Physical measurement of intelligence (from 1800s onwards) Sensory acuity (distinguish difference smell, sound, feelings from another) Tests show little relationship to any external criteria, or with each other. Galton"s legacy scientific/empirical approach to human intelligence. Statistical methods (created concept of statistical correlation & regression to the mean) Study of nature vs nurture (twin studies, heritability) Eugenics (well-born) - believed certain people were inherently better than others. Gathered anthropometric data (height, weight, chest size, head circumference, etc) Basis for experimental approach to mental testing. Psychiatric = intellectual abnormality a clinical issue. Psychological = intellectual abnormality a psychological issue. People who are less intelligent are not going to be accepted into society in the same way as normal people he wants people to be better integrated into society. **intelligence was considered a psychiatric issue before the time. If you were under the intelligence level, you were to go to a psychiatrist and probably never leave to be trained.
