Document Summary
All fields of human behavior use some kind of measurement. Measurement comes in many different kinds of forms. E. g. , multiple choice tests, rorschach"s inkblot test, etc. We see individual differences, even those of us animals who aren"t human. And characterization of these differences is exemplified by language (e. g. , adjectives and the lexical hypothesis) Lexical hypothesis: any important characteristics will be noticed and we will come up with a word for that characteristic. However, first recorded form of testing occurs about 4000 years ago. 2200 bc, xia dynasty, shun first emperor of china. Had his officials examined every 3 years to determine fitness for office (no details) Han dynasty: 200 bc, test batteries (2+ tests in conjunction) Used in concert with one another personality and intellect combined together tells you something about the person you are examining. There were ministers for reach of these positions. Little evidence of validity (depended on essays, poetry, penmanship)
