- Observational design
- Unstructured observation - records all relevant behaviour but has no system, for example noting what people do as they tackle a difficult exam question. This might be used if no research has been conducted before as a kind of pilot study to see the kinds of behaviours that might be recorded using a structured system.
- A problem with this could be that there might be too much to record. Also the behaviours recorded will be the most visible or eye-catching to the observer but not necessarily the most important behaviours.
- Structured observations
- Systems of organise observations to make them more objective and rigorous. The main ways of structuring observations are:
- Untitled
- Behavioural categories - Dividing a target behaviour such as stress of aggression into a subset of specific and operationalised behaviours, for example infant behaviour into a list of smiling, crying, sleeping, etc. These categories should be objective, cover all possible component behaviours and be mutually exclusive.
- Sampling procedures - selecting behaviours. They are often used when there are too many behaviours to record. There's event sampling - counting the number of times a certain behaviour occurs in an individual, like how many times someone smiles in a 10-minute interval. There's also time sampling - recording behaviours in a given time frame, like noting what the individual does every 30 seconds, ticking one or more categories from a checklist.
