his colleague, Theodore Simon, found that exams of practical information, memory,
reasoning, vocabulary, and difficulty resolving had been greater predictors of university good

easy commands and gestures, repeat spoken quantities, identify objects in photos,
determine prevalent text, notify how two objects are various, and outline summary phrases.

premiums, Binet and Simon produced the concept of psychological age, whereby, for

explained to have a mental age of twelve.
Binet’s take a look at was not widely used in France, but Henry Goddard, director of a
university for mentally challenged learners, brought it to the United States, translated it into
English, and employed it to exam folks for mental retardation. Lewis Terman, an additional
American psychologist, tailored the check for use with grown ups, proven new criteria for
common skill at every single age, and identified as it the Stanford-Binet Intelligence Scale,
