Imagination improves our performance

To improve our performance, particularly in sport, we often follow the old adage ‘practice makes perfect.’ It's known that frequently repeating the same actions can help us to become quicker and more efficient. However, according to certain scientists, mental visualization could be a better technique. For example, a goal keeper who imagines all of the different ways that the ball could arrive is more likely to respond appropriately when the time comes.

"The idea that we can train our brains to work better is all the rage across society, but our research suggests that the human brain may benefit as much, or even more, from imagining performing a task, than the brain does ...

An optical illusion explained

If you click on the photo you will discover a dress that was the object of much attention this winter. What colors do you see? This dress caused a stir on social networks this winter by creating two opposing groups: those who saw blue and black stripes and those who observed white and gold stripes. The debate caused so much controversy that researchers decided to try and find an explanation.

The team of Bevil Conway, a research professor at the ...

Does walking make us more creative?

A blank page... The worst fear of a writer or a student is when they can't find the ideas or the inspiration needed to start their work, and staring at a blank page does nothing to improve the situation. On the contrary, a blank page is likely to frustrate and provoke them even further (in this type of stand-off, the blank page always wins). However, a five minute stroll could be the answer to the dreaded writer's block.

After hearing about the advantages of sports and exercise for our intellectual capacity, walking has now come into the spotlight in particular for its creative benefits. And it's not even necessary to walk energetically, a leisurely stroll or aimless ...

What we wear influences how we think

Every morning it's the same old routine: breakfast, get dressed, get ready, and go. We do these things without thinking because we can't imagine that our clothes could have an influence on our thoughts. However, psychologists have confirmed that the way we dress not only has an impact on the way that we are perceived by others, but also on how we perceive ourselves. The clothes don't make the man….or do they?

Numerous factors have an influence on us, including the opinions of friends, teachers and even strangers. Advertising, films and books also have an impact. But who would have thought that our clothes change the way we think! These are the results of an American study ...

Sweating makes people around you happy

After reading this article, you may go easy on the deodorant... But before talking about smells, let's take a quick look at vision. It's a well-known fact that smiling and laughing are contagious. When someone smiles, you smile back. Vision thus comes into play in triggering a brain process: emotion. What if odors also had this same effect?

Because they realized that negative emotions such as fear or disgust could be transmitted from one individual to another through the smell of sweat, Gün Semin and his team at Utrecht University in the Netherlands examined the transmission of positive emotions through this same mechanism.

The experiment took place in two ...

You are probably more of an extrovert than you think you are

Do you think that your friends are more popular than you? Then you're not alone. Social psychology has found statistical evidence to support this view. Strangely, we often think that our friends have more friends than we do. This is a well-known phenomenon known as the friendship paradox.

Daniel C. Feiler and Adam M. Kleinbaum, both members of Tuck Business School at Dartmouth College, USA, conducted their research on a class of MBA students at the start of the academic year. The first study focused on the formation of social networks, while the second analyzed behavior, in particular the way that biased samples can affect decision making. Both researchers wanted to ...

Is being a mom a question of hormones?

In neuroscience, studying the impact of a molecule on behavior usually involves either adding or taking away the required molecule and observing the results. In this study, the role of oxytocin on maternal behavior was observed. Can a single hormone be responsible for the complex and varied reactions that we associate with motherhood?

When we speak about maternal behavior we automatically think of the protection and care that a mother gives her infant, behavior which is essential for many species for the survival of offspring. In this case, neuroscientists from NYU's Langone Medical Center studied the role of oxytocin on maternal behavior. Oxytocin is a hormone produced in ...

When the five senses collide

Didn't you know? It's possible to see and feel the texture of sound. It's even possible to taste a color or to hear the sound of a smell. Seems strange? For 99% of the population these statements are false. However, what happens in the brain of the other 1%? Synesthetes really experience these situations, and it's not caused by an overactive imagination.

Synesthesia is a neurological condition affecting approximately 1 in every 100 people, characterized by stronger connections between the senses. The majority of synesthetes automatically associate a letter or numbers with a color, but a wide variety of different associations are possible. This is an involuntary reaction ...

Predicting choice based on eye movement

Would you push one man off a cliff to save five others? It's an odd question… and it's actually one of the questions in the trolley problem, a famous moral dilemma in which we are forced to make a decision that inevitably leads to someone's death. Would you believe it if we told you that your response depends in part on what you’re viewing at the moment you make the decision?

Moral dilemmas and moral choice are largely used in psychology to study the criteria that influence decision-making. The response to these types of questions depends on many factors, such as cultural and individual values and the amount of time given to respond. It's less clear what influence ...

Laughter, the secret to making new friends

“Laughter is the shortest distance between two people.” It's often easy to break the tension in an embarrassing situation or establish a connection with someone we like. Except that sometimes it doesn’t work. Is laughter really a factor in bringing people together? And to what extent?

A uniquely human faculty, laughter is an important component in our society, demonstrated not only by numerous quotes, but also through the development of laughter therapies. It puts us in a good mood by reducing pain and stress, and improves health by stimulating the immune system. It not only contributes to individual well-being, but also strengthens social ties between friends... and ...
