Social withdrawal can be an early warning sign a person is violent or aggressive, according to Summit Research Laboratory. A person may begin isolating themselves because they constantly feel rejected or persecuted by others and may withdraw to solitude as a coping mechanism.
Quick Loss of Temper
Those prone to violence may exhibit extreme impulsiveness, according to the American Academy of Child & Adolescent Psychiatry. This behaviour tends to be both frequent and intense. If a person seems easily thrown off balance and experiences intense bursts of anger or frustration, this can be a sign of violent behaviour.
Expressions of Violence
Children and adolescents have a tendency to express violent behaviour via artwork or writing. Vague depictions of violence with unidentified victims or those related to television shows or movies are not generally considered to be dangerous. An excessive depiction of violence, however, can indicate a tendency toward violent behaviour. This can include pictured or written violence against a specific person, such as a family member or teacher.
Because this also is a creative outlet for a young person, it’s important not to accuse a child of negative behaviours until you can be certain those behaviours are truly cause for worry. A mental health professional can help you to determine if the behaviour may be dangerous.
Those who display aggressive or hostile behaviour may have unrealistic or unfair attitudes toward others, especially certain social groups. Displaying prejudice toward individuals because of race, religion, sexual orientation or physical attributes can indicate a violent or hostile person. If a person joins a hate group or has verbally or physically assaulted those who are different, this can indicate aggressive or hostile behaviour.
