Overheard phone conversations: super irritating, but actually not that distracting

Why is it so annoying to hear a person chatting away in public on their mobile phone? One possibility examined in a new study is that the sound is particularly distracting, more so than a nearby conversation between two people who are both physically present.

Veronica Galván and her colleagues had 164 undergrads take part in what they thought was an investigation into the links between anagram solving performance and reading comprehension. While the students attempted to solve 15 easy and 15 tricky anagrams, they were subjected to the surprise sound of a nearby student chatting away on their mobile phone, or to the sound of two students chatting to each other.

Afterwards the participants rated the overheard phone call as more noticeable and irritating, and yet they performed just as well on the anagram task, solving as many easy and difficult puzzles as those participants who were exposed to a conversation between two nearby students. This represents a failure to replicate the main result in a 2010 study, in which one half of a conversation was found to be more disruptive to performance than a two-sided conversation.

Galván's team also tested the participants' memory for the words uttered in the overheard conversations, and the participants who overheard the mobile phone call did better. The researchers said this suggests there's something particularly "attention grabbing" about an overheard phone call. However, this isn't necessarily the case - the participants who overheard the two-sided conversation between two students were exposed to far more words. "It's possible that participants who overheard the one-sided conversation performed better on the recognition task because of experimental confounds," the researchers admitted.

The results confirm prior surveys suggesting that overheard mobile phone calls are perceived to be unusually annoying, but they don't support the idea that this is because they're super distracting. "We did expect to see a difference in anagram performance between conditions and did not," the researchers said.

It's a useful piece of realistic research that suggests we should look elsewhere for why overheard phone calls are judged so negatively. Perhaps many of us endorse an implicit rule that says it's rude to talk on your phone in public, and that's why we find it so irritating.

Although the main result was that an overheard mobile phone call harmed anagram performance no more than an overheard two-way conversation, you wouldn't know it from much of the media coverage this paper has attracted. "Hold the line: Overheard phone calls more distracting than room full of people chatting," was the Independent's take. "It's Harder to Tune Out Cell Phone Talkers Than Regular Human Conversations," said The Atlantic. Whether it's Facebook turning us into friendless hermits or TV turning our eyes square, it seems the mainstream media can't resist another chance to indulge their technophobia, even when the study doesn't quite hit the mark.

    Rudeness may be part of it, but it is not the only reason. In the 2010 study that you mention, Emberson and colleagues examined performance during exposure to one-sided and two-sided conversations. Participants performed worse during the one-sided conversation even though they knew it was part of the study (rudeness was not a factor), heard the one-sided conversation twenty-four times, and were presumably not surprised by it. Participants did worse on both tasks even though they were exposed to a one-sided conversation contained less words/ noise.

    There are many reasons as to why overheard cell phone conversations are annoying yet interesting at the same time. the idea that the person listening to the conversation can imagine the conversation based upon what the person they can see looks and sounds like. they then can create the person on the other line how they portray them to be. they picture them and the conversation on how they think it is based on their opinions about the person speaking. Social psychologists use the term explicit cognition to refer to these deliberate, conscious mental process involved in percepts, judgment's, decisions, and reasoning's. people can make decisions based on how the person talking sounds like, looks like, and even by the way stand. so therefore we could create a whole new story about what the actual phone caller is talking about. that is referred to as social influence. social influence focuses on how your behavior is affected by other people and behaviors.
