Chpt 4 Test Flashcards
What’s an EEG?what does it measure?
Electroencephalograms -measures brain waves
What did kohlshutter study? And how?
Sleep depth and with the amount of noise it took to wake some one up at a certain time in there sleep
Deff of tabla rosa
Concept that says people are born knowing nothing a “blank slate”/born with an open mind/learning is just a particular instinct
For humans as a species are males and females similar?
Yes very, compared to other species
What is more developed in the human female than males?
Corpus colusum, so the female is more likely to use her whole brain
What is the female sex hormone? What can it be found in
( commercially)? What does it make women more sensitive too?
Estrogen. Birth-control, and social situations
What is the male sex hormone? What can it be found in? What does it make men more Likely todo?
Testosterone. Steroids. Risk taking behavior.
Nature deff?
Born with all mechanics needed to survive
Nurture deff?
You learn through out your life
Who founded the theory of evolution?
Darwin
When was Darwin’s theory published?
Just before the civil war
What’s a weird fact about Darwin’s family?
Lots of intermarriage and they were very involved in the sciences
Who was Darwin sent around the world with?
British navy
What was his most interesting specimen? Why?
The finches. When he collected them from island to island the all had their differences to make them more fit to their environment but they all visibly had a common ancestor
Biggest parts of Darwin’s evolutionary theory?
Survival of the fittest
What do social Darwinists believe?
We should approach human reproduction, the same as animal husbandry
What is eugenics?
Out staining individuals should be encouraged to reproduce and the inferior should not be allowed to reproduce or completely taken from the population
Who used an extreme form of eugenics?
Nazis
What part of the brain develops faster in females than males?what does this give women an advantage in? Til what age do women have the advantage?
The frontal. In ability to process risk faster and deeper than men. Til mid 20’s.
Sleep phenomenon is linked to what?
Biological processes
What was the big sleep question in the 60’s?
Could astronauts sleep in space?
Behavior genetics:
Study of the relative power and limits of genetic and environmental influences on behavior
Environment
Every non genetic influence from prenatal nutrition to the people and things around us.
Chromosomes
Threadlike structures made of DNA molecules that contain the genes
DNA
A complex molecule containing the genetic information that Makes up chromosomes
Genes
The biochemical units of heredity that make up chromosomes; a segment of DNA capable of synthesizing a protein
Genome
The complete instructions for making an organism, consisting of all the genetic material in the organisms chromosomes
Identical twins
Twins who developed from a single fertilized egg that splits in 2 creating 2 genetically identical organisms
Fraternal twins
twins who develop from seep rate fertilized eggs. They are genetically no closer than brothers and sisters but they share a fetal environment
Temperament
A persons characteristic emotional reactivity and intensity
Molecular genetics
The subfield of biology that studies the molecular structure and function of genes
Heritability
The proportion of variation among individuals that we can attribute to genes the heritability of a trait may vary depending on the range of populations and environments studied
Interaction
The interplay that occurs when the effect of one factor (such as environment) depends on another factor (such as heredity)
Epigenetics
The study of influences on gene expression that occur without a DNA change
Evolutionary psychology
That study of the evolution of behavior and the mind using principles of natural selection.
Natural selection
The principle that among the range of inherited trait variations, those that lead to increased reproduction and survival will most likely be passed on to succeeding generations
Gender
The biologically and socially influenced characteristics by which people define male and female
Culture
The enduring be be behaviors, ideas, attitudes, values and traditions shared by a group of people and transmitted from one generation to the next
Norm
An understood rule for accepted and expected behavior. Prescribe “proper” behavior
Individualism
Giving priority to ones own goals over group goals and defining ones own identity in terms of personal attribute rather than group identifications
Collectivism
Giving priority to the goals of ones group (often ones extended family or work group) and defining ones identity accordingly
X chromosome
The sex chromosome found in both men and women females have two X chromosomes and men only have one an X chromosome from each parent produces a female child
Y chromosome
The sex chromosome found j. Only males when paired with an X chromosome from the mother it produces a male child
What does testosterone stimulate the growth of in fetus development?
Male sex organs
Role
Set of expectations about a social position defining how those in then position defining how those in the position ought to behave
Gender role
A set of expected behaviors for males or for females
Social learning theory
The theory that we learn social behavior by observing and imitating and by being rewarded or punished
Gender identity
Our sense of being male or female
Gender typing
The acquisition of a traditional masculine or feminine role
Transgender
An umbrella term for describing people whose gender identity or expression differs associated with their birth sex
What is SAD?
Season affective disorder
What kind of change does jetlag incure?
Biological clock
What are two circadian rhythms?
Biological clock and menstural
