CHP 5 TB: Genes, Culture, and Gender Flashcards
We not only share common biology but common…
behavioral tendencies
universal behaviors and language patterns
Humans are intensely…
- social
- we join groups and conform
- recognize distinctions of social status
Where do universal behaviors rise from?
from our biological similarity
they define human nature
Shipman 2003
- we are all african
- people migrated from Africa to various parts of the world due to climate change/food availability
- those who went north developed lighter skin pigments compared to those who stayed in africa
Define Natural selection
the evolutionary process by which heritable traits that best enable organisms to survive/reproduce in environments are passed to the next generations
basically, the traits that best promote survival and reproduction of an organism in an environment are passed to their offspring/next generation
Name the key points of
“natural selection enables evolution”
- organisms have numerous/various offspring
- offspring compete for survival in environment
- certain biological/behavioral INCREASE their chance of survival/reproduction
- offspring that do survive/reproduce end up passing those traits onto the next gen
- general population characteristics change over time as well
Natural selection genes that increase survival long enough for reproduction become….
MORE ABUNDANT
define evolutionary psychology
the study of the evolution of cognition/behavior using principles natural selection
Charles Darwin 1859, natural selection
evol. psych
Why are humans the way they are…
because nature selected those who had more advantageous traits
evol. psych
What does natural selection predispose…
it predisposes psychological traits and social behaviors that enhance preservation and the spread of genes
Evol. psych
What are human brains the product of?
they are the product of what helped our hunter-gatherer ancestors survive
What do we long for from our ancestors in terms of evolutionary psychology?
we long for the wahtever helped them survive, reproduce and nurture their offspring to –> survive/reproduce
even negative emotions
What is one of the most researched areas in SOCIAL PSYCH?
gender differences
Gender
Define sex
- biological categories (male/female)
- based on chromosomes, genitals and secondary sex characteristics
biological assignment
define gender
- Refers to the socially constructed roles, behaviors, activities and attributes that a given society considers appropriate for men and women
what do i feel i am? no based on biology
What has changed with the terms** sex and gender** with time?
- these terms used to be very rigid but not anymore
- doctors advise that surgery for intersex children be postponed until they express their identity
- **some people identify as gender fluid or non binary **
time has changed these terms basically
Define transgender
- someone whose psychological sense of being male or female differs from their birth sex
gender and mating preferences
Describe male preferences in mating
- have unlimited reproductive capabilities
- favor youthful appearances and characterisitics that suggest fertility
- stronger sex drive because it is a cheaper investment
- men compete with other men for chances to win genetic sweepstakes (sending their genes into the future)
men look to reproduce widely not wisely like women
gender and mating preferences
Describe female mating preferences
- look for signs of resources and commitment in mating partners
- look for men who can provide external resources and physical protection for offspring
- mating is a great investment in each child and reproduction capabilities are limited
men will strive to provide what a woman wants in a partner
gender and mating preferences
What do both men and women look for in partners
kindness, love, and mutual attraction
gender and hormones
What are the two ways sex differences are rooted biologically?
Hormones and Role Demands
gender and hormones
What is the hormone that plays a crucial part in differences in dominance and aggression?
Testosterone
* it is more prevalent in men than women
men tend to be more aggressive (influenced by T)
