This is Scientific American's 60-Second Science. I'm Karen Hopkin. This will just take a minute.

Oohp, I gotta go. Sorry. I know that was irritating. Because a recent study in the journal Psychological Science shows that overhearing only half of a cell phone conversation is much more distracting than listening to two people chat.

When we follow a full conversation, we tend to fill in the blanks…anticipating what each of the speakers might say. But when we’re limited to just one side of a dialogue—or “halfalogue”—our brains have to work harder to guess what’s coming next. That unpredictability grabs our attention, which makes these partial exchanges hard to tune1 out.

Psychologists had volunteers perform tasks that required concentration. And while the subjects worked, they were treated to either a dialogue or halfalogue the scientists had previously2 recorded. The results: hearing just the “tete” in a cell phone tete-a-tete leads to poor performance in other tasks.
