Impulsive acts

kid_jump.jpgThe New York Times has an article which examines the sometimes contradictory psychology of impulsivity.

Doing new things is often among lists which promise us ‘ways to happiness’ in magazines and books, and yet problems with impulse control have been cited as a major factor in everything from ADHD to drug and gambling addiction.

One problem for researchers is this type of impulsiveness is not present in every facet of life and can be quite difficult to pin-down experimentally.

One reason true impulsivity has been difficult to capture in the lab, said Dr. Martha Farrah, director of the Center for Cognitive Neuroscience at the University of Pennsylvania, is precisely because “it is most manifest in these very high-stakes situations, when people are trying to get what they want, to stay focused, maybe trying to kick a drug habit.” And that is when they break down.

SciAm online special on The Child’s Mind

SciAmChild'sMindCover.jpgApparently Scientific American have been doing ‘online only’ specials for a while, but they completely passed me by until they just released one on the The Child’s Mind.

It’s a collection of various articles that have been published in SciAm over the past few years on developmental psychology and neuroscience.

The issue is not freely available, it costs $5 to download, but this seems good value for those (like me) not wanting to pay for a full online subscription for issues they might never read.

I quite like the idea of a minimum payment for a one-stop collection of previously published special interest articles and I’m hoping other publishers will consider doing the same.

The special has articles with both clinical and ‘pure research’ angles, including “Why Children Talk to Themselves”, “Scars That Won’t Heal: The Neurobiology of Child Abuse”, “Uncommon Talents: Gifted Children, Prodigies and Savants” and “Think Better: Learning to Focus”.

Fragmented minds part II online

Part II of the Australian All in the Mind two-part series on schizophrenia is now online. The second part focuses on the current range of treatments for people diagnosed with the condition.

This includes both pharmacological and psychological approaches, and the programme discusses the current state of research and the advantages and disadvantages of various therapies.

The programme also explains how many current therapies are attempting to directly address difficulties which have been uncovered by cognitive science research.

Gladwell on Tilly on the sociology of explanations

CharlesTillyWhy.jpgMalcolm Gladwell writes an insightful review of “Why?” (ISBN 069112521X) by renowned sociologist Charles Tilly that tackles the social context and motivations for providing explanations.

A recent article in The Guardian also discussed the new book and summarised Tilly’s five ‘types’ of explanation:

There are, Tilly suggests, at least five different ways to explain why things happen. To take Katrina as the example: the first explanation might be “convention” (there’s always a monumental cock-up after a hurricane); the second, “technical explication” (in which the meteorologists precisely chart how weather conditions created the chaos); third, “codes” (in this case, the federal, state and city ordinances that prevented any clear line of responsibility emerging); fourth, “ritualistic” explanations (God’s wrath or nemesis); and “fifth”, stories.

In Gladwell’s New Yorker review, he highlights the fact that these types of explanations have different social purposes and are typically used to achieve certain persuasive ends in a debate.

Proponents of abortion often rely on a convention (choice) and a technical account (concerning the viability of a fetus in the first trimester). Opponents of abortion turn the fate of each individual fetus into a story: a life created and then abruptly terminated. Is it any surprise that the issue has proved to be so intractable? If you believe that stories are the most appropriate form of reason-giving, then those who use conventions and technical accounts will seem morally indifferent—regardless of whether you agree with them. And, if you believe that a problem is best adjudicated through conventions or technical accounts, it is hard not to look upon storytellers as sensationalistic and intellectually unserious.

Gladwell (who was recently profiled in Psychological Science) makes links between Tilly’s work and the work of the late sociologist Erving Goffman who similarly examined seemingly straighforward social interactions.

In his classic book The Presentation of Self in Everyday Life Goffman argued that how we present ourselves to others is often like a stage appearance, which we try to manage as much as possible to control the impressions that others draw from our ‘performance’.

UPDATE: The first chapter of “Why?” is freely available from Princeton University Press in html or pdf format.

A very modern reality

A poem by John Hegley from his 1993 collection Five Sugars Please (ISBN 0413773000).

Outsider art
As a bit of a break for Albert
from the hospital of the mind
I accompanied him to the park for a picnic
and a bit of crayoning enjoyment;
using just the one crayon
he liked to attend to a piece of paper
and meticulously obliterate the surface area.
Some time into the process
a couple who shared Albert’s middle age
came sneaking a fascinated peek
over the shoulder of what they took to be
an amateur landscape artist
but found his interpretation of reality
just a little too modern.

Football medication

Cipramil_packet.jpgI’ve just found an anomalous appearance of Norwich City Football Club in a commonly used prescribing manual for psychiatrists.

From the entry on p45 for the SSRI anti-depressant citalopram (trade name ‘Cipramil’) in The Psychotropic Drug Directory 2001/02 by Stephen Bazire (ISBN 1856421988):

In patients who had responded to citalopram 40mg/d for four months, halving the dose to 20mg/d for a maintenance phase (2-yrs) resulted in a 50% relapse rate, re-inforcing the view that full-dose maintenance therapy is required (n=50, Franchini et al, J Clin Psych 1999, 60, 861-65). It has a very low incidence of interactions.

The green and yellow 20mg pack in the UK has led to increased use among football supporters in the author’s home city of Norwich.

Art and consciousness

Amarylis.jpgLike a neuropsychological tag-team, the other half of the Brain Ethics blog duo has followed up his partner’s recent Science and Consciousness Review article, with his own on Art and the Conscious Brain.

Martin Skov specialises in neuroaesthetics, the science of understanding how art and beauty is understood by the mind and brain.

Critics sometimes ask if the illumination of neurobiological mechanisms adds anything important to old-fashioned ‚Äì i.e., philosophical ‚Äì aesthetic inquiry. I think that already Plato and Aristotle already answered that. As they pointed out, works of art are created with the express purpose of provoking a mental representation in the brains that experience them. Thus, to understand the nature of art you also have to understand the cognitive processes responsible for turning the perceptual properties of any art object into a mental representation. How colour, lines, etc. are magically transformed into Mona Lisa’s enigmatic smile is very much a question of how the brain works.

Neuroaesthetics is becoming an increasingly popular field in contemporary neuroscience, with an increasing number of books and even regular conferences now devoted to the field.

Update: It looks like Science and Consciousness Review are having some minor connection issues at the moment. Hopefully, normal service should be resumed shortly.

Old spike activities republished

spike_red.jpg

In the old days, our regular Friday spike activity features would be published with the titles such as ‘Spike activity yyyy-mm-dd’.

Unfortunately, the blogging software squashed a month’s worth of these posts down to the same URL, meaning they don’t properly turn up in searches and can’t be linked individually.

We worked this out eventually, and so we started publishing them entitled with the date first, so each have an individual URL.

This didn’t fix the old Spike activities, but I’ve now gone through and re-titled all the old format posts, so they should turn up properly in searches.

The fixed posts are all individually linked in the rest of the post, so have a browse through if you want more links than you can shake an electrode at.

American Scientist reviews the toxicology of legal and illegal recreational drugs.

Sex and relationship psychologist Petra Boyton analyses the science behind recent reports that ‘media exposure encourages teenage sex’.

Cognitive Daily considers some intriguing experimental evidence suggesting that those seeking fame should should avoid the company of those more famous than themselves.

Mixing Memory has a careful and enlightening analysis of the potential role of movitated reasoning in romantic relationships.

A new study suggests that mobile phone use may be linked to malignant brain tumours.

The Anxiety, Depression and Addiction Treatments blog has a concise summary of some of Richard Wiseman’s work on the psychology of being lucky.

Neurochemistry hacker t-shirt

NeurochemistryHackerTShirt.jpgOnline t-shirt mongers Jinx Hackwear have a t-shirt emblazoned with the phrase ‘Neurochemistry Hacker‘ – designed by hacker website Collusion.

I presume they’re thinking of what we might knowingly call ‘amateur brain chemists’ rather than professional neuroscientists or psychopharmacologists, although the idea is broadly the same.

It reminds me of the popular 80s rave t-shirt that had ‘drug testing in progress’ across the front. Perhaps we need something more specific for the neuroscience community.

Maybe selective serotonin re-uptake inhibition or dopamine transporter modulation in progress?

Fragmented minds

MaureenOliverPsychosis.jpgThe other All in the Mind (broadcast by Australian station Radio National) has the first of a two-part special on schizophrenia and psychosis.

The presenter talks to Angela, a young woman who has experienced some intense psychotic episodes and has been diagnosed and treated for schizophrenia.

Angela’s experiences were so severe as to need several years recovery. Despite this, Angela is now back at work and enjoying a full life.

The programme also includes input from several researchers and clinicians who explain what is known about schizophrenia-related changes in the brain, as well as known risk factors for developing the condition.

Part two of the programme is due online next week.

The picture on the left is by artist Maureen Oliver and depicts the experience of psychosis (click for more information).

All in the Mind LSD programme audio online

blue_colour_swirl.jpgA quick update on our previous post on the BBC All in the Mind LSD special. The realaudio archive of the show is now available online (now also linked from the original post).

Furthermore, BBC News has an additional article summarising the programme, and there’s an interesting snippet (i.e. gossip) about the new series from The Telegraph.

Apparently, Claudia Hammond is a “glamorous psychology writer”. Probably, just like us here at Mind Hacks (*cough*).

More on psychedelic therapy

Christian just reminded me that New Scientist had an article last year on psychedelic therapy research which is freely available online.

The article describes a number of recent and ongoing studies into the safety and efficacy of psychedelics for a range of disorders. This is despite difficulties caused by legal restrictions and political resistance to substances typically associated with the ‘counter-culture’.

BBC All in the Mind on LSD

ErowidLSDBlotterArt.jpgBBC All in the Mind has just kicked off a new series with an excellent special edition on the latest developments in LSD research and therapy, and with a slew of new presenters.

The programme examines the science of how LSD acts on the mind and brain, as well as research on the use of psychedelics to treat cluster headaches and mental distress.

It‚Äôs nearly 40 years since LSD was made illegal, but now there’s growing scientific interest in studying hallucinogenic drugs. In the 50s LSD was believed to be a wonder drug and used widely in psychiatry to treat conditions from depression to addiction.

In this week’s programme Claudia finds out about the new research underway using psychedelics, and asks whether modern psychiatry is really the place for drugs like LSD, magic mushrooms and Ecstasy.

There are now three presenters to replace the previous All in the Mind frontman, Raj Persaud.

They include: Claudia Hammond, a psychology lecturer, author and past presenter of the excellent BBC series Emotional Rollercoaster (still archived online); Clinical psychologist and writer Tanya Byron, who was in a number of acclaimed child management programmes; and psychiatrist Kwame McKenzie, who is currently assistant editor at the British Journal of Psychiatry and a lecturer in psychiatry.

The diverse set of presenters should bring a fresh perspective on current mind and brain issues, and I’m hoping the programme is going to involve more in-depth whole programme discussions, as has been demonstrated this week.

The audio of the LSD programme will be archived online later today. I’ll update this page to link to it when it arrives online.

The audio of the programme is now online and linked below.

Why are women’s brains smaller than men’s?

sMRI_small.jpgThe Times has a short piece on the question of why female brains are generally smaller than male brains. The author speculates that it may be because women are generally more pleasant (and smaller in body size).

Surprisingly, the conclusions are largely drawn from evolutionary studies of foxes. Probably not one to take particularly seriously, although an interesting hypothesis nonetheless.

Insanity in focus

BenettonAnaisPortrait.jpgThis is one I missed when it first appeared – the United Colors of Benetton magazine Colors had an issue focusing on mental illness and its treatment around the world.

Despite the flash-heavy website, there’s some beautiful photography in there, including some self-portraits taken by patients (like the one on the right).

The issue features patients from Cuba, Ivory Coast, South Africa, Belgium and Los Angeles, and shows the striking inequalities in mental health treatment throughout both the developed and developing world.

The photographs from Cuba are also currently part of an exhibition at London’s Institute of Psychiatry, where they are contrasted with photographs of patients resident in the Bethlem Royal Hospital during Victorian times.

Many of these Victorian-era photographs from the Bethlem are reproduced in a thought-provoking book called Presumed Curable (reviewed here).
