1.1 Research methods and techniques Flashcards
What is a laboratory experiment?
An experiment conducted under highly controlled conditions to investigate the effect that the change of an IV has on the DV
What is a field experiment?
An experiment carried out in the everyday environment of the participants. The experimenter still manipulates the IV and tests the effect on the DV, but the research has no control over extraneous variables
What is a quasi experiment?
Research has no control over the IV, but instead must choose a naturally occurring variable and test the effect on the DV. Artificial or natural setting
What is the difference between a naturalistic and controlled observation?
In a naturalistic observation, a participant’s behaviour is studied in a natural environment. In a controlled observation, they are observed in a controlled environment, such as a laboratory.
What is the difference between an overt and covert observation?
In an overt observation, the participants know that they are being observed, whereas in a covert observation, they do not know
What is the difference between a participant and non-participant observation?
In a participant observation, the observer takes part in the experiment. In a non-participant observation, the researcher observes without participating in the experiment itself
What is the difference between a structured and unstructured observation?
An unstructured observation generates descriptions (qualitative data). Structured generates quantitative data as the observation focuses on categorised behaviours from a coding scheme.
What are features of a good coding scheme?
- Objective and clear
- Cover all possibilities
- No overlapping categories
What is event sampling and what are its strengths?
Observations of how many times a particular event happens.
- Good for when behaviours are not frequent
- Less likely to miss behaviour
What is time sampling and what are its strengths?
Set time intervals that the observation takes place with breaks.
- Increases concentration
- Allows time to record data
What are the two main types of self report?
Interviews (verbal) and questionnaires (written)
Structured interview
Each interview is presented with exactly the same questions in the same order and the researcher aims to obtain quantitative data
Unstructured interview
Questions in this style of interview are not prearranged. The data obtained from this style of interview is usually qualitative
Open ended questions
Questions which obtain qualitative data by asking questions which cannot be answered with just one word. Meaningful answers with rich data.
Closed ended questions
Can be answered with just one word like yes or no. Easy to answer and score.
