What is a consent form used for in usability testing?

A consent form in usability testing serves a crucial purpose by establishing clear agreements between the participant and the researchers regarding the study's parameters. It is primarily used to inform participants about their rights, the nature of the study, any risks involved, and the intended use of the data being collected. By signing the consent form, participants are agreeing to partake in the usability test and allowing their interactions to be recorded.

This is essential for ethical research practices, as it ensures that participants are aware of what they are consenting to, which promotes transparency and respect for individual autonomy. This form of documentation also protects the researchers legally and supports the integrity of the research process.

The other options do not accurately describe the primary function of a consent form in the context of usability testing. For instance, while documenting participant feedback is vital, it is typically done after the consent has been obtained. Agreeing on payment terms and defining project timelines are also important aspects of project management but are not functions of a consent form in usability testing.
