Genetics and evolutionary foundations of behavior Flashcards
How much do human’s genes match Chimpanzees
98.8%
-Psychological structure
-traits/Tendency
-Influence behavior, not directly but indirectly
Genes
-anywhere its the same
Specietypical
-information
-have gene segment
-affect development
DNA
-a change to gene’s DNA sequence to produce something different
-A mistake
Genetic Mutation
-with high hormones, gives more stress
-usually found in coffee
Cortisol
-to modification on as a result of changed life circumstance
Adaption
-refers to the set of genes that the individual inheritsSGe
Genotype
-the observable properties of the body and behavioral trait
Phenotype
-environment effect to genes
-gene regulating activity that doesn’t involve changes to the DNA code and that can persist through one or more generation
-We inherit from our parents not only DNA
Epigenetics
-many genes are needed behavior traits
-One gene is not enough
Polygenic
-Have different level of spectrum
-Ex. Depression
Continous
-very specific
-in or you’re out
Categorial
Genetics can be distinguish between
-Coding genes
-Regulatory genes
-codes for unique protein molecules
Coding genes
-Help activates or suppress specific coding genes and thereby influence the body’s development
Regulatory Genes
-does not alter the protein with a gene will produce but rather influences whether the genes will produce the protein at all
DNA Mythelation
-do not produce their proteins that is they are “shut off”
Mythelated genes
-occurs in sexual reproduction
Reshuffling of genes
-errors that occasionally and unpredictably occur during DNA replication, causing the “replica “ to be not quite identical to the original
Mutations
-Natural theologian
William Paley
-Evolution
-Natural selection
Charles Darwin
-Selfish Gene
-Blind watchmaker
Richard Dawkins
-the long-term adaptive process spanning generations that equips species for life in its ever changing natural habitat
Evolution
-Variation due to chance alone without selection
Genetic drift
-has designs with purpose that had been passed around
Ancestral
- ‘what ever natural is good’
Natural fallacy
-assumption that genetic influences on our behavior take the form of genetic
Deterministic Fallacy
Genetic variability two main sources
-Reshuffling of genes
-Mutations
-some traits that evolved because they served the needs of our ancestors are no longer functional today
Vestigal Characteristics
To survive apes & Monkeys cling onto their mother’s fur in evolution, we los our fur so infants cant clinv onto us anymore, however the reflex remain
Grasping reflex
Usefulness
Functionalism
-Explains ultimate cause for a phenomenon in evolutionary sense
-what happened 1000 years ago
-explains how genetic info. Is passed onto generation
Distal explanation
-what happened seconds ago
-biopsychosocial model
Proximate explanation
-similarity in structure
Homology
-dont have common ancestors but similar structure
Analogy
-Has designs with purpose that had been passed around generations
-where we came from
-what we got to bring
Ancestral evolution
-where we are now
Current evolution
-has to go to development
Biological preparedness
Is limited because of influence
Free will
Ability to control self (is however limited)
Self control or regulation
Looking for a sexual partner
Mating
Different kinds of Mating
-Polygyny
-Polyandry
-Monogamy
-Promiscuity
-male that mates with multiple partner
-patriarch
Polygyny
-Female that mates with multiple partner
-Monarchy 👑Pol
Polyandry
Only one partner
Monogamy
-group consisting more than both male and female matePr
Promiscuity
How do humans mate?
Monogamous & Polygynous
-Can be found naturally in animals and Humans
Homosexuality
Is naturally presence in mating
Courtship
Gender that is competitive
Male
Gender that is Selective
Female
Gender that have small contribution in reproduction
Male
Gender that have a big contribution in reproduction
Female
Gender that recovers quicker in orgasm
Male
Gender Recovers slowly in orgasm
Female
Gender that cares about quantity
Male
Gender that cares about quality
Female
Gender that values sex than emotion
Males
Gender that values emotion than sex
Female
Gender that gets more affected in sexual infidelity
Male
Gender that gets more affected in emotional infidelity
Female
Gender that looks in body appearance
Males
Gender that looks in more complex traits (Trustworthy, kind, smart etc…) (Bad & Play boy for short term)
Female
-Gives effort but it must be theirs
Parental Uncertainty
-Created sexual jealousy theory
David Buss
-Mate loves someone else
Emotional infidelity
-mate had sex with someone else
Sexual infidelity
-not willing to help when not equal
Injustice
-Will help if certain to be helped back
Reciprocal Theory
Evolutionary psychology brings together two scientific revolutions
John Tooby & Leda Cosmides
-any behavior that increases the survival chance or reproductive capacity of another individual
Helping
-an individual helps another while helping itself
Cooperation
-an individual help another while decreasing its own survival chance or reproductive capacity
Altruism
Developed an Atlas that describes and depicts 6 basic emotional expression
Paul Ekman and Wallace Friesen
6 Basic Emotional expression
-surprise
-Fear
-disgust
-anger
-happiness
-sadness
-Altruistic cam about through natural selection because it prefer initially helps close relatives, who are genetically most similar to the helper
Kin selection theory
A product of evolution
Human mind
-in this theory acts of apparent altruism can asire even among nonkin
Reciprocity theory
-according to this theory, behaviors that seems to be altruistic are actually forms of long term cooperation
Reciprocity theory
Evolutionary psychology brings together two scientific revolutions
John Tooby & Leda Cosmides
-the set of information processing devices, embodied in neural tissue that is responsible for all conscious and non conscious mental activity that generates all behavior and that regulates the body
Mind
Computational theory of mind
Baysian
Computation
Model
About prediction
Baysian
Pattern matching
Computation
Predictive coding
Model
Helps activate or suppress specific coding genes and there by influence the body’s development
Regulatory genes
