• Logic of Prisoner’s dilemma
Each of two criminals is offered immunity from prosecution in exchange for a confession. If both stay silent, both get off with a light sentence on a minor charge (upper left). If both confess, both receive a moderate sentence (lower right). But if one turns state’s evidence while the other stays mum, the confessing criminal goes free and the silent one spends a long time in jail. (best strategy – tit for tat – mimic other person)
• real life Social dilemmas of prisoners game
public goods (certain threshold of people have to contribute for it to be there – blood bank, voting, taxes, EC in 101), common dilemmas (opposite – if too many people use the resource they all suffer – grazing sheep, water)
• 2 Influences on solutions of social dilemmas (prisoners game)
psychological factors and situational factors
• Factors that increase the chances of cooperation
group identity (make a name, feel bonded), norms of fairness (individual or collective sense), norms of punishment (we’re evolutionarily wired to get mad at cheaters, also to seek revenge at a cost to ourselves), accountability, reputation, reciprocity, pay it forward
• Aggression
- any behavior that involves the intention to harm someone else
• Roles of serotonin and testosterone
serotonin (low levels associated with being impulsive), testosterone (high level can have an effect but not as clear)
• Kluver-Bucy Syndrome
really high sexual drive because of a damaged amygdala
• Frustration-aggression hypothesis
frustration leads to aggressive behavior, even pinning infants arms makes them lash out
• Culture of honor study - aggression
there are nonviolent societies, US is a moderately aggressive culture, within US “culture of honor” in the South and West - subcultures where we’re cultured our males to defend their turf and their honor - Southern men seen as more polite than Northern men, but if their turf is threatened they can get aggressive - had insult/no-insult condition, this suggests that we’re not an inherently violent species
- Some explanations for altruism
- Cost of not helping would be more detrimental because you would feel bad and not be able to live with yourself
- Evolutionary psychology explanations – kin selection (more likely to help those who share our genes), norms of reciprocity
- Social exchange explanations – still self-interest, to maximize our rewards (reciprocity norm, gain social approval, increase self-esteem), minimize our costs (reduce our own distress)
- Can ease other’s distress if you identify with them (swap places in a shock study if you feel empathy)
• Influences on whether or not people will help
urban overload hypothesis, p luralistic ignorance, diffusion of responsibility, bystander intervention effect, time pressure, social norms
• Urban-overload hypothesis
when we’re in dense the urban-overload hypothesis - when we’re in dense crowded conditions, we shut down a little bit and are less likely to help
o the unhelpful crowd - why? 3 things
diffusion of responsibility and the bystander effect - put them in situation where smoke is coming into room where you’re filling out forms - if you’re alone, probably will go do something, if there are others and they don’t react, they often don’t, in another study, if you hear something bad in the next room, more likely to go get help if they’re alone, but if with others, assume someone else will do it, or that it’s not as big a problem - called pluralistic ignorance (if nobody else is concerned, I don’t want to stick out)
- The difference between cross-sectional and longitudinal research designs
- Cross-sectional studies – comparing different groups to make inferences about both (ex – young and old)
- Longitudinal research designs – reassessing the same participants over time to years to look at change
• Dynamic systems theory
the view that development is a self-organizing process, where new forms of behavior emerge through consistent interactions between a biological being and his or her cultural and environmental contexts
• Explains emergence of new behaviors (dynamic systems theory)
new behaviors occur through person’s active exploration of environment and constant feedback from that environment – every new behavioral skill to emerge is the result of a complex and dynamic system of influences
• Synaptic pruning – why?
use it or lose it – have more synapses than they need – focus on those use and myelinate important circuits, brain organizes itself by what it considers to be important environmentally
• The impact, short- and long-term, of poverty and malnutrition on early brain growth
less myelination, lack energy to interact with objects and people in their environments, lack of stimulation creates deleterious effects that change them throughout life
• Piaget - basic ideas
believed that children develop cognitively through interactions with their environment – 4 stages of cognitive development
• Assimilation
placing a piece of information into a bin that is pre-existing
• Accommodation
taking a new piece of information that doesn’t fit into existing schemas and creating a new one
What are the 4 stages of cognitive development according to Piaget? Yrs?
Sensorimotor (0-2), Preoperational (2-7), Concrete operations (7-11), Formal Operations (11+)
• Sensorimotor
(0-2) – uses senses and motor skills to explore/develop cognitively, no object permanence (slowly develops), A not B phenomenon
• Preoperational
(2-7) – capacity to represent world using symbols, including language, but errors in thinking – lack conservation (centration, reversibility), confuse appearance and reality, egocentrism
