Description
th WK3 –Lec#2 – January 22 , 2013 History of Psychological Testing ● According to Robert j. Gregory: ○ "Students of psychology normally regard historical issues as dull, dry, and pedantic, and sometimes these prejudices are well deserved" ○ "In reality, the history of psychological testing is a captivating story that has substantial relevance to present-day practices" (p.41) Historical Timeline ● Han Dynasty (2220 BC) - 1st idea of test selecting ppl ● Physiognomy and Phrenology (384 BC/1810) ● Charles Darwin and Sir Francis Galton (~1859-1883) ○ Impact on western society ● Experimental Psychology and Psychophysical Measurement (~1886-1912) ○ UofT has a huge history of this ● Intelligence Tests (~1905-1930s) - selection, education ● Personality and Vocational Tests (1920-1940s) Rudimentary forms of testing in china in 2200 BC ● Emperor had his officials examined every 3rd year for fitness for office -> did it work? ● Written exams were introduced in the Han dynasty to test civil law, military affairs, agriculture, revenue, and geography ● * final form of Chinese Examination System - going into political office, first formal testing for specific purposes ○ Round 1: spend one day and night in a small isolated booth composing essays on assigned topics and writing a poem ○ Round2: three separate sessions of 3 days and 3 nights ○ Round3: travel to Peking for a final round of examinations to finally become mandarins eligible for public office  Found to be: unnecessary, gruelling, and wasn't validated (abolished in1906 by royal decree)  Their writing; prose, intelligence, writing style showed their competence for office, but was it really accurate or necessary?  Modern day GRE: validated, shows an incremental validation Physiognomy Based on notion that we can judge the inner character of ppl from their outward appearance ● Still studied today ● Can tell personality traits just by glancing at the face ○ Ex.
