We all know that multitasking is baaaaad.<\/p>\n

In fact, we all know that multitasking doesn\u2019t happen. Instead, when we think we\u2019re multitasking, we\u2019re actually switching rapidly back and forth between two tasks. (Or, heaven help us, more than two tasks.)<\/p>\n

\"multitasking\"<\/a><\/p>\n

If either of those two tasks is cognitively complex, this rapid task switching imperils performance.<\/p>\n

So, to repeat: multitasking is baaaaad.<\/p>\n

Surprising New Research\u2026<\/h2>\n

But what if, under unusual circumstances, it were beneficial?<\/p>\n

More precisely, what if the perception that I\u2019m multitasking<\/a><\/em> improves my performance.<\/p>\n

Here\u2019s how you might test such a question (especially if your name were Shalena Srna):<\/p>\n

Ask two groups of students to transcribe a Shark Week video.<\/p>\n

Tell half of them that they\u2019re doing two things<\/strong>: learning by watching, and also transcribing.<\/p>\n

Tell the other half that they\u2019re doing one thing<\/strong>: learning by watching and transcribing.<\/p>\n

In other words, both groups of students do the same thing. But: one group thinks they\u2019re multitasking, and the other doesn\u2019t.<\/p>\n

Sure enough, in this study, students who thought they were multitasking did better. They wrote more words, and they remembered more of the video.<\/p>\n

Wow.<\/p>\n

Curiouser and Curiouser<\/h2>\n

Srna and company didn\u2019t stop there. They kept testing their hypothesis.<\/p>\n

In another study, they asked students take a virtual art-museum tour. They told half of them that this required distinct tasks (listening and looking); the other half didn\u2019t get that instruction.<\/p>\n

Same results.<\/p>\n

In another version, they had participants solve two kinds of puzzles simultaneously: word searches and anagrams. Rather than tell half that the puzzles required dual-tasking (or not), they asked participants what they thought.<\/p>\n

Here again, those who spontaneously thought they were multitasking did better on the puzzles than those who didn\u2019t \u2013 even though they were all doing the same task.<\/p>\n

In Search of an Explanation<\/h2>\n

This result, to put it mildly, seems bizarre. If multitasking makes me worse at something, why would believing that I\u2019m multitasking<\/em> make me better?<\/p>\n

Srna & Co. suggest one plausible explanation. If I think I\u2019m multitasking, then I might concentrate harder on the task.<\/p>\n

To test their hypothesis, they measured participants’ pupil dilation when they did (or didn\u2019t) think they were multitasking. (We\u2019ve got good research showing that people who are more engaged in material have greater dilation.)<\/p>\n

Sure enough, people who believed they were multitasking had bigger pupils than those who did not.<\/p>\n

In fact, they rated themselves as less bored by the work they were doing.<\/p>\n

Teaching Implications<\/h2>\n

This research strikes me as a) fascinating, b) thorough and thoughtful, and c) a smidge dangerous.<\/p>\n

Here\u2019s what I mean.<\/p>\n

Given these (highly persuasive) studies, we might be tempted to tell our students that they\u2019re multitasking when they\u2019re not \u2013 because their extra level of concentration will improve their learning.<\/p>\n

Alas, such a response would mistake research<\/em> benefits for school<\/em> benefits.<\/p>\n

In this case, if we tell our students that they\u2019re multitasking, good things might happen in the short term. However, in the long-term, they get the message that we think it’s okay.<\/p>\n

But, it isn\u2019t. Rapid task switching reduces learning. It really does<\/a>.<\/p>\n

In fact, students get counter-productive, pro-switching messages all the time. We need to work against this cultural programming.<\/p>\n

(One key strategy: they should see us conspicuously refusing to multitask. Hard-core monotasking adults are great role models.)<\/p>\n

Reality Check<\/h2>\n

Srna and Co. begin their article with some amazing statistics. According to their survey, 84% of people think they\u2019re better-than-average multitaskers. In fact, almost 50% say they\u2019re tops in the field.<\/p>\n

Rather than use students’ false beliefs to help them today, we should correct their beliefs to help them for a lifetime.<\/p>\n","protected":false},"excerpt":{"rendered":"
