Of course the journal article isn't open access. But hey, Google. "To see whether the difficulty with “just thinking” is distinctive to college students, in study 9 we recruited community participants at a farmer’s market and a local church. The par- ticipants ranged in age from 18 to 77 (median age = 48.0 years). As in study 7, they completed the study online in their own homes, after receiving instructions to do so when they were alone and free of any external distractions. The results were similar to those found with college students. There was no evidence that enjoyment of the thinking period was related to participants’ age, education, income, or the frequency with which they used smart phones or social media (table S2)." So apparently it's not related to the prevalence of distracting technology - according to them. I would question the second (S8) 'at home' studies which only used 15 people per experiment. This was to test whether allowing participants to distract themselves had any effect. It's a very short paper, only a couple of pages, so I think needs a bit more digging to actually find out whether it's true or not. The whole thing seems very speculative.
