New experiment!

I hope you are well. I have just launched a new study focused on mind reading, and it would be great if you could take part. It takes about 9 minutes and is best carried out on a laptop or computer. All you have to do is click here.

Many thanks and feel free to spread the word!

Festival of Ideas

The University of Hertfordshire have just launched a great online Festival of Ideas. There’s lots of amazing and wonderful content focusing around how the arts and sciences can help to tackle Covid-19, and thoughts about how the world will change post-virus.

I have contributed a talk about the making of a free online computer game that encourages social distancing. The game was created with Martin Jacob and can be played here.  The game received lots of media coverage, made the BBC national news and went viral. We have now had over 75,000 people play it and the feedback has been amazing!

10 tips to Improve your sleep

A report out today suggests that many people are struggling to sleep right now.  A few years ago I wrote a book about the science of sleep called Night School, and here are ten top tips.

Avoid the blues: When your eyes are exposed to light, your brain produces less of the sleep-inducing hormone melatonin. Some research suggests that light towards the blue end of the spectrum is especially stimulating and computer screens, tablets, smartphones and LED lighting all emit a lot of blue light. Try not to use these devices in the two hours before you go to bed. If you must use them, turn down the brightness or wear amber-tinted glasses designed to block blue light.

Avoid nightcaps: Although a small amount of alcohol helps you get to sleep more quickly, it also gives you a more disturbed night, increases the chances of snoring and disrupts dreaming. Don’t drink alcohol in the hours before bed.

Remember the 90-minute rule: Every night your brain goes through several 90-minute sleep cycles. You feel good if you wake up towards the end of a cycle because then you are closest to your normal waking state. To increase the chances of this, decide when you want to wake up and then count back in 90 minutes blocks to discover the best time to fall asleep. For instance, if you want to wake up at 8am, you should aim to fall asleep around either 11pm or 12.30am.

Distract yourself: Research suggests that you will fall asleep quickly if you tire your mind. Try counting backwards from 100 in threes. Or, if you’re not good with numbers, think of a category (countries or fruit and vegetables) and then come up with an example of that category for each letter of the alphabet. A is for Albania, B is for Bulgaria, or A is for apple, B is for banana, etc.

Make a list: Are you struggling to fall asleep because you are worrying about a problem, or thinking about what you need to do the next day? Put a notepad on your bedside table and, before you nod off, make a list of what’s on your mind or make a to-do list for the next morning.

Try staying awake: If you want to nod off, try to keep your eyes open and stay awake. Oddly, attempting to stay awake is surprisingly tiring and helps you fall asleep. But remember that you have to use the power of your mind – you must try to keep your eyes open (you are allowed to blink), but are not allowed to read, watch television, or move about.

Condition yourself: Russian psychologist Ivan Pavlov famously rang a bell each time he presented a dog with food, and eventually found that the sound of the bell alone was enough to make the dog salivate. The same concept can help you to fall asleep. Choose a soporific piece of music that you like, and fall asleep with it quietly playing. Over time, your brain will associate the music with sleep, and simply listening to it will help you nod off.

Get up!: If you’re awake for more than about 20 minutes during the night, get out of bed and do some form of non-stimulating activity, such as working on a jigsaw or a colouring book. This helps to prevent you associating your bed with sleeplessness. And if the problem arises later in the night, climb back out of bed and distract yourself again.

Relax: Lying awake makes many people feel anxious, and this anxiety disrupts their sleep even more, creating a vicious cycle. If you are struggling to sleep, remember that you are probably getting more sleep than you think (research shows that we all underestimate how much of the night we spend sleeping) and that just relaxing in bed is good for you.

Relaxing music: A few years ago I worked with composer Cameron Watt to use scientific principles to create a very relaxing piece of music. Lots of people have reported finding it helpful and it is free to listen to here:

A version of these tips originally appeared in an article that I wrote for The Guardian, and in a previous blogpost. I hope they help!

Can you save the world?

[image error]

I am delighted to launch the first social distancing computer game! Called ‘Can you save the world?’, the game is designed to get children (and adults!) to socially distance, and to also appreciate how this helps to save lives.

I have been working on this with the very talented game designer, Martin Jacob, and you can play it on your laptop or desktop computer for free here.

Enjoy!

 

 

The future of live events

This post was jointly written by Richard Wiseman and Simon Gage (Director, Edinburgh International Science Festival).

The Coronavirus has made large gatherings impossible at the moment, leading to the cancelling and postponement of lots of live events (including concerts, festivals, shows and talks). Obviously, right now it is vital that everyone observes the lockdown and stays indoors. However, even when restrictions are lifted, large gatherings are likely to prove problematic. Given that this situation may continue for many months, we thought that it would be good to start to brainstorm innovative ways of delivering live content. Live performances will inevitably have to change and so this can be seen as an opportunity to develop new and innovative approaches.  Our background is in science communication, and so the ideas are grounded in that area, but the same general approaches would work for a broad spectrum of live events.

Virtual performances: One obvious approach is to move online, and many performers and speakers have already started to do this. Although this has the advantage of scalability, it’s quickly becoming a crowded marketplace, risking screen fatigue. In addition, digital delivery can be challenging when it comes to generating a genuine sense of connection and engagement.

Streets and gardens: Performers could head onto streets and into gardens, and have audiences watching at a distance and/or through their windows.  Two-way chat could happen via the performer using a hands-free headset and a mobile phone to call people indoors (perhaps with the spectators placing their phone to speaker mode).

Drive-ins: In drive-ins cinemas, people watch films from inside their cars. Exactly the same could happen with live events. People could listen via large speakers, the radio, Bluetooth or a mobile device.

Floats: In some towns, Santa Claus is driven around on a float and everyone watches from their window or doorstep. The same idea could be used to provide live entertainment. Audiences receive a leaflet letting them know when the float will be coming down their street. The event could be made interactive in all sorts of ways, including the use of technology, advance input, etc..

Hands-on activities: Screen time is dominating our lives at the moment, but research shows that hands on activities are vital for learning, plus promote wellbeing. Material could be delivered to audiences and they could use it to build, create art etc.. Maybe have them watch a live, or pre-recorded, show and follow along? Could the same approach allow them to contribute to these shows in some way (for instance, by carrying out some kind of experiment and submit their data. Or send in their examples of art).

Live spaces: Re-design performance spaces, such that audiences can arrive and enjoy a performance in a safe way. Maybe they sit 2 meters apart? What sorts of immersive experiences could grow from the idea?

So, those are our initial ideas. Any other thoughts?

Optical illusions

I have recently created this new video exploring psychology and optical illusions for the University of Hertfordshire. I hope you enjoy it – it features some of my favourite illusions!

Good Magic Award

[image error]I have teamed up with The Good Thinking Society to create a new award designed to promote magic for social good.

Some magicians work with disadvantaged groups, charities, hospital patients, schools, community groups, and those facing physical and psychological challenges. This work can bring lots of benefits, such as building confidence and self-esteem, inspiring happiness and optimism, supporting physical rehabilitation and co-ordination, and tackling loneliness and social exclusion. Within an educational context it can foster a greater understanding of science or mathematics, help develop critical thinking and creativity, and deliver positive messages.

The Good Magic Awards recognizes, rewards and encourages this work. Those who wish to use magic for social good are invited to apply for an award to support work in this area. Nominations will close at 5pm (GMT) on 30th April 2020, so if you think you would like to start working in this area, or need some support for an ongoing project, please head over to the site and take a look.

Puzzle 10 – Can you solve it?

[image error]

It’s our final puzzle…..

A millionaire tells his two sons to buy two horses and ride to a town 5 miles away. The one whose horse is slower wins and will inherit his fortune. After thinking about the race for days, the brothers ask a wise man for guidance. Upon receiving the advice, they jump on their horses and race to the town as fast as they can.

What did the wise man say to them?

Yesterday I posted this puzzle….

What phrases are represented here….

2 mothers and 2 daughters go out for lunch. They order 6 slices of pizza and can share the slices equally between them.

If you haven’t tried to solve it, have a go now. For everyone else, the answer is below….

If the group consists of a grandmother and her daughter and her granddaughter, then the 3 of them would constitute 2 mothers and 2 daughters. Thus the 6 pieces can be evenly shared between the 3 of them.

I hope you enjoyed the 10 puzzles. Stay safe and I hope to see you soon. Oh, and if you need the answer to the horse puzzle, here it is…..

The wise man told them to swap horses.  Given that the money will go to the slower horse, by swapping horses each son will try to get to the town first, thus creating a proper race.
