Neurophysiologist research suggests that human thinking has two distinct phases which are complementary in making decisions or solving problems. The first, or production phase, is associated with our creative thinking- seeing the familiar in a novel way, generating a variety of ideas, and a willingness to take imaginative risks; the second, or judgment phase, kicks in our critical thinking, as the mind goes to work evaluating, distinguishing fact and evidence from sense impression, and running the tests of logic to apply what has been produced (Ruggiero, 2009, pp. 7-8). [Chapter 1: “The Brain & Mind at Work”]
Both phases of thinking can be discerned in almost any invention that marks modern life. Chester Carlson’s invention of Xerography (the Xerox Machine) in 1938 has had as much impact as any invention we could name. Do some research on his invention. A good article is found on the Great Idea Finder website [www.ideafinder.com/history/inventions/xerography.htm], or listen to the NPR program “Talk of the Nation, Science-Friday” (August 66, 2007), hosted by Mira Plato, who interviews David Owen- author of Copies in Seconds: Chester Carlson & the Birth of the Xerox Machine [http://www.npr.org/templates/story/story.php? storyId=3832375].
