The relationship of imagery to the ability to think is one of the preeminent theories of human cognition. Allan Paivio, author of the Dual Coding Theory (DCT) and a cognitive psychologist, stated, “Cognition is proportional to the extent that mental representations (imagery) and language are integrated.” Research from the 1970s and into the 1990s has validated Dr. Paivio’s work as a viable model of human cognition and its practical, as well as theoretical, application to the comprehension of language (Bell, 1991). Dr. Paivio believes that in order to think and understand, humans must be able to simultaneously generate imagery and corresponding language to describe that imagery.
Mathematics is the essence of cognition. It is thinking (dual coding) with numbers, imagery and language;
