Why do we get "tip of the tongue" moments?? We’ve all experienced the tip of the tongue moment where we wanted to say something but just couldn’t remember the word. But what causes this momentary lapses in vocabulary?

Ecstasy's long-term effects revealed. "Enough time has finally elapsed to start asking if ecstasy damages health in the long term. According to the biggest review ever undertaken, it causes slight memory difficulties and mild depression, but these rarely translate into problems in the real world. While smaller studies show that some individuals have bigger problems, including weakened immunity and larger memory deficits, so far, for most people, ecstasy seems to be nowhere near as harmful over time as you may have been led to believe."

"Their idea is, in broad outline, straightforward. Dr. Crespi and Dr. Badcock propose that an evolutionary tug of war between genes from the father’s sperm and the mother’s egg can, in effect, tip brain development in one of two ways. A strong bias toward the father pushes a developing brain along the autistic spectrum, toward a fascination with objects, patterns, mechanical systems, at the expense of social development. A bias toward the mother moves the growing brain along what the researchers call the psychotic spectrum, toward hypersensitivity to mood, their own and others’. This, according to the theory, increases a child’s risk of developing schizophrenia later on, as well as mood problems like bipolar disorder and depression."

First Person Plural. "An evolving approach to the science of pleasure suggests that each of us contains multiple selves—all with different desires, and all fighting for control. If this is right, the pursuit of happiness becomes even trickier. Can one self bind another self if the two want different things? Are you always better off when a Good Self wins? And should outsiders, such as employers and policy makers, get into the fray?" [Via]

"Imagine what it would feel like—or think back to what it felt like—when your body and mind are telling you you're an adult while the adults around you keep insisting you're a child." An interview with psychologist Robert Epstein, who argues that American teens are far more intelligent, capable, and moral than we give them credit for. His new book, The Case Against Adolescence, suggests that infantilization of teens leads to psychological problems. See also Epstein's article "The Myth of the Teen Brain" [PDF] from Scientific American Mind.

Neurogenesis Neurogenesis, the birth of new brain cells, was something we were all taught was impossible after a certain point. Professor Elizabeth Gould, doctor of psychology at Princeton, has claimed that it happens all the time. (more) Now, she and her team at Princeton are saying not only is our brain always changing, stress and environment directly affect brain development.

You are very bad at making decisions. Welcome to the world of cognitive biases. They are why it is so easy to see conspiracies in the death of microbiologists, to be unaware of how incompetent we are, to regret our bids on eBay, and to be superstitious rationalists. Perhaps you should learn to use them before you are taken in. Finally, cognitive biases are why you will remember the end of this po

The McCollough effect is a visual illusion somewhat similar to regular color aftereffects, but the working mechanism is different, and despite a wealth of theories, not entirely explained. Once the effect is established, it does not seem to go away and can last for days or even weeks. Proceed at your own risk.
