Q

why is privacy and confidentiality unethical if broken?

A

-a researcher may obtain more
information from a participant than they
wish to give which could be an invasion of privacy, the participant may later
feel ashamed or embarrassed

Q

what is protection from harm ?

A

-psychologists have the responsibility to
protect their participants from harm,
including stress
-the risk of harm must be no greater than that which they are exposed to in
everyday life

Q

why is protection from harm unethical if broken?

A

-participants should leave the research in the same state as they entered it
-if they are harmed, they may suffer from long‐term effects

24
Q

how to deal with protection from harm?

A

-the researcher should remind participants of their right to withdraw throughout and after the research
-the researcher should terminate the
experiment if the level of psychological or physical harm is higher than expected
-participants should be debriefed at the end of the experiment & they may be referred to counselling

25
Q

what is a cost benefit analysis?

A

an ethics committee would weigh up the costs of the research compared to the benefits that the research would bring

26
Q

are reliability and validity the same?

A

no

27
Q

what is internal validity?

A

whether the results of a study were solely affected by changes in the independent variable

28
Q

what is external validity?

A

whether the findings can be generalised beyond the context of the research situation

29
Q

which factors could affect
the internal validity of a study?

A

-demand characteristics
-investigator effects
-extraneous variables
-order effects

30
Q

how to improve internal validity

A

control of variables through:
-standardisation
-random allocation in independent groups designs
-counterbalancing in repeated measures designs

31
Q

what three types can external validity be broken into?

A

-ecological validity
- temporal validity
-population validity

32
Q

what is ecological validity?

A

refers to the extent to which the research findings can be applied to other settings – predominantly to everyday life

33
Q

what is a weakness of lab based studies?

A

a lack of ecological validity
↳ due to the artificial setting of laboratory, it is difficult to generalise the findings to a more natural situation since behaviour may be very different

34
Q

how is ecological validity heightened?

A

both the setting in which the experiment or study takes place, and the tasks
involved must have mundane realism (be similar to everyday life)

35
Q

what is temporal validity?

A

refers to the extent to which research findings can be applied across time

36
Q

what is population validity?

A

the extent to which research can be applied to other groups of people

37
Q

which two ways do you assess validity?

A

face validity
concurrent validity

38
Q

what is face validity?

A

whether a test appears to measure what it’s supposed to measure

39
Q

who conducts a test of face validity?

A

a specialist in the given area

40
Q

what is concurrent validity?

A

where the performance of the test in question is compared to a test that is already recognised and trusted within the same field

41
Q

what is a laboratory experiment?

A

-the researcher manipulates the independent variable to measure the effect on the dependent variable
-conditions are heavily controlled to minimise the effect of any extraneous variables
(artificial setting)

42
Q

strengths of lab experiments

A

-high degree of control over extraneous variables → prevent confounding variables which negatively affect the DV
-high internal validity → cause and effect can be determined

43
Q

weaknesses of lab experiments

A

-lack external validity/ecological validity
↳ findings of the study cannot always be generalised to settings beyond the laboratory due to a lack of mundane realism

44
Q

what are field experiments?

A

-experiments that are carried out in natural conditions
-field’ is any location which is not a laboratory
-participants typically do not know that they are in an investigation = natural behaviour

45
Q

strengths of field experiments

A

-natural settings = higher level of ecological validity, in comparison to laboratory studies
↳ more likely to be representative of behaviour witnessed in everyday life

46
Q

weaknesses of field experiments

A

1) more natural setting = less control over extraneous variables
↳ these can become confounding variables & distort the findings meaning a firm cause and effect relationship cannot be drawn

2) there are ethical issues associated with field experiments, participants are often unaware that they are participants in a psychological investigation, they cannot give informed consent to take part → the research may involve a breach of their privacy rights

47
Q

what are natural experiments?

A

the experimenter cannot manipulate the IV, so the DV is simply measured and judged as the effect of an IV

48
Q

process of natural experiment + examples

A

-the behaviour of people affected by the naturally occurring IV (eg: flood) is either compared to their own behaviour beforehand, or with a control group who have not encountered the IV

49
Q

where can a natural experiment take place?

A

field OR lab:
it’s the IV which is natural in this type of experiment, not necessarily the context in which the investigation is taking place, participants could be tested in a laboratory

50
Q

strengths of a natural experiment

A

1) naturally occurring IV = higher external validity than lab and field experiments / real-life issues that are being studied rather than manipulated artificially

2) unique insights are gained into real-life situations, research can be conducted into areas of psychology that could not be generated for ethical reasons or because of logistical and practical constraints

51
Q

weaknesses of a natural experiment

A

1) no control over the environment & extraneous variables = difficult for the research to accurately assess the effects of the IV on the DV / confounding variable may have affected the results so a cause and effect relationship must be drawn with extreme caution, if at all

2) a naturally occurring event that interests researchers may only occur very rarely = limits the opportunity to generalise the results to other similar events or circumstances

52
Q

what is a quasi experiment?
(& examples)

A

-contain a naturally occurring independent variable (IV), but one which already exists → the IV is a difference between people such as gender, age or a personality
-the researcher examines the effect of this IV on the dependent variable

53
Q

where do quasi experiments happen?

A

field OR lab;
quasi experiments do not have to be conducted in a natural setting, they may also be conducted in a laboratory setting, under controlled conditions

54
Q

strengths of quasi experiments

A

allow researchers to compare different types of people easily & see differences between these groups which could not be ethically generated otherwise

55
Q

weaknesses of quasi experiments

A

1) participants cannot be randomly allocated to research conditions to remove bias, since the IV is a naturally occurring difference between the participants, the IV to which they belong is pre-decided → the psychologist will be less certain that the IV alone will have caused the effect

2) methodological issues associated with conducting quasi experiments, when quasi experiments take place under natural conditions, there is no control over the environment and extraneous variables, making it difficult to be sure that factors such as age, gender or ethnicity have affected the DV

3) when quasi experiments take place under lab conditions the high level of control means that the research often lacks ecological validity, and the findings cannot always be generalised to a real-life setting since behaviour may not translate outside of the research environment
