The term self-concept is a general term used to refer to how someone thinks about or perceives themselves. It is an important term for both Social Psychology and Humanism.
IQ stands for Intelligence Quotient. It is a score that combines the mental age of a person with his chronological age. For testing purposes, the mental age is determined by a series of standardized test questions, known as the IQ test. It is estimated that well-known scientist Albert Einstein had an IQ of 160 or more.
The Stanford-Binet and Wechsler tests use the same score scale: average intelligence is between 90 and 110; genius, or gifted, is above 140; and below 70 is considered mentally deficient. The Cattell test uses a wider scoring scale, so that scores between 90 and 140 are average, and genius level IQ is over 160.n IQ test won't directly tell you how intelligent you are, but it provides insight into how well you perform in quantitative reasoning, logic and memory. There are several different types of official IQ tests available, each of which use different approaches to exploring the ways people think.
