In men the average weight is about 1370 g and in women about 1200 g. [4] [contradictory] The volume is around 1260 cm 3 in men and 1130 cm 3 in women, although there is substantial individual variation. [5] Yet another study found that adult human brain weight is 1300–1400 g for adult humans and 350–400 g for newborn humans.
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
For comparison, the average IQ is around 100. Albert Einstein and Stephen Hawking ranked close to 160. ... American psychologist Lewis Terman wrote that Mexicans, African-Americans and Native ...
The much-discussed "Flynn effect", which refers to the striking worldwide mean IQ increase over time, seemed too large to have simply reflected increased test sophistication. Possible explanations included improved nutrition and more complex environment. It was also unclear to what degree the IQ increase reflected real gain in intelligence.
Americans’ IQ scores are trending in a downward direction. In fact, they’ve been falling for over a decade. According to a press release, in studying intelligence testing data from 2006 to ...
In the United Kingdom, a study by Flynn (2009) himself found that tests carried out in 1980 and again in 2008 show that the IQ score of an average 14-year-old dropped by more than two points over the period. For the upper half of the results, the performance was even worse. Average IQ scores declined by six points.
It is believed that Homo erectus were, anatomically, modern humans as they are very similar in size, weight, bone structure, and nutritional habits. Over time, however, human intelligence developed in phases that is interrelated with brain physiology, cranial anatomy and morphology, and rapidly changing climate and environments. [9]
