Aggression01:47

Aggression

30.0K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Conduct Disorder01:28

Conduct Disorder

396
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Longitudinal Research02:20

Longitudinal Research

13.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Bullying

8.7K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Psychological and Sociocultural Causes of Schizophrenia01:29

Psychological and Sociocultural Causes of Schizophrenia

393
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Area of Science:

  • Forensic Psychiatry
  • Clinical Psychology

Background:

  • Historically, chronic aggressors were studied as a single group.
  • This research aimed to subdivide chronic aggressors based on consistent physical aggression over multiple years.

Purpose of the Study:

  • To identify common characteristics that could classify chronic aggressors into aggressive or nonaggressive subgroups.
  • To determine if specific clinical and demographic factors differentiate consistently aggressive patients from nonaggressive controls.

Main Methods:

  • Reviewed patients within a forensic hospital system who committed at least 5 acts of physical aggression per year for 3 years.
  • Collected and compared data on clinical and demographic characteristics of aggressive patients against matched nonaggressive controls.

Main Results:

  • Two significant variables, cognitive disorder and history of suicidal behaviors, were identified.
  • These variables accurately classified 76.7% of the cases into aggressive or nonaggressive groups.

Conclusions:

  • Cognitive disorders, history of suicidal behavior, and increased age are associated with this subgroup of aggressive patients.
  • Clinicians should consider cognitive rehabilitation and social cognition treatments for these patients to reduce aggression.
