Aggression
- Behavior which intends to cause hurt or harm.
- Hostile Aggression: elicited by anger
- Instrumental Aggression: calm, pragmatic aggression (e.g. used by the court system to punish wrongdoers)
- Frustration-Aggress Hypothesis:
- Frustration in achieving a goal -> Anger -> Aggression
The Biology of Aggression
Theories of Aggression
Psychodynamic view:
- Emphasises the innate/instinctual aspect of aggression
- Triggers include anger, frustration, shame
Evolutionary view:
- All animals display the capacity to harm or kill other members of their
species
- Aggression: strategy evoked when survival or reproductive success is
threatened
The Biology of Aggression
- Aggression is controlled by the brain
- Can be evoked by electrical stimulation of the hypothalamus and the amygdala
- Lesions of the amygdala produce a tame animal
- Aggression is modulated by hormones testosterone and serotonin
- Genetics: Animal studies reveal that an aggressive temperament can be inherited
Theories of Aggression
Cognitive neoassociation theory: Exposure to aversive stimuli trigger aggressive thoughts and actions.
Cognitive-social perspective: Aggression results from reward, punishment, cognitive processes and social learning
General aggression model: Person and situation variables combine to determine the presence of aggression
Conflict
- Perceived incompatibility of actions, goals, or ideas.
- Social Trap: Conflicting parties each rationally pursue self-interest and become caught in mutually destructive behavior.
Notes
Person Perception
- Person perception is the process of forming impressions of others.
- Perceptions of others can be influenced by a variety of factors, including physical appearance. People tend to attribute desirable characteristics such as sociable, friendly, poised, warm, competent, and well adjusted to those who are good looking. People use social schemas, organized clusters of ideas about categories of social events and people, to categorize people into types.
- Stereotyping is a normal cognitive process involving widely held social schemas that lead people to expect that others will have certain characteristics because of their membership in a specific group. Gender, ethnic, and occupational stereotypes are common.
- Person perception is a subjective process. Stereotypes may lead people to see what they expect to see and to overestimate how often they see it (illusory correlation).
- Evolutionary psychologists argue that many biases in person perception were adaptive in our ancestral past, for example, automatically categorizing others may reflect the primitive need to quickly separate friend from foe.
