If unable to brief before always try to debrief afterwards especially if deception was used and offer support if needed.
Fully informed consent is needed for a study. if this is not possible there are other forms of consent that could be used.
Parental consent: used for research involving children. Aim to get assent from the child as well.
Presumptive consent: from someone else with a similar background or someone who knows the participant.
Prior general consent: consent obtained before the study, without detailed knowledge of what will happen.
Retrospective consent: obtaining consent afterwards. (only if no alternative procedure available).Used with presumptive consent.
Without consent the participant may display demand characteristics.
Storing the data correctly so participants can not be identified. eg. use of code number instead of names. This includes storage of the data.
Making sure the participant is not harmed physically or psychologically during the study. If needed offer support in the debrief.
Allowing the participant to withdraw at any time during the experiment, even after the study has been conducted. The experimenter has the responsibility to stop collecting data if the participant shows signs of distress.
Should be avoided in all studies. This will help to avoid demand characteristics affecting the study.
They are easier to remember if you come up with an acronym for them.
