In a study of different types of distraction involving more than 1,000 participants, researchers statistically derived a novel measure—dubbed the "d factor"—that could represent a person's general tendency towards distraction and may be linked with attention-deficit/hyperactivity disorder (ADHD). Han Zhang of the University of Michigan, Ann Arbor, and colleagues presented these findings in the open-access journal PLOS ONE on October 25, 2023.
