Dr. Cohen Kadosh's pioneering work on learning enhancement and brain stimulation is one example of the long journey faced by scientists studying brain-stimulation and cognitive-stimulation techniques. Like other researchers in the community, he has dealt with public concerns about safety and side effects, plus skepticism from other scientists about whether these findings would hold in the wider population.
科恩・卡多什博士在学习促进和大脑刺激方面所做的开创性工作,从一个侧面反映了研究大脑刺激和认知刺激技术的科学家面临的漫长征程。和圈内其他研究人员一样,他曾面临公众对于安全性和副作用的担忧,也曾面临其他科学家关于上述发现在更广泛人群中是否成立的疑虑。
There are also ethical questions about the technique. If it truly works to enhance cognitive performance, should it be accessible to anyone who can afford to buy the device -- which already is available for sale in the U.S.? Should parents be able to perform such stimulation on their kids without monitoring?
这项技术也存在伦理问题。如果它真的能够增强人的认知表现,是不是应该让任何买得起的人都可以买到那款在美国已经有售的设备?是否应该让父母可以在没有监控的情况下为他们的孩子实施这样的刺激?
'It's early days but that hasn't stopped some companies from selling the device and marketing it as a learning tool,' Dr. Cohen Kadosh says. 'Be very careful.'
