Adam Gazzaley, “The Distracted Mind: Ancient Brains in a High-Tech World”
Show #153 | January 7, 2017 | We are obsessed with our devices. We pride ourselves on our ability to multitask — read work email, reply to a text, check Facebook, watch a video clip. Never mind the errors in the email, the near-miss on the road, and the unheard conversation at the table. In The Distracted Mind, Adam Gazzaley and Larry Rosen — a neuroscientist and a psychologist — explain why our brains aren’t built for multitasking, and suggest better ways to live in a high-tech world without giving up our modern technology.
The authors explain that our brains are limited in their ability to pay attention. We don’t really multitask but rather switch rapidly between tasks. Distractions and interruptions, often technology-related — referred to by the authors as “interference” — collide with our goal-setting abilities. We want to finish this paper/spreadsheet/sentence, but our phone signals an incoming message and we drop everything. Even without an alert, we decide that we “must” check in on social media immediately.
Gazzaley and Rosen offer practical strategies, backed by science, to fight distraction. We can change our brains with meditation, video games, and physical exercise; we can change our behavior by planning our accessibility and recognizing our anxiety about being out of touch even briefly. They don’t suggest that we give up our devices, but that we use them in a more balanced way.
Adam Gazzaley is founder and director of the Neuroscience Imaging Center at UCSF’s Memory and Aging Center. He is a professor in neurology, physiology and psychiatry at the UC San Francisco and director of the Gazzaley Lab, a cognitive neuroscience laboratory. His laboratory studies neural mechanisms of perception, attention and memory, with an emphasis on the impact of distraction and multitasking on these abilities. His unique research approach utilizes a powerful combination of human neurophysiological tools, including functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and transcranial magnetic and electrical stimulation (TMS & TES). A major accomplishment of his research has been to expand our understanding of alterations in the aging brain that lead to cognitive decline.
