The four articles we don't learn anywhere else Flashcards
What did Darwin think were the two functions of emotion expression?
- Preparing the organism to respond adaptively to environmentally recurrent stimuli.
- Communicating social information.
What are the two stage model of emotion-expression evolution?
It is a emotion-expression model with the two functions: adaption (emotion expressions for physiological regulation) and exaptation (emotion expressions for social communication).
What is “adaption” in the two stage model of emotion-expression evolution?
For example, that the widened eyes of individuals instructed to pose a fearful facial expression were found to increase the scope of their visual field and the speed of their eye movements, allowing expressers to better identify objects in the periphery.
What is “exaptation” in the two stage model of emotion-expression evolution?
Emotion expressions began as cues – providing information about internal states but not existing for that reason – but eventually transformed, in both form and function, to become signals.
What is the first law of behavior genetics?
All human behavioral traits are heritable.
What is the second law of behavior genetics?
The effect of being raised in the same family is smaller than the effect of genes
What is the third law of behavior genetics?
A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families.
What is behavior genetics the study of?
The study of the manner in which genetic variation affects physiological phenotypes (traits).
What is the fourth law of behavior genetics?
A typical human behavioral trait is associated with very many genetic variants, each of which accounts for a very small percentage of the behavioral variability.
What does a stronger relationship between genetic and phenotypic similarity imply?
A greater influence of the measured SNPs on the trait of interest.
What does “population stratification” mean?
If a SNP is more common in individuals of a certain ancestry or region, then it may falsely appear that the SNP is associated with a trait when the trait is actually associated with a pattern of ancestry or region of origin.
Is there one gene that are for one complex trait or another?
NO! Most genetic variability in behaviour between individuals is attributable to genetic differences that are each
responsible for very small behavioral differences.
What is politics designed to solve?
The coordination problems that emerge from group living.
What are stronger males more likely to do in politics?
Stronger males are more likely to solve international conflicts of interests with war, more likely to advocate for policies that favor their own group, and more likely to support policies that are aligned with their economic self-interest.
What is the key tool for political power?
To form and join coalitions (alliance) with others.
