Q

Strength of covert observation

A

Investigator effects are less likely so less chance of demand characteristics so behaviour will seem more natural and representative

Consists of observing people without their knowledge e.g one way mirror

Strength of overt method

A

More ethical than covert, so representation of psychological research as ethical is protected

Q

Weakness of overt observations

A

Investigator effects so they change their behaviour through demand characteristics , not authentic natural behaviour being observed

Q

Investigator effect

A

bias occurs when the investigator influences the behaviour of the participants in a way that’s not intended e.g facial expressions

Q

Strength of participant observation

A

Researcher can obtain in depth data since they’re in close proximity
Unlikely to overlook behaviour so allows comprehensive understanding

Q

Strength of non participant observation

Q

Reliability

A

Consistency of results

19
Q

Validity

A

Accuracy of results

20
Q

Controlled observation

A

Conducted under strict conditions e.g in an observation room or lab where extraneous variables can be controlled e.g time, noise, temp

21
Q

Strength of controlled observation

A

Can be replicated to check reliability so standardised procedures can be repeated by diff researches

22
Q

Standardised procedures

A

Making a test uniform, setting it to specific standard in which everyone is treated exactly the same and have the same experience

23
Q

Weakness of controlled observation

A

Lower level of external validity, due to artificial environment
Observation feels unnatural so may alter participants response so no longer representative of real life

24
Q

External validity

A

Findings that can be generalised, they represent the outcomes that occur in a wider population than just the sample

25
Q

Structured observation

A

researcher uses coded schedules according to previously agreed formula and organise data into behavioural categories . Predetermined questions, tools, items

26
Q

Behavioural categories

A

Breaking down the target behaviour (aggression) into components that can be observed and measured (hitting or kicking)

27
Q

Strength of structured observation

A

Researcher can compare behaviour between participants across groups
Use of behaviour categories makes coding of data more systematic (according to a fixed plan)

28
Q

Weakness of structured observation

A

Not very high internal validity because researcher may miss some crucial behaviours
Findings may lack the finer details

29
Q

Unstructured observation

A

Involves every instance of the observed behaviour being recorded and described in as much detail as possible

30
Q

Strength of unstructured observation

A

Richness of data obtained
Researchers obtain comprehensive view of human behaviour
High internal validity

31
Q

Weakness of unstructured observation

A

Prone to observer bias due to lack of objective behaviour categories
Problem with inter observer reliability as lack of constancy in observations

32
Q

Inter- observer reliability

A

Degree of agreement between people observing the same thing

33
Q

What makes something an experiment

A

Manipulating the IV and look at effect on DV

34
Q

Demand characteristics

A

participants changing their behaviours or responses based on what they think the research is about

35
Q

Social desirability

A

to answer questions in a manner that will be viewed favourably by others

36
Q

Control

A

The extent to which the variable is held constant by the researcher

37
Q

Confounding variable

A

an unmeasured third variable that influences both the supposed cause and the supposed effect.

38
Q

Mundane realism

A

The extent to which a study mirrors real life

39
Q

time sampling

A

where an observer records behaviour at prescribed intervals

40
Q

strength of time sampling

A

allows for a better use of time since fewer observations are made

41
Q

limitation of time sampling

A

not every behaviour of relevance to the inestigation will be counted if it occurs inbetween allocated time frames

42
Q

event sampling

A

observer records the number of times the target behaviour occurs

43
Q

strength of event sampling

A

every behaviour of interest in theory will be counted from beginning through to end of observation

44
Q

limitation of event sampling

A

theres a possibility that some behaviours could be missed if there is too much happening at same time, some not coded
