DGD
1 of 48
- assumptions
sdg
2 of 48
suggests everythign psychological is first?
biological
3 of 48
so to fully understand behaviour we must look to which two things?
biological structures / bodily processes
4 of 48
an understanding of what can explain thoughts and behaviour?
brain structure and function
5 of 48
mind lives in the brain meaning?
all thoughts / feelings / behaviour ultimately have physical basis
6 of 48
this is in contrast to cognitive approach that sees?
mental processes separate from physical brain
7 of 48
- genetic basis of behaviour
dfg
8 of 48
geneticists study what about behaviour?
whether its inherited in the same way as physical characteristics
9 of 48
what are used to determine likelihood of trait's genetic basis?
twin studies
10 of 48
by comparing what between DZ / MZ twins?
concordance rates
11 of 48
- genotype and phenotype
dfgd
12 of 48
what is a genotype?
actual genetic makeup
13 of 48
whereas phenotype?
way genes are expressed through physical / behavioural / psych characteristics
14 of 48
expression of genotype is inevitable influenced by?
environmental factors
15 of 48
illustrates much of human behaviour depends upon what?
interaction of nature ad nurture
16 of 48
- evolution and behaviour
dfg
17 of 48
what is darwin's theory?
natural selection
18 of 48
the principle of this theory is that what will continue in future generations?
any genetically determined behaviour that enhances individuals survival / reproduction
19 of 48
why does the selection occur in nature?
bc some traits give possessor certain advantages
20 of 48
EVALUATION
F
21 of 48
:) scientific methods of investigation
dfg
22 of 48
include scanning techniques like?
fMRI / EEG
23 of 48
as well as what kind of studies?
family / twin
24 of 48
and trials?
drug trials
25 of 48
with advances in tech its possible to accurately measure what kind of processes unbiasedly?
bio / neural
26 of 48
this means bio approach is based on?
reliable data
27 of 48
:) real-life application
dfgd
28 of 48
increased understanding of biochem processes in brain has led to dev of?
psychoactive drugs
29 of 48
that treat serious mental illnesses like?
depression
30 of 48
are these drugs effective for all patients?
no
31 of 48
this is a strength because means sufferers are able to manage condt and?
live relatively normal life
32 of 48
:( causal conclusions
dfg
33 of 48
bio approach offers exps for mental illnesses in terms of?
neurotransmitter actions in the brain
34 of 48
this evidence for this relationshiop come from studies showing what about certain drugs?
they reduce symptoms of a mental disorder
35 of 48
and therefore its assumed what about the neurochemical in the drug?
causes the disorder
36 of 48
discovering association though does not mean?
its a cause
37 of 48
this is a limitation bc the bio approach is claiming to have discovered causes when?
only association exists
38 of 48
EVAL EXTRA
DFG
39 of 48
:( deterministic view of behaviour
sdg
40 of 48
determinist bc sees all human behaviour governed by?
internal biological causes
41 of 48
this has wider implications for legal system why?
bc one of laws is offenders seen legaly and morally responsible for actions
42 of 48
:( cannot separate nature and nurture
dfg
43 of 48
what is the important confounding variable in twin studies?
all in same family are also exposed to similar environmental conditions
44 of 48
this means findings could just as easily be interpreted to support?
nurture > nature
45 of 48
this approach aso has difficulty accounting for the fact in rsrch studies what about DZ?
they have higher concordance rates than pairs of ordinary siblings
46 of 48
how can nurture explain this?
not only 50% DNA but also grew up in same place @ same time which influences
47 of 48
which points towards?
interactionist approach
