Tosh Demands and Generative Thinking: What Changes and What Remains the Same?

Abstract

ABSTRACT Generative thinking can be characterized as the development of novel instantiations of existing concepts. Using this framework, the present study examined the impact of three conditions on the way subjects generated ideas about imaginary extraterrestrials. Control subjects developed alien animals but were given no special instructions. Those in the Wildly Different Condition were asked to generate creatures that were as wildly different from Earth animals as they could be. Both groups were highly and equally likely to imagine creatures that were symmetric and possessed standard senses and appendages, but the latter introduced significantly more novel variations, particularly on the number of sense organs and appendages. A third group was asked to imagine and describe things that might live on another planet, but were not initially instructed to provide drawings or limit themselves to considering living things that would be considered to be animals. This last group also preserved symmetry, but was significantly more likely to develop creatures without standard senses and appendages. Even so, 75% of this group developed creatures with standard senses and appendages. The results are discussed in terms of constraints on innovation, ways of overcoming those constraints, and the general tendency for new ideas to preserve many of the central properties of existing concepts.
