Document Summary
Case study on sexual sterilization based on low iq. The attempt to measure intelligence began with sir francis galton (1822-1911). He believed that people with superior sensory abilities would be more sensitively attuned to the world, and be able to learn more about it. In 1884, galton created a set of 17 sensory tests and began testing people"s abilities in his anthropometric laboratory. Anthropometrics (measurement of people): methods of measuring physical and mental variation in humans. Research done by cattell revealed however, that peoples abilities on different sensory tests were not correlated with each other, or only very weakly. He also found that the students" scores on the sensory tests didn"t predict their grades, which one would expect from an indicator of intelligence. French psychologist alfred binet argued that intelligence should be indicated by more complex thinking processes such as memory, attention, and comprehension. Intelligence is defined as the ability to think, understand, reason, and adapt to or overcome obstacles.
