Observations: recording behaviour consistently
Compare structured and unstructured observation and apply operationalised behaviour categories, tally charts and overt or covert roles.
Section Paper 2 · Paper 2 · Topics 4–6 and non-experimental methods
Original teaching mapped to Cambridge IGCSE Psychology 0266 Version 3 for 2027–2029. The course is independent study support, not Cambridge material, an official mark scheme or an awarded grade. Named-study notes summarise the required findings; candidates are not expected to evaluate named studies. Self-check practice is not official grading, a timed Paper 1/2 simulator or teacher review.
Before you begin
- Use the Version 3 syllabus and confirm availability in your administrative zone with Cambridge and your school. Both papers are compulsory. The updated named-study summaries are required context; full original research articles are not required.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Before observations: recording behaviour consistently, which approach is most useful?
What you will learn
- Describe observation as watching participants to collect data
- Compare structured and unstructured observation
- Operationalise categories and use tallies/checklists
- Distinguish covert and overt observation and apply ethics
Observation records behaviour directly
An observation collects data by watching participants. In a structured observation, the researcher selects behaviours in advance and records fixed, operationalised categories on a tally chart or checklist. In an unstructured observation, the researcher records a broader range of behaviour without fixing all categories in advance.
Categories need observable boundaries
A category such as ‘cooperates’ is too open to interpretation. Define an action—for example, ‘hands a shared item to another participant’—so observers can agree when to record it. Clear rules can improve consistent observation.
Participants may or may not know they are observed
In an overt observation, participants know the observer’s role. In a covert observation, the role is hidden or disguised. Covert observation may reduce behaviour changes caused by being watched, but raises ethical questions about consent and privacy. This syllabus does not require participant/non-participant or controlled/naturalistic observation types.
Pause and explain
Which response best shows understanding of observations: recording behaviour consistently?
Worked example
A researcher records every time a student raises a hand during a 15-minute lesson. What makes this structured?
Show the worked solution
- The behaviour is selected in advance.
- A count can be recorded on a tally chart.
- The observation uses a fixed category.
Answer It is structured because the researcher records a pre-selected, countable behaviour using a fixed rule.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A study records a tally whenever a participant offers a seat to another person. Why is this category more useful than ‘is kind’?
Give me a hint
Compare a visible action with a value judgement.
Compare my reasoning
- Offering a seat can be directly observed.
- ‘Kind’ depends on interpretation.
- The specific action is easier to record consistently.
It defines a visible behaviour, improving consistency between observers.
Look for these in your work
- Identifies observable action
- Contrasts judgement
- Explains consistency
A participant sees an observer taking notes and knows the study role. Is this overt or covert?
Give me a hint
Does the participant know they are watched?
Compare my reasoning
- The observer’s role is visible.
- The participant knows observation is happening.
- This is overt observation.
Overt observation.
Look for these in your work
- Uses role visibility
- Uses participant awareness
- Names the type
Researchers consider hiding their role to watch students in a private setting. State one potential methodological reason and one ethical issue.
Give me a hint
Consider behaviour change and participant rights.
Compare my reasoning
- A hidden observer may reduce changes caused by awareness.
- The participants may not have given informed consent.
- Privacy and possible harm must be considered before the observation.
Covert observation may reduce reactivity, but consent and privacy concerns must be addressed.
Look for these in your work
- Gives a methodological reason
- Names consent/privacy
- Connects to ethical review
Common mistakes
- Using broad judgement words without observable definitions.
- Assuming covert research is automatically ethical.
- Teaching observation categories excluded by this syllabus.

Predefined operationalised behaviour categories
A fixed set of observable actions is chosen before data collection.

Make it stick
How do structure, operationalised categories and observer visibility change an observation study?
