In an experimental session, informed consent takes place before the experimental procedure begins (option D).
An experimental session is a term that refers to a session in which it is experimented to check patterns of human behavior from one or more variables that function as stimuli.
Additionally, when a person is invited to participate in an experimental session, informed consent must be provided. In this document, the participant will leave a written record that he is aware of what is going to be done in the experiment and removes the responsibility of the researchers for possible damages or negative consequences that this may bring.
Therefore, the informed consent must go before performing any procedure and the participant must read it completely and sign, implying that he is aware of all the pertinent information related to the experiment.
