Mind Hacks

The YouTube drug observatory

An innovative new study has analysed YouTube videos of people tripping on a hallucinogenic plant called salvia to understand the behavioural effects of the ‘legal high’ that is still relatively new to science.

Salvia divinorum is a strongly hallucinogenic plant that has been used by indigenous Mexican shamans for many centuries but has recently become popular as it is legal in many countries.

Pharmacologically, it is fascinating as it seems to have its major effect on kappa opioid receptors. These are not the same opioid receptors that drugs like heroin and morphine work on, so the effects are very different, but it is a completely different mechanism to virtually all other hallucinogenic drugs (only ibogaine is known to have a similar effect on the brain).

Especially at high doses it can have the effect of ‘switching off reality’ causing people to be disorientated and there are now thousands of videos on YouTube of people smoking salvia and experiencing the effects.

However, we know only a little about the plant because it is relatively new to science so a research team at San Diego State University, led by psychologist James Lange, decided to analyse these videos to understand the behavioural effects of the drug.

They created a systematic coding scheme which researchers used when watching the videos. This allowed them both to categorise the effects and check that each viewer was agreeing on what they saw.

After watching 34 videos, each of which was selected to show an entire trip from the initial hit to when the effects wore off, the team categorised the effects into five main groups:

(1) hypo-movement (e.g. slumping into a slouched position, limp hands, facial muscles slack or relaxed and falling down), (2) hyper-movement (e.g. uncontrolled laughter, restlessness, touching or rubbing the face without apparent reason or thought), (3) emotional effects included being visibly excited or afraid, (4) speech effects (unable to make sense, problems with diction, problems with fluency, inability to speak, and having problems recalling words) and finally (5) heating effects related to being hot or heated (e.g. flushed, or user makes a statement about being hot or sweating).

They also noted that the effects of are very quick, starting within thirty seconds of the first hit and wearing off completely in about 8 minutes. They also noted that the environment had little influence on the trip but the number of hits was linked to the amount of speech impairment caused by the drug.

In a previous Mind Hacks post about latah, a curious startle reflex localised to Malaysia and Indonesia, we noted that various videos of the phenomenon were available on YouTube, allowing for some ‘armchair anthropology’.

This is another example of this approach and shows how funny videos uploaded to the net can contribute to the understanding of atypical mental states.

Silent stopwatch

This is just a quick tip for psychologists who want a silent or beepless stopwatch, as they are very easy to make.

Stopwatches are often used when psychologists do neuropsychological assessments as they involve the timing of participant responses. Beeps can sometimes be distracting, especially to people who may have brain injury or might be emotionally disturbed, so many assessments recommend stop watches that don’t beep every time you press a button.

Surprisingly, few actually have this option and I keep seeing online discussions about where to get a silent stopwatch. It’s no coincidence that one of the few that allows you to switch off the beep is most commonly sold with books about psychological assessment.

However, you can make virtually any stopwatch silent very easily. If you unscrew the back – you may need a smaller ‘watchmakers’ or ‘jeweller’s screwdriver’ like this one – on the back plate you can see the the piezoelectric speaker (the circular metal disc – on the left in the image). Just cover it with tape and voila! you have a silent stopwatch.

Cheaper than commercially available devices with silent options and works with every stopwatch I’ve found so far.

Decisions, decisions

The New York Times has a review of a new book called ‘The Art of Choosing’, by psychologist Sheena Iyengar, that tackles the psychology of choice and decision-making. I’ve not read the book myself but the review is very positive and like all good book reviews, it is full of interesting snippets and is worth reading in itself.

I didn’t recognise the author at first but she has done some fantastic work and is responsible for the classic experiment where a stall selling many varieties of jam had more people stop to look but sold little, where a stall with only a few varieties had fewer browsers but when they did stop they were much more likely to buy something.

This is among the many curiosities of decision-making (e.g. we say we want more options but we are consistently happier with our choice when we have only a limited selection) but the book seems to go further and discusses cultural differences in how we make and even define choices:

Take a mundane question: Do you choose to brush your teeth in the morning? Or do you just do it? Can a habit or custom be a choice? When Iyengar asked Japanese and American college students in Kyoto to record all the choices they made in a day, the Americans included things like brushing their teeth and hitting the snooze button. The Japanese didn‚Äôt consider those actions to be choices. The two groups lived similar lives. But they defined them differently.

It seems the book has picked up lots of good reviews so I might have to add this one to the list.

Inner strength

Photo by Flickr user joshjanssen. Click for source Discover Magazine has an excellent piece by Carl Zimmer on the brains of elite athletes and how they have adapted with practice to process movement and the body differently.

There are lots of fascinating aspects to the article, but this particularly caught my eye:

To understand how athletes arrive at these better solutions, other neuroscientists have run experiments in which athletes and nonathletes perform the same task. This past January Claudio Del Percio of Sapienza University in Rome and his colleagues reported the results of a study in which they measured the brain waves of karate champions and ordinary people, at rest with their eyes closed, and compared them. The athletes, it turned out, emitted stronger alpha waves, which indicate a restful state. This finding suggests that an athlete‚Äôs brain is like a race car idling in neutral, ready to spring into action.

Del Percio‚Äôs team has also measured brain waves of athletes and nonathletes in action. In one experiment the researchers observed pistol shooters as they fired 120 times. In another experiment Del Percio had fencers balance on one foot. In both cases the scientists arrived at the same surprising results: The athletes‚Äô brains were quieter, which means they devoted less brain activity to these motor tasks than nonathletes did. The reason, Del Percio argues, is that the brains of athletes are more efficient, so they produce the desired result with the help of fewer neurons. Del Percio‚Äôs research suggests that the more efficient a brain, the better job it does in sports. The scientists also found that when the pistol shooters hit their target, their brains tended to be quieter than when they missed.

There’s an interesting distinction here between what it means to have a quiet mind and what it means to have a quiet brain.

The EEG studies mentioned above found that during skilled athletic performance there were an increased number of alpha waves – electrical brain activity between 8-12Hz (cycles or waves per second) – usually associated with wakeful relaxation. In other words, mental calm.

However, these waves do not necessarily imply that the brain is similarly relaxed. In fact, a study that directly measured the link between alpha waves and the brain’s use of glucose found that more energy was need as alpha waves increased.

This whole brain energy / activity link is a little crude, however, and a more recent study using fMRI – a technique that measures the difference in oxygenated blood – has found increased alpha waves linked to reduced activity in parts of the occipital, temporal and frontal lobes, but with increased activity in the deeper brain areas the thalamus and insula.

In other words, it’s not that the whole brain just becomes ‘quieter’ (although you could say this about some specific areas) but that it seems to reconfigure the distribution of work.

Rather than becoming ‘relaxed’ the brain seem to become more ‘finely tuned’ with practice.

High time for psychedelic medicine?

There’s an excellent article on the history of the Multidiscplinary Association for Psychedelic Studies, an organisation that has done much to bring psychedelic drug investigation back into the mainstream of medical research, in that well known bastion of science journalism, Playboy.

I must admit to being a bit embarrassed when I was caught reading the article as I usually only buy the magazine for the photo-shopped pictures of girls in bikinis.

For people who want to avoid such embarrassment the organisation has put a 10Mb pdf of the article online that is mostly safe for work (artistic depiction of flying topless woman with a statue’s head, wings and pills coming out of her ears – sounds better than it is).

The piece weaves together the history of the organisation with a somewhat alarming account of a young woman with terminal cancer being treated by an ‘underground psychedelic therapist’.

The account itself is quite touching, although the fact there are people going around giving terminally ill patients various powerful and illegal hallucinogenic drugs doesn’t inspire me with a great deal of confidence to say the least. However, it is an interesting look into this phenomenon, which, I have to say, was news to me.

In terms of the use of such drugs in clinical research, the article doesn’t really give a good analysis of the likely advantages and disadvantages of such an treatment (the studies so far are promising but small and poorly controlled) but is an interesting insight into how psychologist Rick Doblin make hallucinogenic drug research cautiously respectable again.

There seems to also be a bit of an upsurge in public interest in the topic over the last few days, with an article in The New York Times and a piece in Scientific American discussing these reality bending compounds.

Breezy people

The Times has an interview with neuroscientist Susan Greenfield, largely to do with the recent political tussles in UK science, but where she uses the opportunity to comment on how computer games are ‘as much of a risk to mankind as climate change’. But wait, the best is yet to come – this part is as beautiful as it is baffling:

She is concerned that those who live only in the present, online, don‚Äôt allow their malleable brains to develop properly. ‚ÄúIt‚Äôs not going to destroy the planet but is it going to be a planet worth living in if you have a load of breezy people who go around saying yaka-wow. Is that the society we want?‚Äù

It certainly is not, and I for one would staunchly defend society against such a malign influence.

To be fair, this is probably a transcription error as Greenfield often talks about digital technology being full of “yuk and wow“, but the delightful phrase has triggered something of a fan club (nothing to do with me I might add) and there is now a hashtag, a Twitter stream, a poster and even a T-shirt.

Although I’ve disagreed with the Baroness on many occasions, it seems she hit the nail on the head with this particular prediction, as it seems that there are now a load of breezy people who go around saying yaka-wow.

UPDATE: This is pure genius.

Corridors of the mind

I’ve just discovered the joy of searching Flickr for photos of psychiatric ward corridors which turns up some amazing images of hospitals past and present, and photos of institutions that are slowly, and sometimes beautifully, decaying.

The great numbers of abandoned hospitals are mostly due to the shutting down of the old monolithic psychiatric hospitals in the second half of the 20th century.

As the buildings were often built as large permanent structures, often with great architectural finesse, many are difficult to knock down or sell, and so have just remained to fade away. Needless to say, they’ve become a regular destination for urban explorers.

There are many striking photos to check out, but there’s one interesting historical shot. It’s a photo of the main corridor in the now closed down Friern Barnet psychiatric hospital on the edges of North London.

The place was built in 1853 and was originally called the Colney Hatch Lunatic Asylum and the building had, so they say, the longest corridor in Europe, which is captured in the image.

As with many institutions of the time, the building, at least on the outside, was very beautiful. It has now been converted into ultra luxury flats called Princess Park Manor, which, as you can see, has a swish website to match.

So swish, it seems, that despite lauding the architectural heritage the building, it neglects to mention that it used to be one of London’s biggest asylums.

Hacking toy EEGs

Frontier Nerds has an excellent guide to toy EEGs (the commercially available ‘mind control’ games) and detailed instructions on how to hack the MindFlex to use it as a brain-computer interface.

In the last year or so, numerous ‘mind control’ games have appeared that are essentially cheap consumer EEG devices with a dull as ditch-water games attached. For example, the ‘Force Trainer‘ reads off EEG signals and levitates a ball. Yes, that’s it.

There are developer’s kits available for some of the products but they tend to be quite expensive. Frontier Nerds realised you can buy a cheaper model and with a little messing around can pull the data right off the electronics.

Even if you’ve no intention of hacking any of these devices, the piece is an interesting look inside the construction of these toy EEGs.

As we’ve mentioned before, it should be possible to do some serious science of sorts with these devices.

Because the data is so noisy, almost all EEG experiments, even in the best equipped labs, get people to do the same thing over and over and then average the signals to filter out the noise. This is why EEG experiments can be a bit dull to take part in as there tends to be lots of repetition. In a second stage each person’s EEG signals are averaged together to get an overall effect.

You could potentially have an internet-based experiment that uses these devices which people can try at home, and with a large enough data set, get a reliable result.

It won’t have the precision of a lab-based set-up, but it could still be useful.

Social warfare

A news story in today’s Nature notes that the US military are pumping more money into social science research which is considered to be an important ‘game changing’ component of 21st century warfare.

The unconventional wars now being fought by the US military have also bolstered interest in the social sciences. With the military trying to stave off a growing insurgency in Afghanistan, the Pentagon now believes that understanding cultural dynamics is at least as important as weapons. Consequently, Lemnios is ramping up funding in social-science projects, including a model developed by Los Alamos National Laboratory in New Mexico to simulate the opium trade in Afghanistan and analyse the effectiveness of efforts to combat it. The office is also supporting a project at the University of Chicago, Illinois, to model and predict potential conflicts.

Research to be used ‘on the ground’, like that described above, is likely to involve at least two important components. The first is the deployment of social scientists in conflict zones to use their skills to better solve problems that require the co-operation of local populations, along the lines of the Human Terrain System.

The other is the use of mathematical modelling to look at the structure of social networks to decide who are the key players or to infer (technically, to impute) the likely structure of the network that is not directly known about.

For example, within a large town there may be a small network of insurgents / terrorists / freedom fighters (take your pick) who your army wants to destroy. The traditional approach involves getting informers to reveal this network while you have to make a subjective judgement about how true this information is and how important each individual is, often before blundering in with troops, much to everyone’s alarm.

With social network analysis, you can create maps of the known network and mathematically analyse it for how accurate it seems and get an estimation for how important each person is for the overall structure. You can even add to the model with observational data (e.g. with traffic analysis – looking at communication patterns without knowing content) and make computational best guesses as to relationships and people you know must exist, but no nothing directly about.

The idea being that you can destroy the network by taking out the key people with the minimum of fuss – where ‘taking out’ could mean killing, arresting or bribing, and where ‘fuss’ could mean violence, risk or public knowledge.

Essentially, you are analysing the behaviour of networks and much the same principles (and indeed, some of the same laws) apply to other sorts of networks like transport and communication.

While this sort of research would help forces on the ground, other research, as funded by the Pentagon’s Minerva programme, seems aimed more at foreign policy and PsyOps operations, where the attitude and behaviour of very large populations need to be understood.

As has been the case with previous military enthusiasm for such ventures, this new level of funding is likely to cause additional concern that social science will become ‘weaponised’ and distort a field that has traditionally had a commitment to a ‘do no harm’ policy.

The Nature article also has a curious bit where it discusses the Pentagon’s interest in “how organisms sense and respond to stimuli ‚Äî such as chemicals, ions and metals, or electrical, magnetic, optical and mechanical impulses” to be able to develop “living sentinels”.

UPDATE: Thanks to Ian for sending a link to this Slate article series on ‘how the U.S. military used social networking to capture the Iraqi dictator’.

From madhouse to mainstream

It’s not often that historians are described as kicking ass, but the latest issue of the The Lancet has a barnstorming piece by Andrew Scull that gives an uncompromising history of psychiatry from the mad house to Big Pharma.

It must be said that the article is oriented more toward American psychiatry. Although similar influences have been present in European psychiatry, it has been much less subject to, shall we say, the mood swings that have tended to pull the American psychiatric community from one extreme to the other over the last century.

Nonetheless, it is a rollicking read from one of the most respected historians in the field. This is where Scull discusses the rise of neurobiology:

The US National Institute of Mental Health proclaimed the 1990s ‚Äúthe decade of the brain‚Äù. A simplistic biological reductionism increasingly ruled the psychiatric roost. Patients and their families learned to attribute mental illness to faulty brain biochemistry, defects of dopamine, or a shortage of seratonin. It was biobabble as deeply misleading and unscientific as the psychobabble it replaced, but as marketing copy it was priceless. Meantime, the psychiatric profession was seduced and bought off with boatloads of research funding. Where once shrinks had been the most marginal of medical men, existing in a twilight zone on the margins of professional respectability, now they were the darlings of medical school deans, the millions upon millions of their grants and indirect cost recoveries helping to finance the expansion of the medical-industrial complex.

One of the best articles on the history of psychiatry I’ve read for a very long time. No stone is left unscorned.

Neurodemonology

There is a long-standing myth that before the Enlightenment, all the experiences and behaviours we would now classify as madness were thought to be due to demonic possession.

This idea has been comprehensively debunked and it is now clear that both of these concepts have run side-by-side and medieval courts often went to great lengths to try and distinguish the two ‘states’.

I’ve just read a fascinating article about ‘Demonology, Neurology, and Medicine in Edwardian Britain’ from the Bulletin of the History of Medicine that showed that this tendency continued well into the modern age.

Evangelical demonologists, some of them qualified doctors, incorporated medical advances into their theories – even using the dramatic discoveries of the ‘father of neurology’, John Hughlings Jackson, as a way of better ‘explaining’ our susceptibility to malign influence:

The Jacksonian hierarchy of higher conscious levels, the sensory midbrain, and the lower reflex centers was mapped onto the Pauline division between spirit, soul, and flesh and the psychological division between the supraliminal, the subliminal, and the body (cf. 1 Thess. 5:23 and Heb. 4:12). As Penn-Lewis argued, the lower nervous centers of the midbrain and the medulla could be seen as corresponding to habit and nature, “the law of the organs,” which frustrated man’s attempt to serve God.

This association of the soul with unconscious animal instincts revealed its vulnerability to the possibility of demonic infection. Indeed, many late-Victorian authors had argued that the newly discovered subconscious or unconscious mind provided the perfect medium for demonic activity: connected in psychology and literature to dreams, instincts, passions, and madness, it was seen as a gaping wound in the human personality through which invasive agents could undermine their hosts. Certainly many demonologists believed that invading spirits possessed a natural appetite for nervous tissue as they sought to recapture the nourishing somatic form they had lost.

This is a common pattern, of course. Carl Sagan’s book famously described science as “a Candle in the Dark” against a “Demon-Haunted World” but less attention is paid to the fact that every new illumination casts a whole new set of shadows for people to misinterpret.

No dark sarcasm in the classroom

The Frontal Cortex reports on an interesting study that found that the personality characteristics teachers define as creative are the same ones that make their pupils least likeable in the classroom.

Eric Barker recently referred me to this interesting study, which looked at how elementary school teachers perceived creativity in their students. While the teachers said they wanted creative kids in their classroom, they actually didn’t. In fact, when they were asked to rate their students on a variety of personality measures – the list included everything from “individualistic” to “risk-seeking” to “accepting of authority” – the traits mostly closely aligned with creative thinking were also closely associated with their “least favorite” students. As the researchers note, “Judgments for the favorite student were negatively correlated with creativity; judgments for the least favorite student were positively correlated with creativity.”

This shouldn’t be too surprising: Would you really want a little Picasso in your class? How about a baby Gertrude Stein? Or a teenage Eminem? The point is that the classroom isn’t designed for impulsive expression – that’s called talking out of turn. Instead, it’s all about obeying group dynamics and exerting focused attention. Those are important life skills, of course, but decades of psychological research suggest that such skills have little to do with creativity.

This is a classic example of the conflict where an institution that imposes strict group standards of behaviour claims to promote individuality and self-expression.

A lovely study published last year in the Journal of Personality and Social Psychology demonstrated how people who don’t go along with a task for justifiable moral reasons are typically rejected by the group, even when the individuals in the group might otherwise agree with their moral stand.

In other words, we like rebels as long as they are not bothering us.

Heart breaker

It seems you’re more likely to die from a heart attack when having sex while having an affair, than during sex with your regular partner, although this seems largely to apply to men.

A case report in the Journal of Forensic and Legal Medicine reports on the death of a woman who had a heart attack during extra-marital sex, something unusual in women. This is not conclusive evidence for the link between heart attacks and affairs in itself, of course, but the article reviews some suggestive evidence about sex, risk of death, physical and psychological stress.

Recent studies dispute early popular belief that sexual activity necessitates extraordinary physical effort, by showing that in normal settings, healthy adults show only mild to moderate increases in heart rate and blood pressure. However, this is not the case in individuals suffering from cardiovascular pathologies [heart problems], in which the relative risk of myocardial infarction [heart attack] in the two hours following sex increases 2.5-fold over the baseline. Furthermore, all reported cardiac deaths surrounding sexual conducts involved extramarital sex, suggesting psychological stress as an added factor.

However, as there is no data about behaviour, it’s not clear that psychological stress is the primary thing that increases risk, or whether people are just doing more strenuous things in their extramarital trysts.

The paper does mention one study from Israel, however, that sets the scene, and largely rules out the fact that this may be due to taking Viagra, which can put a strain on the heart

Between the years 1999 and 2008, the National Center of Forensic Medicine in Israel (population of 7.4 millions) investigated at least one case annually of sudden death of a male engaged in sexual activity. All these events took place with substantially younger women, in extramarital settings… In only one instance the toxicological examination revealed traces of sildenafil [Viagra] in the blood.

In all of the cases in this study, the cause was sudden heart failure in men with coronary heart disease.

On the outer limits

The latest edition of RadioLab discusses the limits of endurance, human memory and artificial intelligence in a particularly good programme from the top tier science show.

The section on human endurance looks at the competitors in the Race Across America, an 800km bicyle race where the cyclists sleep on an hour or two a night and eventually start hallucinating as they race.

The story of Mr S, a case of someone with a seemingly limitless memory who was documented in A.R. Luria’s book The Mind of a Mnemonist, is compared with modern day memory competitors. And an AI system that derived a mathematical law that we don’t understand tests the limits of science.

Not to be missed.

Psychosis podcast and the Mind Hacks recursion

About a year ago, we posted about a study at the University of Manchester who were evaluating the impact of podcast about psychosis on attitudes towards unusual mental states. Mind Hacks readers formed a large bulk of the participants and the paper has just been published in the journal Psychosis.

So, in possibly one of the most recursive posts you’re likely to read for a while, I’m going to write about a study you were part of because you read about it on Mind Hacks.

The research was motivated by the fact that although anomalous psychosis-like experiences are common (for example, about a third of people report naturally occurring hallucinations) those who end up in front of mental health professionals are more likely to have assumed that these psychological distortions are uncontrollable, unacceptable or dangerous.

Imagine if you started occasionally hearing voices. The majority of people who hear voices don’t become mentally ill, they’re absolutely fine. But if you didn’t know this you might automatically think you were ‘going mad’ or ‘losing your mind’ and become, understandably, very distressed.

Of course, voices can be a symptom of mental illness but headaches can be a symptom of a brain cancer and imagine how you’d feel if you assumed that every headache meant you had a tumour.

Importantly, there is evidence that distress from worry about unusual experiences can actually worsen the mental state, making it more likely that the person becomes mentally ill.

Ideally, we’d want everyone to know that unusual experiences, like headaches, can be normal but to go to the doctor if they are causing any sort of interference or difficulty.

Unfortunately, most people don’t know this and getting the word out is hard, so the team at Manchester decided to run a pilot study to see if a short podcast that gave good advice would help, so they set about evaluating it.

They asked people to complete some psychological questionnaires online that measured attitudes to hearing voices and attitudes to feeling paranoid, asked people to listen to the podcast, and then return to complete the questionnaires again afterwards.

I have to say, the podcast was not the most gripping and the sound quality could have been improved but despite this, after listening, participants were more likely to accurately rate how common unusual experiences are reported less negative and distressing attitudes towards voices and paranoid thoughts.

As the researchers note, to understand whether this was genuinely an effect of the psychosis podcast, rather than just spending 30 minutes relaxing with an mp3 player, they’d need to run a control group who listened to something else, but this is a promising start and they hope to take the project further to develop a useful mental health education tool.

This is also the first time Mind Hacks appears in the medical literature. The paper mentions Mind Hacks, quotes our entire post, and links to us:

The authors of a popular high-quality psychology blog (http://www.mindhacks.com) also kindly agreed to mention the study to their readers in a short internet post.

So forget your hit counts and blog rankings, the claim that Mind Hacks is a “popular high-quality psychology blog” is now SCIENTIFIC FACT! Although, largely of course, because of you. Researcher Paul Hutton also asked us to pass on his thanks to you all, and we can only do the same.
