Electric “thinking cap” controls learning speed

From Vanderbilt University Research News. This article got a lot of traction this week. I would be very curious to see the results of the same study with tDCS applied at the time the tests were being given (rather than before). I’ve heard this described as ‘online’ testing.
Interesting to see Mind Alive’s Oasis Pro device being used clinically.

Reinhart and Woodman set out to test several hypotheses: One, they wanted to establish that it is possible to control the brain’s electrophysiological response to mistakes, and two, that its effect could be intentionally regulated up or down depending on the direction of an electrical current applied to it. This bi-directionality had been observed before in animal studies, but not in humans. Additionally, the researchers set out to see how long the effect lasted and whether the results could be generalized to other tasks.
