Q

What are ethical issues?

A

When there is conflict in between the rights of the participants and the goals of conducting an experiment to produce authentic and valid results

36
Q

What is the BPS code of ethics?

A

A document made by the British Psychological Society (BPS) that instructs psychologists what behaviour is and isn’t acceptable when dealing with human participants

37
Q

What is informed consent?

A

This includes making the participant aware of the aims of the experiment, the procedures and their rights

38
Q

What does the acronym PC DRIP stand for?

A

P - Privacy
C - Confidentiality
D - Deception
R - Right to withdraw
I - Informed consent
P - Protection from harm

39
Q

What is privacy?

A

A person’s right to be free from public attention in personal spaces

40
Q

What does deception mean?

A

Deception means misleading or withholding information from the participant at any point within the experiment

41
Q

What is protection from harm?

A

This means that participants should not be placed in any more danger than they would be in during their normal life

42
Q

What is the “right to withdraw”?

A

This means that participants can withdraw themselves or their data from the experiment at any point during or after the experiment

43
Q

What does confidentiality mean?

A

Refers to our right to have our data remain disclosed unless it has been agreed to be shared in advance

44
Q

What should a consent form contain?

A

Some or all of the conditions to gain informed consent, reassure confidentiality will be kept, give the right to withdraw, leave a place to sign

45
Q

What are standardised instructions?

A

What the participant will be expected to do, must include all essential points and address all ethical issues

46
Q

How do you write a debrief?

A
  1. Include the full aim of the study and remind the p which condition they took part in
  2. They should be reassured their behaviour is typical or normal
  3. They should have the right to withdraw their results
  4. In extreme cases where they may have suffered stress, ask them if they may require counselling (protection from harm)
  5. Thank them for taking part
  6. Ask them if they have any questions

A

A mathematical technique used to investigate association between two variables

Q

What is positive correlation?

A

As one variable increases, so does the other

70
Q

What is negative correlation?

A

When one variable increases, the other decreases

71
Q

What is zero correlation?

A

When there is no relationship between the co-variables

72
Q

What is the correlation coefficient?

A

The number which tells us how closely the variables are related (between 0-1)

73
Q

What is qualitative data?

A

Data which is expressed in word and not numerical (may be converted to numbers)

74
Q

What is quantitive data?

A

Data which can be counted, usually given as numbers

75
