Teng Lab Experiment Participation

The Cognition, Action, and Neural Dynamics Lab seeks participants for a neuroscientific study on braille reading. While you read a series of braille texts, we will track your fingers and brain activity using EEG, a common, non-invasive, and completely safe technology. Our goal is to learn more about how the hands and brain work together to read and understand tactile writing. We are looking for participants meeting the following general criteria:

• Age 16 and up
• Blind from an early age with no history of visual print reading
• Proficient in Grade 2 contracted braille reading
• Comfortable sitting still for up to 3 hours (with breaks) and reading different braille texts

What to expect if you participate:

You will visit our lab facility at a mutually agreed time. While seated in a comfortable chair, you will wear a snugly fitting fabric cap fitted with the EEG electrodes. We will apply a safe, nontoxic conductive gel to each electrode that can be washed out afterward, either at the lab or at home. We will tape a small sensor to your braille reading fingertip(s). In this way we will measure your finger and brain while you read a series of texts printed on sheets of braille paper. In some cases you may be asked to read part or all of the text aloud. The entire experiment, including preparation, may take up to 3 hours, divided into separate sessions if necessary. Participants will be compensated $30/hour during the experiment, plus reasonable transportation expenses to get to and from the lab.

What kinds of studies do we do? The details depend on each individual experiment, which we will describe to interested participants during recruitment. Generally our experimental sessions are between 20 minutes and 2 hours long (depending on the study) and involve some combination of the following methods:

• Lab computer-based experiments. Make judgments about sounds or images presented via VR, computer monitor, and/or headphones in our testing booths.
• Physical experiments. Use sound, vision or touch to make judgments about physical objects or environments.
• Mobility and locomotion. Move about a space in or near our institute, or move your head/body while stationary, to capture naturalistic ways of interacting with your real or virtual environment.
• Finger position tracking. Move your hands over or near objects, for example reading a braille text, while we measure the positions and motion of your fingers.
• Electroencephalography (EEG). Wear a cap fitted with electrodes and a conductive gel while we record electrical signals from your scalp in our lab.
• Magnetoencephalography (MEG). Some studies will be performed at the Biomagnetic Imaging Laboratory at UCSF's Parnassus campus. Similarly to EEG, your brain activity will be recorded by a suite of sensors around your head, but they will be magnetometers in a solid housing rather than electrodes in a cap.
• Magnetic resonance imaging (MRI). For some studies we may collect an MRI scan to image the precise shape of your brain, also at UCSF's imaging facilities.
• Virtual/remote data collection. Some perception experiments can be conducted online via web browser, and some virtual studies may involve simple survey data collection via web or phone. We may contact individual participants via the form linked above, or recruit using our platform on Prolific.com.
