We Compile What We Read in the Context of When We Read It

Reading and experience train your model of the world. And even if you forget the experience or what you read, its effect on your model of the world persists. Your mind is like a compiled program you've lost the source of. It works, but you don't know why. [...] ...reading and experience are usually "compiled" at the time they happen, using the state of your brain at that time. The same book would get compiled differently at different points in your life. Which means it is very much worth re...

 It’s Okay to “Forget” What You Read

What we get from books is not just a collection of names, dates and events stored in our minds like files in a computer. Books also change, via our mental models, the very reality that we perceive. You can think of mental models as psychological lenses that color and shape what we see. Some of this is genetic or cultural (Americans focus on very different parts of a picture than the Japanese do), but much of our perception is also shaped by experience — and experience includes the book...

 Maintain Positive Memories and Knowledge

Other ways to celebrate and maintain positive memories and knowledge include the following: Have students teach the new skill to someone else. Have students keep a list of achievements in their math journals or write them on a wall chart. Take a photo of the fi nal achievement (even if it is something as simple as a well-solved math problem). Have students compose a note to their parents, and add your own comments. Provide opportunities for students to transfer the new skills to new situatio...

 The Myth of the Brain as a Video Camera

Before we discuss what current research tells us about memory and recall, it may be helpful to address a common misconception that emerged from the work ofCanadian neurosurgeon Wilder Penfield in the 1930s and 1940s. Penfield reported that during surgery, an electrical stimulation of the temporal lobe produced episodes of recall, almost like seeing movie clips. Many concluded that the brain ―videotaped‖ life, and to remember things, our memories simply needed to be prompted. But these epi...

 Technology is Preserving Our Ghosts

Our technology is giving us progressively greater power to keep alive our ancestors' ghosts. First the invention of writing allowed us to preserve their words. Painting and photography allowed us to preserve their faces. The phonograph preserves their voices and the videotape recorder preserves their movement and gestures. But this is only the beginning. Soon we shall acquire the technology to preserve a permanent record of the sequence of bases in the DNA of their cells. This means that we s...

 Memory Systems as a Shared Resource

This inspired them to depart from testing memory for lists of words and events, and to explore the amount of rich, in-depth information remembered by couples about experienced events. They found these social exchanges led to clear collaborative memory benefits, which could take three forms: “New information” such as finally snatching an elusive name of a musical thanks to a chain of prompts between the two parties. Richer, more vivid descriptions of events including sensory information. ...

 Couples as Socially-Distributed Cognitive Systems

In everyday life remembering occurs within social contexts, and theories from a number of disciplines predict cognitive and social benefits of shared remembering. Recent debates have revolved around the possibility that cognition can be distributed across individuals and material resources, as well as across groups of individuals. We review evidence from a maturing program of empirical research in which we adopted the lens of distributed cognition to gain new insights into the ways that remem...

 Glucose and Oxygent Improve Memory Formation

Increasing glucose and oxygen supplies to the brain seems to allow iniformation to be committed more accurately and fully to memory; in other words, you learn better. This means when you come to recall it at a later stage, you will undoubtedly do better, because the information there is clearer and more comprehensive. The reverse does not seem to be true, however. If you first encoded something without the aid of extra oxygen and glucose, suddenly making more oxygen and glucose available when...

 Human Memory, Computer Memory

Almost all of those limits start with a peculiar fact about human memory: Although we are pretty good at storing information in our brains, we are pretty poor at retrieving it. We can recognize photos from our high school yearbooks decades later, yet find it impossible to remember what we had for breakfast yesterday. Faulty memories have been known to lead to erroneous eyewitness testimony (and false imprisonment), to marital friction (in the form of overlooked anniversaries), and even death ...

 Digital Archiving Creates an Immense Wealth of History

With digital archiving in all its forms, however, a new regime of technologies for holding past experience has emerged. Our past has always been malleable, but now it is malleable with a new viscosity. Whereas in the past our experiences were frequently (literally!) pigeonholed into rigid classification systems, leading to a relative paucity of tales we could tell of our past, today the traces have multiplied and the rigid classifications are withering. (Who now does a “tree” search using...
