The ability to learn and think and to adjust to the environment. A definition offered by David Wechsler (1896-1981) goes as follows: “The aggregate of global capacity of the individual to act purposefully, to think rationally, and the deal effectively with his environment (1958, p. 7).” This definition fits well with that offered by Robert Sternberg (1985) according to whom intelligence is “… mental activity directed toward purposive adaptation to, selection and shaping of, real-world environments relative to one’s life (p. 45).” Despite the closeness in defining what is intelligence, it should be borne in mind that there something in order of 70 different definitions of the construct, all of which try to go beyond the triteness of “Intelligence is what an IQ test measures.”
