Introduktion
One ethical consideration in the biological approach is informed consent. Informed consent means that before participants agree to participate in a study, the researcher must explain the purpose of the study which means the aim.

They have to explain the procedure of the study which means the steps the participants will be exposed to. In addition, the researcher must explain the person’s rights – including the right to withdraw and that all data will be kept anonymous.

Also, researchers are generally not allowed to lie to participants, but deception is often used. Informed consent means that the participants were not deceived before they agreed to participate.

Any potential negative effects of participation must also be explained. The p.s must sign an informed consent before taking a part in study.

Utdrag
The biological approach has some special problems with regard to informed consent. First, the biological approach uses animals which cannot actually give consent. In addition, biological researchers often do studies on people who have mental illness or brain damage.
