When a target behaviour is broken up into components that are observable and measurable
Event Sampling
A target behaviour or event is first established then the researcher records this event every time it occurs
Time Sampling
A target individual or group is first established then the researcher records their behaviour in a fixed time frame e.g every 60 seconds
Whyareobservationalcategoriesused?
There may be too much going on in a single observation for the researcher to record it all
It is necessary to simplify the target behaviours that will become the main focus of the investigation using behavioural categories
This is a structured observation
Examples of observational categories
It is necessary to break the target behaviour up into a set of behavioural categories that should be precisely defined and made observable and measurable
For instance, the target behaviour ‘affection’ may be broken down into observational categories such as hugging, kissing, smiling and holding hands
Each of these behaviours must be observable
Inter-observerreliability
Researchers should not conduct observational studies alone as single observers may miss important details or may only notice events that confirm their opinions or hypothesis
This introduces bias into the research process
To make data recording more objective and unbiased, observations should be carried out by at least two researchers and data from observers are compared to check for consistency e.g reliability
How do you carry out inter-observer reliability?
Observers should familiarise themselves with the behavioural categories to be used
They then observe the same behaviour at the same time
Observers should compare the data they have recorded and discuss any differences in interpretations
Observers should analyse the data from the study
Inter-observer reliability is calculated by correlating each pair of observations made and an overall figure is produced
AO3 Behavioural Categories: Structured and Unstructured Observations
Structured observations that involve the use of behavioural categories make the recording of data easier and more systematic
The data produced is likely to be numerical so analysing and comparing the behaviour observed between participants is more straightforward
Unstructured observations tend to produce qualitative data which may be more difficult to record and analyse but they benefit from more richness and depth of detail in the data collected
AO3 Behavioural Categories
Although the use of behavioural categories can make data collection more structured and objective, it is important that such categories are as clear and unambiguous as possible
They must be observable, measurable and self-evident
Researchers should also ensure that all possible forms of the target behaviour are included in the checklist
Categories should be exclusive and not overlap
The difference between ‘smiling’ and ‘grinning’ would be very difficult to discern
AO3 Behavioural Categories: Sampling Methods
Event sampling is useful when the target behaviour or event happens quite infrequently and could be missed if time sampling was used
If the specified event is too complex the observer may overlook important details if using event sampling
Time sampling is effective in reducing the number of observations that have to be made
Those instances when behaviour is sampled might be unrepresentative of the observation as a whole
