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.
But the control group was not all that well controlled: the brains came from people age 47 to 80 years old, whereas Einstein died at age 76. The controls brains were also fresh, whereas Einsteinâs had been languishing in basements and beer coolers for three decades.
