Neuroplasticity, evidence from rats and monks

The green box contains a brand new rat neuron. Why is this important? Well, until quite recently researchers were unsure of two things: whether it’s possible for the brain to change and whether it can grow new cells. With the help of rats and monks, the answer is emerging: quite possibly yes.

This phenomenon is called neuroplasticity and is all the rage in neuropsychology at the moment. As none of us are getting any younger, it’s good to know our brains still have the capacity for change.

Alexander Shulgin, the godfather of Ecstasy

Ecstasy’s emergence as a popular recreational drug can be traced back to one man. Although the drug was first synthesised by Merck in 1914, it was initially thought to be useless, and immediately forgotten. It wasn’t until 1976 that an eccentric chemist, Alexander Shulgin (above), resynthesised it on the suggestion of a former student.

Shulgin wasn’t particularly impressed with its effect, describing it as being like “…a particularly lucid alcohol buzz,” but he did find that, “It opened up a person, both to other people and inner thoughts…” He wondered if perhaps it would be useful in psychotherapy and recommended its use. By the late 70s a number of therapists were encouraging their patients to use it – and with some success. In the following decades word eventually spread, and its recreational use began to take off.

Meanwhile Shulgin continued to research hallucinogens, synthesising and testing them first on himself, then on his wife and friends. He carefully catalogued the effects of every single one in his self-published works, ‘Phenethylamines I Have Known and Loved,’ and ‘Tryptamines I Have Known and Loved’.

Unsurprisingly, Shulgin has now become a hero of the counter-culture.

Beliefs about alcohol predict binge drinking

With changes proposed to the licensing laws in the UK there’s been lots of talk about binge drinking. The suggestion is that opening the pubs and bars at all hours will encourage binge drinking.

This is the same as saying that increasing the number of gyms will make us more healthy, or lowering the price of sofas will make us more lazy, or paying lawyers the same as binmen will decrease their number and make us less litigious and argumentative.

The answer to all these: it might but it won’t necessarily.

Research carried out on students into binge drinking – and after all these guys are professionals – suggests that it has much more to do with our expectations for drinking. The student’s belief that it made them more attractive, socially inviting and articulate, was directly predicting how much they drank.

Remember, reality is often not as important as our beliefs in affecting our behaviour.

Graphology has zero validity (it’s rubbish)

According to this report on BBC News there are 3,000 businesses in the UK that use graphology (handwriting analysis) as part of the recruitment process. I am astounded.

Back when I was at school, I had an English teacher who was learning graphology. She took a look at my scrawling and told me that I was becoming more outgoing. I was astounded, how could she tell that just from handwriting? Then she stopped, looked at it again and corrected herself. Or, she said, perhaps it’s the opposite.

Obviously this is only anecdotal evidence, but what else is there? Well, after reviewing the research, the British Psychological Society has ranked all the procedures used in personnel selection in order of validity. Graphology shares its ranking position with astrology: zero validity.

So if your organisation uses this as a method of selecting new recruits, and you don’t work for the British Institute of Graphologists, then it’s time to think again.

Removing barriers to safe motoring

It’s a kind of back to basics approach for motorists. In these experimental stretches of road, gone are road markings, curbs, traffic islands, barriers and even traffic lights. Instead we encourage drivers, pedestrians and cyclists to interact and be more aware of each other.

The idea is so attractive, I hope it works – evidence is encouraging from the UK village where it has been trialled.

Computer use good for literacy skills

This study tested what effect computer use by students had on reading and writing skills. Surprisingly student’s use of a computer during the school year improved their scores in the final test. That was despite it not involving a computer.

A more entertaining finding was buried in the middle. The researchers found that the use of Powerpoint to create presentations actually lowered the student’s marks in the final test. So Powerpoint is as bad for presenter as it is for the audience – something I had always suspected.

Crazy in love

A US company is selling this bear in a straight-jacket ahead of Valentine’s Day. Naturally some priggish Americans have claimed it stigmatises mental illness. Fortunately executives at The Vermont Teddy Bear Co. have taken, and I quote, “the difficult decision,” to continue selling the bear despite the outraged complaints. A triumph of capitalism over political correctness, I’m sure you’ll agree.
