Advantages of using scientific methods in psychology

?
What is the first advantage of using scientific method is that the findings are high on?
reliability
1 of 30
What happens if the research is repeated?
the same findings should occur, due to standardized procedures and environments
2 of 30
For example, what was Milgram's obedience research show?
It has been repeated many times
3 of 30
What did the results consistenty show?
65% of people obey authority figures
4 of 30
Therefore, using scientific methods is beneficial why?
because the findings will be consistent and replicable
5 of 30
In addition, scientific methods can be what?
high on internal validity
6 of 30
What is used?
standardised, double blind procedures in scientific methods
7 of 30
What is minimised?
researcher bias
8 of 30
For example, In Buss' study what didnt the pps or native researchers know about?
5 hidden characteristics that were being evaluated
9 of 30
Why?
so no clues could have been given to pps and demand characteristics would have been reduced
10 of 30
Thus using a scientific method which what?
tests what it aims to test, making findings beneficial
11 of 30
The second advantage is the findings are high on?
Objectivity
12 of 30
Why ?
The scientific method involves control of confounding variables, often in lab conditions
13 of 30
For example, Loftus and Palmer were what?
able to indentify the effect of a ver on their pps estimations of speed in a lab
14 of 30

This meant that they could objectively question what?
reliability of eye witness testimony, revolutionising the justice system

What does this use?
scientific method is beneficial because cause and effect can be established leading to applications

What is the third advantage?
scientific methods produce quantified data in the form of numebrs and statistics.
18 of 30

reductionist and deterministic
23 of 30

positives
24 of 30
This si because scientists believe that the best explanations of behaviour are what?
the simplist
25 of 30
as in?
Occams razor
26 of 30
Scientists also favour explanations which are?
deterministic
27 of 30
Because they like to know what?
the causes of behaviour which can then be predicted and controled
28 of 30
What did Rahe's research with sailors conclude?
illness is positively correlated with stressful life events rather than other factors which is both reductionist and deterministic and therefore good science
29 of 30
Thus information from these scientific methods could be?
useful through practical applications
