Please take time to read the following information carefully.

What is the purpose of the study?

The purpose of the study is to investigate how an individual’s facial perception can be affected by obstructions on different parts of the face. The present study is also interested in investigating factors that can contribute to misperception such as when the observed face and the observer are of the same ethnicity

Why have I been invited to participate?

This study is on adults aged between 18 and 70. A total of 40 people (20 Caucasians and 20 Asians) who do not have prosopagnosia will be asked to participate. You have been invited to take part in this study due to being within the criteria of our target audience of adults.

Do I have to take part?

No. It is up to you to decide whether or not to take part. If you do decide to take part you are still free to withdraw unprocessed data at any time after reaching the end of the survey by clicking the 'withdraw consent' button

What will happen to me if I take part?

If you choose to take part in the study, you will be presented with an online questionnaire in which you will be asked to make aesthetic judgements of pictures of faces. This experiment should take no longer than 20 minutes to complete.

What are the possible benefits or disadvantages of taking part?

There are no direct benefits of taking part in this study. However, outcomes of this study will help to further develop research on the effect of face occlusions on perception and we also hope that you will find the experience interesting. Furthermore, all data collected from this study will be used to help with the researcher’s third year dissertation project. Other than the time you spend answering the questionnaire, there are no risks or disadvantages of taking part in this study.

Will what I say in this study be kept confidential?

Yes. You will not be asked to give any information that could be used to identify you personally (e.g., your name, date of birth, IP address). Confidentiality, privacy and anonymity will be ensured in the collection, storage and publication of research material (subject to legal limitations). Research data will be stored in Qualtrics and Google Drive, for which the University has security agreements, or Pavlovia (for which the privacy policies can be found here: https://pavlovia.org/docs/home/ethics), or uploaded to a repository so that it can be shared for teaching and research purposes.
