UCL Deafness Cognition and Language Research Centre


Research Participation

DCAL is always keen for people to volunteer to take part in our research. Most of our projects will require participants who are Deaf and who use British Sign Language (BSL). All information about consent, data protection, privacy information and questions will be provided in English and in BSL. If you have further questions please email us at dcal@ucl.ac.uk.

Why do we have a participant database? 

In the past, different DCAL researchers contacted the same people inviting them to be involved in their projects.  Information wasn't shared. This means that sometimes the same tests and questions were given to the same people and this was time consuming for everyone. 

So, now we are asking people to join the DCAL database which holds limited information about individuals. All information is confidential. This makes is easier for DCAL researchers to contact people who are suitable for their studies. It also means that you only have to answer questions about yourself once, and not every time you are involved in a DCAL project. 

We can contact you and tell you about a study.  If you are interested you can agree to take part, if not you can say 'no' or 'not at the moment'. This stops you being contacted too many times. We can also use the database to feedback results to people who are involved in our research more efficiently.

This database is only accessed by researchers at DCAL and all information is kept confidential.   

Our research would not be possible without your participation, so thank you for your time.

It only takes 5 minutes to join and all the information is provided in BSL.

Projects currently recruiting

BSL Sentence Task

We are currently looking for deaf people who are interested in how BSL works. Are you deaf, 18 years or older, born in the UK, and using BSL as your main language? We invite you to participate in an online sentence task. 
This involves watching videos of BSL sentences. We ask you to tell us how typical you think they are of everyday BSL. We will pay you £15 for your time. The only things you need are an internet connection and a computer or a tablet with a web browser.
If you are interested, please get in touch via dcal.researchadmin@ucl.ac.uk Or click here for more information in BSL or English: https://bslcorpusproject.org/projects/bsl-syntax-project/bsl-sentence-task/

Lateralisation of language processing in deaf people 

Hearing people who are right handed use the left side of their brain to carry out the majority of their language processing. We are examining whether the same is true of people who are deaf using functional Transcranial Doppler Sonography  (fTCD), a reliable non-invasive measure of the speed of blood flow through the main arteries supplying the brain. This research will inform our understanding of how the brain processes language.

We are currently looking for deaf participants with a cochlear implant(s) who received their implant before they 9 years old. Participants should also be right handed,  profoundly deaf before three years old and aged 18-50 years old.
