verbal analogies, series completions, and synonyms and antonyms; roughly equivalent to verbal IQ and crystalized intelligence

what was the beta test
completing pictures, visual search, coding tasks, roughly equivalent to performance or fluid iq
30
what did yerkes group testing conclude
decline with their national background western and northern europe= higher southers and eastern europe= lower

highly correlated with time in us, english competence and schooling

reproduction and immigration control

eugenics
curbing feeble-mindedness

goddard and the kallikak family
- man had two wives - children with both - one line had feeblemindedness - goddard believed it was a well controlled comparison - feeblemindedness was controlled by a single gene

eugenics according to goddard and terman
mating should not be allowed- no feeble minded person should become a parent- main uses of IQ tests was to identify feeblemindedness so they could be brought under surveillance and protection of society
37
eugenics started way before iq tests in america so
how could immigrants have caused this

all assesments did not use iq tests assessments were done by young middle-class assistants data not collected blindly biases based on expectation, possibility of fraud
