FIGHT OR FLIGHT
AO1
• endocrine + NS act together to deal with stressor
• sense organs perceive stressor
• Hypothalamus stimulates SNS + msg to pit gland
• Secretes ACTH into blood stream
• Msg to adrenal medulla
• Release of adrenaline into bloodstream (activates SNS)
• Bodily arousal: inc breathing , sweating, shaky hands
• inc HR - more o2 to muscles for movement
• Dilates bronchi - more gas exchange more O2 for aerobic resp
• Decreases digestion (vasoconstriction) - highest volume of blood w/ O2 sent to skeletal muscles + brain
• once no longer exposed to stressor body returned to normal by PNS
AO3
S: HIGHLY SCIENTIFIC
• objective empirical evidence
• Levels of hormones - cannot be affected by social desirability bias
W: HIGHLY RED
• complex psychological behaviour down to simple comp
• Hypothalamus and hormones
• Overlook, important psychological and emotional factors
W: BETA BIAS
• reduces gender differences and stress response
• TAYLOR - tend + befriend
S: PRAC APPL
• understanding negative effects of stress - heart disease + immune system weakened
• More aware - workplace strategies
• Motivate ppl live in healthy way

AO1
Each part of the brain carries out a specific function
• motor cortex - voluntary muscle movements
• Rear of frontal lobe
• Damage may become paralysed and find motor control lost on opposite side of body
• Broca's area - speech production
• frontal lobe , left hem
• Damage - diff speaking full fluent set
• wernicke's area - lang comprehension
• Temp lobe most left hem
• Damage - speak fluently but meaningless
• auditory cortex - auditory info
• Temp lobe
• damage - gearing loss
AO3
S: BROCA + WERKICKE
• post-mortems
• Damage to part area in - led to inability to -
S: HIGHLY SCIENTIFIC
• empr objective methods
• Post - mortems , brain scans
W: LANG LOC QUESTIONED
• Only 2% of modern researchers
• FMRI - lang holistically dist - lang streams
W: PLASTICITY
• MAGUIRE - brain function can develop and change depending on environment
