Observations Flashcards
What are observations?
Observations often form the starting point for any research in Psychology; we need to observe that people forget before we can study forgetting, we might watch children at play before embarking on research into the purpose of their play.
When using the observational method psychologists simply observe in real life situations or in the laboratory without manipulating an independent variable. THIS CAN BE EXTREMELY USEFUL WHEN IT IS NOT POSSIBLE TO MANIPULATE VARIABLES DUE TO ETHICAL OR PRACTICAL PROBLEMS OR SIMPLY AS A STARTING POINT FOR RESEARCH. Observations usually involve the categorisation or rating of behaviour in precise ways. The emphasis is placed on how people or non-human animals behave in specific situations; no attempt is made to influence the behaviour being investigated in any way.
Observations can differ in several important ways, depending on:
- The setting in which it is carried out (naturalistic vs. controlled)
- The role of the researcher (participant or non participant)
- The awareness of the participants involved (covert or overt observation)
- The amount of structure that is Imposed (structured or unstructured)
- Time or Event Sampling
- Inter-observer reliability
The study setting
- Observational studies are often carried out in a natural setting such as school, canteen or social area. Studies that focus on people’s naturally occurring behaviour are often referred to as naturalistic observations.
- Observational research can also be conducted in a laboratory which allows the researcher more control over the environmental in which the research is carried out. For example, Labs can be designed to resemble playrooms, once children have become completely accustomed to such a room, their behaviour may be observed through a one way mirror. These are mainly referred to as controlled observations.
The Role of the Researcher
A distinction is often made between participant observation, in which the observer actually joins the group of people being studied and non-participant observation, in which the observer remains external to those being observed. In participant observations the researcher may be most interested in trying to understand the meaning of the behaviours they are observing, in which case they typically produce detailed verbal qualitative descriptions of the behaviour they observe. Observers also have to decide whether to remain covert or overt. In overt observations the participants are made aware of the research that is taking place, therefore enabling it to be more ethical, or in covert observations they remain unaware that the research is taking place.
The structure of an observation
-The amount of structure in an observation will differ. To conduct an observation it is necessary to decide how the data will be recorded.
Unstructured observation
Unstructured observations can be conducted with the researcher simply writing down everything he or she observes and analysing it later by looking for patterns in the information that has been recorded. This is very useful if you are studying something for the first time and mainly produces qualitative data. This type of observation may lead you to generate hypotheses that could be investigated experimentally or suggest more structured observations that could be conducted. One problem with unstructured observations is that the behaviour recorded will often be those which are most visible or eye-catching to the observer but these may not necessarily be the most important or relevant behaviours.
Structured observations
The observer using a coding system/scheme in order to count the number of times specific behaviours occur. Behavioural categories are needed so that observer can count the number of times that each behavioural category occurs during a given period of time. This kind of approach produces quantitative data that can be analysed statistically. In order to record systematically, behaviours to be observed must be operationalised defined and measurable. Operationalisation involves breaking down the behaviour being studied into a set of components.
Strengths of controlled observations
-High levels of reliability
This is because of the high levels of control over the environment meaning that the observations can be replicated and findings confirmed or challenged.
Weaknesses of controlled observations
-Likely to have lower ecological validity
This is because they are potentially more artificial due to controlled nature and so may not generalise to real life behaviour.
Strengths of naturalistic observations
-High in ecological validity
This is because they are conducted in real life setting observing natural behaviour so more generalizable to real life behaviour
Weaknesses of naturalistic observations
-More potential for confounding variables to effect the results
This is because of the lack of controls over the situation participants are observed in.
Strengths of participant observations
-Allows observer to gather more detailed accounts due to flexibility.
This is because the observer is involved in the events they are observing so the researchers are more likely to get accurate data.
Weaknesses of participant observations
-May be a potential for observer bias as it is harder to remain objective.
This is because the observer is involved in what they are observing and so may find it difficult to remain detached.
Strengths of non-participant observations
-Reduces the effect of the observer on the participants behaviour.
This is because the observer does not interact with participants with participants so has no effect on behaviour.
Weaknesses of non-participant observations
-The observer may miss vital information
This is because the behaviour may be shown while the observer is making notes
