Intelligence: the ability to learn and to meet the demands of the environment e ectively. Metacognition: ability to understand and control ones mental activities. Keys for good intelligence tests: reliability, validity, standardization. Reliability: refers to consistency in measurement: test-retest reliability: same test to same people and correlate scores, internal consistency: all items should measure the same thing, interjudge reliability: consistency of measurement when di erent people score the same test. Thought of the theory of psychophysical performance. This the the thought that tested sensory processing, motor skills and reaction time. Believed in development of the rst standardized intelligence test. Mental age: the age at which an individual is performing intellectually. Used binet"s mental age to develop intelligence quotient (iq) Used factor analysis to determine the structure of intelligence. There is a di erence between mental and chronological age and it becomes less informative with age increase. They do not want to have language barriers to cloud iq scores.
