although there is disagreement in how it should be measured. Children who are exposed to domestic violence in the home often believe that they are to blame, live in a constant state of fear, and are 15 times more likely to be victims of child abuse. Close observation during an interaction can alert providers to the need for further investigation and intervention, such as dysfunctions in the physical, behavioral, emotional, and social areas of life, and can aid in early intervention and assistance for child victims.
The frustration–aggression hypothesis, also known as the frustration–aggression–displacement theory, is a theory of aggression proposed by John Dollard, Neal Miller, Leonard Doob, Orval Mowrer, and Robert Sears in 1939, and further developed by Neal Miller in 1941 and Leonard Berkowitz in 1989. The theory says that aggression is the result of blocking, or frustrating, a person's efforts to attain a goal.
Neurocriminology is an emerging sub-discipline of biocriminology and criminology that applies brain imaging techniques and principles from neuroscience to understand, predict, and prevent crime.
Examples of misogyny exist in many published forms, within multiple cultures and well-observed works. Technological advances in the modern era have contributed proficient means to media and marketing to the resultant mass media in the 21st century. The merging of misogyny and mass media has made numerous examples where studies have concluded correlations between misogynous messages, both obvious and subliminal. Corresponding physical appearance of violence and hateful conduct may be seen relative to exposure.
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."
Kenneth Dodge is the William McDougall Distinguished Professor of Public Policy and Professor of Psychology and Neuroscience at Duke University. He is also the founding and past director of the Duke University Center for Child and Family Policy and founder of Family Connects International.
Hostile attribution bias, or hostile attribution of intent, is the tendency to interpret others' behaviors as having hostile intent, even when the behavior is ambiguous or benign. For example, a person with high levels of hostile attribution bias might see two people laughing and immediately interpret this behavior as two people laughing about them, even though the behavior was ambiguous and may have been benign.
Dolf Zillmann is dean emeritus, and professor of information sciences, communication and psychology at the University of Alabama (UA). Zillmann predominantly conducted research in media psychology, a branch of psychology focused on the effects of media consumption on human affect, developing and expanding a range of theories within media psychology and communication. His work centred on the relation between aggression, emotion, and arousal through media consumption, predominantly in pornography and violent genres of movie and television. His research also includes the effects of music consumption, video games, and sports.
