cognitive neuroscience |
study of the structure and function of the nervous system and how they influence psychological functions |
|
|
Eysenck's Views |
developed model of personality extraversion (outgoing) vs neutoticism (shy) |
|
|
Extraversion |
Lively, talkative, social |
|
|
Neuroticism |
introverted, mood swings, anxious |
|
|
Esyencks views - cerebral cortex |
differences results from activity in cerebral cortex when cortex is activated, person is alert not activated, drowsy proposed that introverts normally have high cortical arousal than extraverts extraverts seek external simulation to bring arousal up |
|
|
Eysencks views - emotional arousal |
emotional arousal intensifies manifestation of introversion and extroversion neurotics easily stimulated in brains emotion centre |
|
|
BAS |
behavioural approach system Incentive approach system positive emotions based in left pre frontal cortex, linked to dopamine in ventral tegmental pathway |
|
|
BAS hardwiring |
sensitive to rewarding stimuli |
|
|
BIS |
avoidance or inhibitive of punishment or negative outcomes associated with feelings of anxiety |
|
|
Sensation Seeking |
third biological based dimension seeks impulsivity faster drivers, high risk sports, anti-social behaviour, combat units |
|
|
IUSS |
impulsive unsocialised sensation seeking - correlated with disinhibited behaviours, criminality, sexuality, substance use and abuse low IUSS is the capacity to inhibit behaviour in service of social adaption ZUCKERMANN |
|
|
Sensation seeking - hormones |
monoamine oxidase has been linked to sensation seeking serotonin - low levels lead to increased aggression, impulsiveness and less restraint |
|
|
hormones in personality |
androgen - testerone. male sexual hormone, early exposure = male high in males 8-24 weeks gestation, 1-5months after birth, after puberty two sides of brains more interconnected in women than men Berebaum hines 1992 looked at females who were exposed to testerone - played with more boys toys than girls toys than girls who werent exposed |
|
|
hormones in personality - reinisch |
1981 - boys more exposed to androgens at critical stage of development - more likely to resort to violence in conflict resolution |
|
|
testerone and adult personality |
1990 dabbs and morris - men with higher testosterone had more sexual partners, substance abuse, awol in army, assualted others, trouble with other people growing up |
|
|
testosterone |
linked to dominance ◦menwith higher testosterone were less likely to have married◦weremore likely to be divorced if they had married◦Weremore likely to have had extramarital sex and to commit domestic abuse |
|
|
testosterone |
linked to impulsiveness, sensation seeking, dominance can change in response to social situations aggressiveness |
|
|
oxytocin |
oxytocin facilitates approach and pair bonding in humans and animal intranasal, double blind study on 47 heterosexual couples videotaped and cortisol was taken |
|
|
grays motivational systems |
impusivity and anxiety are influenced by two independent motivational systems - BAS and Bis 2 continuums where people could lie as one more than the other |
|
|
loxton and dawe 2011 |
Looked at contribution of trait impulsivity and anxiety in a group of adolescents with high levels of alcohol misuses and disordered eating |
|
|
loxton and dawe 2011 methodology |
BIS and BAS scales (personality) Drive for thinness scale of eating disorders inventory 2 alcohol use disorders identification test (all standardised tests) |
|
|
loxton and dawe 2011 conclusions |
BAS – predictive of alcohol misuse BIS and BAS – predictive ofdysfunctional eatingBAS = All disordered groups higherthan non-disordered BIS = Dysfunctional eating girls,with or without alcohol misuse higher than alcohol misusing only girls |
