How to learn by working smarter, not harder - Quartz
Learning is more effective if a lesson or experience is deliberately coupled with time spent thinking about what was just presented
For younger students, teaching someone else is a good way to practice synthesizing content after a lesson. For older students, other methods suffice: writing themes in journals, summarizing main ideas on note cards, or dictating takeaways into a phone.

Why brain training is (probably) pernicious hogwash « Computing for Psychologists
There’s a long and venerable history of unscrupulous people making money from pseudo-neuroscience – back in the 19th Century phrenology was described as “The science of picking someone’s pocket, through their skull.” I’d like to believe that some of these companies have a solid product that actually made a difference, but they all seem to have the whiff of snake-oil about them. For now I’m very much of the opinion that you’d probably be better off learning the piano, or Japanese, or even playing the latest Call of Duty. If you were really ambitious you could even try and get your kid to (Heaven forfend!) read the odd book now and again.

The vision of the brain as a computer, which I still champion, is changing so fast. The brain's a computer, but it's so different from any computer that you're used to. It's not like your desktop or your laptop at all, and it's not like your iPhone except in some ways. It's a much more interesting phenomenon. What Turing gave us for the first time (and without Turing you just couldn't do any of this) is a way of thinking in a disciplined way about phenomena that have, as I like to say, trillions of moving parts. Until late 20th century, nobody knew how to take seriously a machine with a trillion moving parts. It's just mind-boggling.

You couldn't do it, but computer science gives us the ideas, the concepts of levels, virtual machines implemented in virtual machines implemented in virtual machines and so forth. We have these nice ideas of recursive reorganization of which your iPhone is just one example and a very structured and very rigid one at that.

Excerpt from The Ravenous Brain: How the New Science of Consciousness Explains Our Insatiable Search for Meaning - Boing Boing
>> books i'll read on consciousness this summer

Consciousness concerns itself only with the most meaningful mental constructions and is ever hungry to build new patterns over existing architectures. To help in this aim, it itches to combine and compare any objects in our awareness. How the brain supports consciousness closely mirrors these functions. Those specialist regions of the cortex that manage the processing endpoints of our senses—for instance, areas involved in recognizing faces, rather than merely the colors and textures that constitute a face—furnish our awareness with its specific content. But there is also a network of our most advanced general-purpose regions that directly draws in all manner of content from these specialist regions. This is the core network, incredibly densely connected together, both internally and across major regions throughout the brain. In this inner core, multiple sources of meaningful, potentially highly structured information are combined by ultra-fast brain rhythms. And this, neurally speaking, is how and where consciousness arises.

Why Storytellers Lie - Maura Kelly - Entertainment - The Atlantic
When we tell stories about ourselves, they also serve another important (arguably higher) function: They help us to believe our lives are meaningful. "The storytelling mind"—the human mind, in other words—"is allergic to uncertainty, randomness, and coincidence," Gottschall writes. It doesn't like to believe life is accidental; it wants to believe everything happens for a reason. Stories allow us to impose order on the chaos.

"somebody, to the great irritation of Dick Nisbett, showed that you could turn people into Chinese in about six minutes, and the way that she does it is she has people read a story aloud." Wow! Can make Westerners behave more like Chinese on psychology tests described in "Geography of Thought" by priming them with a story that says "we" and "ours" a lot, against a story that says "I" and "mine" a lot. I wonder how significant this is.

New doubt on sleep's role in memory: "When the Italian patients appeared to be asleep, their EEGs suggested that their brainswere either simultaneously awake, in REM sleep and non-REM sleep, or switching rapidly between the three. Yet when subjected to a battery of neuropsychological tests, they showed no intellectual decline."
