an American psychologist and computer scientist. While affiliated with Carnegie Mellon University in the late 60s, he worked with Herbert Simon on perceptual processes in problem solving, and developed a program dubbed Perceiver based on previously developed routines of the program Mater  for detecting basic chess relations of attack and defense, to simulate the eye movements of a chess expert over a 5-second interval scanning a chess position preparatory to making a move .
