Chapter 10 Flashcards
Define aggression
intentional behaviour aimed at causing physical/psychological pain to those who do not wish to be harmed
Define violence
aggression that has extreme physical harm, such as injury or death, as its goal - subset of aggression
Define proactive aggression, how can we also call it?
goal and outcome directed, calculated/thought out
• AKA Instrumental/cognitive aggression
Define reactive aggression, how can we also call it?
in response to a provocation, not thought out AKA hostile (coming from affect, want to inflict pain), emotional, impulsive aggression
What do researchers think about the proactive/reactive dichotomy?
Researchers argue that this dichotomy is not actually accurate: it’s a spectrum
Define physical aggression (Ex)
hitting pushing, biting
Define non-physical aggression (ex)
verbal (name-calling), relational (more covert, focused on social group)
Define relational aggression, who engages most in it?
- Stereotypic “mean girl” behaviour
- Intentionally harming another person’s social relationships
- It has been researched that females actually engage more in it; goal is to remove someone from a group - not just a stereotype
- This type is maintained while growing older; it stays
Aggression is adaptive. Name the 2 evolutionnary reasons males engage in aggression
- Establish dominance over other males
* Protect paternity through jealousy-motivated aggression
Explain the experiment with the rat and the cat: what happened? What does this show?
raised a rat with a cat in the same environment - the cat refused to chase rats afterwards, because they bonded together
shown that aggression is both instinctual and learned
What is the relation with aggressivity in childhood and adlthood?
- Children who are aggressive as infants are also aggressive when adults
- Behavioural genetics studies have found that criminal and aggressive behaviour is correlated at about .7 for identical twins and only at about .4 for fraternal twins
Describe the study about the MAOA gene
MAOA gene: produces serotonin
Low activity of MAOA = significantly more at risk to show a variety of aggressive behaviours in groups that were probably and certainly assaulted as children
Explain the 2 routes of the amygdala to process emotion
- Fast route (thalamus -> amygdala), bottom-up process
* Slow route (thalamus -> prefrontal cortex -> amygdala), top-down process
How will a lesion of the amygdala influence aggressive behaviour?
• Lesion will decrease behaviour
What role does testosterone play in aggressive behaviour?
- Affects the limbic system - increased emotional reactivity and heightened emotional vigilance
- More rough and tumble play in children - both males and females with higher levels of testosterone
Describe the experiment with serotonin. What were the results?
Experiment: 80 men and women, 1/2 had history of aggression
Divided into 2 groups
Low group: no history of aggression - high: history
Competitive reaction time game with a fictional opponent - the winner was allowed to shock the loser
Took serotonin reuptake inhibitor or placebo
Could gamble on the shock they would receive if they lost
Goal: situation where they felt provoked
In high group: those that received serotonin showed significantly lower aggression response
Serotonin plays a role in attenuating the effect of provocation
Why are chimps more aggressive than bonobos?
Chimps are aggressive
• Patriarchal society (aggression towards females)
• To be considered a male they have to attack females
* Bonobos live in forests where the food is easily available (plants) * Chimps sometimes live in areas where there are also gorillas who take all the plants, they need to forage in trees and fight for their food
Name the 3 main effects of alcohol that can interfere with aggressive behaviour
Decreased inhibition
Alcohol myopia
Alcohol expectancy
Define alcohol myopia
○ More self-focused and less aware of the social situation (ignore social norms, seek immediate gratification)
