An Electric Shock is Preferable To Doing Nothing
In a recent study, participants were asked to sit alone for 15 minutes, in a room with absolutely no distractions - no phone, no book, nothing - except one: a button. The participants were told that this button would administer an unpleasant electric shock to the participant. Despite knowing this, 25% of women and 67% of men pressed the button during their time alone.
People clearly find it difficult to simply sit with only their wandering mind for company. Doing something is preferable to thinking, even if that something is unpleasant. The preference to do rather than to think, may have evolved from our animal instincts. As lead researcher Timothy Wilson told NPR: “We still have that mammalian brain that wants to engage”.
In the modern world, idle moments are rare. Smartphones offer a constant distraction from our own thoughts. We hold all of human knowledge and the ability to communicate with anyone in an instant in our pockets. The reason for the popularity of smartphones suddenly seems obvious, if even an unpleasant shock is preferable to a few moments alone.

Facebook altered News Feeds of 689,000 users for psychological experiment
In an example of how not to conduct a psychological experiment, in 2012, Facebook altered the news feeds of 689,000 users. The social media website manipulated content to make the news feed either positively or negatively emotionally charged. The study found that users posted more positive content when shown a more positive feed, and more negative content with a more negative feed. The terms of service of Facebook includes a clause stating that user’s data may be used ”for internal operations, including troubleshooting, data analysis, testing, research and service improvement”. However,  there is something distinctly off putting about a social media website manipulating the emotions of it’s users by restricting certain social content.

People will pay twice as much for a salad in the shape of a famous Kandinksy painting.
Good enough to eat? Participants in this study thought so. People were willing to pay twice as much for a salad rearranged to resemble Kandinsky’s Painting No. 201, compared to one arranged in a random heap. Both salads contained identical ingredients, and the preference stood before and after eating. It’s difficult to say why the art-inspired salad was preferred, though the researchers suggest that the diners unconsciously attributed artistic value to it, making it seem more valuable.

Why do adults speak strangely to infants?
Infant directed speech or “Mother-ese” as it’s sometimes known, describes the spontaneous change in the speech of adults when communicating with children. Voices rise in pitch and slow down, while words become linguistically simpler, exaggerated and repetitive. “Mother-ese” is quite clearly distinct from normal speech, but why do adults feel the need to change so abruptly when confronted with an infant? 
Infants show a clear predisposition for “Mother-ese”, and the modified language is beneficial to development. When given a choice, infants prefer listening to infant directed speech and are more likely to respond to similar sounds (with high pitch and a slow tempo). Infants also show improved learning when taught using infant directed speech, as opposed to adult appropriate speech. In conclusion, “Mother-ese” is a useful tool for parents to gain their child’s attention and facilitate their learning.

Peppermint’s cool and refreshing taste provides a welcome relief on warm days. The pleasant, cooling sensation associated with mojitos, mint tea and mentos is not simply imagination, but an intriguing illusion which plays on the mechanics of the brain. 
Temperature is detected by nerve endings in our skin, which projects the information to specialised warmth receptors in the brain. The temperature we feel is determined by which receptors are activated. However, these receptors can be tricked. Menthol, a chemical found in mint leaves, stimulates cold receptors, creating a feeling of coolness.
As a result, the brain responds as if you’re stepping into the shade every time you take a sip of mint tea.

Man’s Best Friend
Dogs or cats? The mere mention of this question sparks off the most enraged and volatile of arguments. Now, thanks to recent research, dog lovers can add a new weapon to their arsenal: empathy.
Eleven dogs were trained to lie in an MRI scanner while a variety of sounds were played. More activity was found in the dog’s brains when listening to human voices, rather than sounds of objects like cars or whistles. Particularly emotional sounds, like crying and laughter, produced activity in the same region of the auditory cortex of both humans and dogs.
Any dog owner will tell you of the uncanny ability to understand human emotion that our four-legged friends seem to possess.These findings, while not absolute evidence of empathy in man’s best friend, provide the first insights into the biological mechanisms underlying that mysterious connection.

Dreamcasters: how video games alter our subconscious

A fascinating article exploring the link between the virtual imaginary worlds of video games and the biological imaginary worlds that we experience in dreams. Lucid dreaming, a state where the dreamer is aware of being in a dream, is more common in gamers, possibly because of their extensive experience of made-up worlds.

Accepting that you have depression is difficult, even though it’s cliché, realising that you have a problem is the first step to solving it.

If you’re currently struggling and are becoming worried, I’d recommend watching youtuber TomSka’s video about his difficult realisation that he had depression: http://www.youtube.com/watch?v=Ds8sSeJtwYs

Caffeine Boosts Memory
Students all around the world use coffee and energy drinks to stay awake through all-night revision sessions, but new research from John Hopkins University suggests that caffeine consumption may be more effective after studying rather than before.
Dr. Michael Yassa and colleagues asked participants to memorise a set of images. They were then given either a caffeine pill or a placebo (an identical pill with no caffeine). A second set of pictures were presented the following day, which included some images shown previously and some that were different, but similar, to the first set. Usually, the similarity of the new pictures to the older ones makes it difficult to realise that they are new. The caffeine group were better at identifying these similar pictures as new than the placebo group, demonstrating that consuming caffeine enhanced their memory of the first set of images.
Don’t start downing cups of coffee after lectures though; the researchers found that 200 milligrams of caffeine was the optimum amount to improve memory. That’s about half as much caffeine as in a Starbucks “venti” sized coffee. Any more than that caused side effects, such as headaches, which prevented the enhancement in memory.
