An institutional review board (IRB) is a committee that reviews, approves, and monitors biomedical and behavioral research conducted on humans. Its purpose is to assure that participants' rights are protected during the course of research. 

Deception may be necessary to study subjects' true behavior, as people may behave differently if they know they are under observation or know the exact purpose of the study being performed. However, deceiving subjects simply because they might be upset if they knew the truth is not a valid ethical reason to do so.

Informed consent in psychological research means the subject is given enough information on the study to make an informed decision on his/her participation. This includes informing the subject that s/he can withdraw consent and leave the study at anytime.

The American Psychological Association (APA) has certain ethical guidelines when it comes to using animals for research. Experiments must be designed for the most minimal amount of suffering possible and the animals must be treated in a humane way. They have to have been acquired from a legal source, and it must be made clear why it is that animals must be used for this particular scientific end.

A requirement by the American Psychological Association (APA) is that the participant in a human study must give informed consent. That is, they must know they are involved in a study and give written consent. There can't be any extreme deception about the study; the participant must have an understanding of the expectations and premise of the study.

Once the research is completed, the identity of the people involved in the study, under absolutely no condition, may be revealed. The identity of the participant will never be made an integral part of the study, and there are no forms that allow for this.

According to American Psychological Association (APA) guidelines, a participant in a study cannot be placed under significant mental or physical risk. There are no forms that the participant can sign that would allow for these conditions in a study.

The debriefing procedures according to American Psychological Association (APA) guidelines are such that after the experiment, participants are told the end goal of the study and ways to attain the results. Doing so before the experiment could affect the results in an undesirable way, and so this information is provided to the participant after the experiment is completed.

The American Psychological Association (APA) guidelines for participation in a psychological study are such that there may be no involuntary partcipants or coercion involved in the study. The participants must provide clear and written informed consent before participating in the study.

Informed consent, confidentiality, anonymity, and debriefing are all aspects of an ethical study. Informed consent means that all subjects were given the necessary information for them to decide whether they wanted to participate in the study, or not. Confidentiality means that the experimenters will not release any information about subjects without their consent. Anonymity means that the experimenter does not know the identity of the subjects. Debriefing is when an experimenter tells the subject more information about the study's purpose and procedures after the study is completed.

Coercion means persuasion via threat or force, so coercion is NOT a feature of an ethical study.
