The Limits of Intelligence

The Limits of Intelligence
Santiago Ramón y Cajal, the Spanish Nobel-winning biologist who mapped the neural anatomy of insects in the decades before World War I, likened the minute circuitry of their vision-processing neurons to an exquisite pocket watch. He likened that of mammals, by comparison, to a hollow-chested grandfather clock. Indeed, it is humbling to think that a honeybee, with its milligram-size brain, can perform tasks such as navigating mazes and landscapes on a par with mammals. A honeybee may be limited by having comparatively few neurons, but it surely seems to squeeze everything it can out of them. At the other extreme, an elephant, with its five-million-fold larger brain, suffers the inefficiencies of a sprawling Mesopotamian empire. Signals take more than 100 times longer to travel between opposite sides of its brain—and also from its brain to its foot, forcing the beast to rely less on reflexes, to move more slowly, and to squander precious brain resources on planning each step.

The Ten Most Revealing Psych Experiments Psychology is the study of the human mind and mental processes in relation to human behaviors - human nature. Due to its subject matter, psychology is not considered a 'hard' science, even though psychologists do experiment and publish their findings in respected journals. Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble.

Experts at loss to explain large jump in average IQ Older generation likely smarting over data By TODD ACKERMANCopyright 1998 Houston Chronicle Science Writer In modern memory, the younger generation rarely has had any doubt it is smarter than the older generation. Now, there may be data to suggest it's right. IQ scores are rising so dramatically, say researchers who study intelligence, that a high proportion of people considered average at the turn of the 20th century would be regarded as significantly below average by today's tests. "People are smarter now, they know more," says Cecil Reynolds, a Texas A&M University professor of neuroscience and educational psychology.

10 Brilliant Social Psychology Studies Ten of the most influential social psychology experiments. “I have been primarily interested in how and why ordinary people do unusual things, things that seem alien to their natures.Why do good people sometimes act evil?Why do smart people sometimes do dumb or irrational things?” –Philip Zimbardo Like eminent social psychologist Professor Philip Zimbardo (author of The Lucifer Effect: Understanding How Good People Turn Evil), I’m also obsessed with why we do dumb or irrational things. The answer quite often is because of other people – something social psychologists have comprehensively shown.

IQ Isn't Set In Stone, Suggests Study That Finds Big Jumps, Dips In Teens : Shots - Health News hide caption Brain researchers say the big fluctuations in IQ performance they found in teens were not random — or a fluke. For as long as there's been an IQ test, there's been controversy over what it measures.

10 Practical Uses For Psychological Research in Everyday Life People love to give each other advice. The web is full to bursting with all types of pseudo-psychological advice about life. The problem is, how much of this is based on real scientific evidence? Well, here on PsyBlog we’ve got the scientific evidence. So here’s my top 10 list of what you can learn practically from the psychological research discussed here recently. Which Measures IQ Better, ACT or SAT? What Does That Mean for Which to Take? Does the ACT or SAT measure intelligence better? What does this mean about which test you should take? One way to define IQ is the ability to solve problems based on given information. Here, we look at whether the ACT or SAT is more related to IQ (spoiler: there is an answer!) and what this means for your test-taking strategy. What Is IQ?

The Dark Side of Oxytocin, the Hormone of Love - Ethnocentrism Yes, you knew there had to be a catch. As oxytocin comes into sharper focus, its social radius of action turns out to have definite limits. The love and trust it promotes are not toward the world in general, just toward a person’s in-group. Oxytocin turns out to be the hormone of the clan, not of universal brotherhood.
