Biopsych PEELs

Question 1

Flight or fight

Answer 1

P Fight or flight is reductionist
E
E
L
P gender differences
E women tend and befriend yet men flight or fight
E they have to protect the young, oxytocin amplified by oestrogen in women
L Alpha bias to assume only men fight or flight, in stress, men look to others for social support
P outdated explanation
E in modern times streesors are more long term than they used to be
E ignores role of cognition to deal with modern stressors
L still use fof but it will devolve as creates health problems

Question 2

Localisation

Answer 2

P research support for Broca’s area being localised
E tan tan lesion in Broca’s area
E Broca’s is localised for speech production
L just a case study
P gender differences
E women have a bigger Broca’s and wernicks area than men
E argues localisation isn’t innate, may be plasticity
L doesn’t diss localisation just that localisation is diff to each person
P brain only localised for simple things
E higher mental functioning cannot be localised and uses multiple brain areas
E more important to look at how they work together
L fMRI scans can aid this theory

Question 3

Localisation

Answer 3

P research support for Broca’s area being localised
E tan tan lesion in Broca’s area
E Broca’s is localised for speech production
L just a case study
P gender differences
E women have a bigger Broca’s and wernicks area than men
E argues localisation isn’t innate, may be plasticity
L doesn’t diss localisation just that localisation is diff to each person
P brain only local
E
E
L

Question 4

Lateralisation

Answer 4

P scientific
E lots of controls (sperry))
E strong causation
L case studies
P support
E chickens have food hemi and predator hemi
E evolution for survival
L but humans aren’t prey
P changes with age
E becomes delateralised by 25
E due to more life experiences both take on functions recruitment of homo areas
L starts a lateralised so not sure if decay or experience causes

Question 5

Plasticity

Answer 5

P bad - maguires sample
E androcentric and no before test
E don’t know if same in women or maybe the taxi men’s posterior hippo was already big
P did futrther research to stop this problem
E ev shows hippo did increase form before
E learning the map actually changed the structure of their brain
P indivisible differences
E gender- fomen more brocas and wernickes education- undergradste had more plasticity than no education age- 40 yes less ability to plasticity
E shows it’s environmental and biological

Question 6

Circadian rhysthms

Answer 6

P support EP
E chipmunks SCN removed sleep wake cycle stopped, eaten by weasles
E Ep is responsible for circ rhythms
L humans are apex we don’t really need it for survival so maybe
P EP is important
E cave man no EZ only EP still had circ rhythm
E EP more important
L case study
P real life imp for EP
E eskimos have dark all winter and light all summer but still have 24
E proves just need EP
L but they did have blackout blinds and lights etc so EZ

Question 8

Ultradium rhythms

Answer 8

P ultra rhythms are controlled by EP
E wood by door bell every time EGG waves changes, only remember dreams in REM not not REM
E SCN regulates rest activity cycles, bio controlled
L small sample size of 9

Question 9

Infradium cycle

Answer 9

P research supports infra cycles controlled by EZ
E collected pheromones from sweat (EZ) due to ovulate, put on upper lip of women and their cycle synced to the donor
E EZ do play a role as mental cycle changed
L could just be evolution, not as useful now
