The Mask of Sanity

hervey_clekeley.jpgThe complete text of the classic book on psychopaths and the psychopathic personality The Mask of Sanity is available online as a pdf file.

The book was written by psychiatrist Hervey Cleckley (pictured on the left) and is one of the classics in the field. It is still highly regarded for its in-depth case studies of psychopaths.

Contrary to most Hollywood depictions psychopaths are not necessarilly people who enjoy causing pain or suffering, but are thought to lack empathy and, therefore, tend to use violence to acheive an end, without concern about the impact of their actions.

There’s further information on psychopaths and psychopathy here for those wanting an introduction.

information_radio_leaflet.jpgPsyWar is a website dedicated to the dark arts of psychological warfare and propoganda.

It has a huge archive of propoganda and psychological warfare material from wars past, including copies of leaflets dropped into enemy territory to persuade soldiers and civilians that they were fighting for a lost cause.

The website also has articles and analyses of the techniques used in times past (including a fasinating article on the use of rumour campaigns) with commentary on their effectiveness and cultural impact.

It is interesting to compare these historical materials, largely created by government departments, with the increasing trend for corporations to provide ‘psyops’ services on a consultancy basis (as previously reported on Mind Hacks).

More recently, PsyWar reports on how psychological warfare is being used in the current campaigns in Afghanistan and Iraq.

The genetics of violence

shadow_fist.jpgThere’s a thought-provoking piece over at Brain Ethics about the role of genetics in violence, and particularly the role of a gene that codes for a type of monoamine oxidase enzyme involved in the breakdown of certain neurotransmitters in the brain.

The post reports on recent research led by neuroscientist Andreas Meyer-Lindenberg that found that variants of the MAOA gene predicted amygdala size, and both the response of the amygdala and cingulate cortex.

Both the amygdala and the cingulate cortex have been strongly linked to emotion recognition, and the cingulate cortex to empathy and anticipation.

It may be that differences in these structures may make someone more likely to react violently in certain situations.

The full story is a little more nuanced that this, however, and you’re best visiting Brain Ethics for more comprehensive coverage and analysis.

Autism a target for ‘cereal box diagnosis’

rice_krispies_autism.jpgIn a somewhat bizarre turn of events, Kellogg’s Rice Krispies have agreed to print ‘autism awareness’ messages on the side of their US breakfast cereal packets in partnership with American lobbying group Autism Speaks.

Autism Speaks is a controversial group in some areas, as they claim to speak for people with autism and tend to use emotional messages (compare with the UK’s National Autistic Society) to promote the idea that autism is a “neurological disorder” and “the nation’s fastest-growing serious developmental disorder”.

Although autism is associated with serious learning disabilities in some, many with autism are quite functional and happy to be autistic, and resent the idea that everyone with autism has a ‘neurological disorder’.

Along these lines, a recent edition of NPR radio show All Things Considered looked at the views of people with autism who argue that we should be aiming to accept people with autism, rather than ‘cure’ them.

Furthermore, the idea that cases of autism are on the increase is controversial, largely owing to the fact that the diagnostic criteria for autism spectrum disorders has significantly widened in the last 30 years (as discussed recently on Mind Hacks) and the knowledge of autistic-like traits has become more common.

The cereal packets contain a list of “a few of the possible early signs” of autism and then encourages people to consult their doctor if they have concerns about their child.

Scientist creates android double of self

ishiguro_self_android.jpgHiroshi Ishiguro, director of the Intelligent Robotics Lab at Osaka University in Japan, has created an android double of himself and intends to use it to give lectures to test how well his creation recreates the ‘presence’ of genuine human interaction.

Ishiguro was recently in the news when he demonstrated a female android he had created which was a copy of a popular Japanese news reader.

One of his main aims is to understand the subtleties of face-to-face human interaction so he can reproduce this artificially and overcome the so-called ‘uncanny valley‘ that makes close-to-human robots seem synthetic and unnatural.

Probe the brain

PBS has a fun flash game where you can recreate Wilder Penfield’s brain stimulation experiments from the safety of your own desktop on a virtual, er, human.

If the anyone actually looked like that, I suspect that having brain surgery to help alleviate epilepsy, or a neuroscientist poking round on the surface of your brain with an electrode, would be the least of your worries.

Lays me down with my mind she runs

side_lightbulb.jpgAn article in last month’s American Scientist offered an interesting theory of why some people are driven to find knowledge – because of the kick of natural opioids in the brain.

Sadly, the article is not freely available online, but the theory is outlined by neuroscientist Professor Irving Biederman in a pdf file he’s put online, and in a summary from Eureka Alert.

The idea is that the moment of finally understanding something causes a release of natural endorphins in the brain, providing a response to knowledge acquisition that conditions us to want more.

In other words, intellectual curiosity may be driven by an addiction to an opioid high.

Biederman’s theory was inspired by the well-known discovery that opioid receptors increase along the ventral visual pathway in the brain – the one that is most strongly associated with recognition and meaning.

At the moment, the theory is still largely speculative, although remains an interesting take on why humans are naturally curious.

It’s like jamais vu never again

SydneyOperaHouse.jpgThe 4th International Conference on Memory is currently in full swing in the beautiful Australian city of Sydney, and there’s been a couple of interesting news reports from presentations on deja vu and jamais vu research.

I’m sure d√©j√† vu is familiar to you, but you may never have encountered jamais vu before. [Thank you ladies and gentlemen, I shall be here all evening].

Although details are a bit sketchy, a report from AFP News gives the outline of an experiment on déjà vu by Chris Moulin and colleagues who used hypnosis to experimentally induce familiarity in participants for information they had not recently encountered.

The 18 [participants] were told that when they were next presented with a word in a red frame, they would feel that the word was familiar, although they would not know when they last saw it. But if they saw a word in a green frame, they would think that the word belonged to the original list of 24.

The volunteers were then taken out of hypnosis and presented with a series of words in frames of various colours. Some of the words were not in the original list of 24 and were framed in red or green. Ten of the volunteers said they felt an odd sensation when they saw new words in red, and five others said this sensation definitely felt like deja vu.

ABC News reports on an experiment on jamais vu (a feeling of unfamiliarity when encountering something familiar) by Akira O’Connor and colleagues that involved asking participants by write down the same word over and over until it started feeling ‘peculiar’.

These experiences were described as being similar to classic jamais vu, as described in the literature on people who have permanent or intense jamais vu as part of a neurological or psychiatric condition.

The abstracts of all the talks are available as one large pdf file, but for convenience, I’ve included the abstracts of the d√©ja vu and jamais vu presentations below the fold.

By the way, if anyone attending ICOM-4 has any photos or reports online, let us know, as it would be great to link to them.

The psychology of stalking

girl_hand_on_head_bw.jpgThe ever excellent ABC Radio All in the Mind has a special edition on the psychology of stalking, investigating the drives and motivations of persistent stalkers as well as the impact on their victims.

In order to better understand stalking, Paul Mullen’s group have categorised people who stalk according to what motivates them. There’s the rejected stalker, usually ex-partners trying to reinstate a relationship. The intimacy seeker, who professes love but is oblivious to their victim’s feelings – people who stalk celebrities usually fall into this category and are the most persistent. There’s the incompetent suitor, who lacks the social skills necessary to establish an intimate relationship; the resentful stalker, who’s motivated by anger and a desire for revenge – they can be very frightening but rarely physically violent. And lastly, and thankfully the most rare, is the predatory stalker – they are driven by sadistic pleasure, their stalking is sexual in nature and often leads to attack.

The British Psychological Society magazine The Psychologist published an article on stalking a few years ago (pdf) also examining this intriguing yet disturbing phenomenon.

On the difficulty of choosing post-neurosurgery words

neurosurgery.jpgThere’s a funny and insightful article in Time Magazine by writer Michael Kinsley on the difficulty of selecting the right words to mark the point when you become conscious after brain surgery.

Kinsley wrote the piece before having surgery to implant a deep brain stimulation device to help alleviate the symptoms of Parkinson’s disease.

To much comic effect, the article discusses his dilemma over choosing something to say to make sure he seems cooly blasé, while not sounding like the surgery has affected his faculties.

Apparently, his surgery went fine but you’ll have to read the end of the article to find out what his first words upon awakening actually were.

The best and worst on the mind

After attending April’s “Who’s the greatest? Minds that changed our minds” debate, and last night’s “From bad to worse: the worst ideas on the mind” debate – both hosted by the Royal Institution, I thought I’d give a quick summary of the results.

In winning order:

Who’s the greatest
1) Aaron T. Beck inventor of CBT
2) Freud
3) Hans Eysenck
4) Karl Jaspers

Worst ideas on the mind
1) Lobotomy
2) Drug company advertising
3) Post-trauma counselling
4) Freudian theory of hysteria

The memory experience season

BBC_memory_screen_logo.jpgThe BBC kicks off a season on memory in a few days that aims to explore the impact of memory on our everyday lives as well as encouraging people to improve their memory to keep it sharp.

The Memory Experience includes a series of TV programmes, radio programmes and web resources that will also attempt to explain the psychology and neuroscience of memory to viewers and listeners.

You can even test your memory online and take part in a national survey of autobiographical memories of people in the UK.

A little more conversation

people_meeting.jpgThe Guardian recently published an article on the effectiveness and concerns about the push to promote cognitive behaviour therapy as a treatment for a wide range of health problems.

Cognitive behaviour therapy is one of the most researched and effective forms of psychotherapy, but there are worries it is nonetheless being oversold as a panacea for things for which there are currently little evidence for its effectiveness.

There is no couch, no “tell me about your childhood/dreams/father”. Barely any mention will be made of her past. Instead, the therapist tries to encourage Katie to rationalise her thoughts now, to see the connection between her feelings and her actions. He tries to recognise unhelpful patterns of behaviour (“I ate a whole loaf of bread, then made myself sick because I felt ugly and fat”) and replace these with more realistic or helpful ones (“I don’t need to binge. I have other ways of controlling my emotions, like calling a friend or going kickboxing). This very practical, proactive approach is rather different from the classic modes of therapy, which one CBT convert describes as “frustratingly fluffy and meaningless” and “encouraging you to feel you are not responsible for your own personal wellbeing”.

But while there are few, if any, mental health specialists prepared to dismiss CBT out of hand, there are a significant number of experts who feel that CBT is being grossly oversold. The primary objection seems to be that it doesn’t work for everybody (not even nearly, say some), and that this one-size-fits-all approach may ride roughshod over more traditional forms of therapy which can be just as – if not more -worthwhile in many cases. A year ago, there was even a debate at the Institute of Psychiatry entitled: “CBT is the New Coca-Cola: This house believes that cognitive behavioural therapy is superficially appealing but overmarketed and has few beneficial ingredients.”
