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...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Secondary Motives: Affiliation Motivation and Aggression Motivation01:21

Secondary Motives: Affiliation Motivation and Aggression Motivation

Affiliation motivation is the intrinsic desire to connect with others and belong to a social group, which plays a crucial role in forming and maintaining personal relationships. This type of motivation is essential for psychological well-being, as it provides individuals with a sense of community and support. An example of this is a student who joins a study group in order to feel a sense of connection. People with high affiliation motivation actively seek social approval, take satisfaction in...
Deviation from Ideal Behaviour01:23

Deviation from Ideal Behaviour

Real gases do not perfectly obey the ideal gas laws, especially at high pressures and low temperatures or when they are about to condense to a liquid. These deviations occur due to intermolecular forces between gas molecules. Repulsive forces aid expansion and are significant when molecules are very close together, typically at high pressure. Attractive forces assist compression and have a longer range, being effective over several molecular diameters. They become significant when molecules are...
Conduct Disorder01:28

Conduct Disorder

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;...
Borderline Personality Disorder01:25

Borderline Personality Disorder

Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Summary
This summary is machine-generated.

A theory of marginal deviations explains how slight antisocial behavior can escalate to serious outcomes. About 8% of the population may transition from minor to major deviance over time.

Area of Science:

  • Psychology
  • Sociology
  • Criminology

Background:

  • Marginal deviations represent initial, slight departures from social norms.
  • Understanding the progression from minor to severe antisocial behavior is crucial for intervention.

Purpose of the Study:

  • To present a theory of marginal deviations.
  • To articulate the processes transforming slight deviance into serious antisocial outcomes.
  • To identify factors influencing the escalation or attenuation of deviant behavior.

Main Methods:

  • The study proposes a theoretical framework based on self-fulfilling prophecies and dynamic systems theory.
  • Evidence is presented regarding the prevalence of marginal and serious deviance.
  • Hypotheses are formulated for future empirical testing.

Main Results:

  • Approximately one-third of the population exhibits marginal deviance.
  • About one-fourth of those marginally deviant (8% of the total population) become seriously deviant over time.
  • Key factors include the child's behavior, peer judgments, and social interactions.

Conclusions:

  • Marginal deviations can escalate to severe antisocial outcomes through specific social and psychological processes.
  • Assimilation and attenuation can lead back to normative behavior.
  • Accommodation and amplification can accelerate deviance toward more serious outcomes.
