BEHAVIOUR = PSYCHOLOGICAL MECHANISIMS + INPUT
EVOLVED PSYCHOLOGICAL MECHANISMS CODED IN THE BRAIN
EVOLVED PSYCHOLOGICAL MECHANISMS CAN BE DESCRIBED AS
INFORMATIION PROCESSING DEVICES
Help to drive key decisions in order to behave in an adaptive fashion
1. genes and family resemblances
there is a folklore that people tend to notice similarities and the newborn
infant in the father more so than the mother.
In reality if people are shown a newborn infant, they don’t necessarily notice
real diff between father and mother,
2. differences that may exists in opinions and approaches to romantic
what do females look for in a potential partner for romantic relationship?
Honesty, humorous, strong, commitment, protector and provider, able to
What do men look for?
Fideility, physical attractiveness, cook food, confidence, sex. Men seem to
really value physical qualitirs in a potential romantic partner
Whereas women, a lot of things that you hear have to deal with quality of a
person and as well as potential resources that person may have access to.
ROMANCE IN THE FRIEND ZONE
MEN WERE MORE LIKELY TO REPORT TO BEING ATTRACTED TO THEIR
MEN TENDED TO THINK THAT WOMEN FRIENDS WERE ATTRACTED TO THEM
AS WELL. MEN ALSO SAID THEY WOULD DATE THEIR LADY FRIENDS.
DIFFERENT ADAPTIVE PROBLEMS
metabolic demands of reproduction huge metabolic cost with respect to
females compared to males
parental investment may have been different for men and women,
women have gestational period whereas for the male its much easier for
the male to not be involved in parental investment.
Genetic cuckoldry infant has come out of her, she can be 100% sure
that she Is the mother of the infant.
Almost like a conditioned response for the family of the mother to tell the
father how much the father looks like the child.
Low variance not many outcomes
High variance many outcomes
RISK TAKING BEHAVIOUR
people murder others for material goods many homicides two people
may have known each other but at some point there is a challenge to one
of the other persons social status or a rivalry between a woman.
people who are more likely to commit homicides/lethal competition are
people who have very little to lose. homeless, bottom of economic
spectrum, no real prospects of moving up, most to gain in gaining in
lethal competition, single, not very social, evolutionary not much
opportunity to lead descendants , limited access to those kinds of
unemployed and male, more likely and spikes at early 20s age. Less
access to resources, which is something a potential female partner may
be looking for, and you don’t have that.. behaviours that lead to
homicide. the greater income inequality, the greater the increase in homicide rates.
If less income inequality, the overall homicide rate is much lower than
others. NEUROSCIENCE 1 AND 2 1/21/2013 10:33:00 AM
CASE STUDIES THAT DEMONSTRATE THE COMPLEXITY OF THE
Provide natural experiments if an accident happened to someone’s brain, we
can observe certain behaviors and may reveal underlying mechanisms and
what’s happening in the healthy and unhealthy brain.
People that you know and have an emotional connection with, suddenly a
person believes that they are imposters Freudian explanation there is
an unconscious attraction to his mother that he has been keeping
suppressed and damage to head causes release but incompatible with the
way society accepts things and then the disbelief that she is his mother
Imposter syndrome : specific to people that he knows well and has
emotional attachments to.
Part of telling yourself a self narrative and fooling yourself.
