How to tell if your child may be a psychopath: It’s all about laughter, study says

LONDON — Laughter may be contagious for most of us, but a new study finds that boys who don’t feel compelled to giggle when their peers do are more likely to later become psychopaths.

Researchers at University College London recruited 92 boys between ages 11 and 16 for a study on how social reactions as an adolescent could predict later behavior. About two-thirds of the participants had been diagnosed with disruptive behaviors or callous and unemotional (CU) traits.

It’s worth noting that CU traits and disruptive behavior have been previously linked to an increased risk of developing psychopathy.

For their experiment, the researchers used fMRI scans to measure the brain activity of participants as they listened to sounds of both fake and real laughter, occasionally interspersed with crying. While listening to these noises, participants were asked to rate on a seven-point scale the degree to which they believed the laughs they heard were genuine. They also noted the extent to which they were emotionally affected.

Adolescents who demonstrated both risk factors for psychopathy reported less of an urge to laugh in conjunction with others than those who were believed to have one or neither. This finding was supported by the results of the fMRI scans, which showed reduced brain activity in regions associated with emotional reasoning.

While “it is not appropriate to label children psychopaths,” as psychopathy is a personality disorder experienced by adults, the signs can be detected at an early age, according to senior author Essi Viding.

Future research can explore whether other friendly social cues, such as smiling, words of encouragement, and displays of love, also prompt a lackluster emotion response from those at risk for psychopathy. Ultimately, these at-risk adolescents may simply experience life differently than the rest of us, Viding suggests.

“Those social cues that automatically give us pleasure or alert us to someone’s distress do not register in the same way for these children,” she says in a statement. “That does not mean that these children are destined to become antisocial or dangerous; rather, these findings shed new light on why they often make different choices from their peers.

“We are only now beginning to develop an understanding of how the processes underlying prosocial behavior might differ in these children,” she continues. “Such understanding is essential if we are to improve current approaches to treatment for affected children and their families who need our help and support.”

The study is published in the journal Current Biology.

  2. That’s silly. A psychopath simply waits to see if other people are laughing. Then he knows its time to laugh

  3. FU Paths are the evolutionary apex, you stupid emotional morons jerked around like women.

  4. Poor attribution here. We’re told the names of one author and the journal in which it appeared, but not identity as to what the formal background of the researchers were. On it’s face it looks like shabby research with over-reaching conclusions, and consequent questionable ethics regarding the labeling of subjects who would score one way or the other on such a test.

    1. It’s not new that most of these types of studies aren’t able to be replicated. Calling it junk science is an insult to junk science.

  5. Progressives’ idea of science. Urgh.

    I was taught when I was a kid that only fools laugh in public. Yeah, I know, different times, when people cared about decency.

    So apparently I’m a sycopath, unlike all the idiots on Fakebook/YouTube who broascast themselves laughing for no reason whatsoever, or worse yet, hurting/torturing other people.

  6. I laughed my a&shyss off when Trump won on Nov 8. I saw thousands of sycopaths crying like p&shyissies that night and ever since.

  7. so many people did not read the article or are too retarded to understand it.

    it is talking about CONTAGIOUS LAUGHTER If you do not know what that means, you may or may not be a psychopath, but you are a legit idiot.

  9. The government NEEDS to use this as a data point to place people on a watch list, no fly list, and firearms purchase ban.

  10. It’s important to tie alleged mental conditions to objective measures like brain waves and cerebral blood distribution because diagnoses have usually been subjective, made by people with social authority nobody dares challenge.
    Whenever a so-called mental problem comes to attention, lately autism for example, cases multiply much like witches during a medieval panic.
