6. Ask the ppts to discuss their experiences of the experiment.

Question 4

How to deal with ethical issue of informed consent

Answer 4

1. Presumptive Consent: gaining consent from a similar set of students who won’t be doing the study
2. Prior Informed Consent: getting consent from ppts of things that ‘could’ happen
3. Parental Consent: when ppts are too young to give consent, this is gained from parents
   Retrospective consent = ppts give/don’t give consent during debrief
