intelligence quotient (redirected from school age)

quotient /quo·tient/ (kwo´shent) a number obtained by division.

achievement quotient  the achievement age divided by the mental age, indicating progress in learning.

caloric quotient  the heat evolved (in calories) divided by the oxygen consumed (in milligrams) in a metabolic process.

intelligence quotient  a measure of intelligence obtained by dividing the mental age by the chronological age and multiplying the result by 100.

respiratory quotient  (RQ) the ratio of the volume of carbon dioxide given off by the body tissues to the volume of oxygen absorbed by them; usually equal to the corresponding volumes given off and taken up by the lungs.

n. Abbr. IQ

An index of measured intelligence expressed as the ratio of tested mental age to chronological age, multiplied by 100.

intelligence quotient (IQ),

a numeric expression of a person's intellectual level as measured against the statistical average of his or her age group. On several of the traditional scales, it is determined by dividing the mental age, derived through psychologic testing, by the chronologic age and multiplying the result by 100. Average IQ is considered to be 100. Compare achievement quotient. See also accomplishment quotient.

intelligence [in-tel´ĭ-jens]

the ability to comprehend or understand. It is basically a combination of reasoning, memory, imagination, and judgment; each of these faculties relies upon the others. Intelligence is not an entity within a person but a combination of cognitive skills and knowledge made evident by behaviors that are adaptive.

In speaking of general intelligence, authorities often distinguish between a number of different kinds of basic mental ability. One of these is verbal aptitude, the ability to understand the meaning of words and to use them effectively in writing or speaking. Another is skill with numbers, the ability to add, subtract, multiply, and divide and to use these skills in problems. The capacity to work with spatial relationships, that is, with visualizing how objects take up space, is still another (for example, how two triangles can fit together to make a square). Perception, memory, and reasoning may also be considered different basic abilities.

These abilities are the ones that are usually examined by intelligence tests. There are others, however, that may be as important or more important. Determination and perseverance make intelligence effective and useful. Artistic talent, such as proficiency in art or music, and creativity, the ability to use thought and imagination to produce original ideas, are difficult to measure but are certainly part of intelligence.

intelligence quotient (I.Q.) a numerical expression of intellectual capacity obtained by multiplying the mental age of the subject, ascertained by testing, by 100 and dividing by his or her chronologic age.

intelligence test a set of problems or tasks posed to assess an individual's innate ability to judge, comprehend, and reason.

intelligence quotient IQ; a numerical expression of intellectual capacity obtained by multiplying the mental age of the subject, ascertained by testing, by 100 and dividing by the chronological age.

respiratory quotient RQ; the ratio of the volume of carbon dioxide given off by the body tissues to the volume of oxygen absorbed by them; usually equal to the corresponding volumes given off and taken up by the lungs. It varies with the fuel source used: for carbohydrates it is 1.0; for lipids 0.7; for proteins 0.8; and with overfeeding (lipogenesis) 1.0–1.3.

intelligence,

n mental potential or capacity; an individual's total repertoire of problem-solving and cognitive discrimination responses that are usual and expected at a given age level and in the large population unit; that which is measured by an intelligence test.

intelligence dental, quotient,

n an estimated appraisal of a patient's knowledge and appreciation of dental services.

intelligence quotient (IQ),

n an estimate of intelligence level; an index determined by dividing the mental age in months by the chronologic age in months and multiplying the result by 100. Thus the IQ of a child of 100 months with a mental age of 110 months would be 110.
