Aggression is overt or covert, often harmful, social interaction with the intention of inflicting damage or other harm upon another individual; although 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, from frustration due to blocked goals to feeling disrespected. 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 behavior 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. 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 in school. It is widely believed by society to have become a serious 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 for example, testosterone or sociobiological theories). The nature of the crime itself may also require consideration as a factor.
The studies 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 what is mainly believed.
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.
Workplace aggression is a specific type of aggression which occurs in the workplace. Workplace aggression can include a wide range of behaviors, ranging from verbal acts to physical attacks. Workplace aggression can decrease the ability of a person to do their job well, lead to physical declines in health and mental health problems, and can also change the way a person behaves at their home and in public. If someone is experiencing aggression at work, it may result in an increase in missed days and some may decide to leave their positions.

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.
The effects of domestic violence on children have a tremendous impact on the well-being and developmental growth of children witnessing it. Children who witness 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 Center on Media and Child Health (CMCH) is a non-profit organization based at Boston Children's Hospital. CMCH was founded in 2002, by Michael Rich, pediatrician; Associate Professor of Pediatrics at Harvard Medical School; and Associate Professor of Society, Human Development, and Health at Harvard T.H.

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 1969. 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, empirical research finds there is little to no evidence connecting violence to video games.

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.
