should influence psychology, and that it is not easy to attribute to Turing the modern-day claim
that human psychology should be computational. On the second, a clearer picture emerges.
Turing’s 1936 paper on the Entscheidungsproblem suggests that Turing machines are more
than weak models of human psychology. Putnam and others took up this idea and proposed
that Turing machines are strong models of human psychology. This idea remains influential
today. Despite the wide range of exotic computational models in cognitive science, Turing
machines still appear to capture a fundamental, albeit high level, truth about the workings of
the human mind.
