All of the dual coding theoretical principles and adaptive functions are implicated in the set of cognitive abilities related to individual differences in creativity, which consist of domain-specific knowledge and innovative skills that have been hard to pin down scientifically. The emphasis here is on general processes and principles that cut across domains and individuals, analyzed in terms of DCT, with the expectation that the general principles will help explain the achievements of individual “geniuses” in their respective domains as reviewed in the next chapter. Once again the analyses reflect the constructive empiricism of the DCT approach, which relies on linking hypothetical creative processes as directly as possible to observables. This contrasts with reliance on such nonexplanatory notions as intuition and insight, which are refuges of ignorance unless they are themselves defined.
