which statement is true regarding the relationship between brain size and intelligence?
152885
In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. In other words, brain size accounts for between 9 and 16 percent of the overall variability in general intelligence.

The endocast showed that the brain was indeed small: relative to body size, maybe the smallest among the dinosaurs. The fact that an animal weighing over 4.5 metric tonnes (5 short tons) could have a brain of no more than 80 grams (2.8 oz) led to the idea that dinosaurs were unintelligent, an idea now largely rejected.

“Neurons also increase in size. But red blood cells are the same size whether they are in a mouse or an elephant. The reason brain and fat cells grow bigger could be because they live longer and have important long-term functions.

“Based on the results of our study, it seems likely that IQ differences will vary in scale or even direction depending on the exact type of intelligence that the test or set of tests rely most heavily upon. I would suggest that it is both more accurate and informative to measure multiple types of intelligence.”

Their research led to insights that people think in either words or images. Our preference indicated a bias in our thinking: left-brain-dominated people tend to think more in words; right-brained people tend to think more in images. ... Today, we ask the question and few realize it's even possible to think in words at all.

Anatomically, modern humans can generally be characterized by the lighter build of their skeletons compared to earlier humans. Modern humans have very large brains, which vary in size from population to population and between males and females, but the average size is approximately 1300 cubic centimeters.

According to research cited in the text, what is the relationship between giftedness and genetics? ... Whose capabilities are markedly above average and who show promise for gifted performance.

By that measure, human brains, by comparison, are seven times average. Orcas' brains are 2 1/2 times average -- similar to those of chimpanzees. ... In other words, orcas might be even much smarter than the size of their big brain suggests.

Although learning and intelligence can be conceptually distinguished in terms of formal definitions and measurements, a review of evidence on the relationship between individual differences in measures of learning and of intelligence suggests that no clear distinction can be made between the cognitive processes that ...

The male brain is wired from front to back, with few connections across the two hemispheres. Women, on the other hand, have more wiring from left to right, so the two hemispheres are more inter-connected.

Key assumptions of the biological approach: There is a direct correlation between brain activity and cognition. Biochemical imbalances can affect behaviour. Brain physiology can affect behaviour. Behaviour can be inherited (as it is determined by genetic information)

Besides the obvious size difference — the human brain is about three times larger than the chimp brain — little has been known about how the human brain and the rest of the nervous system changed in our lineage over evolutionary time.

'There's a weird urban myth that Velociraptor has a higher encephalisation quotient than humans. It clearly doesn't. 'However, the size of Velociraptor's brain in proportion to its body is relatively high compared to most reptiles, including most other dinosaurs, so it seems likely it was comparatively clever.

According to a University of Oregon study, the answer is very clear: More items stored in short-term memory is linked to greater fluid intelligence, as measured in IQ tests. The resolution of those memories, while important in many situations, shows no relationship with fluid intelligence.

In addition, we obtained evidence that once the intelligence threshold is met, personality factors become more predictive for creativity. On the contrary, no threshold was found for creative achievement, i.e. creative achievement benefits from higher intelligence even at fairly high levels of intellectual ability.

Brain-body size relationship Brain size usually increases with body size in animals (is positively correlated), i.e. large animals usually have larger brains than smaller animals. The relationship is not linear, however. Generally, small mammals have relatively larger brains than big ones.

Big dogs outperformed small dogs in certain intelligence tests in a new study. Bigger dogs had better short-term memory and self-control than smaller ones. But their size had no impact on tests of social intelligence, such as following human pointing gestures.
