Do we trust people who speak with an accent?

A recently published study shows that unless they speak in a confident tone of voice, you're less likely to believe someone who speaks with an accent. And, interestingly, as you make this decision different parts of your brain are activated, depending on whether you perceive the speaker to be from your own 'in-group' or from some type of 'out-group' (e.g., someone with a different linguistic or cultural background).
