Humans think and learn.
It is the scientific study of our cognitive skills. We do psychological experiments on people to see how their minds work - how quickly they can solve problems, how changes in the body and brain are related to mental changes, how people differ in their responses and how they are similar. We use computers to imitate or simulate human cognitive skills and to test theories about how the human mind works. We learn about human brains, about the different functions performed by different parts of the brain, about changes in behavior that are caused by damage to the brain. We learn about how these cognitive abilities are used in working with computers and other machines.
