01 Nov Using Neurotechnology to Improve Language Learning
We are examining how different neurotechnologies can be used to enhance language learning. Currently, we are conducting a 5-session study (each session approximately 1.5-2.5 hours long, for total time commitment of ~8-10 hours) to evaluate the effectiveness of transcranial direct current stimulation (tDCS). tDCS is a non-invasive method in which we send low levels of electric current through different areas of the brain. Past research has shown not only that the levels of current used in tDCS are completely safe, but actually induce plasticity in the targeted brain regions, making it faster and easier to learn new things. We hope to apply this technology to learning a more complex skill like language.
In the study, you would be asked to fill out several questionnaires on the computer that collect demographic and language background information, as well as verify the safety of using the tDCS for you. You would then be asked to complete several computerized tasks that measure memory and language learning ability while the tDCS is on.
This study pays $15/hour, rounded to the nearest 20-minute interval (e.g., 1 hour and 10 minutes = $20). The study will take place in the first floor of Gutherie Hall at the University of Washington. Successful completion of all 5 sessions will include a $20 incentive bonus. In total, those who complete all 5 sessions should receive ~$140-170.
To be part of this study, you must be:
Monolingual in English (“functionally monolingual”)
Between the ages of 18-35
You CANNOT be in this study if you:
Have knowledge of any language other than English, especially any basic knowledge or previous exposure to French
Were exposed to other languages before the age of 7 that you are no longer, or never became, fluent in
Have had a major head surgery, seizure, stroke, or orbital fraction surgery
Have known neurological disorders, frequent or severe headaches, or family history of epilepsy
Have a current diagnosis of, or are taking medication for, a psychiatric disorder
Have non-removable metal in your body such as a cardiac pacemaker, aneurysm clip, cochlear implant, shrapnel, metal fragments in your eye(s), or neurostimulators
Are withdrawing from alcohol or drug addiction
Are pregnant or think you could be pregnant
Many of these criteria are set for your own safety. If you have any questions about the eligibility criteria, please don’t hesitate to ask.
