Research Methods Flashcards
What are the 6 ethical issues
Deception Informed consent Protection of participants from physical and psychological harm The right to withdraw The right to withdraw data Confidentiality and Privacy
Give examples of studies involving deception
Asch
Milgram
Cruchfield
What estimate of studies use no deception and who found this?
Menges
3% use no deception at all
How could deception be seen as always negative, despite the benefits?
It prevents informed consent. Researchers have an obligation to protect their participants and psychologists should be seen as professional and therefore trustworthy.
What should a debrief do?
- Inform the participants of the purpose
- Ensure no negative consequences
- Give the participant the right to withdraw data
Why can’t informed consent be given when deception is required?
Because informed consent involves the participants giving their consent in full knowledge of the aims of the study and the expectations of them. Not possible if things need to be kept from them
What are the exceptions to giving consent?
- Children under 16
- People detained (prison/patients)
- Field experiments
What are the guidelines for physical harm as an ethical issue?
Not to expose participants to anymore risk of harm than they would in day to day life
What examples of psychological harm could result from experiments
Embarrassment
Loss of self esteem
Stress
Anxiety
How do psychologists protect their participants from psychological harm?
Using confidentiality
What are the guidelines for confidentiality?
Participants are not identified unless they give their permission and various methods may be used to disguise their identity. For example in case studies patients may be identified only by their initials such as KF or HM.
List 5 ways in which ethical issues can be dealt with
- seeking consent
- avoiding deception
- giving right to withdraw
- debriefs
- confidentiality
What are ways of obtaining consent indirectly and avoiding deception?
- Presumtive consent: asking people of their views on a situation and if accepted the procedure is used but NOT on those asked
- Prior general consent: a group of possible participants are asked about a procedure and those who consider it acceptable are selected for the study
What does an experiment allow for?
Allows us to establish a causal link between the IV and the DV. Following an experimental procedure we should be certain that the alteration we have made in the IV has caused the change in the DV.
What are common confounding variables?
Intelligence of participants Personality of participants Gender of participants Time of day Weather Noise levels Temperature
What are the advantages of laboratory experiments?
- Cause and effect (able to make a link if conditions are controlled)
- Repetition (others can repeat to see if they get the same results)
What are the disadvantages of laboratory experiments?
- Lack ecological validity (too artificial compared to reality)
- Demand characteristics (participants behaving differently based on the scenario)
What are the advantages of a field experiment?
- High ecological validity (natural settings generally mean natural behaviour, most like real life)
- Less risk of demand characteristics (participants may not be aware they are being tested)
What are the disadvantages of field experiments?
- Less control of variables (more variables may affect outcome, cannot determine cause and effect)
- Ethics (if participants are unaware they are being tested then how can they give consent/withdraw?)
- Replication (difficult to make exact replicates)
What are natural experiments?
Experiments that take advantage of naturally occurring variables in a naturally occurring event
What are the advantages of natural experiments?
- Less risk of demand characteristics
- Research opportunities (researchers able to observe situations that would otherwise be unethical to set up as an experiment)
What are the disadvantages of natural experiments?
- Lack of control over variables
- Replication (rarely able to replicate, therefore hard to establish validity)
What are the advantages of the Repeated Measures design?
The participants are the same each time (no confounding variables, everything is kept constant because they are the same people
What are the disadvantages of the Repeated Measures design?
- Order effects
- Boredom
- Extra materials (e.g having to use 2 lists of words for a memory test - are they the same difficulty?)
