What is an observation?
-Is a research method when psychologists watch and record behaviour in a systematic way, without manipulating variables.
Why are observations a great way to study behaviour?
-As it naturally occurs and is useful for when self-report methods may be unreliable.
What is a naturalistic observation?
-When conducting a naturalistic observation, the researcher watches and records behaviour in the setting within which it would normally occur, this means all aspects of the environment are free to vary.
What is a controlled observation?
-With a controlled observation the researcher watches and records behaviour within a structured environment.
Why is a controlled observation useful?
-It can be useful to control certain aspects of the research situation, so a controlled observation may be preferred as the researcher has control over extraneous variable that might otherwise interfere with the results.
What is a covert observation?
-The participants’ behaviour is watched and recorded without their knowledge or consent.
-Researchers will usually watch from somewhere else hidden like from across a room or from a balcony.
-However, the behaviour should be public and happening anyway if the observation is to be ethical.
What is an overt observation?
-Participants behaviours is watched and recorded without their knowledge their knowledge and consent.
-This is observed through a consent from prior to the observation beginning.
What is a participant observation?
-In a participant observation the researcher becomes a member of the group whose behaviour they are watching and recording.
-Sometimes it may be necessary for the observer to become part of the group they are studying, as is the case with participants observations.
What is Non-participant behaviour?
-Are when the researcher stays separate from the people they are studying and records their behaviour objectively.
-This is often necessary when joining the group isn’t possible, for example, a researcher observing interactions between patients in a hospital ward or prisoners in a correctional facility, would be unethical or unsafe to participate directly.
What is inter-observer reliability?
-A way of measuring whether an observation is reliable.
-An observation requires the observer to tally the behavioural categories which may be hard to do because the observer may miss something and/or be biased. To measure whether the observation is reliable, inter-observer reliability is used.
Steps of inter-observer reliability;
Step 1: Two or more observers agree on the behaviour categories and sampling method to be used.
Step 2: They observe the same situation and independently tally the behavioural categories.
Step 3: They compare their results using a Spearman’s Rho test. If their results correlate by about 0.8 or more, the observation is deemed reliable.
Strengths of Observational studies in general:
-Have high validity, record what people actually do rather than what they say they do.
-May capture spontaneous and unexpected behaviour.
-Often used as a way to measure the DV in an experiment and so are a fundamental way of gathering data.
Limitations of Observational studies in general:
-Serious issue of observer bias
-Only observable behaviour is recorded and not information about what people think or feel, date from observations nuts be interepted carefully.
Strengths of Covert Behaviour
-Behaviour is natural.
-Can see real reactions.
Weaknesses of Covert observation
-Unethical because no consent.
-Observer may act differently because they know they are being watched.
Strengths of Overt Observation
-Ethical, participants give consent.
-Easier for observer to record.
Weaknesses of Overt Observation
-Behaviour may change, less natural.
-Participants may act differently because they know they are being watched.
Strengths of Naturalistic Observation:
-Behaviour is realistic.
-High ecological validity.
Weaknesses of Naturalistic Observation:
-Hard to control outside factors.
-Observations may be affected by other events.
Strengths of Controlled Observation:
-Easier to control variables.
-Easier to record specific behaviours.
Weaknesses of Controlled Observation
-Behaviour may be artificial
-Low ecological validity
Strengths of Participant Observation :
-Can gain insider perspective.
-Can understand feelings and motivations
Weaknesses of Participant Observation:
-Observer may influence behaviour.
-Difficult to stay objective.
