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…
Fifty years ago, the philosopher Olaf Stapledon published a novel, Sirius, which explores some of the depths of loneliness and alienation to which genetic engineering might lead. Stapledon knew nothing of DNA and molecular biology, but he foresaw the possibility of genetic engineering and saw that it would give rise…
It is not the soft power of humanity, it is not that feeble spark of benevolence which Nature has lighted up in the human heart, that is thus capable of counteracting the strongest impulses of self-love. It is a stronger power, a more forcible motive, which exerts itself upon such occasions. It is reason, principle…
Beginning to reason is like stepping onto an escalator that leads upward and out of sight. Once we take the first step, the distance to be traveled is independent of our will and we cannot know in advance where we shall end.... If we do not understand what an escalator is, we might get on it intending to go a few…
Humans, of course, were not created in a state of Original Reason. We descended from apes, spent hundreds of millennia in small bands, and evolved our cognitive processes in the service of hunting, gathering, and socializing. Only gradually, with the appearance of literacy, cities, and long-distance travel and…
At least since Dr. Spock, child-care gurus have increasingly advised against spanking.175 Today every pediatric and psychological association opposes the practice, though not always in language as clear as the title of a recent article by Murray Straus: “Children Should Never, Ever, Be Spanked No Matter What the…
In absolute numbers, of course, civilized societies are matchless in the destruction they have wreaked. But should we look at absolute numbers, or at relative numbers, calculated as a proportion of the populations? The choice confronts us with the moral imponderable of whether it is worse for 50 percent of a…
There is nothing really the matter with the concept of g; it is just that we have misused it by making it the omnipresent concept in our study of cognitive abilities. Intelligence is important on three levels, namely, brain physiology, individual differences, and social trends (collectively, BIDS). The core of a BIDS…
There is one way in which individuals can make their own luck. Internalize the goal of seeking challenging cognitive environments — seek intellectual challenges all the way from choosing the right leisure activities to wanting to marry someone who is intellectually stimulating. The best chance of enjoying enhanced…
The brain’s main job is prioritizing information relevant to our survival. Anything that suggests the possibility of danger, whether real or imagined, becomes a higher priority than anything else that is going on at that moment. This data is processed first, shifting our attention from cognitive processes down to the…
The central idea of Radical Behaviorism—that all behavior can be explained as the result of learned associations between a stimulus and a response, reinforced or extinguished through reward and/or punishment—stems from the early 20th century psychologists B.F. Skinner (at Harvard) and John B. Watson (at John Hopkins)…
Whenever a Metroid player aquires a new power-up, her mind races back in time in a way not unlike what happens at a turning point in a movie. When a secret is revealed we are forced back through the story to mentally review everything we've seen so far, sometimes changing the interpretation of entire scenes. [...]…
Music makes things in our minds, but afterward most of them fade away. What remains? In one old story about Mozart, the wonder child hears a lengthy contrapuntal mass and then writes down the entire score. I do not believe such tales, for history documents so few of them that they seem to be mere legend, though by…
Thus, your knowledge is represented in various forms that are stored in different regions of the brain, to be used by different processes. What are those representations like? In the brain, we do not yet know. However, in the field of Artificial Intelligence, researchers have found several useful ways to represent…
Chinese internet firms are definitely interested, as Ant Financial, a subsidiary of ecommercegiant Alibaba, recently showed. To its popular app Alipay it added a new service which rated a person's credit worthiness on a scale of 350 to 950 points. This score is not only determined by one's lending behavior, but also…
What happens when a mind is no longer tied to a body? What happens when those of greatest ability are enslaved by those of greatest power? What happens when Humanity is the new kid on the block? When minds are read like books and books are illegal? Shock: Social Science Fiction is a game, a set of rules, that you’re…
Felis catus is your taxonomic nomenclature, An endothermic quadruped, carnivorous by nature. Your visual, olfactory, and auditory senses Contribute to your hunting skills and natural defenses. I find myself intrigued by your subvocal oscillations, A singular development of cat communications That obviates your basic…
The DHA-deprived rats also developed signs of resistance to insulin, a hormone that controls blood sugar and regulates synaptic function in the brain. A closer look at the rats' brain tissue suggested that insulin had lost much of its power to influence the brain cells. "Because insulin can penetrate the blood–brain…
...the human organism is linked with an external entity in a two-way interaction, creating a coupled system that can be seen as a cognitive system in its own right. All the components in the system play an active causal role, and they jointly govern behavior in the same sort of way that cognition usually does. If we…
When Mike was installed in Luna, he was pure thinkum, a flexible logic--"High-Optional, Logical, Multi-Evaluating Supervisor, Mark IV, Mod. L"--a HOLMES FOUR. He computed ballistics for pilotless freighters and controlled their catapult. This kept him busy less than one percent of time and Luna Authority never…
