Making Sense of Bastards

November 23, 2008 in Blogs, Mind Hacks by Vaughan

A 2005 article from business psychology journal Organization Studies discusses the psychology of being a bastard. It has a serious point, but is just hilarious for the contrast between the academic language and the subject matter. The serious point behind the article, written by psychologist David Sims , is to look at how people in business organisations make narratives or stories about someone being a ‘bastard’ to demonize them and persuade others of the fact. This can be to discount someone else opinion, undermine their status, or to create a dragon against which they can valiantly fight for their own glory. However, because of the subject matter, it’s frequently funny as it analyses the varied types of company bastards as they’re constructed within organisations. Just some of the section headings are pure genius: Narrative 1: Clever Bastard Narrative 2: Bastard ex Machina Narrative 3: Devious Bastard A Narrative Understanding of Bastards Making Sense of Bastards Link to ‘You Bastard: A Narrative Exploration of the Experience of Indignation within Organizations’ (thanks Olwyn!).

7 Reasons Leaders Fail

November 19, 2008 in Blogs, PsyBlog by PsyBlog

Around two-thirds of workers say the most stressful aspect of their jobs is their immediate boss, their line manager ( Hogan, 2006 ). While this will come as no surprise to most, this statistic suggests a massive number of unhappy working relationships. So, does this mean that leadership is failing on a massive scale? Well, not exactly… A recent article published in American Psychologist beautifully explains why so many people experience their managers as piping hot geysers of stress ( Vugt, Hogan & Kaiser, 2008 ). What emerges is that bosses aren’t inherently bad people (mostly), but that the modern culture of work sets them up to fail. Here are the seven main reasons I’ve picked out from this article for why leaders fail: 1. Strict hierarchies. For Mark Van Vugt of the University of Kent and colleagues a large part of the problem with many modern organisations is their hierarchies. Leaders are at the top of the chain and are assumed to have all the answers, so they make most of the decisions. In reality knowledge and expertise is spread across people in organisations. But it’s the leaders who must be seen to lead and so followers get frustrated because their superior knowledge and expertise is frequently ignored. This leads to: 2. Poor decision-making. Leaders often don’t make any better decisions than followers, and frequently make worse ones. This is another consequence of strict hierarchies. Rather than setting up leaders to fail, Van Vugt et al. (2008) argue it’s better to agree that leaders are not always the best people to make the decisions. Spreading the responsibility around, or using more participatory strategies for decision-making is often more effective. But this isn’t the way things generally work, part of the problem is: 3. Huge pay differentials. Followers often hate their leaders because of the huge difference in their salaries. It’s hard to feel any sympathy for someone whose pay is stratospheric (average CEO pay is 179 times that of average workers). And, because more pay means more status, leaders can quickly come to believe they really deserve the God-like status their pay suggests, resulting in their thinking they have all the answers and that they have the right to treat their employees less than fairly. In the bosses’ defence, though, there are: 4. Impossible standards for leaders. Perhaps because of the huge pay and incredible demands, followers expect their leaders to be almost superhuman. The leadership literature identifies a whole range of personal qualities thought important for a good leader. These include integrity, persistence, humility, competence, decisiveness and being able to inspire the troops. While a leader may be high on one or two of these, they are unlikely to have the full set. Followers are almost bound to be disappointed by what is, after all, another fallible human who is just trying to: 5. Climb the greasy pole. If the boss is nice to you, it’s a bonus, because it’s not required for them to get on in the organisation. Leaders are promoted by those higher than them, not those below them – so it’s only necessary for bosses to impress their bosses. This is a recipe for disaffection amongst the followers. Talking of which, forget the psychology of leadership, what do we know about the: 6. Psychology of followership? One of the best points Van Vugt et al. make is that although it’s leadership that has been most extensively studied and discussed, most of us end up as followers. So really the psychology of followership is more important than leadership. What is it that makes us follow someone else? And, more subversively: do we need leaders? For example, some research shows that when people know what they’re doing, they resent having leadership imposed on them. Generally, though, there’s little known about followership, and how to avoid: 7. Alienation. As a result of the strict hierarchies, huge pay differentials, poor decision-making, greasy-pole climbing and feeling powerless to change huge bureaucracies, followers naturally develop feelings of alienation, and alienation kills motivation and productivity, along with any hope of job satisfaction. Talk is cheap By implication the way to rectify these perceived problems is to do the reverse. Don’t instigate rigid hierarchies, discourage huge pay differentials, democratise decision-making and don’t set impossible standards for leaders. Some organisations are already managing this – presumably those in which followers don’t find their bosses the biggest sources of stress – but most are not. Of course talk is cheap and recognising the problem is quite different to knowing what to do about it, or having the courage to do it. Anyone wanting to make these types of changes across an organisation would have to be a really great leader – and there are truly few of those around. What do you think? Do you recognise these problems in your organisation? Has anyone tried to do anything about it? Are there other major reasons leaders fail?

Friday Weird Science: Cool Tunes [Neurotopia (version 2.0)]

November 14, 2008 in Blogs, Brain & Behaviour by BrainAndBehaviour

I actually had another piece in mind for this Friday’s Weird Science, but a friend of mine sent me a link to this paper, and I HAD to do it. It’s not just weird, it’s awesome! Long, Fee. “Using temperature to analytze temporal dynamics in the songbird motor pathway.” Nature, 2008. I will start this post with an observation. My brother and I observed, around about the time the movie “Titanic” came out, that you can do “the Macarena” to ANY song. Really. Any song you like. Pick one. Our personal favorite was “My Heart will Go On”, partially because we didn’t like the song. This paper made me think of the Macarena, and how you can do the same sequence of movements to any song written in anything like 4 or cut time (or even 6/8, but you had to get creative). The same sequence of movements can be performed at many different paces. But what controls how fast you perform a particular series of movement? How can you sing “Happy Birthday” at a breakneck pace, and then at the pace of a funeral dirge, all without losing the tune (if you can keep the tune in the first place)? And that is what this article is about. And it’s the way they did it that makes it weird. Read the rest of this post… | Read the comments on this post…

The art of digital synaesthesia

November 9, 2008 in Blogs, Mind Hacks by Vaughan

Artist and researcher Mitchell Whitelaw wrote an interesting and in-depth article on the links between audio-visual fusion art and synaesthesia for the Senses and Society journal. Whitelaw has just put the piece online, has illustrated it with embedded videos of some of the stunning pieces he references, but also discusses the neuroscience of synaesthesia with considerable care and insight. In the age of ubiquitous digital media, synesthesia is everywhere. In human, neurological form, it is rare: for perhaps three in a hundred people, a stimulus in one sensory modality automatically induces a sensation in another. Auditory-to-visual synesthesia, or “colored hearing” is much rarer still. Yet now this phenomenon is realised, apparently, inside every digital music player, on VJ screens in every club, in robot lightshows. On these screens sound is transformed into visual pattern and form instantly and automatically; an exotic perceptual phenomenon becomes a technically mediated commonplace… Synesthesia is widely used as an analogy around this work. The analogy provides a mapping that aligns subjective sensation with audiovisual signals; it maps perceptual or even neurological structures onto technical structures. The analogy also plays another role, foregrounding sensation in the reception of the artworks; proposing to operate, for the subject, at the level of direct sensation… This paper’s main aim is to test this analogy, and the related historical drive that Strick suggests; to consider if, and how, such practice can be thought of as synesthetic, and examine structural parallels between synesthesia as a perceptual and neurological phenomenon, and the automatic or transcoded linking of audio and visual media… The article is quite dense in places but well worth the effort as it carefully picks out whether these digital artworks tell us anything about synaesthesia or are just dropping neurological buzz words to sound cutting-edge. BTW, the image is a still from a fantastic piece by artist Robert Hodgin which is embedded in the article, but which you can also view here .

Through the eyes of the psychopath

November 4, 2008 in Blogs, Mind Hacks by Vaughan

The New Yorker has an engaging article about psychopaths and what psychologists are starting to learn about the psychology and neuroscience of people who are thought to lack empathy. Psychopathy doesn’t necessarily imply violence. The most commonly used modern definition, based on the work of psychologist Robert Hare , suggests that psychopathy includes things like a lack of conscience, manipulative behaviour, impulsiveness and an anti-social lifestyle. The condition was first described clinically in 1801, by the French surgeon Philippe Pinel . He called it “mania without delirium.” In the early nineteenth century, the American surgeon Benjamin Rush wrote about a type of “moral derangement” in which the sufferer was neither delusional nor psychotic but nevertheless engaged in profoundly antisocial behavior, including horrifying acts of violence. Rush noted that the condition appeared early in life. The term “ moral insanity ” became popular in the mid-nineteenth century, and was widely used in the U.S. and in England to describe incorrigible criminals. The word “psychopath” (literally, “suffering soul”) was coined in Germany in the eighteen-eighties. By the nineteen-twenties, “constitutional psychopathic inferiority” had become the catchall phrase psychiatrists used for a general mixture of violent and antisocial characteristics found in irredeemable criminals, who appeared to lack a conscience. In the late nineteen-thirties, an American psychiatrist named Hervey Cleckley began collecting data on a certain kind of patient he encountered in the course of his work in a psychiatric hospital in Augusta, Georgia. These people were from varied social and family backgrounds. Some were poor, but others were sons of Augusta’s most prosperous and respected families. Cleckley set about sharpening the vague construct of constitutional psychopathic inferiority, and distinguishing it from other forms of mental illness. He eventually isolated sixteen traits exhibited by patients he called “primary” psychopaths; these included being charming and intelligent, unreliable, dishonest, irresponsible, self-centered, emotionally shallow, and lacking in empathy and insight. However, the article focuses on the work of psychologist Kent Kiehl who has completed a great deal of recent brain imaging research on criminal psychopaths, and argues that the core problem is a dysfunction of the paralimbic system. This includes areas such as the orbital frontal cortex, anterior cingulate and amygdala, that are known to be involved in emotional reactions and often thought to be involved particularly in social interaction and empathy. However, as the article recounts, getting inmates at maximum security prisons involved in cognitive science research has its own special challenges. Although this seem to have been somewhat mitigated by Kiehl’s use of a portable fMRI machine. To be honest, the article focuses a little too much on the personalities, particularly when the science is so interesting, but it does cover the bases well and does make for an engaging read. Link to New Yorker article ‘Suffering Souls’.

Trans children – trapped in a body, mind or society?

November 3, 2008 in Blogs, Mind Hacks by Vaughan

The Atlantic magazine has an excellent article about the heated issues raised by children who want to be the opposite sex. It’s an excellent piece that captures both the dilemmas of parents and mental health professionals sparked by potentially transgendered children. I sometimes jokingly suggest that clinical child psychology would be better described as clinical parent psychology, owing to the fact that it almost always involves working as much with the parents’ anxieties as the child’s. This is particularly important when it comes to behaviours which are not considered, in themselves, to be physically or mentally damaging, but which are socially unacceptable or stigmatised, because the pressure often takes the form of others wishing the child would conform to social norms. The Atlantic article gives some vivid examples of some of the pressures, as the child, mother, father, professionals, peers and campaigning groups each have different opinions on how to manage a young child that dresses and acts like a child of the opposite sex. As we discussed in a post about an NPR programme that covered the same territory, one of the big controversies is whether to try and treat the child to identify with their birth sex, or whether to help them cope with the stresses of adjusting to life as a transgendered child. This is complicated by the fact that follow-up studies have shown that not all children who have cross-gender desires when young maintain them through puberty. However, hormone treatment exists which can delay puberty so it makes it easier for a child to pass as the opposite sex if this is thought the best course of action. The Atlantic piece is a remarkably well-researched piece that covers a great deal of the mental health debate about the practice and ethics of treating what are known as ‘gender dysphoric’ children, but also gives us a revealing insight into some of the family and social dynamics that affect the individuals. A compelling and thought-provoking insight into this contested area. Link to Atlantic article ‘A Boy’s Life’. Link to previous Mind Hacks piece on ‘gender identity disorder’.

*blink blink* Cocaine? [Neurotopia (version 2.0)]

October 28, 2008 in Blogs, Brain & Behaviour by BrainAndBehaviour

Until I read this paper, I seriously had no idea that spontaneous eyeblink was a clinical indicator for dopaminergic function. I guess this shows you how divorced the pure research side can be from the clinic. But before I cover this article, I must make a plea on behalf of all over-read and over-worked grad students out there: please, if you are going to publish your data (not a review article), PLEASE present your data in a pretty pretty graph. Data tables SUCK. Nobody likes them. I see a paper filled with nothing but tables and I conceive an instant dislike. Perhaps there are some statisticians out there who like them because they can look at it and go “oooh, I notice that your people had a mean cannabis use of 483.3 with an SD of 174.9?! Nifty!” But the rest of us mere mortals like graphs. They are simple, they are clear, and they get the point across. A really GOOD graph will knock your socks off. A table will always make sure your socks stay on. In closing: Graphs = good. Tables = big pile of suck. Moving on. “Reduced Spontaneous Eye Blink Rates in Recreational Cocaine Users: Evidence for Dopaminergic Hypoactivity” Lorenza S. Colzato*, Wery P. M. van den Wildenberg, Bernhard Hommel.

Myths of the sleep deprived

October 16, 2008 in Blogs, Mind Hacks by Vaughan

New Scientist has an interesting piece by sleep psychologist Jim Horne who sets about busting the myth that modern society causes large scale sleep deprivation. It’s full of fascinating facts and uses the phrase “to eke out the very last quantum of sleepiness” which is just lovely. Until recently, people living above the Arctic circle slept much longer in winter than in summer. There are reports from the 1950s of Inuit sleeping up to 14 hours a day during the darkest months compared with only 6 in the summertime. Given the opportunity, we can all learn to significantly increase daily sleep on a more or less permanent basis. When it is cut back to normal we are sleepy for a few days, and then the sleepiness disappears. Far from our being chronically sleep-deprived, things have never been better. Compare today’s sleeping conditions with those of a typical worker of 150 years ago, who toiled for 14 hours a day, six days a week, then went home to an impoverished, cold, damp, noisy house and shared a bed not only with the rest of the family but with bedbugs and fleas. What of the risk of a sleep shortage causing obesity? Several studies have found a link, including the Nurses’ Health Study , which tracked 68,000 women for 16 years ( American Journal of Epidemiology , vol 164, p 947). The hazard, though real, is hardly anything to worry about. It only becomes apparent when habitual sleep is below 5 hours a day, which applies to only 5 per cent of the population, and even then the problem is minimal. Somebody sleeping 5 hours every night would only gain a kilogram or so of fat per year. To put it in perspective, you could lose weight at the same rate by reducing your food intake by about 30 calories per day, equivalent to about one bite of a muffin, or by exercising gently for 30 minutes a week. One of the lessons from sleep research is that we’re actually pretty bad at judging how much sleep we need and even how much we actually get. This seems to be particularly the case for people with insomnia who tend to underestimate the amount they sleep and overestimate the time it takes them to drop off. The article is great guide to sleep myths and how they’re addressed by the scientific research and surprisingly for New Scientist , the article is open-access. NewSci staffer having sleepless nights over their closed-access policy or just someone asleep at the wheel? Answers on a night cap please… Link to NewSci piece ‘Time to wake up to the facts about sleep’.
