HideShow resource information
What is the first disadvantage of using scientific methods?
the findings will be low on external validity
1 of 39
Why?
scientific methods often involve studying pps in artificial surroundings, such as a lab
2 of 39
For example, What was Asch's findings on conformity?
not a reflection of real life
3 of 39
In addition, scientific findings lack what?
historical validity

not conform to the majority
6 of 39
nor may they do what?
in a work or school environment with friends rather than strnagers
7 of 39
Thus weakening what?
the use of scientific methods as they don not paint a picture of real life
8 of 39
What is the second disadvantage of research?
they are inevitably subjective
9 of 39
why?
the experimenter and pps are both human, and thus research is a social process
10 of 39
Why does this mean it is difficult to be objective?
in psychological research and experimenter bias and demand characteristics are inevitable
11 of 39
REsearchers want to collect data that will what?
support their hypothesis
12 of 39
and pps want to be?
'good pps to please the researcher
13 of 39
For example, Rosenthal founf out what?
his psychology students results in the rat maze study supported the hypotheses they were given to test
14 of 39
Rats labelled as 'bright' what?
out performed the 'dull rats' in the T maze task
15 of 39
What happened in reality?
labels were randomly assigned
16 of 39
thus scientific methods although seemingly reliable, might contain what?
bias weakening arguments for their use
17 of 39
It could also be argued that many scientific methods in psychology use what?
animals
18 of 39
This is more scientific than research on?
humans
19 of 39
Why?
due to the additional control over upbringing
20 of 39
Studies using animals are?
biased
21 of 39
Why?
the way that the experiments are designed and the interpretation of data can be manipulated by the researcher
22 of 39
because?
animals are unable to communicate and hence findings are often only 'the best guest'
23 of 39
In addition it is hard to?
generalise results from animals to humans and hence the use of more scientific methods might be detrimental to applications
24 of 39
The third disadvantage is that scientific methods?
ignore the personal view of the pp
25 of 39
For example?
the feelings and opinions that make us human
26 of 39

is that it produces findings which are reductionist and deterministic
34 of 39
From a non scientific view point what are these characteristics?
negative
35 of 39
Why?
if the findings are reductionist (Rahe's conclusion that stress and illness are positively correlated with previous life events
36 of 39
they are what?
oversimplified
37 of 39
Which is not?
appropriate when explaining complex behaviour such as stresss and illness
