Q

covert observation

A
  • the psychologist goes undercover and does not reveal their true identity
  • may even give themselves a new identity
  • the group does not know they are being observed

Q

naturalistic observation

A

a researcher observes participants in their environment and there is no deliberate manipulation of the independent variable (IV)

Q

naturalistic observation advantages

A
  • participants are usually unaware that they are being observed (covert observation) so there is reduced chance of observer effects which occur when pps change their behaviour because they know they are being observed, invalidating the results
  • high mundane realism and ecological validity
  • useful when the deliberate manipulation of variables would be impractical or unethical

Q

naturalistic observations disadvantages

A
  • impossible to have any control over extraneous variables
  • problematic to try to determine cause and effect
  • risk of observer bias which occurs when observers know the aims of the study, or they hypotheses, and this knowledge usually influences their observations

Q

controlled observation

A

researcher observes participants in a controlled environment and this allows for manipulation of the independent variable

Q

controlled observation disadvantages

A
  • lower mundane realism and ecological validity
  • observer effects could occur as pps usually know they are being observed (overt observation)
  • risk of observer bias

Q

operationalised behavioural categories

A
  • specific and observable behaviours to be recorded during an observation
  • represent the more general construct under the investigation

Q

what do behavioural categories do

A
  • allow observers to tally observations into pre-arranged groups
  • provide a clear focus for the researcher
  • enable the proposal of a testable hypothesis
  • allow for a more objective /scientific data recording
  • provide data that is easier to quantify/analyse
  • should result in greater reliability

Q

observer bias

A

when the observer knows the aims of the study, or hypotheses, and this knowledge influences their observations

Q

how to avoid observer bias

A

inter observer reliability
- using two observers who agree beforehand on their interpretation of the behavioural categories
- each observer than observes pps at the same time, but records observations independently
- recordings will be correlated using an appropriate statistical test to ascertain their level of agreement
- if observers agree, the study has inter-observer reliability

intra-observer reliability
- when an observation is video recorded so that is can be watched several times

Q

time sampling

A

recording all behaviours within a given time frame e.g. noting what a student is doing in a lesson every 30 seconds

17
Q

event sampling

A

recording every time a certain behaviour (or event) occurs in a target individual or individuals e.g. counting how many times a person smiles
