tendency to describe behaviour as better than average
36
RESEARCH ETHICS what are research ethics
standards of behaviour for psychologists doing research
37
RESEARCH ETHICS what are 5 general ethical principles of psychologists
1 beneficence + non maleficence 2. fidelity + responsibility 3. integrity 4. justice 5. respect for people's rights and dignity
38
RESEARCH ETHICS what does beneficence and non maleficence involve
1. cost benefit ratio | 2. protection
39
RESEARCH ETHICS what does fidelity and responsibility involve (2)
1. participants trusting experimenters | 2. participants trusting that they will hear about risks
40
RESEARCH ETHICS what does integrity involve
researchers reporting data honestly
41
RESEARCH ETHICS what does justice involve (2)
(1) researcher must not deny person of benefits of participating in study (2) researchers must not limit participation for reasons unrelated to study
42
RESEARCH ETHICS what type of individuals should be chosen to be participants in research
participants that will benefit from outcomes of research
43
RESEARCH ETHICS what is eligibility criteria
attributes of participants that will allow them to contribute to research question meaningfully
44
RESEARCH ETHICS what does respect for people's rights and dignity involve
(1) researchers keeping data confidential | (2) researchers making it clear participants can drop whenever
45
what is Institutional Review Board (IRB)
committee that assesses whether research will be carried out in way that is consistent with ethical principles
46
what is informed consent
participants agree to participate after all details are given
47
what ethical principle is related to informed consent
respect for people's right's and dignity
48
what is vulnerable pop
unable to provide informed consent
49
what criteria makes person vulnerable (2)
1. decisional impairment or | 2. situaltional vulnerability
50
what is decisional impairment
participants have reduced ability to provide informed consent
51
what is situational vulnerability
participants freedom of choice compromised by external source
52
how should researchers deal with participants with decisional impairment
1. obtain informed consent from guardian (guardian "ok") | 2. obtain assent from vulnerable participant
53
how should researcher deal with situational vulnerability
protect from exploitation
54
what is deception
holding back information about purpose and procedures during informed consent process
55
what criteria is required for deception to be approved (3)
1. researchers should not cause emotional or physical discomfort to participants 2. researches should prove deception is only way to conduct study 3. deception should not affect well being of participants throughout study 4. deception should not affect rights of participants throughout study
56
when is correlation used
when descriptive methods used
57
what is correlation
measure that captures direction + strength of relationship between 2 variables

1. variable that is not focus of study | 2. variable that can influence study if not controlled
76
what are 2 aims of sample selection
1. ensure groups are fair | 2. ensure groups representative of population

78
what is stratified random sample
1. divide pop into subgroups | 2. SRS within each subgroup according to proportion of pop they make up
79
what is experimental group
group that receives treatment of interest
80
what is control group
group that does not receive treatment of interest
81
what does placebo group control for
