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
