Why that nearby cell phone conversation bothers you...

While I am reading my morning newspaper in a restaurant at breakfast, nothing ticks me off more than a nearby cell phone conversation, but I'm not bothered by two people chatting nearby. Observation of Emberson et al. suggest why this might be the case:
Why are people more irritated by nearby cell-phone conversations than by conversations between two people who are physically present? Overhearing someone on a cell phone means hearing only half of a conversation—a “halfalogue.” We show that merely overhearing a halfalogue results in decreased performance on cognitive tasks designed to reflect the attentional demands of daily activities. By contrast, overhearing both sides of a cell-phone conversation or a monologue does not result in decreased performance. This may be because the content of a halfalogue is less predictable than both sides of a conversation. In a second experiment, we controlled for differences in acoustic factors between these types of overheard speech, establishing that it is the unpredictable informational content of halfalogues that results in distraction. Thus, we provide a cognitive explanation for why overheard cell-phone conversations are especially irritating: Less-predictable speech results in more distraction for a listener engaged in other tasks.

    More importantly, it's not just limited to cell phones, but regular phones, and with so many people working in cubicles these days....
