Chapter 2 Flashcards
Behavioural Genetics
This field understands what influences genetics have on the characteristics and behaviours within a population
Evolutionary Psychology
This field looks at how natural selection shapes influences mental processes and behaviours
The Juke Family
People who grow up in the same family or community share common traits
Gene and Environment Interactions
Nature vs Nurture
Meta-Analysis
Environment influences your brain chemistry
Diathesis
A genetic vulnerability or predisposition to develop a psychopathological condition
Just because you have a genetic condition doesn’t mean you will get a specific condition
Differential Susceptibility model
Individuals exhibit gene-based differences in their sensitivity or reactivity to the environment
People are environmentally sensitive to both adverse and favourable conditions
Natural Selection
The different survival and reproduction of living things with genetic characteristics that allow them to take advantage of their environment
Adaption
Any characteristic or trait through natural selection that increases the survival or reproductive success of a species
for example cheetah has speed
Psychological Adaptions
Preferences, Values, emotions, or temperaments
for example taste
They are NOT consciously motivated
The environment of evolutionary adaptiveness
The set of conditions that existed during ancestorial time sand to which the human body and brain adapted
Selfishness
Selfishness
- Acting in ways that increase the chances of your own survival and reproductive success at the cost of someone else’s
two-spotted Astyanax
The Cinderella Effect
Children are at greater risk to be killed by a step-parent rather than their biological parent
Cooperative Behaviour
Helping non-genetically related individuals will be adaptively provided the recipient returns the favour
for example, vampire bats cough up food to feed less fortunate bats
Reciprocal Cooperation
An evolutionary adaptive behaviour that involves providing a non-related individual a benefit on the basis that they will return the favour and thereby increase survival and reproductive success
Cheater Theory
Antisocial and criminal behaviour stems from low parenting effort and high mating effort reproductive strategies favoured by some men
