research methods 1 - the observation method Flashcards
pages 46-55
4 features of an observation
- systematic measurement of spontaneously occurring behaviour
- can be conducted in a controlled or naturalistic environment
- can be structured or unstructured
- researcher decides which behaviours they’ll record beforehand to reduce observer bias
what are the types of observation
- naturalistic and controlled
- structured and unstructured
- participant and non participant
- covert and overt
evaluate naturalistic observations
strengths:
- high levels of ecological validity (natural environment)
- minimised demand characteristics (pts unaware of observation)
weaknesses:
- no control over extraneous variables
- if pts are unaware it raises ethical issues
evaluate controlled observations - 2 each
strengths:
- researchers have high control over situation to reduce extraneous variables
- high level of reliability (easy to replicate)
weaknesses:
- possible demand characteristics (pts know of the observation)
- low ecological validity (artificial environment)
evaluate structured observations - 2 each
strengths:
- high levels of reliability
- easy and quick to analyse the quantitative data produced
weaknesses:
- pts may be affected by the fact they know their behaviour is being recorded
- low ecological validity
evaluate unstructured observations - 2 each
strengths:
- high levels of ecological validity
- all behaviours can be captured
weaknesses:
- low level of reliability
- if pts are unaware of observation it raises ethical issues
evaluate non participant observations - 3 each
strengths:
- researcher can obtain more in depth data as they are in close proximity
- limits observer bias; due to the fact the researcher isn’t involved in behaviour it is less likely to affect the participants behaviour
- observation readings more accurate as they are recorded in real time
weaknesses:
- researchers presence may influence participants behaviour
- hard to observe all participants behaviours equally
- limits the behaviours that can be studied
evaluate participant observations - 3 each
strengths:
- investigator effects are less likely as researcher isn’t visible
- allows researchers to observe behaviour that may otherwise be out of their reach
- less chance of demand characteristics
weaknesses:
- loses objectivity, more subjectivity (we will see what we “expect/want” to see
- cannot record behaviour as it occurs so it is more inaccurate
- less proximity means that the researcher may miss behaviours
evaluate overt observations
strengths:
- limits ethical issues (informed consent)
weaknesses:
- investigator effects may reduce validity
evaluate covert observations
strengths:
- high ecological validity (unlikely investigator effects)
weaknesses:
- ethical issues (no informed consent)
what is a naturalistic observation
takes place in the participants natural environment
what is a controlled observation
takes place in some form of controlled environment
what is a structured observation
- data would be gathered using a pre written collection grid or coding sheet to record frequency
- produces quantitative data
- standardised
what is an unstructured observation
- researcher uses direct observation to record behaviours as they occur
- no predetermined plan
- transcript
what is a non participant observation
psychologist doesn’t participate in the group and simply observes
what is a participant observation
when psychologist feels the need to join in the behaviour of the group
what is a covert observation
when the researcher doesn’t tell the group they are being studied
what is an overt observation
when the researcher does tell the group they’re being studied
what is time sampling
when observer records behaviour at regular time intervals
( record behaviour every 30 seconds for 2 minutes )
evaluate time sampling ( 2 each )
strengths:
- less tiring for observer as they get rest periods
- reduces time needed to spend observing, may increase accuracy
weaknesses:
- observer may miss behaviours during non observation time
- monitoring the time intervals may be inaccurate or difficult
what is event sampling
when an observer decides in advance which behaviours they will observe and records every time the event occurs
evaluate event sampling
strengths:
- easier to conduct than time sampling
- less likely to miss behaviours
- useful when the behaviour that the researcher is interested in doesn’t happen very often
weaknesses:
- can be long for the observer because
