A small study into electronic device usage during lectures found that there was minimal difference in scores between those who were distracted while listening to the lecture and those who weren't when there was a quiz afterwards.
Results. The sample was comprised of 26 students. Of these, 17 were distracted in some form (either checking email, sending email, checking Facebook, or sending texts). The overall mean score on the test was 9.85 (9.53 for distracted students and 10.44 for non-distracted students). There were no significant differences in test scores between distracted and non-distracted students (p = 0.652). Gender and types of distractions were not significantly associated with test scores (p > 0.05). All students believed that they understood all the important points from the lecture.
Conclusions. Every class member felt that they acquired the important learning points during the lecture. Those who were distracted by electronic devices during the lecture performed similarly to those who were not. However, results should be interpreted with caution as this study was a small quasi-experimental design and further research should examine the influence of different types of distraction on different types of learning.

have a close friend who always knits during lectures in order to be able to focus her mind on what is being said. Otherwise her mind waders to hopelessly distracting topics. Knitting apparently takes just enough of her excess mental capacity that it helps her focus. I suspect it is an anchor that grounds her attention deficit somewhat.
I notice the same effect when I'm doing nonogram puzzles (entirely visual reasoning) while watching (well, actually listening to) Jeopardy. Potential answers pop into my head, whereas otherwise I keep wondering what the clue is they are trying to answer.
