Personality Flashcards
personality definition
interindividual differences in behaviorua tendences consistent over time (repeated) and context (stable)
“a flexible phenotype”
ways of organizing personalities
big 5 (ocean)
helen fisher hormone
shy/bold or extravrersion/ntraversion
learning speed and coping style
big 5
OCEAN:
opennes
conscientiousness
extroversted
agreeableness
neurotic
helen fisher hormone
Dopamine: explorers (pleaure activation)
Seratonin: builders (behavioural inhibition)
Testosterone; ‘directors’ ; behavioural persistences
Estrogen: ‘negotiators’ behavioural dependnece
measuring personality in animal methods
- RATING: cumulative and naturalistic; relates to expert familliarity (better in ozoos; non objective) i.e. big 5 10 item personality test
- CODING: ethological and behaviioural (But slow, direct obs. naturalistic setting, objective)
critique of big 5 measures
subjective
lacks repeatabillity and consistency
top down
restrictive
has circular reasoning
how does behavioural observation measure personality
looks at:
- general activity
- positive affects
- sociabillity/aggression/tolerance
- anxiety
- groomign equity
- exploration perssitence; novely
= boldness; shyness
= tool usage
describe shy personalities
REACTIVE
high latency
low aggression
less active, explorative, risk taking and routine driven
more plasticity
adaptive to environment
describe bold personalities
PROACTIVE
low latency
aggressive
active explorative risk-taking
routine driven
less plasticity
control environment
how does personality impact learning?
speed of learning & discrimination abillity
example: shy fish are better learners
how does personality impact coping style
shy; higher cortitestosterone
bold; higher adrenaline
coping style= in stressful situations, figtht or flight reactions and sensitivity
how does individual behaviour and personality relate
physiology
genotype—> development—> environment–> personality—> behaviour etc.
epigentic impacts
fitness model?
personalityh impacts your fitness; in your abillity to survive (predator avoidance, group living) and reproduce (dominance/submissive, parental style etc)
shy= risk averse
extraversion= might impact your surviviabillity; i.e. gorilla captive settings decline
why DOES extraversion mantain?
relates to game theory and ESS:
frequency-dependent vs fluctuating environments
i.e. DOVE vs HAWK + population based circumstances
if intense competition; females are slower and males are faster
if less competition: females faster and males slower
chimp friendships…
impacted by compativllity in personality (massen et al )
