• Dr Jack on Body Language (part 2 of 2)

    Springing a Leak

    Although we can voluntarily move our faces around at will, pulling whatever facial expressions we want when called upon to do so, there are other automatic physiological responses generated in the body by emotions that we can’t control.

    eye-contactWe betray our true feelings through body language all the time. When we lie, our awareness that we are doing wrong produces feelings of guilt (in most but not all people), which in turn “leak“ out into the outside world through various aspects of body and voice. Whether we are feeling comfortable or stressed. Whether we are feeling confident or timid. Even aspects of our personality are advertised to our immediate environment through our body language.

    At the same time that we are constantly leaking information into the outside world through body language, information that subtly betrays our true feelings, there are many body positions that we assume and actions that we perform which have nothing to do with our current feelings whatsoever.

    Beware Lone Rangers

    Sometimes we scratch our nose just because it is itchy, and it has nothing to do with whether or not we are lying. Just a spurious coincidence. Sometimes we put our hand to our mouth simply because we’re stifling an unfortunately-timed belch, any apparent relevance to the words just uttered entirely coincidental. The point here is critical – there is lots of noise in the body language signal. The secret to decoding the signals properly is to keep the P.I.C. in mind and never allow a lone indicator to skew your thinking.

    Dr Jack’s A-H of Body Language

    Here’s my A-H of Body Language signals (with guidance for avoiding giving confused signals in parentheses) :

    A – Appendages (uncross arms & legs, plant feet squarely on floor, keep your hands in view / suppress urge to fidget)

    B – Body Posture / Tension (sit up straight, alert, edge of your seat to open diaphragm, breathe deep to reduce stress)

    nod1C – Contact (beware the limp hand shake – grasp palm to palm)

    D – Dress (what you wear speaks volumes about you, invest wisely in a suitable outfit that blends in to the particular work environment)

    E – Eyes (listen with eyes; professional triangle of gaze: eye, forehead, eye; don’t look away too much; not looking = not listening)

    F – Face (pulling a smile = friendliness, frown = hostility; smile to show you are friendly and mean no harm, but don’t over do it!)

    G – Gestures (amplify your words with firm gestures. Get in the Goldilocks Zone: not too much, not too little, but just right)

    H – Head (Active listening involves plenty of eye contact but also nodding [slow→fast] to show you: are following → agree → want to speak)

    Over the next few weeks look for these critical sites of body language in the people around you whilst traveling, in restaurants, pubs, bars, offices, meeting rooms and in your home. The more you study it the more aware you will become of the feelings of the people around you. The more you increase your awareness of how body language betrays true feelings in others, the more you will start noticing yourself betraying your true feelings to others. As your awareness of your own body language and that of others increases you will not only get better at detecting deception in others but you will be able to communicate more effectively yourself by ensuring that the visual, auditory and linguistic components line up so that you come across as confident, competent and trustworthy.

    Origins of Body Language

    The human brain became much, much larger than our primate cousins as we began living in larger and larger groups. And over these many thousands of years certain areas of this expanded brain real estate became specialised to improve our abilities to communicate with each other. We now have brain networks specialised for creating and understanding speech, but also others that discern eye gaze direction and movements, another territory for perceiving faces, yet another involved in registering body parts and even several involved in trying to deduce what a person is really thinking.

    More effective communication would likely have been the foundation for stronger, broader allegiances which in turn enabled pre-human species to enjoy a greater ability to read between the lines. This probably increased likelihood of survival amongst these creatures leaving the less sophisticated communicators in their wake. In this way the human brain would have evolved according to a selection pressure on communication abilities to equip the human race with increasingly sophisticated social skills whilst competitors without the ability to read true intentions from voice and body language perished.

  • Review: High Society at the Wellcome Trust Collection by Dr Jack Lewis

    Henry Solomon Wellcome was well ahead of the game when it came to the “Mo-vember” look for a charitable soul

    With just one week to go before it closes (Sun 27th Feb 2011) I visited the “High Society” exhibition at the Wellcome Collection in London yesterday so that I could review it here in case you were curious.

    I would like to state for the record that I LOVE THE WELLCOME TRUST and would rate Henry Wellcome in my top 5 heroes of all time. His enormously generous philanthropic endowment has turned into a fantastic instution built on sound priniciples that have withstood the tests of time.

    Not only does the WT fund an enormous amount of British scientific research (my PhD included – during which my scientific approach was gradually sculpted under the influence of many extraordinary neuroscientists; most of whom were also Wellcome Trust funded), but it also takes it’s role in public engagement with science, a subject very close to my heart, extremely seriously.

    This commitment to spreading the good word of scientific innovation old and new is, I believe, deliciously exemplified by the special exhibitions that rotate through their space on the Euston Road a few times per year to showcase an interesting area of scientific enquiry. These exhibitions beautifully complement the tone set by the permanent collection upstairs: ancient medical tools, scientific relics and other treasures from the history of medicine; not to mention some outstanding fashion photography modelled by good old Henry himself.

    In late 2010/early 2011 the show space addressed the issue of mind-altering substances. From the outset the visitor couldn’t help but be impressed upon that these chemicals have been popping up throughout history everywhere, for millenia. Drugs of various description have been consumed in one form or another across ALL cultures of the world. And the vehicle for explaining this was a lovely collection of drug paraphernalia from all over the globe and a whole bunch of amazing facts about the drug trade both medical, illicit and sometimes both.

    Psilocybin is a hallucinogenic substance found in certain species of mushrooms

    The free exhibition included a 6th century BC embossed tablets from the Middle East describing some of the medical uses of Cannabis sativa, ornately decorated tobacco pipes, ancient betel nut cutters, indian and chinese opium pipes right up to the modern day DIY crackpipe (comprising a small water bottle, a biro casing and some perforated tin foil).

    These drug taking curiosities, collected from all corners of the earth, may well have encouraged spectators to consider why human beings everywhere are so keen to experiment with mind-stimulating (or mind-depressing) substances in spite of the potential dangers, for instance, picking the wrong mushroom and popping your clogs.

    People expecting an exhilarating experience may have been disappointed. I personally believe it is always important to arrive at an event free of the burden of overly-high expectations. And it worked just fine for me as there were some real treasures within.

    Shockingly heroin was once sold by Bayer pharmaceuticals as an everyday medicine

    Highlights for me included some of the black and white footage documenting Andean Indians drinking the potently hallucinogenic ayahuasca extract (which immediately makes a person vomit and is deemed to be a good thing… helping to purify body and soul prior to entry into the “other” world) provided a fanastic account of how, why and where these indigenous tribespeople enter into this ritual.

    Also the footage of a 1950’s experiment in which a “terribly posh” doctor tests a volunteer before and after consumption of the hallucinogenic drug mescaline. I thought it was very amusing that he was considerably better at counting down from 100 to zero in blocks of 7 (i.e. 100, 93, 86, 79 etc) when he was tripping compared to before he had taken any drug. Also amusing (to me at least) was the way he answered all questions from the battery of cognitive tests directly in a very authoritative manner, yet failed absolutely to find suitable words to describe the gorgous array colours that were hallucinogenically tinting his vision and no doubt also inducing his huge grin.

    Scandalous: when our plentiful supplies of silver and gold were no longer worth what they were the British Empire got China hooked on opium so that we could trade that instead!

    It was also very interesting to get an insight into some of the details of the Opium Wars in which the British used Afghani opium to get the whole of East Asia hooked on smack as a solution to plummeting gold and silver prices leaving them with no barganing chips with which to trade. An absolute scandal of which I had no prior knowledge. There was also an ingenious installation involving various projectors and light filters beaming amorphous colours and shapes onto a large screen that I could have watched for hours – very relaxing.

    The sillhouettes are spectators standing in front of the projectors, not part of the trippy art installation – or are they?

    And on the way out I found the large graphical representations of the relative yearly global turnover elicited from trading legal versus illegal drugs of recreation very interesting – as the relative size of the cannabis versus cocaine versus opiate markets are not as you might expect, particularly when compared to the computer game or pornography markets. Another large graph that effortlessly conveyed a lot of information in a very straightforward, user-friendly manner depicted the gradually declining purity and increasing costs of cocaine as goes from being picked and processed at source, moved from Andean regions to the Carribean, imported into the UK and then sold to the end consumer. It seems that the biggest jump in the cost per kilo occurs, not surprisingly if you think about it, when it enters the country in which it is to be sold, the suprise comes when it is revealed that the hike in cost from before to after is a whopping 600%.

    This ball of opium is the size of my fist!!

    In conclusion it was an eye-opening and fascinating excursion into the world of illicit drugs through the ages showing how our interest in them across all cultures has always been there and will probably always remain.
