Document Summary
Problem solving: problem solving ability is a reliable indicator of intelligence. Inductive and deductive reasoning guide the scientific method: the arch of knowledge involves creating theories ad adapting those theories through experimentation. Insight problems are best solved when you think outside the box . Insight problems can be difficult because of functional fixedness: our difficulty seeing alternative uses for common objects. When measuring intelligence, it is important to keep in mind two qualities that researchers must keep in mind: reliability, validity. 1. reliability: a reliable test produces the same result if one person takes it multiple times. It is an important quality when testing intelligence because psychologists believe intelligence is a static internal quality. 2. validity: a valid test actually measures the trait it is supposed to be measuring. Francis galton: galton"s study on reaction time established the modern study of intelligence, he would test subjects on how they could respond to sensory motor tasks by their reaction time.
