IQ measures what is called the general component of human intelligence, denoted by the symbol g; it is a highly pervasive component that influences many aspects of a person’s life. To many people the items that appear on IQ tests such as the Raven’s Progressive Matrices or the Weschler tests, seem rather academic and unrelated …

The kinds of skills that mice would acquire would probably depend upon how their intelligence was measured during each culling. If you had mice running through mazes, then selective breeding, based on their success would eventually generate mice with a high capability for navigating through mazes. However, they would not develop a brain with all …
In 1904, Charles Spearman tested 23 boys in a preparatory school near Oxford on a variety of achievement tests in each of: classics, French, English, mathematics, discrimination of pitch, and music. On analyzing the test results, he asked, “What pervasive cognitive faculty accounts for the fact that a student who does well on any of …
No, IQ is defined as mental age divided by chronological age and multiplied by 100, so it is a quotient of two positive numbers and must therefore be non-negative. The normal curve that gives the distribution of IQ shows the IQ scores from 0 to an unlimited upper bound. The area under the normal curve …
No the Nazis did not develop IQ tests; these actually emerged from early efforts to identify students requiring special instruction. In 1904, Alfred Binet was the director of the psychology laboratory at the Sorbonne in Paris. The Minister of Public Education commissioned Binet to develop tests to identify less capable students who should be provided …
Mathematics at the elementary school level consists of some fundamental concepts like place value for writing numerals, and the four operations (addition, subtraction, multiplication and division) with whole numbers fractions, and decimals. These skills can be mastered by anyone of average IQ though some people of limited IQ will have to work harder than someone …

SD stands for “standard deviation.” It is a measure of how much the data deviates from the mean. For example, in most standard IQ tests, the mean IQ is 100 and the standard deviation is 15. Performance on IQ tests is closely approximated by a bell-shaped curve such that about 2/3 of the population have …
For those of us who enjoy deep abstract challenges, routine tasks like filling out forms, completing documents and other process-driven tasks are excruciatingly tedious. Becoming deeply involved in solving a mathematics problem or reading a deep analysis of a historical event is so engaging that mundane tasks, by contrast, become repugnant. During my years of …
Yes, according to Malcolm Gladwell in his book, Outliers 10,000 hours is the approximate time that a person must dedicate to practising a skill or learning a subject to reach the highest echelon of proficiency or expertise. The idea was originally expressed by psychologist K. Anders Ericsson who studied violinists. His research revealed that the …

Definitely not! Many 12-year-olds are not tuned into test-taking and make little effort toward scoring well, because they see the test as unimportant. Have her take the test in subsequent years to determine whether this was an exceptional instance and encourage her to do her best. Her performance in school and her subsequent IQ scores …
