IQ stands for "Intelligence Quotient" which is measure of a person’s intelligence found by means of an intelligence test.
In 1906 the psychologist, Alfred Binet (1857—1911), devised the standard in relation to which intelligence has since been assessed. Binet was asked to find a method of selecting all children in the schools of Paris who should be taken out of ordinary classes and put in special classes for defectives. The problem brought home to him the need for a standard of intelligence, and he hit upon the very simple concept of "mental age. "
First of all, he invented a variety of tests and put large numbers of children of different ages through them. He then found at what age each test was passed by the average child. Binet arranged the various tests in order of difficulty, and used them as a scale against which he could measure every individual. If, for example, a boy aged twelve could only do tests that were passed by the average boy of nine, Binet held that he was three years below average, and that he had a mental age of nine.
The concept of mental age provided Binet, and through him, other psychologists with the required standard. It enabled him to state scores in intelligence tests in terms of norm. At first, it was usual to express the result of a test by the difference between the "mental" and the "chronological" age. Some however, the "mental ratio" was introduced; that is to say, the ratio of the mental age to the chronological age. Thus a boy of twelve with mental age of nine has a mental ratio of 0. 75.
The mental age was replaced by the intelligence quotient or "IQ". Clearly, since the mental age of the average child is equal to the chronological age, the average IQ is 100. [br] If a boy of 8 has mental age of 10, then his IQ will be______.
选项
A、80
B、0.80
C、1.25
D、125
答案
D
解析
本题为推断题。根据文中第四段最后两句及最后一段我们可知,“IQ”的数值是心理年龄与实足年龄的比率再乘以100。由此我们可以推算出,此题的答案应是125。故D正确。解答此题的关键就是要区分文中的“mental ratio”与“IQ”的含义以及各自的计算方法。
