    Default Genes predispose some people to focus on the negative


    (UBC News) A new study by a University of British Columbia researcher finds that some people are genetically predisposed to see the world darkly.

    The study, published in Psychological Science, finds that a previously known gene variant can cause individuals to perceive emotional events—especially negative ones – more vividly than others.

    “This is the first study to find that this genetic variation can significantly affect how people see and experience the world,” says Prof. Rebecca Todd of UBC’s Dept. of Psychology. “The findings suggest people experience emotional aspects of the world partly through gene-coloured glasses – and that biological variations at the genetic level can play a significant role in individual differences in perception.”

    The gene in question is the ADRA2b deletion variant, which influences the hormone and neurotransmitter norepinephrine. Previously found to play a role in the formation of emotional memories, the new study shows that the ADRA2b deletion variant also plays a role in real-time perception.

    The study’s 200 participants were shown positive, negative and neutral words in a rapid succession. Participants with the ADRA2b gene variant were more likely to perceive negative words than others, while both groups perceived positive words better than neutral words to an equal degree.

    “These individuals may be more likely to pick out angry faces in a crowd of people,” says Todd. “Outdoors, they might notice potential hazards – places you could slip, loose rocks that might fall – instead of seeing the natural beauty.”

    The findings shed new light on ways in which genetics – combined with other factors such as education, culture, and moods – can affect individual differences in emotional perception and human subjectivity, the researchers say.

    BACKGROUND

    Further research is planned to explore this phenomenon across ethnic groups. While more than half of Caucasians are believed to have the ADRA2b gene variant, statistics suggest it is significantly less prevalent in other ethnicities. For example, a recent study found that only 10 per cent of Rwandans had the ADRA2b gene variant.

    The study was co-led by UBC Prof. Rebecca Todd (as a PhD student at the University of Toronto) and Adam Anderson (Cornell University). DNA samples and genotyping were provided by Daniel Mueller (Toronto’s Centre for Addiction and Mental Health).

    The study, Genes for emotion-enhanced remembering are linked to enhanced perceiving, is available upon request.

    But think of the implications for Positivism and Negativism!

    I don't think it's new information to identify the pattern of this. Maybe identifying specifics... but I though it was common knowledge that things such as depression are passed through genetics... is this so different?

    Now this is a story all about how, my type got changed, turned upside down. Just wait for a minute and watch chatbox right there, & I'll tell how Gem became the moderator with blue hair.

    In typology central friended and praised, on the picture thread was where she spent most her days. Chilling out, selfies, relaxing all cool, And all typing some people and getting them schooled.

    When a couple of girls who were up to no good, Started annoying her & her friends in the forumhood, She got in one little flame war & got pissed off & said 'I'm moving in with that exboyfriend in the forum with the socionics toffs.

    So Gem pulls up to the forum for a year without being a hater, And yells to typocentral 'Yo creeps! Smell Ya later', Became a mod in her kingdom she was finally there, To sit on her throne as the mod with blue hair.

    I reckon people identified to have this genome should be administered psychedelic therapy.

    As long you link depression with neuroticism, it has some merit, for neuroticsm is one of the traits inherited via genes. Same goes for height, weight, arm length, foot length, I.Q, and so on.

    Nah, a shitton of DXM sorted my pessimism out. On the flipside, it might have catalysed a slow spiral into what is conventionally considered in the scientific community to be being an utter fruitloop.
