Psychometry is the art of measuring the duration or time relations of cognitive processes, or otherwise quantifying cognitive phenomena and applying a scaling mechanism as a means of comparison between results. Psychometric tests include intelligence tests, vocational tests, personality tests etc. Some examples are the American School Intelligence Test
, various academic aptitude tests, the Apperceptive Personality Test, the Bacon-Lerner Vocational Role Index, etc.
It should be noted that psychometric tests lack ecological validity
, so the generalisability of the test results should always be carefully considered.
