Age, brain size, human, intelligence, lateralization and sexA fundamental neurobiology question is whether brain size correlates with intelligence. Numerous studies have been performed to answer this question in the last 150 years. Most early studies are case reports. Many well-performed and ...
The majority of these studies showed that brain size indeed correlates with intelligence. However, various coefficients ranging mostly from 0 to 0.6 for this correlation have been reported. In this study, we will briefly review the evidence for the correlation between brain size and intelligence by...
Among humans, brain size doesn't indicate a person's level of intelligence. Some geniuses in their field have smaller-than-average brains, while others have brains that are larger than average,according to Christof Koch, a neuroscientist and president of the Allen Institute for Brain Science in ...
Intelligence can be defined as a general mental ability for reasoning, problem solving, and learning. Because of its general nature, intelligence integrates cognitive functions such as perception, attention, memory, language, or planning. On the basis of this definition, intelligence can be reliably ...
But brain weight and size have nothing to do with intelligence. What matters is what’s inside the brain.Despite its small size (about 3 pounds), the brain is able to receive and send an unlimited number of messages. It does this with the help of the spinal cord, the sense organs, ...
Evolution of human intelligence: the roles of brain size and mental construction. Two competing philosophical paradigms characterize approaches to the evolution of the human mind. One postulates continuity between animal and human behavi... Gibson,Kathleen R. - 《Brain Behavior & Evolution》 被引量:...

But smaller brain size does not necessarily mean that modern humans are less smart than their ancestors. “Modern humans simply developed different, more complex forms of intelligence,” said Brian Hare. Hare’s studies focus on two types of great apes: chimpanzees and bonobos. Both are much li...
of a large, complex brain has been the defining feature of the human lineage – although human brain size has not changed over the past 200,000 years. But it is not apparent whether the new genetic adaptations discovered in human brains have any effect on brain size, or intelligence. ...
However, not all researchers agree with McDaniel's conclusions. Such studies also raise important questions about how intelligence is defined and measured, whether relative body size is taken into account when making such correlations, and which parts of the brain should be looked at when evaluatin...
