Research Methods

 

Last week, we looked briefly at different types of data that psychologists might be interested in - behaviour, inner experiences, material data and symbolic data. This week, we will look in more detail at the research process and commonly used psychological research methods. We will continue to explore research methods throughout the unit, as we look at different examples of research in the area of gender development.

 

 

Experiment - if you were asked to think about research methods in psychology, the chances are that you would think of 'experiments' first. An experiment aims to measure cause and effect, by measuring the effect of the independent variable on the dependent variable.

 

Look at the simple example given below and discuss the questions in pairs or small groups:

 

A psychologist wishes to test the effect that drinking alcohol has on students' co-ordination skills. She provides one group of students with 10 vodka shots and a second group of students with 10 'placebo' vodka shots (i.e. water). The students then play a video game based on co-ordination skills, and their scores are recorded and compared.

 

  1. What was the independent variable in this experiment? (the variable that the experimenter changed?)
  2. What was the dependent variable? (measured for a change)
  3. Why did the experimenter give 'water shots' to some students? Why was it important that the students didn't know which group they were in?
  4. What other factors might have affected this particular experiment?

 

 


Observation Studies

 

One frequent criticism of experimental studies is that they are lacking in ecological validity - they may 'prove' something in the lab, but it doesn't count for much in the real world.

 

Using the example above, of the effects of alcohol, some psychologists would argue that we would get much more realistic data if we were to study the participants in real life - in a real pub, for example.

 

Observation studies involve more than just sitting back and watching the world go by, however. Information must be carefully recorded, often by more than one researcher. There are a number of ethical concerns - such as consent - and the researcher must also decide whether to declare their presence, i.e. whether to conduct an overt or covert observation. In some cases, the researcher may decide to join in with a group's activities, in a participant observation (although this may not be the best idea in the pub), or may simply watch, in a non-participant observation.

 

 

Interviews, surveys and questionnaires

 

These are research methods which are probably already familiar to you - you will undoubtedly have had job, college or medical interviews at one time or another, and you will probably also have completed market research surveys and questionnaires.

 

Psychological interviews are carried out with a rather different purpose to most job interviews - they aim to gain an insight into an individual's inner experiences.

 

Interviews may be highly structured (all of the questions are determined in advance, and may have restricted or closed responses, such as questionnaires); semi-structured, with topic areas defined in advance, but some flexibility for follow-up questions, or unstructured, and led by the interviewee.

 

Look at the sample questionnaire provided. Can you find any potential problems with it?

 

 

Case Studies

 

We looked at a famous case study, of Freud's and Breuer's patient Anna O, last week. A case study can be a useful research method when psychologists wish to examine one individual's situation in more detail, for example, when presented with a client such as Anna O who displays particularly unusual symptoms. Case studies may also involve small groups, such as families, or one-off events. A case study may combine different types of data to explore an individual's situation in depth.

These cover most of the major psychological methods, however there are others used primarily by qualitative psychologists, which includes many feminist researchers.
