Generativity Theory

Generativity Theory is a formal, predictive theory of creative behavior in individuals. First proposed by American psychologist Robert Epstein in the early 1980s, the theory asserts that novel behavior is the result of a dynamic interaction among previously established behaviors; in other words, new ideas result from interconnections among old ones.

Generativity Theory suggests that creativity is a skill that can be learned, and specifies strategies that increase creativity and innovation: Challenging, Broadening, Surrounding and Capturing.

The theory asserts that the process of interconnection is both orderly and predictable. In a series of studies with animals and people, Epstein showed that Generativity Theory, cast into a series of equations called "transformation functions" and instantiated in a computer model, could be used to predict novel, creative behavior moment-to-moment in time in both animals and people under controlled laboratory conditions. Computer models derived from Generativity Theory generate a series of smooth, overlapping probability curves, each representing a possible behavior that can occur in a new situation, together comprising what Epstein calls a "probability profile". He also developed a new graphical technique called a "frequency profile", which demonstrates the orderliness of actual novel performances. The curves of a frequency profile can be predicted by Epstein's equations.

Epstein's research and theoretical work on this topic were summarized in a series of studies published in prestigious journals such as Science, The Proceedings of the National Academy of Sciences, and Psychological Science. Perhaps the most famous study in this series was a pigeon study called "'Insight' in the Pigeon: Antecedents and Determinants of an Intelligent Performance", published in the British scientific journal Nature in 1984. In this study, Epstein and his colleagues showed: (a) that pigeons that had been taught appropriate minimum component behaviors could solve the classic box-and-banana problem, first studied by the German psychologist Wolfgang Köhler in the early 1900s; (b) that varying the training with different pigeons led to orderly and distinctly different outcomes; and (c) that the emergence of novel behavior in this situation was orderly and predictable.
