The Psychology of Violent Behaviour

The Psychology of Violent Behaviour
Dr. Kevin Douglas

Psychologists, like many people in society, have long puzzled over violence. What causes it? How can we predict it? How can we reduce it?

Violence is a salient public health concern that affects hundreds of thousands of Canadians annually, and costs society enormously. Why do some people act in a chronic and persistently violent manner?

Psychological science has identified a number of risk factors for violent behaviour, as well as possible means by which to reduce the risk for violence.

Several topics being studied by SFU researchers are highlighted. For instance, the role of major mental illness (i.e., schizophrenia) is a controversial, yet potentially important, phenomenon to understand in terms of its relationship to violence.

Certain personality traits, such as psychopathic personality, also have implications for violence, as do procriminal attitudes, and alcohol and drug problems.

Certain background factors (parental criminality; abuse) and contextual considerations (neighbourhood characteristics; stability of housing) elevate the risk for violent behaviour.

Importantly, social scientific research has identified promising violence reduction strategies that have been demonstrated to reduce violent behaviour. The presentation will conclude with suggestions for how psychological science can contribute to the reduction of violent behaviour in society.

  • The Media is the main cause of violence worldwide I think……. kids grow watching power rangers and and such this tells the audience that violence can save the day

  • Intriguing.

  • You must assume you are wrong and have false ways that God hates unless (or until) you have perfectly known God through His Spirit. You must be perfect or you will not escape the hell-fire wrath of God. So, to avoid the coming judgment, dedicate your life to finding out what is wrong with every religion.

  • Do diligent and hard research as you beg God to forgive you. Also warn others to do the same. Make this your entire life to warn and be warned in this way. You don't have time for the idle entertainment of this world. You must come to know the whole truth to be saved from the wrath of God. You have been warned! Now, get to work and quit playing around.

  • Watch Derren Brown, he's pretty good at manipulating-behaviorism!

  • He mentioned empathy training not being effective, but he didn't talk about the risk of psychopaths getting better at pretending to be empathetic! There have been findings of psychopaths getting worse (i.e. more powerful, just as evil) from it.

  • The graph at 23:00 lacks crucial information. The x axis should be labelled to indicate that low and high refer to the patient's score on the psychopathy rubric. Even more useful would be an actual score for comparison, and the name of the test in question, which would let a skeptic check the experiment for criticism or look it up out of curiosity.

  • I really dislike the term 'mental illness.' I don't believe such a thing exists and there are no known tests to show chemical imbalances in the brain. It's all a hoax manufactured by Big Pharma to make billions of dollars. I've been 'diagnosed' with bipolar disorder and I can tell you 100% that I can control my anger if I put all of my focus and attention on doing so. Psychotropics work against that. At least in my case.
    Nonetheless, great video, very informative.

    Lol… robbery is WAY too high on that list.

  • video describes psychology of violent behaviour and many other factors related to violence Certain personality traits, such as psychopathic personality, also have implications for violence, as do procriminal attitudes, and alcohol and drug problems,he also discusses about Violence in many forms is preventable. There is a strong relationship between levels of violence and modifiable factors such as concentrated poverty, income and gender inequality, the harmful use of alcohol, and the absence of safe, stable, and nurturing relationships between children and parents. Strategies addressing the underlying causes of violence can be effective in preventing violence

  • Very informative and articulate delivery. TY. 😉

  • What are the mental disorders of violence people?

  • Some folks are tired of reporting crimes when nothing is done about it except for the Perpetrator getting even, when you turn him/her, causing the stats. being skewed..

  • awesome!

  • It's so interesting. 👍

  • youre dead wrong! and just because u have ur own experience..ud ont speak for others! if the brain is powerful enough to act out on suidcidal thoughts..dont tell me mentla illness doesnt exist!! how despicabl e of u!

  • cool
