Q

what are the advantages of an observation?

A

what people say they do then what they actually do is often different so observations give us a different take on behaviour than other methods

Q

what are the disadvantages of observations?

A

observers may ‘see’ what they expect to see (researcher bias)
observations cant provide information about what people think or feel

Q

what is behavioural categories?

A

it separates a continuous stream of action into components the categories are arranged in a list with a code called a coding frame

Q

what are the advantages of behavioural categories?

A

it helps enable systematic observations to be made so information isn’t over looked

Q

what are the disadvantages of behavioural categories?

A

they may not cover all possibilities so some may not be recorded which will lower validity
poorly designed coding will also reduce reliability

Q

what is event sampling?

A

this is whemmn you draw up a list of behavioural categories then they count how many times they are ibserved over a specicif time period

Q

what is time sampling?

A

this is where you record behaviour at specific intervals like 5 seconds or 5 minutes or you can take a sample at diffrent times of they day or months

Q

what are the advantages of time and event sampling?

A

both methods help make the task more manageable because it avoids them having to record everything
time allowed to track time related changes in behaviour

Q

what is a controlled observation?

A

it is structured and certain things in the environment are controlled meaning some variables are manipulated by the researcher

Q

what are the advantages of a naturalistic observation?

A

its a realistic environment with spontaneous behaviour which mean it will have a high ecological validity

Q

what are the advantages of an unstructured observation?

A

it is useful when the behaviour which is being studied is largely unpredictable
used in initial investigation’s (pilot study )

21
Q

what are the disadvantages of an unstructured observation?

A

behaviours recorded are often the most eye catching but may not be the most important or relevant

22
Q

what are non participant observations?

A

the observer is not a participant in behaviour being observed

23
Q

what are the advantages of non participant observations?

A

increased objectivity because of psychology and also physical distance

24
Q

what are the disadvantages of non participant variables?

A

the observer may misinterpret the communications within the group because they are an outsider this can reduces the validity

25
Q

what is participant observations?

A

observer is participant in the behaviour being observed

26
Q

what is an advantage of participant observations?

A

likely to provide special insights into inside behaviour
able to monitor and record behaviour in close detail

27
Q

what are the disadvantages of participant observation?

A

objectivity reduced - observer bias
more difficult to record an monitor behaviour

28
Q

what is covert observations?

A

observations made without participants knowledge

29
Q

what are the advantages of covert observations?

A

participants behave more naturally because there not aware there being observed

30
Q

what are the disadvantages of covert observations?

A

raises ethical issues about observation because of deception and invasion of privacy

31
Q

what are overt observations?

A

participants are aware there being observed

32
Q

what are the advantages of overt observations?

A

avoids lack of informed consent because participants decide whether they want to do it or not

33
Q

what are the disadvantages of overt observations?

A

if participants know they’re being observed there likely to alter there behaviour - observer effect

34
Q

what is an experiment?

A

a research method which demonstrates casual relationship
they all have an iv and dv

35
Q

what is an independent variables?

A

it is a factor directly manipulated by the experimenter in order to observe the effect of this variation on the dv
there at least 2 levels of IV

36
Q

what is operationalisation?

A

variables need to be operationalised in a way they can easily be tested

37
Q

what is a dependant variables?

A

is whats measured by the experimenter to assess the effects of the IV

38
Q

what is an alternative hypotheses?

A

it is a statement about the relationship between variable e.g IV and DV
it should include both levels of IV
it should be precise and testable

39
Q

whats a one tailed (directional) hypothesis?

A

it states the direction of the difference in the hypothesis

40
Q

what is a two tailed (non directional) hypothesis?

A

it just states that there is a diffrence

41
Q

what is a null hypothesis?

A

a statement of no difference

42
Q

what is a repeated measure design?

A

each participant takes part in every condition under test

43
Q

whats an independent measure design?

A

participants are only tested once in either condition

44
Q

what is an advantage of repeated measures design?

A

there will be a good control of participant variables
fewer participants needed because they do all conditions

45
Q

what are the disadvantages of repeated measure design?

A

you will risk order effects because participant’s will be re tested and may become bored -you can stop this by counter balancing
condition a might be easier than condition b

46
Q

what are the advantages of independent measures?

A

avoids order effects because participants are only tested once
it avoids participants guessing the aim of the study

47
Q

what are the disadvantages of independent measures design?

A

theres no control of participant variables-can be dealt with random allocation
you will need more participants

48
Q

what is a matched pair design?

A

participants with key similar variables are paired - one is in group a the other is in group b

49
Q

what are the advantages of a matched pair design?

A

acts as a control for participant variables because of matching
avoids order effects

50
Q

what are the disadvantages of a matched pair design?

A

its time consuming to match participants on key variables
may nit control all variables because you can only match on known variables but there could be others that are important

51
Q

what are demand characteristics?

A

where participants change there behaviour because they have worked out what the experiment is about and want to give experimenters the results they want
