Army Mental Tests by Clarence Stone Yoakum audiobook. Genre: science Compiled and edited during the final years of World War I and published in 1920, Army Mental Tests is a practical, historically significant account of the U.S. Army's pioneering program of large-scale psychological examining. Prepared in cooperation with the Surgeon General's Office staff, Clarence Stone Yoakum (with Robert Mearns Yerkes) explains why the Army needed standardized mental testing, how the testing system was organized, and what the results suggested about recruiting, classification, and assignment of soldiers. The book walks readers through the core group examinations (including the Alpha for literate English speakers and the nonverbal Beta for illiterate or non-English-speaking recruits), outlines procedures for administration and scoring, and discusses follow-up individual examinations when group results were unclear. Beyond describing the tests themselves, it considers how these methods might be adapted outside the military, pointing toward later uses of aptitude and intelligence testing in schools and industry, while also revealing the assumptions and practical constraints that shaped early 20th-century psychometrics. --- Recommended Products --- Fruit Fly Trap - Blue Light: Zevo Flying Insect Trap Stanley Tumbler: Stanley Quencher H2.0 Memory Foam Topper: Linenspa Mattress Topper Best spray for cleaning up after pet: Natures Miracle Dog stain and Odor Remover Prime shipping is awesome: Amazon Prime Our favorite streaming device for tv: NVIDIA Shield All-new Amazon Echo Spot: Echo Spot Mens T-Shirts: Fruit of the Loom Mens Premium Clumping Cat Litter: Dr. Elseys Cat Litter *The above affiliate links are from our partners - - - - - - - - - - - - - - - - - - - - Chapters (Approximate) (00:00:00) Chapter 00 (00:13:54) Chapter 01 (00:33:36) Chapter 02 (01:19:02) Chapter 03 (02:16:19) Chapter 04 (02:44:01) Chapter 05 (03:34:30) Chapter 06 (04:20:52) Chapter 07 Learn more about your ad choices.
