Which detail provides valid reasoning to support the author's idea that the glasses have an everyday application? (11) Another bonus is that the glasses let the user apply the system to real life. "We're integrating this into immersive activity where the user gets to choose the activity," Greco said. "And because they're choosing, theyre more engaged and naving a more successful outcome." (12) For example, he said, students can use the glasses while studying or doing schoolwork, helping them stay focused on the task and training them to control their attention (13) The first prototypes went out to clinics in 2014, and iterations of the glasses have been in testing ever since. The Harbin Clinic in Rome, Georgia, reported that clinicians were seeing results from the Narbis prototype in about half the time it normally took with other clinical neurofeedback, Greco said. In all, he said, four out of five patients who have trained with the glasses reported significant improvement in five or fewer 30-minute trainings, and people who take medication for attention difficulties are coming off those drugs after about 20 sessions, as opposed to the 30 sessions it usually takes with other neurofeedback techniques
