How well we pay attention while learning is influenced not only by external distractions like background noise but also by internal factors such as how interesting we find the material, according to a study recently published by researchers at Bar-Ilan University. The research recorded brain activity (EEG) and physiological arousal (skin conductance) from 32 participants as they watched a 35-minute educational video lecture. Segments were presented either in quiet or with background construction sounds, either continuous drilling or intermittent air-hammers. Participants repeatedly rated how interesting they found the content and answered comprehension questions to assess their understanding.
