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.
Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior that includes theft, lies, physical violence that may lead to destruction, and reckless breaking of rules, in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as "antisocial behaviors", and is often seen as the precursor to antisocial personality disorder; however, the latter, by definition, cannot be diagnosed until the individual is 18 years old. Conduct disorder may result from parental rejection and neglect and can be treated with family therapy, as well as behavioral modifications and pharmacotherapy. Conduct disorder is estimated to affect 51.1 million people globally as of 2013.
In sociology, a peer group is both a social group and a primary group of people who have similar interests (homophily), age, background, or social status. The members of this group are likely to influence the person's beliefs and behaviour.
Mobbing, as a sociological term, refers either to bullying in any context, or specifically to that within the workplace, especially when perpetrated by a group rather than an individual.
Bullying is the use of force, coercion, hurtful teasing or threat, to abuse, aggressively dominate or intimidate. The behavior is often repeated and habitual. One essential prerequisite is the perception of an imbalance of physical or social power. This imbalance distinguishes bullying from conflict. Bullying is a subcategory of aggressive behavior characterized by hostile intent, imbalance of power and repetition over a period of time.
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.
Relational aggression, alternative aggression, or relational bullying is a type of aggression in which harm is caused by damaging someone's relationships or social status.
School bullying, like bullying outside the school context, refers to one or more perpetrators who have greater physical strength or more social power than their victim and who repeatedly act aggressively toward their victim. Bullying can be verbal or physical. Bullying, with its ongoing character, is distinct from one-off types of peer conflict. Different types of school bullying include ongoing physical, emotional, and/or verbal aggression. Cyberbullying and sexual bullying are also types of bullying. Bullying even exists in higher education. There are warning signs that suggest that a child is being bullied, a child is acting as a bully, or a child has witnessed bullying at school.
Peer victimization is the experience among children of being a target of the aggressive behavior of other children, who are not siblings and not necessarily age-mates.
