23
Social Desirability Bias
Answering questions in a self report to look better/exaggerate your abilities in a non-truthful way
24
Filler Question
Disguising what you're actually testing for so participants cannot prepare for the test, to get the most accurate results
25
Interview
A verbal question-and-answer discussion/conversation
26
Structured interview
A question-and-answer conversation that has a set format to follow
27
Semi-structured interview
A question-and-answer conversation that is slightly formatted, but also can be random
28
Unstructured interview
A question-and-answer conversation that is not formatted whatsoever and is random
29
Subjectivity
A statement that is up for interpretation (opinion that cannot be backed up by fact)
30
Objectivity
A statement that can be proven
31
Naturalistic observation
Observing/watching an individual/group of people in their natural environment
32
Controlled observation
A study conducted by watching the participants' behavior in a situation in which the social or physical environment has been manipulated by the researchers
33
Unstructured observation
Watching everything play out naturally in an experiment
34
Structured observation
Structuring/planning things to happen to observe within an experiment
35
Behavioral categories
Categories of behavior an experimenter will observe
36
Participant observer
An observer who secretly plays a part in an experiment without the other participants knowing (acts as a participant but isn't)
37
Non-participant observer
An observer who doesn't play a part in the experiment (could be either a covert or overt)
38
Overt observer
Being visible to the group you're observing
39
Covert observer
Being hidden from the group you are observing
40
Hypothesis
A testable statement based on the aims of an experiment
41
Alternative hypothesis
Predicting the direction of change (same as directional hypothesis)
42
Non-directional (two-tailed) hypothesis
Predicting the occurrence of change, but not which direction it will go in
43
Directional (one-tailed) hypothesis
Predicting the direction of change (same as an alternative hypothesis)
44
Null hypothesis
A testable statement saying that any difference or correlation in the results is due to chance
45
Informed consent
The participant knowing enough about the study to decide whether or not they will agree to participate
46
Privacy
Participants' EMOTIONS and PHYSICAL SPACE should not be invaded (e.g. They should not be observed in situations or places where they would not expect to be seen)
46
Right to withdraw
Participants should know that they can remove themselves, and their data, at any time (before, during, or after the experiment)
47
Confidentiality
Participants' results and personal information should be kept safely and not released to anyone outside of the study
48
Debriefing
-Giving participants a full explanation of the aims and potential consequences of the study at the end of a study is vital -so that they leave in AT LEAST as positive a condition as they arrived
49
Deception (3 points)
-Participants should not be deliberately misinformed (lied to) about the aim or procedure of the study -If this is unavoidable, the study should be planned to minimize the distress risk, and participants should be thoroughly debriefed. -It may be done to reduce the effects of demand characteristics but should be avoided.
50
Replacement
Researchers should consider replacing animals with alternatives like videos from previous studies or computer simulations
51
Species and Strain & What are 3 key things you should CONSIDER
The chosen species and strain should be the least likely to suffer pain or distress CONSIDER: -Were they bred in captivity? -Have they been in previous experiments? -What is their ability to think and feel?
52
Number of animals (what is vital for this?)
Only the minimum number of animals should be needed to get reliable and valid results (good experimental design is vital for this)
53
Procedures: Pain and Distress
Research causing death, disease, injury, physical or psychological distress/discomfort should be avoided where possible
54
Reward, Deprivation, and Averse Stimuli
-Using deprivation of the normal feeding/drinking patterns should be considered so that their needs can be satisfied -The use of rewards should be considered rather than the use of punishments to control behavior
55
Housing
Isolation and crowding can cause distress, so cage conditions should depend on the social behavior of the creature
56
Anaesthesia, Analgesia, and Euthanasia
Animals should be protected from pain using appropriate anaesthesia and analgesia for surgeries, and euthanised if suffering lasting pain
57
What are order effects?
Differences in the participants' responses that result from the order in which experimental materials are presented to them
58
Counterbalancing is used to overcome ____ in a _________ design experiment
Counterbalancing is used to overcome order effects in a repeated measures design experiment. (ABBA, BAAB)
