Disadvantages of using scientific methods in psychology

HideShow resource information
What is the first disadvantage of using scientific methods?
findings will be low on external validity
1 of 33
Why is this?
because scientific methods often involve studying pps in artifical surroundings,such as lab
2 of 33
For example?
Asch's findings on conformity were not a reflection of real life
3 of 33
In addition scientific methods also lack?
historical validity
4 of 33
as they are a reflection
5 of 33
What is this case?
of 1950's AMerica during the era of McCarthyism of one specific time
6 of 33
If the task was completed today pps might not what?
conform to the majority, nor may they do so in a work or school environment with friends rather than strangers
7 of 33
thus weakenning?
the use of scientific method as they do not paint a true picture
8 of 33
What is the second disadvantage of scientific methods?
the findings of research are inevitably subjective because the experimenter and pps are both human and this research is a social process
9 of 33
This means it is difficult to be objective in what?
psychological research and experimenter bias and demand characteristics are inevitable
10 of 33
What do researchers want to collect?
data that will support their hypothesis, and pps want to be good participants to please the researcher
11 of 33
For example?
Rosenthal found that his psychology students' results in that rat maze study
12 of 33
What did he support?
the hypotheses they were given to test
13 of 33
What were rats labbeled as? and how did they perform?
'bright' outperformed the 'dull' rats in the t-maze task
14 of 33
When in reality what was randomly assigned?
15 of 33
This suggests what?
seemingly reliable, might well contain bias weakening arguments for there use
16 of 33
It could also be argued that?
many scinetific methods in psychology use animals
17 of 33
What is this?
more scientific than research on humans due to the additional control over upbringing
18 of 33
studies using animals are biased
19 of 33
The way that experiments are designed and interpretation of data can be?
manioulated by the researcher, as animals are unable to communicate and hence findings are often only best guess
20 of 33
In addition it is hard to what?
generalise results from anima,s to humans and hence the use of more scinetific methods might be determental to applications
21 of 33
What is the fourth advantage?
scientific methods ignore the personal view of the pp
22 of 33
for example?
the feelings and opinions that make us human
23 of 33
BEcause science aims to be what?
quantative, it sees no place for qualitative words and language - yet this is the form in whcih people portray the feeling and values that make them human
24 of 33
For example, what are the findings of buss?
study of mate preference were purely quantitative
25 of 33
What does this mean?
pps were not able to give their own personal views on mating and dating. they could only answer the questions on the questionaire given the responses available
26 of 33
What does this suggest?
the results of scinetific methods do not allow for personalised outcomes
27 of 33
What is the last disadvantage?
produces findings which are reductionist and deterministic
28 of 33
From a non -scientific point of view what are these characterists?
29 of 33
this is becauses findings are reductionist
30 of 33
as in what?
Rahe's conclusions that stress and illness are positively correlated with previous life events
31 of 33
They are>
oversimplified which is not appropriate when explaining complex behaviour such as stress and illness
32 of 33
What are non -scientists?
are also not keen on deterministic explanations as they neglect the importance of free will and individual differences
