【正确答案】正确答案：Fauconnier & Turner proposes and discusses blending or integration theory, a cognitive operation whereby elements of two or more "mental spaces" are integrated via projection into a new, blended space which contains its unique structure. They present examples of blending and analyze the blending process, provide taxonomy of blends, and argue for the ubiquity and importance of blending as a cognitive resource. Blending operates on two input mental spaces to produce a third space, the blend. The blend inherits partial structure from the input spaces and has emergent structure of its own. There are some conditions needed when two input spaces one and two are blended; cross-space mapping, generic space, blend and emergent structure. The blending theory suggests a new way of thinking about what constitutes a novel inference. Because the mapping operation involves integrated frames rather than isolated predicates, the choice of one particular framing over another necessarily results in a different set of attendant inferences.
