At the department of maxillofacial surgery in the UZ Brussel, we are studying the fakeness of the lips. We have selected pictures of lips of random people and we have made 4 surveys: one in English, one in Dutch, one in French and one in Spanish. We are asking you to evaluate the fakeness of the shown lips. It takes 8 minutes to complete the survey.
Please click on one of the following links to participate in our survey. You can also complete multiple surveys because they contain other pictures.
English survey: Lip fakeness survey
Dutch survey: Fakeness van de lippen
French survey: Étude lèvres
Spanish survey: Encuesta sobre falsedad labial
Thank you for your participation,
