NASA Brain Training Tech Makes Smart Glasses

(1) A new pair of smart glasses uses a technique invented at NASA to measure users' brainwaves and tell them how well they're paying attention. Others
have used the NASA formula to help people train themselves to focus, as has the company's founder, but Narbis' new smart glasses are getting much
quicker results.
(2) The technique is based on neurofeedback, detecting brainwaves and showing users a readout of their own brain activity. With practice, they can then
learn to control it.
(3) NASA didn't invent neurofeedback. But in the 1990s, a scientist working on pilot training at NASA's Langley Research Center in Hampton, Virginia, came
up with a way to translate brainwave output to characterize attention levels. More and more of a pilot's job was being done by automated programs, and
researchers were becoming concerned that pilots, being less engaged, would have trouble maintaining focus.
(4) To help pilots train their attention, Langley researcher Alan Pope invented what he called an engagement index. The strength of higher-frequency beta
waves that result from greater concentration is divided by the combined power of alpha and theta waves-lower-frequency outputs associated with
relaxation. Pope's system then spit out a number, one through six, to indicate the level of engagement.
(5) His team tested the technique and found that subjects who were shown their engagement level while performing a task were able to learn to control their
concentration and outperformed control groups while reporting a lower perceived workload.
Staying on Task
(6) Clinical psychologist Domenic Greco worked with blofeedback therapy- which can be based on anything from brainwaves to heart rate - since the early

Answer 1

The text primarily uses description to connect ideas, explaining the development of neurofeedback technology and its adaptation into smart glasses, while detailing NASA's initial use for pilot training. The correct answer is option B.

Step-by-step explanation:

The author connects ideas in the text mainly through description to elucidate how the neurofeedback technology was developed and its potential applications. This descriptive structure leads the reader to understand the historical development of the technology, its initial use by NASA for pilot training, and its eventual adaptation into smart glasses. It details the problem NASA faced with pilot engagement, the solution they developed, and the subsequent testing and application of the developed technology.
