Asked to “study something important,” students stayed on task for two minutes before they “began responding to arriving texts or checking their Facebook feed,” reports a study, published in the May issue of Computers in Human Behavior, by Larry Rosen, a psychology professor at California State University-Dominguez Hills. The middle, high school and college students spent only 65 percent of the 15-minute observation period doing their schoolwork.
“We were amazed at how frequently they multitasked, even though they knew someone was watching,” Rosen says. “It really seems that they could not go for 15 minutes without engaging their devices,” adding, “It was kind of scary, actually.”
Media multitasking while learning means less learning, writes Annie Murphy Paul on the Hechinger Report.
. . . evidence from psychology, cognitive science, and neuroscience suggests that when students multitask while doing schoolwork, their learning is far spottier and shallower than if the work had their full attention. They understand and remember less, and they have greater difficulty transferring their learning to new contexts. So detrimental is this practice that some researchers are proposing that a new prerequisite for academic and even professional success—the new marshmallow test of self-discipline—is the ability to resist a blinking inbox or a buzzing phone.
In “Generation M2: Media in the Lives of 8- to 18-Year-Olds,” a 2010 survey, almost a third of those surveyed said that when they were doing homework, “most of the time” they were also watching TV, texting, listening to music, or using some other medium.
College students are used to texting, emailing and surfing the web in class. Eighty percent of college students admit to texting in class.
Young people think they can do two challenging tasks at once, but they’re “deluded,” says David Meyer, a University of Michigan psychology professor. “Listening to a lecture while texting, or doing homework and being on Facebook—each of these tasks is very demanding, and each of them uses the same area of the brain, the prefrontal cortex.”
He adds,“There’s nothing magical about the brains of so-called ‘digital natives’ that keeps them from suffering the inefficiencies of multitasking. They may like to do it, they may even be addicted to it, but there’s no getting around the fact that it’s far better to focus on one task from start to finish.”
