Lecture 11 Flashcards
1
Q
Evolutionary explanation for personality
A
- Cross cultural data: structure of traits appears universal
- Cross species data: “correlated suites of behaviour’, analogues of big five found in non-human animals
- Behavioural genetics: genetic variation, reflects evolutionary forces (domestication of dog)
- Environment of evolutionary adaptedness
- adaptive traits survival/reproduction?
- Selective Neutrality: fitness-neutral genetic mutations
Balancing selection –> - Antagonistic Pleiotropy: fitness trade offs
- Environmental Heterogeneity: different for different things
- Frequency dependent selection
2
Q
Life history theory is?
A
1) Resources vary in their availability over time and space
2) fitness maximisation is not a one-shot game
3) trade offs must be made (energy out/energy in)
3
Q
What is the candidate gene approach
A
Identify relevant genes from theory
Challenges: identifying relevant genes
detecting reliable and replicable genetic effects
4
Q
Genome-wide association studies (GWAS)
A
entire genome scanned for associations with given trait
5
Q
Methods for exploring brain structure and function on personality
A
- psychopharmacology
- MRI
- EEG
6
Q
personality is
A
regularities in behaviour and experience
