Synaesthesia survey at
Birkbeck, University of London

Welcome, and thank you for your interest in our synaesthesia research! This short questionnaire is designed to learn more about how people experience sensory connections, such as seeing colours when reading letters or hearing sounds. Your participation will help us understand the fascinating diversity of synaesthesia. We may get in touch with you in the future if there's a research opportunity.

To answer this question, please read the consent form below first, and in the end, confirm that you've read it.

Introduction
Synaesthesia is sometimes described as a “joining of the senses” in which stimuli in one sensory modality can trigger automatic experiences in another modality; e.g., perceiving colours or shapes when listening to music, or perceiving colours when thinking about a particular day of the week (e.g., Tuesday induces yellow, Wednesday induces green). Many other sensory combinations are possible (e.g., taste, smell, touch, emotions).

Questionnaire
This questionnaire is administered by the Synaesthesia Research Team at the School of Psychological Sciences, Birkbeck, University of London, led by Dr Rocco Chiou. Its aim is to understand a little bit about you and the types of synaesthesia that you might have. The information you provide is valuable in helping us understand more about synaesthesia. Your participation is entirely voluntary, you are not under any obligtion to take part in any subsequent resarch, and you are free to discontinue the questionnaire at any time.

Registration for Future Research
If you do complete the questionnaire, your details will be added to a register of potential participants who may be invited in the future to take part in studies conducted by the Synaesthesia Research Team. Please note that you are not obliged to participate in any future research projects and you may contact us at any time to remove your name from the registry. For each particular study that we invite you to take part in, you will be given detailed information on what the study involves, either by email, phone, or text message, so that you can decide whether or not you are interested in participating. You always have the right to remove yourself from research at anytime without having to give reason and without consequences. A summary of research results can be made available to you upon request.

Confidentiality
Access to your personal information is strictly limited. Any information, personal details (name, address, etc.) gathered in the questionnaire or subsequent research are confidential (except as required by law) and will not be passed on to anybody outside of our research group. In the event that you participate in future research, you will not be identifiable in any publications or presentations based on the results. Identifying details will not be released without your explicit consent.
