- Bio + Behavioural perspectives of P and I
- Early bio thoughts
- Physiognomy (endo, meso, ectomorph)
- 'Humours': Socrates sanguine, choleric (bodily fluid of blood, black bile, phlegm etc)
- Evolutionary P psychology
- Natural Selection (Darwin)
- Adaptive strategies for survival (fearfulness, impulsivity, social)
- Molecular Genetics
- specific genes that influence behaviour (MAOA)
- Genes and intelligence
- DTNBP1 (UCLA 2006)
- associated with SZ but may also link to general cognitive ability
- Plomin 2007
- 6 genes strongly associated with high/low IQ
- BUT even most powerful only accounted for .4% of variation in IQ between people
- 6 genes strongly associated with high/low IQ
- Plomin 1998
- IGF2 gene twice as common in highly intelligent kids
- DTNBP1 (UCLA 2006)
- Genes and personality
- Gene that produces DRD4 associated with ADHD and novelty-seeking behaviour
- "Prozac gene" produces neurotransmitter related to serotonin
- Linked to neuroticism + anxiety-related traits
- Although gene accounts for 1/2% of variance (Harmer 2002)
- ASPD
- Low levels of activity in frontal lobe when lying
- linked with low serotonin
- So low regulation of aggression and impulsivity
- Behaviourism
- Pavlov, Watson, Skinner
- Dogs, Little albert, operant condit-rats
- Learnt behaviour
- Conditioning
- Tabula rasa, nurture, experience, environmental influence
- Personality = product of learned associations
- Pavlov, Watson, Skinner
- Physiology and body chemistry
- Cortical arousal theory (Eysenck 1985)
- Bio basis for certain P types (E and N)
- EEG measures arousal from RAS (Sympathetic part of ANS)
- I's = assumed innate higher levels of arousal
- I's = higher amplification of input than E's
- Inverted U graph shape for arousal/performance
- Intermediate levels of arousal give "positive hedonic tone"
- Campbell and Hawley 1982
- student study habits: E's low level of stimulation, high boredom
- I's = assumed innate higher levels of arousal
- EEG measures arousal from RAS (Sympathetic part of ANS)
- Bio basis for certain P types (E and N)
- Gray Reinforcement Sensitivity theory 1964
- Behavioural activation system (BAS)
- Motivation to get rewards
- More active in E's
- Motivation to get rewards
- Behavioural inhibition system
- Motivation to escape
- More active in N's
- Motivation to escape
- Behavioural activation system (BAS)
- Cortical arousal theory (Eysenck 1985)
- Early bio thoughts
