Correlating Psychopathy With Speech Patterns

florescent_beige writes "Researchers from Cornell and UBC report that analysis of speech patterns using Wmatrix, along with something called the Dictionary of Affect in Language (see a demo here), shows that psychopaths speak differently from other people, at least statistically (abstract). Although they say that these differences are 'presumably beyond conscious control,' the authors do not say if the method has any predictive use. Regardless, the popular press has already gone headline-nonlinear about it."

As the vote count was close, Gore could have given the exact argument to Bush. Of course such reversible arguments are non-arguments, and such a-holes like Bush use them because they can't hide their identity well enough. They have a set of ways of acting and reacting which fools some people, but not those who take note.

    For the budding psychopaths out there who want to "fit in" better with society, here's how to change your speech patterns.

    1) Join Toastmasters along with someone you see frequently (a significant other, close friend, or coworker).

    It's cheap, and they will teach you ways to improve your speech - how to recognize disfluencies, for instance.

    2) Play a game with your partner where every time they hear you make a mistake, they say "ding!". That's all - just "ding!" every time they hear a problem.

    (For what it's worth I've found that GF's are particularly good at noticing such flaws.)

    It takes a week or two, but the constant feedback will eventually sink in and you'll be able to hold long conversations without saying "ah", "um", "you know", and so on.

    3) Rhythm, meter, and pauses are more difficult. Find a newscaster whose vocal style you like and record one of their broadcasts.

    It doesn't matter whether you agree with their point of view, only that you like their vocal variety. (You could choose Rush Limbaugh, for instance.) I chose Morley Safer.

    Edit the broadcasts into individual sentences and rip these to a CD as individual tracks. While you are driving to work, play a sentence on infinite repeat. Recite the sentence along with the speaker over and over. Try to recite it exactly, mimicking the pauses and intonations.

    You'll spend a few iterations just remembering the words. Once you know the words, your ear will start to pick out subtle emphasis and pauses used by the speaker. You'll start to learn when to pause (after prepositions, for instance), where to put emphasis to make a point, and so on.

    When you get bored, switch to another sentence.

    Don't do the mimicry thing more than a couple of weeks or you'll end up sounding *exactly* like the broadcaster. Switch to another one, mix it up a little.

    As a side effect of all this, people will view your method of speech as more meaningful, you will be perceived as more reliable and confident, and people will give you greater respect.

    Funny, nothing you suggest here about the harms of homosexuality are psychological harms. You realize that the DSM is designed to classify people who are experiencing mental problems, right? So, "lack of procreativity" shouldn't be included, or else being post-vasectomy would be in the DSM. "Increased STD occurrence" shouldn't be included, or else refusing to wear a condom would be a cause for being in the DSM... as would being a teenager. Social effects and suicide rates? They examined those issues, it turns out that not all homosexuals experience social problems, nor do they all attempt suicide. In fact, some homosexuals seem to be quite well adjusted and capable of performing well in a professional career. The psychologists knew this, because they had well adjusted people working in their field.

    Leaving it out of the DSM is pure politics, not evidence-based medicine.

    It wasn't pure politics. There was a lot of politics, because the only reason why being homosexual was in the DSM was because people believed that you couldn't be homosexual without having mental, and/or social issues. As more and more psychologists came out as being homosexual, it forced the community to recognize that, hey, being homosexual did not automatically imply that the person required psychological intervention.

    Before these psychologists came out, the only homosexuals that the psychologists ever dealt with were ones who were already having "comorbid" psychological issues. So, it turns out that the psychologists thought that homosexuality automatically implied psychiatric distress was because the only people who admitted to being homosexual to them were people who were in psychiatric distress. There was a confirmation bias going on. Mentally healthy homosexuals didn't come out, and so they were hidden. And they were hidden for good reason: to avoid discrimination.

    As a total hyothetical, take for example the idea that the only time doctors ever saw an appendix was if it were inflamed and infected. They would naturally presume that the only state an appendix exists in is inflamed and infected. After all, they had never seen an uninfected appendix. Now, imagine that they finally do find someone who has died, and has an uninfected appendix. Clearly, it is now not the case that appendices are pathological. They're simply a variation of human anatomy.

    In the same way, psychologists were forced to recognize that homosexuality does not automatically present with mental health issues. Other ancillary conditions of homosexual body health are not sufficient to make homosexuality into a mental health disorder.

    As a final note: women are more susceptible to STDs, they have a higher incident of uterine, ovarian, and cervix cancer, and in fact, there are special parts of hospitals devoted solely to treating women. Does this mean being a woman should be declared a mental health disorder? No, clearly not. It's noted on their charts like being a smoker, as there are ancillary health issues that any doctor should be aware of, but "being a smoker" is not a health disorder, and neither is "being a woman". Just like "being homosexual" is not a health disorder.

    Psychopaths have trouble because they don't actually have any empathy. Psychopaths do not have to kill people, or anything like that. They simply are utterly uncaring about how other people feel in any respect. (And most of them are smart enough to fake otherwise.)

    Because they do not understand stuff that is obvious to everyone, they often end up explaining why they did something that was just obvious to everyone.

    And this isn't just bad things. Psychopaths often do good things because people are watching, and they know that society says that's what they're 'supposed' to do. But they don't actually think that.

    So when you ask them about why they held a door for an old person, their actual reason is 'Because I looked good doing that', but they obviously can't say that, so they'll come up with some sort of reason that doesn't make much sense.

    Whereas normal people say, "Uh, because she was having trouble with it, duh."

    Normal people automatically act towards each other in a certain way. Even criminals _feel_ that way, even if they ignore it. Psychopaths are doing mostly the same thing, but by rote. They learned the rules and follow them.

    For psychopaths, explaining behavior in moral terms is like someone with literally no sense of humor trying to explain jokes. You could study jokes, and why and how they're funny, and laugh at the right places and fool people, but, in the end, if asked to explain, your explanations of any specific joke are distinguishable from people with actual sense of humor, at least with enough analysis.
