Smart Drug Could Unlock Adult Brain's Ability to Learn Like a Child's, Claim US Scientists As connections in their brains are malleable, children are able to learn complex skills, such as language use, far quicker than adults can(Getty) Scientists at Stanford University claim to have discovered a drug that could give adults the ability to absorb new information like a child. Professor Carla Shatz and her colleagues Dr David Bochner and Richard Sapp discovered that by altering the brain protein PirB in mice they were able to form brain connections, synapses, more easily, boosting their capacity to learn and recover from brain damage. "To me, this is amazing because what this is saying is that it is possible to induce new synapses in adult brains," said Professor Shatz. PirB – called LilrB2 in humans – stabilises neural connections, so altering it gives the brain a child-like 'plasticity', claim the researchers. The molecule was shut down in the mice by the scientists using a new drug. However, Shatz said that the taking the proteins could be key to ensuring the brain's stability.
Vous n'avez pas confiance en vous? Vous pouvez réussir quand même Les Américains sont persuadés qu'avoir confiance en soi est le meilleur moyen de réussir. Mais c'est peut-être leur excessive confiance en eux qui leur fait croire qu'ils ont raison... Les Américains sont obsédés par la confiance en soi, et cela commence dès les premières années de leur vie. Les moindres activités pour enfants sont systématiquement présentées comme des manières de «développer l’estime de soi» du petit. La brochure d’un conservatoire de New York explique que les cours de musique sont «stimulants cognitivement» et qu’ils permettent de «développer la confiance et l’estime de soi». Accessoirement, on y apprend aussi à jouer d'un instrument. Même chose pour le karaté. Le parent américain a peur que son enfant ne s’aime pas assez. Cette relation à la confiance est assez torturée: depuis 2009, de nombreux livres –notamment Le piège de l’estime de soi et L’épidémie de narcissisme– pointent les écueils de cette obsession de la confiance.

An Illustrated Book of Bad Arguments Rationalism In epistemology, rationalism is the view that "regards reason as the chief source and test of knowledge"[1] or "any view appealing to reason as a source of knowledge or justification".[2] More formally, rationalism is defined as a methodology or a theory "in which the criterion of the truth is not sensory but intellectual and deductive".[3] Rationalists believe reality has an intrinsically logical structure. Because of this, rationalists argue that certain truths exist and that the intellect can directly grasp these truths. That is to say, rationalists assert that certain rational principles exist in logic, mathematics, ethics, and metaphysics that are so fundamentally true that denying them causes one to fall into contradiction. Philosophical usage[edit] Rationalism is often contrasted with empiricism. Theory of justification[edit] The theory of justification is the part of epistemology that attempts to understand the justification of propositions and beliefs. The other two theses[edit]
Debunkatron Warm Up Your Brain Before Work and Other Time Savers The daily commute takes 25.5 minutes each way for the average American and is generally a mindless trudge. This can result in workers showing up to the office groggy and unprepared. Rather than diving into their workload, they make their first move with a visit to Starbucks, draining the company of some productivity right at the start. The brain should be treated like the muscles in the body before a strenuous workout: Warm it up before doing heavy lifting. An entrepreneur can do the following activities to enhance the day's productivity. Related: 5 Morning Rituals to Keep You Productive All Day Long 1. There’s no better way to begin the workday than knowing exactly which tasks will be tackled upon arrival at work. A staggering number of “to-do” list apps are available but I recommend Carrot for its gamification approach to meeting deadlines. The morning commute is also the perfect time to think about major problems. 2. 3. I will admit to having an unabashed fondness for Lumosity. 4. 5.
Ne dites pas de «positiver» à quelqu'un qui déprime | Slate.fr Toutes les lignes d’écoute téléphonique comme SOS Amitié ou SOS Dépression le savent depuis longtemps, et c’est un des points fondamental de la formation de leurs bénévoles: il y a une grande différence entre écouter quelqu’un et tenter de lui «remonter le moral». Si vous avez un ami déprimé, ne lui dites surtout pas de positiver ou de garder le sourire. Une récente étude le confirme: il ne faut pas essayer de remonter le moral de quelqu’un qui déprime. Des chercheurs en psychologie de deux universités canadiennes expliquent qu’une personne déprimée et qui a une faible estime de soi rejettera toute tentative de réinterpréter ce qui lui arrive de manière positive. Les phrases comme «ça ira mieux demain» ne font qu’empirer la situation. Les personnes en souffrance préfèrent que leurs amis valident leur point de vue, même s’il est négatif. Les résultats de leur étude montrent qu’il faut plutôt encourager la personne à parler de sa souffrance, et accepter qu’elle ait des émotions négatives.
Different kinds of cognitive bias Systematic patterns of deviation from norm or rationality in judgment Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics.[1] Although the reality of most of these biases is confirmed by reproducible research,[2][3] there are often controversies about how to classify these biases or how to explain them.[4] Several theoretical causes are known for some cognitive biases, which provides a classification of biases by their common generative mechanism (such as noisy information-processing[5]). Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior.

Religion and science: Answering creationists' questions. Photo by Phil Plait After writing yesterday about the now-famous/infamous dabate between Bill Nye and Ken Ham, I don’t want to make this blog all creationism all the time, but indulge me this one more time, if you will. On BuzzFeed, there is a clever listicle that is a collection of 22 photos showing creationists holding up questions they have for people who “believe” in evolution. These questions are fairly typically asked when evolution is questioned by creationists. Some are philosophical, and fun to think about, while others show a profound misunderstanding of how science works, and specifically what evolution is. Because of this, it’s worth exploring and answering the questions presented. I’ll repeat the question below, and give my answers. 1) “Bill Nye, are you influencing the minds of children in a positive way?” I’m not Bill, but I’d say yes, he is. 2) “Are you scared of a Divine Creator?” No. 3) “Is it completely illogical that the Earth was created mature? No. Angular momentum.
