What is computational thinking? The AI researcher Paul Rosenbloom’s interpretation focuses on two relationships: interaction (a ‘reciprocal action, effect or influence’ between two entities); and implementation (to ‘put into effect’ a system A at a higher abstraction level in terms of interacting processes within a system B at a lower level of abstraction). ‘Computational thinking’ explains how computational thinking entails more than analytical and problem solving skills. It encompasses a way of imagining, by way of seeing analogies and constructing metaphors. The influence of computational thinking on cognitive psychology and connectionism, and the emergence of cognitive science and its impact on understanding human creativity and molecular information processing are discussed.
