Types of Observational Methods
Choosing where and how to observe makes a massive difference to your results. Naturalistic observations happen in real-world settings where behaviour normally occurs, giving you high ecological validity because people act authentically. The downside? You can't control variables, making it harder to replicate your study.
Controlled observations move the action to an artificial setting where researchers can manage variables better. This boosts reliability since conditions stay consistent, but people might behave unnaturally in these staged environments.
The researcher's role matters too. Participant observers join the group they're studying, gaining incredible insights into what it really feels like to be part of that situation. However, they risk losing objectivity by getting too emotionally involved. Non-participant observers stay on the outside, maintaining better objectivity but potentially missing the deeper understanding that comes from direct experience.
Covert observations (secret watching) capture completely natural behaviour since people don't know they're being studied. This raises serious ethical concerns about consent and withdrawal rights. Overt observations solve ethical issues by getting proper consent, but participants might change their behaviour when they know they're being watched.
Remember: Each observation type involves trade-offs between getting natural behaviour, maintaining ethical standards, and ensuring reliable results.
