Aggression01:47

Aggression

30.6K
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...

Secondary Motives: Affiliation Motivation and Aggression Motivation

905
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...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Self-Regulation01:25

Self-Regulation

312
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Egoism and Altruism

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

Area of Science:

  • Psychology
  • Social Psychology
  • Behavioral Science

Background:

  • Theoretical frameworks suggest a link between ego-depletion and aggressive behavior.
  • Understanding the interplay between self-control and aggression is crucial for behavioral science.

Purpose of the Study:

  • To experimentally assess the relationship between ego-depletion and aggressive behavioral change.
  • To determine if provocation moderates the effect of ego-depletion on aggression.

Main Methods:

  • Participants were assigned to high or low ego-depletion conditions via memorizing numbers of varying lengths.
  • Aggression was measured by participants taking raffle tickets from a partner.
  • Provocation was introduced by the partner's ticket-taking behavior over three exchanges.

Main Results:

  • Aggression levels were highest among participants who were both ego-depleted and provoked.
  • Ego-depletion alone did not lead to the highest aggression, indicating a moderating effect of provocation.
  • Behavioral changes in aggression were observed across repeated interactions.

Conclusions:

  • Ego-depletion, particularly when combined with provocation, is a significant factor in escalating aggressive behavior.
  • Findings align with and extend the General Aggression Model and the Strength Model of Self-Control.
  • The study provides empirical evidence for the interaction between self-control resource depletion and situational aggression triggers.
