23
Q

Random sampling

A

Defined as one in which every member of the target population has an equal chance of being selected

24
Q

Sampling bias

A

An imbalance in a sample that has an under or over representation of gender, ethnicity, age so that it is not represented of the target population

25
Generalizability
The ability to assume that the behaviors observed in the random sample are representative of those in the larger population
26
Reliability
Results can be replicated
27
Inter-rater reliability
It assesses the external consistency of a test to ensure that people making subjective assessments are all in tune with one another. This refers to the degree to which different raters give consistent estimates of the same behavior.
28
Test-retest reliability
A measure of the consistency of a psychological test across time. It administers a test twice at two different points in time and assumes that there will be no change in the quality or construct being measured.
29
Internal validity
When the research actually measures what it intended to
30
Ecological validity
The study represents what happens in real life
31
Cross-cultural validity
Is the research relevant to other cultures
32
Confounding variables
Undesirable variables that influence the relationship between the independent and dependent variables
33
Demand characteristics
When participants act differently simply because they are being observed
34
Hawthorne effect
When participants act differently simply because they know they are in an experiment and they try to guess the ends of the study and act accordingly
35
Researcher bias
When the experimenter sees what he or she is looking for or the expectations of the researcher consciously or unconsciously affect the findings of the study
36
Participant variability
When characteristics of the sample affect the dependent variable
37
Artificiality
When the situation created is so unlikely to occur that one has to wonder if there is any validity in the findings
38
Social desirability effect
When most people want to present a positive picture of themselves so they may not always tell the truth when asked personal questions in an interview
39
Ethnocentrism
refers to a tendency to use your own culture as the standard by which to judge and evaluate other cultures
40
Order effect
When you use the same participants and they would learn what to remember in the first trial and this would affect the second trial
41
Contamination
the analysis and trial and error processes of allowing information, anticipations, or other elements concerning a variable under examination to impact the gathering and perception of information about such a variable
42
Placebo effect
phenomenon in which some people experience some type of benefit after the administration of a placebo (a substance with no known medical effects)
43
Single-blind control
When participants do not know what the study is about
44
Double-blind control
Not only do the participants not know whether they are in the treatment or control group but the person carrying out the experiment does not know the aim of this study nor whether each group is a treatment or control group
45
Reflexivity
When the researcher needs to reflect on his or her own background and beliefs and how these could play a role in the research process
46
Counterbalancing
To help avoid order effect you divide participants into 2 groups so group 1 goes a to b, then group 2 goes b to a
47
Informed consent
Participants must be informed about the nature of the study and agree to participate
48
Deception
When researcher do not want the participants to know the exact aim of the research b/c it can effect the results
49
Protection of participants
To make sure that no harm is done to participants and it is not permitted to humiliate a participant or force them to reveal private information
50
Debriefing
At the end of all studies the true aims and purpose of the research must be revealed to the participants
51
Right to withdraw
The participants have the right to leave the study at any time and that they can withdraw their data at the end of the study if they wish
52
Confidentiality
All the information that is obtained in a study must be confidential
53
Stress and pain
Researchers should take measures to minimize stress and pain
54
Consider alternative ways
Researchers should consider whether there are alternatives to animal research
55
Approval of research projects by ethical committee
Researchers must ask for permission to conduct research with animals the application must include details of the study including potential harm to animals and possible benefits of that research
56
Researcher competence
The researcher must have skills and experience in doing research with animals
57
Theory
An explanation for a psychological phenomenon- used to summarize, organize, and explain observations; used to make predictions about observed events
