Human intelligence is being defined and measured for the first time ever, by researchers at the University of Warwick. Led by Professor Jianfeng Feng in the Department of Computer Science, studies at Warwick and in China have been recently undertaken to quantify the brain's dynamic functions, and identify how different parts of the brain interact with each other at different times -- namely, to discover how intellect works.

The combination of human and artificial intelligence will define humanity’s future PDF Versão para impressão Enviar por E-mail

Through the past few decades of summer blockbuster movies and Silicon Valley products, artificial intelligence (AI) has become increasingly familiar and sexy, and imbued with a perversely dystopian allure. What’s talked about less, and has also been dwarfed in attention and resources, is human intelligence (HI). In its varied forms — from the mysterious brains of octopuses and the swarm-minds of ants to Go-playing deep learning machines and driverless-car autopilots — intelligence is the most powerful and precious resource in existence.

IQdb: an intelligence quotient score-associated gene resource for human intelligence PDF Versão para impressão Enviar por E-mail

Intelligence quotient (IQ) is the most widely used phenotype to characterize human cognitive abilities. Recent advances in studies on human intelligence have identified many new susceptibility genes. However, the genetic mechanisms involved in IQ score and the relationship between IQ score and the risk of mental disorders have won little attention. To address the genetic complexity of IQ score, we have developed IQdb, a publicly available database for exploring IQ-associated human genes. In total, we collected 158 experimental verified genes from literature as a core dataset in IQdb. In addition, 46 genomic regions related to IQ score have been curated from literature. Based on the core dataset and 46 confirmed linked genomic regions, more than 6932 potential IQ-related genes are expanded using data of protein–protein interactions.

Life Extension Factor Klotho Enhances Cognition PDF Versão para impressão Enviar por E-mail

In a paper just published in Cell Reports, Dena Dubal, Lennart Mucke, and their colleagues provide strong evidence that klotho enhances cognitive function, separate from its effects on aging. They started by looking at humans carrying an interesting variant of the KLOTHO gene. The variant was known to be associated with increased longevity, and the authors show that it leads to higher levels of klotho in the blood. Moreover, they show that carriers of the variant exhibit enhanced cognition, scoring higher on multiple tests of various aspects of cognitive function. The results suggest that systemic increases in klotho levels can improve cognitive function. So the authors took the experiments into mice. They found that elevation of klotho levels leads to improved learning and memory, seen in various tasks and shown not to be age-dependent. They went on to describe specific effects on synaptic function and plasticity that may account for the cognitive changes.

The relationship between intelligence and creativity PDF Versão para impressão Enviar por E-mail

The relationship between intelligence and creativity has been subject to empirical research for decades. Nevertheless, there is yet no consensus on how these constructs are related. One of the most prominent notions concerning the interplay between intelligence and creativity is the threshold hypothesis, which assumes that above-average intelligence represents a necessary condition for high-level creativity. While earlier research mostly supported the threshold hypothesis, it has come under fire in recent investigations.

What is giftedness? What is talent? PDF Versão para impressão Enviar por E-mail

There seem to be infinitely variable definitions for these two words. Let's start with the idea of intelligence. Most research suggests that the higher an individual's intelligence, the greater the degree of cognitive, emotional, and spiritual complexity there will be in that person's encounter with the world. In our culture, we tend to award achievement: the highest GPA, the best job, the most academic degrees, and the most money. Giftedness, however, is not about achievements in that sense.

g and the measurement of Multiple Intelligences: A response to Gardner PDF Versão para impressão Enviar por E-mail
Escrito por B.A. Visser et al   
Segunda, 04 Novembro 2013 18:22

Gardner [Gardner, H. (2006-this issue). On failing to grasp the core of MI theory: A response to Visser et al. Intelligence] criticized some aspects of our empirical examination [Visser, B. A., Ashton, M. C., & Vernon, P. A. (2006-this issue). Beyond g: Putting multiple intelligences theory to the test. Intelligence] of his “Theory of Multiple Intelligences”. Specifically, Gardner questioned the construct validity of g, and suggested that the measures we used to test his theory were contaminated with verbal and logical demands. In this reply, we explain that the construct validity of g is well established, pointing out (a) that g is expressed in a wide variety of tasks (not all of which are “school-like” tasks), (b) that g predicts many important criterion variables (not only academic achievement), and (c) that g has a well-established biological basis. With regard to the measures used in our study, we point out that the verbal content of those tasks is unlikely to contribute to individual differences in task performance, and that the logical content of those tasks is consistent with Gardner's description of his intelligence domains.

"I would be willing to wager that if an average citizen from Athens of 1000 BC were to appear suddenly among us, he or she would be among the brightest and most intellectually alive of our colleagues and companions. We would be surprised by our time-visitor's memory, broad range of ideas and clear-sighted view of important issues. I would be willing to wager that if an average citizen from Athens of 1000 BC were to appear suddenly among us, he or she would be among the brightest and most intellectually alive of our colleagues and companions. We would be surprised by our time-visitor’s memory, broad range of ideas and clear-sighted view of important issues. I would also guess that he or she would be among the most emotionally stable of our friends and colleagues. I do not mean to imply something special about this time in history or the location, but would also make this wager for the ancient inhabitants of Africa, Asia, India or the Americas of perhaps 2,000 to 6,000 years ago. I mean to say simply that we Homo sapiens may have changed as a species in the past several thousand years and will use 3000 years to emphasize the potential rapidity of change and to provide a basis for calculations, although dates between 2,000 and 6,000 years ago might suffice equally well. The argument that I will make is that new developments in genetics, anthropology and neurobiology make a clear prediction about our historical past as a species and our possible intellectual fate. The message is simple: our intellectual and emotional abilities are genetically surprising fragile."
