25
Dependent variable (DV)
The thing that you measure
26
Control variable
The thing that you keep constant
27
Within-subject / repeated measures
All participants are exposed to all levels/conditions of the independent variable.
28
Between-subjects / independent design
Different participants are exposed to different levels/conditions of the independent variable
29
Counter-balancing
Technique used to deal with order effects when using a repeated measures design. Half of the sample complete the first condition first and the second condition afterwards and the other half of the sample, the second condition first and then the first condition.
30
Order effects
Participants responses to various conditions are affected by the order of the conditions to which they are exposed
31
Experimenter bias
The unintentional influence of the experimenter's expectations, beliefs or preconceived notions on the outcome of a study or research experiment.
32
Participant bias
The conscious or unconscious effort of the participant to appeal to the researcher in a study rather than responding naturally.
33
Hawthorne effect
The modification of behaviour by study participants in response to their knowledge that they are being observed or singled out for special treatment.
34
Placebo effect
A person's physical or mental heath improves after taking a placebo.
35
Single-blind
The Participant do not know in what group they are in, in an experiment
36
Double-blind
Neither the participant, nor the experimenter know the what group they are in.
37
Confounds/extraneous variables
Variables that influence/interfere with an accurate measurement between the independent and dependent variable
38
positive/negative correlation
positive correlation: one score increases, and so does the other negative correlation: one score decreases, and so does the other
39
sample
A subsection of a population
40
population
An entire group with specific characteristics
41
Reliability and Validity
Reliable: something produces the same results after repetition of test/experiment/analysis Valid: Accurate measurement You can have reliability without validity but you cannot have validity without reliability
42
Null hypothesis significance testing (NHST)
To check whether a statistical relationship in a sample reflects a real relationship in the population or is just due to chance
43
p-value
The probability of the observed data under the null hypothesis, so if the independent variable doesn't affect the dependent variable psychologists typically use 0.5, or 5% as the cut-off: p < 0.5 -> statistically significant (reject H0 in favour of H1) p > 0.5 -> non-significant (fail to reject H0)
44
Type 1 error/false positive
A rejected null hypothesis that is actually true
45
Type 2 error/false negative
Acceptance of null hypothesis that is actually false in the population
46
Familywise error
Probability of making more false positive results (type 1 error) the more tests you run simultaneously
47
p-hacking
manipulation of p-value through "rounding off" p-value, not reporting all dependent measures/ conditions, selective reporting (file drawer problem)
48
HARKing
Coming up with the hypothesis after the results - reporting unexpected findings as predicted
49
Sharp-shooter fallacy
cherry picking specific data points or patterns
50
File drawer problem
selectively reporting studies that "worked"
51
Publication bias
Studies submitted after the results have been analysed -> only showing "appealing", "newsworthy" studies
52
Pre-registration
Writing down what you plan to do and your predictions before the data collection commences
53
Plagiarism
To take credit for someone else's work or ideas, etc. without appropriate credit
54
Falsification
Manipulating and/or distorting existing data
55
Fabrication
Making up data that did not previously exist
56
Non-sequiturs
A logical fallacy in which the conclusion does not logically follow the premises of the argument
57
Secondary analysis
the analysis of an existing data set to answer a new research question
58
Cross-sectional Research
Studying groups at one time point
59
Longitudinal research
Studying the same group over time
60
Cohort
A sample which is large and intended to be representative
61
Cohort effects
differences between cohorts due to differences in experiences, not e.g. age
62
practice/test effects
improvement/change in result due to repetitions
63
cross generational problem
changes in cohort specific to the specific cohort and their experiences and not generalisable
64
selective survival
A process that results in individuals with certain characteristics disproportionately surviving to old age
65
attrition/selective drop out
loss of participants from sample overt time - who drops out? is there a pattern of people that drop out
66
accelerated longitudinal study
a more structured multiple cohort design that takes multiple single cohorts, each one starting at a different age and follows them for a shorter period of time than a traditional longitudinal study
67
cross-lagged panel correlation analysis
A technique used in longitudinal, nonexperimental designs to draw inferences about the direction of a relationship between two variables
68
Internal validity
the extent to which a study's findings unambiguously establish a cause-effect relationship between the independent and dependent variable (usually produced in labs)
69
External validity
the extent to which a study's findings generalise to other settings and samples
70
Ecological validity
validity of study's finding in different settings/locations
71
Respondent burden
The participants burden of having to participate in a study, e.g. high respondent burden through multiple questionnaires in a day
72
Experience sampling method
Collection of data about a sample of daily experiences throughout specific points in a day of the participant
73
Day reconstructive method
At the end of the day, participants recall their experiences
74
Ambulatory physiological monitoring
Monitoring of physiological responses in the body throughout a day (heart rate, blood pressure, sweat, body temperature)
75
Randomised controlled trial
RCTs are prospective studies that measure the effectiveness of a new intervention or treatment
76
Quasi-experimental study
Compare treatment and control but not through random allocation
77
Efficacy
can it work? assessed in controlled lab/clinic setting
78
Effectiveness
does it work in real life? in a realistic setting
79
Efficiency
evaluate the cost/benefit of an intervention study
80
Feasibility study
to assess a proposed intervention, small scale study
81
Adherence / compliance
If there is no difference between the treatment and control group is it because the intervention does not work or because it wasn't adhered to correctly?
82
Volunteer bias
Study participants are volunteers, therefore they may be more motivated and engaged in a study than the whole target population
