ABSTRACT
The founder of intelligence tests, Alfred Binet, must have initially thought that creativity and intelligence were the same or closely overlapping because in the first intelligence test he devised in 1896, he used inkblots to explore the imagination of children. This chapter discusses the brain mechanism that might be important for creativity, and because intelligence appears to be a necessary component, some of the brain mechanisms that might be important for intelligence. Some intelligence tests were primarily developed to predict how well a student would perform in school, and a student's performance in school is heavily dependent on the ability to learn. To the author's knowledge, however, no one has demonstrated that the differences in human intelligence are related to the size or number of synaptic contacts, or differences in nerve growth factors, because the methods to study these variables are still not fully developed.
