When people use analogies to solve problems they form an analogical mapping between
two domains of knowledge. This mapping may support inferences by analogy that
suggest a novel solution to a problem. Several factors have been proposed to be
important in selecting this mapping, from among several alternative mappings:
structural factors (systematicity and structural consistency) and pragmatic factors (the
exploitation of higher-order planning categories). We suggest another set of factors
play a role in selecting mappings: adaptability factors. Specifically, if a mapped
solution can be adapted easily to a problem, then it will be preferred over an alternative
mapping that is less adaptable.
Two experiments are reported which test the effects of pragmatic and adaptation factors;
using a novel technique in which the story analogue used has two alternative plans
either of which can be used to solve an insight problem. In Experiment 1, these plans
were varied in terms of their pragmatic-importance (success or failure) and their
adaptability. In Experiment 2, the relative adaptability of plans was manipulated.
The results suggest that there is little evidence for these specific pragmatic factors, but
that adaptability plays a definite role in selecting an analogous plan. The findings
suggest that most models need to be extended to include adaptation constraints.
