Beyond treating individual letters as physical objects, the human brain may also perceive a text in its entirety as a kind of physical landscape. When we read, we construct a mental representation of the text in which meaning is anchored to structure. The exact nature of such representations remains unclear, but they are likely similar to the mental maps we create of terrain—such as mountains and trails—and of man-made physical spaces, such as apartments and offices. Both anecdotally and in published studies, people report that when trying to locate a particular piece of written information they often remember where in the text it appeared. We might recall that we passed the red farmhouse near the start of the trail before we started climbing uphill through the forest; in a similar way, we remember that we read about Mr. Darcy rebuffing Elizabeth Bennett on the bottom of the left-hand page in one of the earlier chapters.
In most cases, paper books have more obvious topography than onscreen text. An open paperback presents a reader with two clearly defined domains—the left and right pages—and a total of eight corners with which to orient oneself. A reader can focus on a single page of a paper book without losing sight of the whole text: one can see where the book begins and ends and where one page is in relation to those borders. One can even feel the thickness of the pages read in one hand and pages to be read in the other. Turning the pages of a paper book is like leaving one footprint after another on the trail—there’s a rhythm to it and a visible record of how far one has traveled. All these features not only make text in a paper book easily navigable, they also make it easier to form a coherent mental map of the text.
In contrast, most screens, e-readers, smartphones and tablets interfere with intuitive navigation of a text and inhibit people from mapping the journey in their minds.”
No wonder I have such trouble getting on the e-book train despite the convenience of a kindle.

A new study by the University of Sussex finds that the repetition is important for little learners.
Dr. Jessica Horst and her researchers say that children who were read the same story three times back-to-back, instead of three different stories, actually retain 3.6 of the new words they’ve been introduced to instead of the 2.6 of the “variety” group.”
If you’re interested in making sure kids learn a lot in school, yes, intervening in early childhood is the time to do it … But if you’re interested in how people become who they are, so much is going on in the adolescent years.
It turns out that just before adolescence, the prefrontal cortex—the part of the brain that governs our ability to reason, grasp abstractions, control impulses, and self-reflect—undergoes a huge flurry of activity, giving young adults the intellectual capacity to form an identity, to develop the notion of a self. Any cultural stimuli we are exposed to during puberty can, therefore, make more of an impression, because we’re now perceiving them discerningly and metacognitively as things to sweep into our self-concepts or reject (I am the kind of person who likes the Allman Brothers). “During times when your identity is in transition,” says Steinberg, “it’s possible you store memories better than you do in times of stability.”
At the same time, the prefrontal cortex has not yet finished developing in adolescents. It’s still adding myelin, the fatty white substance that speeds up and improves neural connections, and until those connections are consolidated—which most researchers now believe is sometime in our mid-twenties—the more primitive, emotional parts of the brain (known collectively as the limbic system) have a more significant influence. This explains why adolescents are such notoriously poor models of self-regulation, and why they’re so much more dramatic—“more Kirk than Spock,” in the words of B. J. Casey, a neuroscientist at Weill Medical College of Cornell University. In adolescence, the brain is also buzzing with more dopamine activity than at any other time in the human life cycle, so everything an adolescent does—everything an adolescent feels—is just a little bit more intense. “And you never get back to that intensity,” says Casey. (The British psychoanalyst Adam Phillips has a slightly different way of saying this: “Puberty,” he writes, “is everyone’s first experience of a sentient madness.”)”
Love is the best school, but the tuition is high and the homework can be painful. As imaging studies by the U.C.L.A. neuroscientist Naomi Eisenberger show, the same areas of the brain that register physical pain are active when someone feels socially rejected….
During idylls of safety, when your brain knows you’re with someone you can trust, it needn’t waste precious resources coping with stressors or menace. Instead it may spend its lifeblood learning new things or fine-tuning the process of healing. Its doors of perception swing wide open. The flip side is that, given how vulnerable one then is, love lessons — sweet or villainous — can make a deep impression.
