Ray Hyman - Hick-Hyman Law

Hick-Hyman Law

Hyman published his "classic paper showing that human choice reaction time is related to the information content of an incoming signal" called the Hick-Hyman Law. This helped to lay the groundwork "for the shift from behavioral psychology... to the era of cognitive psychology." This was Hyman's second published paper, and submitted while still a grad student. He states that Hick used a different formula and got his "math wrong, which I corrected" but they still named the law after him because Hyman was "just a student". Sometimes called Hick's Law (mainly in Britain), in America it is more often referred to as the Hick-Hyman Law.
