Why the Brain Doubts a Foreign Accent

What happens in the brain when you hear an accent--and why you are less likely to trust the speaker














Share on Tumblr

In a second experiment, participants were explicitly told that the goal of the research was to study how the difficulty of understanding people’s speech might affect the perceived credibility of their statements. Statements were still judged as less truthful when spoken in heavy than native accents, although participants were able to correct their judgments for mild accents. 

These findings have important implications for how people perceive non-native speakers of a language, particularly as mobility increases in the modern world, leading millions of people to be non-native speakers of the language they use daily. Instead of perceiving their speech as harder to understand, natives are prone to perceive their statements as less truthful. Consequently accent might reduce the credibility of non-native job seekers, court eyewitnesses, or college instructors for reasons that have nothing to do with xenophobia per se. 

But the ramifications of cognitive fluency are not all bleak for the intrepid immigrant and international visitor. Several recent studies suggest that modest disruptions of cognitive fluency – cases of cognitive “disfluency,” if you will – prompt people to think critically. For example, University of Michigan psychologists Norbert Schwarz and Hyunjin Song found that formatting a test in a difficult-to-read font dramatically decreased the number of people tripped up by trick questions like “How many animals of each kind did Moses take on the Ark?” [Answer: None – Moses wasn’t on the Ark, Noah was].   In effect, making people work harder to process the test questions made them less likely to make careless mistakes. College students, take heed: practice parsing your non-native teaching assistant’s accented speech might well augment your analytical skills.

    It's "hue and cry", not "hew and cry".

    Not if you hew your thumb. But, quite right. Use a cliche but spell it properly

    To all of the previous commentators - what is your native language?

    These results would also infer, to a lessor extent, that similar effects would be produced by native English speakers with a locally 'foreign' accent, such as Londoners in New York, New Yorkers in Texas, Texans in New Hampshire, Australians anywhere, etc.

    Test without quotes.

    When asked 'Are any of your relatives terrorists?', reply 'Only my mother-in-law'.

    Yeah, but hopefully they'll fix the double quote problem soon: it makes quotations difficult...

    Well, yesterday I couldn't comment at all. Even though I was duly logged in, when I tried to post a comment the system told me I couldn't post until my account had been checked, or something to that effect.
    Teething problems, probably.

    One of the cognitive side effects of my MS is an decreasing ability to even understand a person with an accent. (I was pretty good at one time.) Now on the telephone I constantly ask them repeat over and over and even spell out the words they are trying to say to me.

    I'm just some old guy, but I think I should share something with you. For 10 years I had several illnesses, including congestive heart failure and other conditions that required that be on chemo (Interferon) for nearly a year, twice. The interferon produced anemia, reducing my circulatory system's ability to deliver oxygen & nutrients to cells, and to extract cellular waste products. I was extremely weak for extended periods.

    In may, 2008 my cardiologist happened to prescribe Lovaza (omega-3-acid ethyl esters) solely to reduce my very unhealthy triglyceride levels. Over the next 2 weeks I suddenly became very interested in astrophysics and other subjects, and began keeping a journal of my thoughts. My intellectual abilities had suddenly and dramatically returned to pre-illness levels. I had been unaware of a cause, but investigating a little I found that there have been claims of non-prescription omega-3 dietary supplements helping intellectual abilities. I think that I had suffered some physiological damage due to my health issues that benefited from the Lovaza treatment. You can find more information at:
    http://en.wikipedia.org/wiki/Omega-3_fatty_acid
    Under the heading 'Psychiatric disorders':
    [n−3 fatty acids are thought by some to have membrane-enhancing capabilities in brain cells. One medical explanation is that n−3 fatty acids play a role in the fortification of the myelin sheaths. Not coincidentally, n−3 fatty acids comprise approximately eight percent of the average human brain according to Dr. David Horrobin, a pioneer in fatty acid research. Ralph Holman of the University of Minnesota, another major researcher in studying essential fatty acids, who gave Omega-3 its name, surmised how n−3 components are analogous to the human brain by stating that ''DHA is structure, EPA is function.''

    A benefit of n−3 fatty acids is helping the brain to repair damage by promoting neuronal growth. In a six-month study involving people with schizophrenia and Huntington's disease who were treated with E-EPA or a placebo, the placebo group had clearly lost cerebral tissue, while the patients given the supplements had a significant increase of grey and white matter.]

    It occurs to me that prescription Lovaza (1-2 grams daily) might offer at least some temporary benefit to you. This is just a guess on my part, but I suggest you discuss it with your doctors. In the worst case I seriously doubt it could harm you, except financially: it can be rather expensive. I can not attest to any benefits from omega-3 food supplements.

    jtdwyer,
    The answer is yes, as I can attest from my own experience as a linguist, having taught many Australian students, who sometimes asked me how come I still had a German accent, after so many years of living in their country?
    When I told them that they, too, had a strong
    accent which I sometimes found hard to understand, they were really surprised! It clearly shows that we are at our most 'parochial' ,jingoistic self-centerdness when it comes to our bias for'familiar' sounding lingo;because:
    There's no more homely twang than your mother tongue!
    Even in multicultural Australia, where SBS Radio and television channels often use BBC or CNN news in their national news, they take the trouble of having the texts read anew by an Australian voice -over!
    Our new Prime Minister, Julia Gillard, is known for her very distinctive ,drawn-out Australian accent, despite the fact that she was not born in Australia, but came from Wales as a four-year old girl. I found that young migrant children, in their effort to get 'accepted' by their peer group, typically tend to adopt the broadest local accent possible. We are at core 'social animals', and nowhere more so than deep down in our own brains' language lab!

    Just a little Aussie jab, but I'm not that funny. You probably never heard Merle Haggard sing "I'm Proud To Be An Okie From Muskogee!", but I grew up in Muskogee, Oklahoma, USA & moved around a lot, even Augsberg, Bayern for a while. Anyway, I never learned to talk right, so I just had to fake it wherever I went. I think that gave me a head start on this one - Thanks!

    Do you remember that Halloween in arabic means "they are sweet." in a full sentence? it is pronounced the same. though cake, which means the same think in arabic and in English, is pronounce diffenrently, same assonances for an old cliche'so in spanish, pastel,(same as cake, before you eat it, obviously, otherwise it will be for France an excrement), so pastel, or pastiglia is a french hue and and italian pill. It evolved after the diaspora, from the aramaic land, and so many example are around, like for example tax, still means time, and we got it as me, is pronounce water in arabic, I in italian, and the same in English. same assonance, different pronounciation, same origin, different evolution of this rhetorical specie.

    Trusting and distrusting of someone with an accent, was always endorsed and encouraged in every nationality and society on this planet.
    I believe it all started many eons ago, when the Barbarians were invading other lands to robe and destroy small villages and Countries.
    This practices were inbreed over many generations, in all the species of humans being (and it appears to be genetically encoded)
    It was a bad omen, and it will hunt us all, and fare all of us badly in the future, this is not our faults individually. The faults rest with the warlords and leaders of nations of the past, and with the leaders of murderous Barbarians.

    In fact, we could have learnt better things, which would have helped us along the years, things that would benefit us all individually.
    a) Always, consider Names persons have, analyse the meaning, (make sure the name they have, is theirs)
    b) Consider likes and dislikes, (use in reverse)
    c) Remember how trustfully a liar speaks? (Reverse your thought)
    In addition, of course, there are millions of proverbs and old sentences, you could consider.

    Well, it seems only logical to dislike foreign accents, so probably we'll have to train ourselves to be more tolerant and open-minded, even if we are not biologically equipped to do so.

    I doubt there's any innate dislike or distrust of "foreign" accents. Many people are actually attracted to foreign sounding (and looking, for that matter) individuals. When I look and listen around myself, I see so many happy mixed couples - mixed in terms of accents, languages, skin color, and ethnicity.

    I have ofen wondered if it is the increase in processing difficulty with new accents combined with the processing difficulty of understanding the difficult material that TAs are presenting that causes the complaints from undergrads. The same undergrads don't seem to complain about accents when they are interacting socially with internationals, and things like the SPEAK Test do not require the raters to understand difficult material while evaluating the accent.
