44
Q

define lab experiments

A

conducted under controlled conditions
researcher changes IV to see effect on DV

45
Q

define field experiments

A

carried out in a natural setting
researcher manipulates IV to see effect on DV

46
Q

define natural experiments

A

the change in IV would have happened if the researcher wasnt there eg: heart attack number after smoking ban

47
Q

define quasi experiments

A

IV simply exists

48
Q

2 strengths of lab experiments

A

high level of control, inc validity
easy to replicate and check results

49
Q

limitation of lab experiment

A

lacks ecological validity due to control of researcher, findings cant be generalised

50
Q

strength of field experiments

A

good internal and external validity

51
Q

limitation of field experiment

A

less control, therefore extraneous variables can affect data, lowering internal validity

52
Q

strength of natural experiments

A

provides opportunity to research things that may not be ethical if they hadn’t occurred naturally

53
Q

2 limitations of natural experiments

A

may happen rarely, reducing research opportunities
may not be able to randomly allocate pps to conditions

54
Q

strength of quasi

A

controlled conditions, high external validity

55
Q

weakness of quasi

A

cannot allocate to conditions, may be confounding variables

56
Q

define a population

A

a group of people who are the focus of the researchers interest, from which a smaller sample is drawn

57
Q

whats a sample

A

a sample is the people who take part in study. they’re drawn from target population and presumed to be representative of that population

58
Q

random sample

A

everyone has equal chance

59
Q

strength, 2 limitations of random sampling

A
  • potentially unbiased, validity
  • time consumimg
  • may be biased sample
60
Q

systematic sampling

A

using a system to select eg: every 4th

61
Q

one strength, 2 weakness of systematic sampling

A

objective, researcher little influence
- time consuming
- may end up biased eg: every 4th was male

62
Q

stratified sampling

A

sample reflects proportions of people in subgroups

63
Q

one strength, 2 weakness of stratified

A

representative sample
- time consuming
- subgroups cant reflect how all people are different, therefore complete representation isnt possible

64
Q

opportunity sample

A

uses pps who are willing and available

65
Q

1 strength , 1 weakness of stratified

A

easy and inexpensive
may be biased ( similarities of interest? )

66
Q

volunteer sample

A

pps who have volunteered to be in study

67
Q

strength and weakness of volunteer

A

large samples reached
similiar characteristics

68
Q

what are self report techniques

A

methods of gathering data where pps provide into about themselves without interference

69
Q

difference between qualitative and quantative data

A

qualitative is detailed and focusses on opinions
quantitative is usually numerical

70
Q

open and closed questions

A

open is usually detailed, closed focusses on one answer questions

71
Q

5 things to include in good questionnaire questions

A
  • filler questions
  • open and closed
  • no double negatives
  • no leading questions
  • easy to hard
72
Q

4 strengths of questionnaires

A
  • quick and cheap
  • comfortable to reveal info
  • reduces experimenter bias
  • no special training
73
Q

3 weakness of questionnaires

A
  • biased to those willing
  • timely
  • cant ask questions
74
Q

difference between structured and unstructured questions

A

structured has pre determined questions and cant deviate from script, unstructured have new questions and may be based on last answer

75
Q

2 strengths, 2 weakness of structured interviews

A

easily repeated
easy to analyse questions
- interviewer bias
- comparability difficult if interviewer behaves differently

76
Q

strength, 2 weakness of unstructured

A

more detail obtained
- interviewer with skill needed
- expensive

77
Q

why do psychologists observe

A
  • to study natural behaviour
  • to study behaviours that are unethical
78
Q

name the 3 types of observation

A

controlled v naturalistic
overt v covert
pps v non

79
Q

difference between overt and covert

A

covert is where pps dont know they are being observed
over is where the pps knows and have given consent

80
Q

difference between time sampling and event sampling

A

event sampling is where the number of times the behaviour is carried out is recorded
time sampling is a pre determined time frame

81
Q

whats a correlation

A

measures extent of which two variables are related

82
Q

difference between a positive and negative correlation

A

a positive is a relationship where both variables move in the same direction, a negative is where an increase in one is a decrease in the other

83
Q

2 strengths of correlations

A

determines if theres a relationship
may suggest ideas for future research if correlation is strong

84
Q

2 weakness’ of correlations

A

only tell us variables are related, not why
dont demonstrate cause and effect ( which variable causes other )

85
Q

3 differences between correlations and experiments

A

experiments..
- asses effect of IV on DV, correlations dont use seperate conditions
- experiments look for difference
- bar chart vs scatter graph

86
Q

whats a meta analysis

A

large scale review where a researcher takes the data from lots of individual studies and analyses to get an overall picture

87
Q

what are the measures of cendral tendancy

A

averages which give info on the most typical values eg: mean, mode, median

88
Q

when do we use the mean?

A

when there are all data values
we dont use them when theyre extreme values

89
Q

what are measures of dispersion

A

based on spread of the scores eg: range, standard deviation

90
Q

whats standard deviation

A

measure which shows to what extend the values deviate from the mean

91
Q

whats a pilot study

A

a small- scale version of an investigation which takes place before the real one

92
Q

3 aims of pilot studies

A

no biased results
properly operationalised
behaviour categories are being properly observed

93
Q

strength of pilot study

A

pilot studies can be used to identify misleading questions and reduce bias, therefore, the internal validity increases and the reliability

94
Q

weakness of pilot study

A

just because a pilot study is successful, doesnt guarantee the actual will be
therefore
we cant accept that the pilot study will be a 100% recreation

95
Q

whats a peer review

A

all aspects of investigation are checked by experts ‘peers’ in the field

96
Q

3 reasons to peer review

A

allocate funding
amend research
validate quality and relevance

97
Q

3 negatives if we didnt peer review

A
  • damage integrity of the field
  • lead to misinformation
  • poor quality may be disseminated
98
Q

what happened with the MMR vaccine study, relating to peer review

A
  • 1998 Andrew Wakefield led a study that suggested vaccine caused autism
  • this was published and parents didnt vaccinate their children, leading to death
  • a 2014 meta analysis confirmed it was lies
  • rumours still persist
99
Q

2 strengths of peer review

A

protects quality
preserves reputation

100
Q

2 weakness of peer review

A

publication bias
anonymity of review may be used to criticise rival researchers

101
Q

2 examples of implications of psychological research on economy

A
  • attachment research into role of fathers. modern parents may be better equipped to contribute effectively
  • mental disorders cause time off work and lead to a negative effect on the economy
102
Q

define reliability

A

how consistently a method measures something
- repeat and obtain
- linked to replication

103
Q

define internal reliability

A

within study consistency, how consistently different items with 1 test measure same concept

104
Q

external reliability

A

similiar results over time/ situations in different conditions

105
Q

inter reliability

A

reliability within the study, is the result consistent

106
Q

external reliability

A

focusses in if the result is still consistent over different time periods and situations

107
Q

split half

A

split test in half, not only in half but eg: systematic
give pps both half
0.8 to be accurate

108
Q

test retest

A

test is completed over 2 time periods
0.8

109
Q

inter rater test
