Bullying02:04

Bullying

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 bullying.
Aggression01:47

Aggression

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 hire...
Bystander Effect02:09

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Its origins lie in both biological imperatives and sociocultural conditioning, making it a multifaceted psychological construct. Although universally experienced, the triggers and expressions of jealousy vary notably between individuals, especially across genders, due to evolutionary pressures and cultural influences.Gender Differences and Evolutionary TheoryEvolutionary theory explains...

Intentional torts in healthcare refer to deliberate actions that cause harm or infringe on the rights of others. Understanding these torts is crucial for healthcare professionals to avoid legal liabilities and maintain ethical standards in patient care.
Types of Stressors01:23

Types of Stressors

A stressor is any event, condition, or stimulus that triggers stress and causes a physical or psychological response in the body. Stressors can be categorized into three main types: catastrophes; significant life changes; and daily hassles, including social stress. Each can be detrimental to physical and mental well-being.

Area of Science:

  • Forensic Psychology
  • Criminology
  • Mental Health

Background:

  • Stalking is a recognized precursor to violence, yet accurately identifying high-risk individuals remains challenging.
  • Previous research has limitations in assessing risk factors for diverse stalker typologies.

Purpose of the Study:

  • To identify specific risk factors predicting violence across different stalker types using a pseudo-prospective design.
  • To enhance the accuracy of risk assessment for stalking behavior.

Main Methods:

  • Collected demographic, behavioral, and diagnostic data from 211 individuals referred to a community forensic mental health service.
  • Utilized odds ratios, chi-squared tests, and logistic regression to identify risk factors for stalking violence.
  • Assessed model predictive utility with receiver operating characteristic curves.

Main Results:

  • For rejected ex-intimate stalkers, prior violence and threats were significant predictors of violence (AUC=0.75).
  • For other stalker types, younger age (<30), substance use, and prior violence predicted violence (AUC=0.80).
  • Approach behaviors and psychosis were less effective in predicting stalking violence.

Conclusions:

  • Stalker motivation and relationship type, combined with specific risk factors, enable accurate identification of those at increased risk of violence.
  • Prior violence and threats are critical indicators, particularly for ex-intimate stalkers.
  • Risk assessment models can be improved by focusing on motive-specific factors rather than general indicators like psychosis.
